Why choose a custom theme over a template

Templates are fine for quick, one‑off sites. But if you care about speed, editing control, security, and room to grow, a custom theme is the smarter long‑term move—one that usually pays for itself in fewer headaches and better results.

• Intentional performance: We plan for Core Web Vitals from day one with lean code, a minimal plugin footprint, optimized assets, and smart caching so pages load fast on any device. Result: better SEO, higher conversions, happier users.
• Editing clarity: Built for the block editor. Custom blocks and patterns match your content model (Services, Testimonials, Locations), so your team adds content instead of fighting layout. Brand‑safe styles and permissions keep everything consistent.
• Security and reliability: Fewer moving parts mean fewer vulnerabilities. We use vetted dependencies, a clear update path, and ship code we can audit and maintain. Less risk, more uptime.
• Real scalability: A modular setup with components, custom post types, and reusable patterns lets us add features or integrations later without rework or page‑builder debt.
• Accessibility built in: We follow WCAG 2.1 AA using semantic HTML, proper contrast, keyboard navigation, visible focus states, and ARIA where needed—validated with automated and manual testing. Good for users, good for compliance and SEO.
• True ownership: You own the code. No proprietary frameworks, no page‑builder lock‑in, and no recurring licenses just to keep editing. We deliver your theme in a Git repository with documentation and handoff training.

Our approach and engineering standards

Discovery and architecture

We start by listening. Workshops define goals, audiences, and success metrics. We inventory content, map information architecture, and design a content model with custom post types, taxonomies, and fields that fit how your team works. We set performance budgets early, for example LCP under 2.5s, CLS under 0.1, INP under 200ms on common networks, so design and engineering decisions stay tied to speed, accessibility, and maintainability. The outcome is a clear, lightweight plan everyone can approve quickly—fewer surprises, faster timelines. If you’re considering a redesign, let’s begin with a 15-minute discovery call to confirm scope and fit.

Design fidelity

We build what is in your Figma, PSD, or XD, including spacing, states, and micro‑interactions. Responsive breakpoints are based on your analytics and real devices. We document a browser support matrix and ensure typography, grids, and components scale smoothly, without surprises at intermediate widths. No “close enough” implementations—your stakeholders see exactly what was approved. Need help closing a design gap? We can collaborate with your designer or step in to finalize components.

Build

Our themes are hand‑coded with a block editor first approach. We use theme.json to centralize color, typography, spacing, and layout controls, keeping the editor consistent and on brand. Native Gutenberg blocks and custom patterns come first, and we add custom blocks where they add clear value. Structured content uses ACF and custom post types when appropriate. Code is clean and lean: PHP that follows WordPress standards, modern JS, and SCSS compiled to minimal, tree‑shaken assets. We keep the plugin footprint small. That means no page‑builder lock‑in, faster pages, and an editor experience your team can actually use. Want to see code quality before we start? Ask for a sample repo or snippet.

Quality and performance

Every build passes automated checks, including PHPCS with WP standards, ESLint and Stylelint, image and asset linting, and Core Web Vitals audits. We test across modern browsers and a range of iOS and Android devices. Accessibility is verified against WCAG 2.2 AA with keyboard‑only navigation, contrast checks, and screen reader spot checks. Security best practices are built in with capability checks, nonces, and sanitized inputs. We optimize media with responsive images and modern formats and add a CDN when hosting allows. This rigor translates to better search visibility, higher conversions, and fewer support headaches. Not ready for a rebuild? Ask about a standalone performance and accessibility audit.

DevOps

Workflows run through Git with feature branches and code review. You get a staging environment that mirrors production for acceptance testing. Deployments are scripted and repeatable, with database and content migration procedures, automatic backups, and a clear rollback plan. Go‑lives are calm, traceable, and reversible—bring your own host or we’ll recommend one and adapt to your compliance needs.

Launch, training, and documentation

We manage a content freeze window, final QA, and a go‑live checklist. Your team receives editor training, short video walkthroughs, and a concise admin guide covering content types, blocks, patterns, and permissions. We add field‑level guidance in the editor so new team members can self‑serve. Prefer ongoing help? We offer support plans, but you’ll never be dependent on us for everyday edits.

Optional headless or decoupled architectures

When you need app‑like experiences or multi‑channel content delivery, we can run WordPress headless via REST or WPGraphQL and power a front end such as Next.js. You still get editorial previews, role permissions, and fast cache invalidation, while meeting performance budgets. We’ll tell you when headless truly pays off—and when a well‑engineered traditional build is the smarter play.

Ready to map this approach to your site? Email jc@stlcodescape.com or call 314-657-7421 to schedule a quick consult.

An editing experience your team will actually enjoy

Updating your site should not require a developer—or a prayer. We shape the WordPress block editor around your real content so your team can add pages in minutes without breaking layouts or drifting off brand. Choose the content type, fill in guided fields, drop in approved blocks, preview, then publish. Want to see it in action? Ask for a quick 10‑minute editor demo.

• Custom blocks and patterns that mirror your content types and design system. Examples include Service, Location, Event, Case Study, Team Member, and Testimonial blocks with the exact fields you need, plus prebuilt page patterns that assemble them into consistent, on‑brand layouts. Tell us what your team publishes most—we’ll make that the easiest path.
• Reusable components and content guidelines for brand consistency. We lock in typography, color palettes, spacing, and image ratios. Helpful side‑panel notes surface character counts, recommended image sizes, and examples so copy and visuals stay on message—even when you’re moving fast.
• Role‑based permissions and guardrails to prevent layout breakage. Template and block locking, allowed‑block lists, and sensible defaults let Authors edit content safely, while Editors and Admins control structure. Edit with confidence; no “whoops, broke the homepage” moments.
• Inline help, block hints, and short video walk‑throughs. Contextual tips appear where people work, and a small video library—one to three minutes each—covers common actions like adding a landing page, swapping hero media, or updating navigation. Zero guesswork, zero hunting through docs.
• Training session included, with handoff materials your team can reference anytime. We host a live onboarding for your editors and leave a searchable guide with screenshots, steps, and links to those videos. New hires ramp quickly, and your power users get power tips.

The result is a calm, repeatable workflow that empowers nontechnical editors and protects your brand—without plugin clutter or surprises. Ready to give your team an editor they’ll actually enjoy? Schedule a quick demo at 314-657-7421 or jc@stlcodescape.com. Next, how we handle performance, security, and SEO.

Performance, security, and SEO—engineered together

Great code is only half the battle. We design your theme so speed, safety, and search visibility reinforce each other from day one, without piling on plugins or hacks. The result: a site that loads fast, stays locked down, and is crawlable out of the box—so you get more conversions with less ongoing drama. Want a quick read on where you stand today? Ask for a no-pressure performance and security baseline.

Performance

Fast pages convert. We engineer speed into your architecture—not as an afterthought.

• Core Web Vitals as a build target. We track LCP, CLS, and INP throughout development and set budgets so regressions are caught before launch.
• Lean assets only where needed. Conditional script and style enqueues, code splitting, critical CSS, deferring nonessential JS, and resource hints like preconnect and preload for key fonts and APIs.
• Image pipeline you do not have to think about. Automatic AVIF or WebP generation with fallbacks, responsive srcset and sizes, intrinsic dimensions to prevent layout shift, and native lazy loading.
• Caching and CDN matched to your stack. Full‑page and object caching such as Redis, HTTP/3 and Brotli at the edge, smart cache keys, and automatic purges on content updates. We also review database queries and server TTFB to remove bottlenecks.

Need managed hosting and CDN support as part of your stack? Explore our Hosting Solutions.

Curious what this could do for your stack? Book a 15‑minute technical consult and we’ll outline the wins we can deliver.

Security

Sleep easier with a site that’s hardened by default—and monitored going forward.

• Hardened admin by default. Least‑privilege roles and capabilities, disabled file editor, rate‑limited logins, optional IP allowlisting for wp‑admin, and locked down XML‑RPC.
• Vetted, pinned dependencies. Minimal plugin footprint, version pinning, and vulnerability scanning before production.
• Updates and backups with a safety net. Scheduled core and plugin updates go through staging first. Daily encrypted offsite backups with multi‑day retention and tested restore procedures.
• Extra layers when needed. Two‑factor auth for admins, WAF or CDN protections such as Cloudflare, security headers like HSTS and CSP where applicable, audit logs, and reCAPTCHA on forms.

Need a hardening pass before your next campaign? We can implement these protections quickly—even if we didn’t build your site.

SEO

Technical SEO is built in, so your content has a fair shot from day one.

• Clean, semantic HTML that search engines and assistive tech understand. Correct heading hierarchy, landmarks, and accessible navigation.
• Structured data included. JSON‑LD for Organization or LocalBusiness, BreadcrumbList, Article, Product, or Event, tied to your content fields so editors can manage it.
• Technical foundations handled. Human‑readable URLs, canonical tags, meta titles and descriptions, Open Graph and Twitter cards, XML sitemaps, and a robots.txt tuned for your environment with staging blocked.
• Migration‑safe practices. 301 redirect mapping, consistent 404 handling with logs, and rules for noindex and pagination to keep thin or duplicate pages out of the index.

Local business? See how we approach Local SEO fundamentals.

Ongoing monitoring

Your site keeps improving because we keep watching.

• Real‑user and lab data. Core Web Vitals from field data, Lighthouse checks in CI, and alerts when budgets are exceeded.
• Uptime and error visibility. 24 by 7 uptime monitoring, server and application error logs, and optional Slack or email alerts.
• Continuous care. Monthly reports and tune‑ups through our website management plans so performance, security, and SEO stay aligned as your site evolves.

Join a Website Management plan and keep everything fast, secure, and findable month after month.

Share a view link or email your files to jc@stlcodescape.com for a feasibility check and a clear estimate—usually within one business day. Prefer to talk it through? Call 314-657-7421.

Design‑to‑WordPress conversion (Figma, PSD, XD)

Already have the designs? Hand them off and we’ll turn your Figma, PSD, or XD files into a lean, custom WordPress theme—no page builders, no bloat—so what you approved in design is exactly what ships in code. Share your files for a fast, fixed‑scope estimate and timeline. Agency partner? We’re happy to work under NDA and slot into your workflow—see our Advertising Agency collaboration model.

• Pixel accurate and responsive. We reproduce your typography, spacing, grids, and states exactly, and define responsive behavior with breakpoints, fluid type and space, and container‑aware layouts so components adapt cleanly across devices—no surprises at QA.
• Accessibility included. Components use semantic HTML, ARIA only where needed, proper focus states and order, skip links, and full keyboard navigation. We validate color contrast against WCAG 2.1 AA and ensure forms, menus, and modals work with assistive tech.
• Motion that respects performance. We implement animation and micro‑interactions with CSS transforms or SVG where possible, async JS when needed, no render‑blocking, and prefers‑reduced‑motion support so effects feel polished without hurting Core Web Vitals.
• Your design system, codified. Design tokens for colors, typography, spacing, radii, and shadows map to theme.json and appear as block styles or variations. Editors get a curated palette and locked styling options to keep brand consistency.
• Editor‑friendly components. Reusable blocks and patterns mirror your design components, with ACF fields and custom post types where structured content is required, making updates fast, safe, and on brand.
• Rigorous handoff and QA. We provide a staging site, visual diffs against comps, cross‑browser and device testing, and acceptance criteria tied to your designs before launch—so you can ship with confidence.

If your designs include product catalogs, checkout flows, gated content, or data touchpoints, we wire them up next. WooCommerce templates, payment, shipping, and tax, plus integrations with CRMs and marketing tools.

Not sure if your file is dev‑ready? We’ll do a quick review and flag gaps before we start. Send your Figma link to jc@stlcodescape.com or call 314-657-7421 to get a fast estimate and kickoff.

WooCommerce and business integrations

We build WooCommerce stores that feel fast, findable, and easy to buy from—so more visitors convert and fewer abandon. Themes are hand‑coded to minimize JavaScript, reduce cart‑fragment overhead, and pass Core Web Vitals. Product discovery is intentional with faceted and category filters, strong on‑site search, structured data for rich results, and reusable product cards or blocks you can place anywhere. Checkout is streamlined with auto‑apply coupons when appropriate, guest checkout, address autocompletion, Apple Pay or Google Pay where supported, and clear error states so fewer shoppers bounce. If your current store feels heavy or slow, we’ll de‑bloat it and show you the speed gains before launch.

We configure the commerce essentials end to end

• Payments: Stripe, PayPal, Authorize.Net, Square, Apple Pay or Google Pay via Stripe, SCA or 3DS as needed—set up to reduce fraud and failed payments.
• Tax and shipping: zones and rules, live rates with UPS, FedEx, USPS, TaxJar or Avalara, ShipStation or Shippo labels and tracking—so quotes are accurate and fulfillment stays on time.
• Transactional email: branded order and shipping templates, SPF or DKIM or DMARC alignment, and deliverability monitoring so confirmations reach the inbox and reduce support tickets.

Your marketing and analytics stack connects cleanly without bloat. We map forms and orders to HubSpot or Salesforce, including objects, fields, and lifecycle stages, sync audiences with Mailchimp or Klaviyo, and implement GA4 or GTM with an ecommerce‑ready data layer, consent mode, and event naming your team can report on. You get trustworthy data and campaigns that actually attribute revenue. Want us to sanity‑check your current tracking? Ask for a quick analytics audit.

When your site needs to talk to the rest of the business, we build reliable integrations, not just plugins. That includes REST or SOAP connections to ERPs like NetSuite, Dynamics, SAP B1, inventory or POS, PIM or DAM, events, or booking systems. We design for data integrity with webhook listeners, idempotent writes, queued or retry logic for rate limits, field‑level mapping, and audit logs, plus an admin dashboard for manual replays. If traffic or risk warrants it, we offload to lightweight middleware so WordPress stays responsive. The result: fewer manual touchpoints, fewer stock issues, and fewer late‑night fires. See our Business Process Automation approach.

All integrations are documented, version‑controlled, and owned by you, with a minimal plugin footprint and ongoing monitoring. We can also add modern AI features such as smarter search, product recommendations, and support automations to improve UX and team productivity. Explore our AI Integrations to see what’s possible. Have a complex stack or a migration on your roadmap? Let’s map it out in a 15‑minute call—314-657-7421 or jc@stlcodescape.com.

Explore AI Integrations

AI integration and workflow consulting

We add AI where it helps, inside your WordPress theme and your editorial workflow, without hurting performance, privacy, or editorial control. We start small—identify high‑impact use cases, pilot them safely, then scale what proves value. Learn more about our AI integrations for WordPress.

On‑site chatbots for support and lead qualification

Trained on your content, including pages, posts, docs, FAQs, and PDFs, and tuned to your brand voice. The bot can answer common questions, qualify leads with custom flows, capture contact details, book meetings, and hand off to a human when confidence is low. We wire in analytics, your CRM or marketing automation, and clear consent—and we’ll define success metrics before launch. Want to see it in action? Check our Custom AI Chatbot Setup and ask for a quick demo.

Content automation assists that keep editors in charge

In‑editor helpers create briefs from target keywords, suggest headlines and meta descriptions, draft alt text, and recommend internal links. Optional QA checks flag reading level, broken references, and off‑brand tone. Nothing auto‑publishes. Editors review and approve, with change tracking and role‑based permissions. Prefer your current workflow? We’ll meet you there and streamline it—book a short workflow mapping session.

Smarter search and recommendations

Semantic site search understands intent and synonyms and surfaces the most relevant pages, posts, or products. We add related content or product blocks and next‑step nudges that respect your business rules—for example, prioritize cornerstone content or exclude gated assets. For WooCommerce, we enable complementary and similar product recommendations with caching to keep speed up. Let us run a relevance tune‑up and show you how it impacts engagement.

Privacy, data handling, and approvals by design

Sensitive data is scrubbed before model calls. API keys live server side. We can use US or EU hosted providers or self‑hosted models when required. We prevent training on your private data by default, set explicit retention windows for logs, and maintain an approval workflow with audit trails so every AI‑assisted change is attributable and reversible. You stay compliant and in control. See how we approach GDPR/HIPAA compliance with AI and secure connections to databases/APIs.

At launch, you receive clear documentation of models and providers used, a data flow map, prompt libraries and tone guidelines, chatbot fallback and escalation rules, updated privacy or consent language, and editor training—so your team can own it from day one.

Curious what this could look like on your site? Book a 30‑minute consult or request a live demo: 314-657-7421 or jc@stlcodescape.com.

What you get at launch

At launch you get a complete, documented package your team can run with from day one—no guesswork, no vendor lock‑in, and a clear path to results.

• Custom theme codebase in your repo, with documentation and license details. We push the hand‑coded theme, and child theme if used, to your GitHub, GitLab, or Bitbucket repository with a clear README, build scripts, theme.json, coding standards notes, a changelog, and a LICENSE file that spells out ownership of custom code and any third‑party licenses. Deployment instructions and rollback steps are included—so you own it, you control it, and you can ship confidently.
• Block or pattern library, style guide, and editor training recordings. You get a curated set of Gutenberg blocks and reusable patterns mapped to your content types, a brand style guide for colors, typography, spacing, and components, and short how‑to docs. We also provide recorded training sessions so new editors can get up to speed quickly—publish new pages in minutes and keep everything on‑brand.
• Performance and accessibility reports with recommendations and next steps. We deliver a launch report covering Core Web Vitals and Lighthouse, TTFB, page weight, request counts, caching and CDN setup, plus a WCAG 2.2 AA scan using axe or Pa11y. You get a prioritized list of quick wins and longer‑term optimizations—know exactly what to do first for the biggest impact. Want to preview a sample report? Just ask.
• Analytics or tag manager configuration and goal or conversion tracking setup. GA4 and Google Tag Manager are configured with consent mode, IP anonymization, event tracking, and conversion goals tied to your funnel. We connect Google Search Console, submit sitemaps, and set up basic uptime and performance monitoring—so your data is clean, compliant, and actionable from day one.
• 30‑day post‑launch support window for bug fixes, see Guarantees for details. If something in the theme does not behave as specified, we triage and patch it promptly. This window covers defects and regressions, not new features or content changes—peace of mind while your team settles in.

From there, we move into proactive website management to keep your site secure and fast, and to improve it month over month. Ready to see what your launch package looks like? Request a sample deliverables set or book a quick consult at 314-657-7421 or jc@stlcodescape.com.

Ongoing website management and iterative growth

Launch day is just the start. With an STL CodeScape retainer, your WordPress site stays healthy, secure, and steadily improving—while your team focuses on the business outcomes that matter.

• Proactive care and monitoring: Staging‑first core and plugin updates, security patches and hardening with least‑privilege roles and two‑factor guidance, automated offsite backups with point‑in‑time restores, round‑the‑clock uptime alerts, and ongoing tracking of Core Web Vitals with remediation when thresholds slip—so surprises don’t derail campaigns or cost you leads.
• Editorial and campaign support: On‑demand content edits, new pages and reusable landing pages, seasonal homepage refreshes, and campaign setup including UTM tagging, goal and event tracking, and CRM or email platform integrations for forms and lead capture. Send the brief, and we’ll turn it into a polished, on‑brand experience that converts.
• A clear growth cadence: Quarterly roadmap planning to prioritize high‑impact work, A/B tests and experiments to validate ideas, iterative UX refinements informed by analytics and heatmaps, accessibility tune‑ups, and scoped feature rollouts with release notes and training where needed—keeping momentum without guesswork.
• SLAs and reporting you can trust: Defined response and resolution times matched to your plan (critical issues triaged immediately), plus monthly reports focused on your KPIs such as leads or revenue, conversion rates, search visibility, Core Web Vitals pass rate, average load time, uptime, and crawl health—paired with clear next steps you can act on.

Whether you’re an in‑house marketing team or a creative agency, we slot into your workflow—Slack, Jira or Asana, Git, and your release calendar—so shipping becomes routine, not a fire drill. Want a dependable partner for the long haul? Explore our Website Management and Hosting, ask for a sample report or a quick site health check: jc@stlcodescape.com or 314-657-7421.

Built to partner: direct‑to‑business and white‑label for agencies

Whether you’re a growing business or a creative agency, we plug in where you need us and work like part of your team—so you get momentum without adding headcount. If you need to move quickly, we can spin up a pilot sprint to prove value fast.

Direct‑to‑business

• We collaborate with owners, marketing leaders, and in‑house teams to translate goals into technical requirements and a clear release plan—so everyone sees scope, timeline, and budget before we code.
• We define success up front—editor experience, brand consistency, Core Web Vitals targets, and conversion paths—and report on them after each sprint.
• Marketing moves fast, so we keep content and campaign requests flowing with a simple intake, clear priorities, and predictable deployment windows (rush options available when you need them).
• Want a quick read on feasibility or cost? Email jc@stlcodescape.com for a same‑day estimate window.

White‑label for agencies

• NDA first and discreet. We protect your client relationships and operate under your brand, including co‑branded or white‑labeled staging and documentation. Your client, your credit.
• We code from your Figma and design systems, join client calls as your dev team when needed, and mirror your QA and approval process—so everything feels native to your workflow.
• Repos can live under your organization with full code ownership, transparent estimates, timelines, and acceptance criteria. No lock‑in, just reliable delivery.
• Capacity crunch or a hot RFP? Ask about our 1–2 week kickoff availability.

How we work together

• Communication: Shared Slack or Microsoft Teams channels for quick collaboration, plus scheduled standups or weekly demos to keep momentum. Prefer email‑only or a different cadence? We adapt.
• Project management: Jira or Asana boards with clear scopes, priorities, and timelines. We can also work in your Basecamp, ClickUp, or Monday if that’s home base for your team.
• Code quality: Git‑based pull requests and reviews in GitHub, GitLab, or Bitbucket, with a documented checklist for accessibility, performance, and security.
• Environments: Staging and preview links for every release, database‑safe deployment protocols, automated backups, and rollbacks.
• QA and sign‑off: UAT checklists, release notes, and post‑launch monitoring so you know what shipped and what’s next.
• Documentation: Editor guides, component libraries, and handoff docs so your team can move confidently without guesswork.

Proof in practice: quick project vignettes

These snapshots show what custom WordPress work looks like when it’s done right—clean builds, measurable gains, less stress for your team. If you recognize your situation below, let’s talk about a quick assessment and roadmap.

Vignette 1 — From page‑builder template to a lean custom theme

• Goals: Eliminate bloat and plugin conflicts, stabilize Core Web Vitals on mobile, make content edits faster for a small in‑house team.
• What we did: Ran a full plugin and theme audit, replaced the page builder with a hand‑coded Gutenberg theme using theme.json, consolidated 11 plugins worth of functionality into core or theme features, implemented an image and CDN pipeline with WebP and responsive sizes, preloaded critical fonts, and added server and object caching with careful cache‑bypass rules for forms.
• Measured deltas we track:
  • Plugin count: 37 to 14, monthly update time 2.5 hours to 45 minutes.
  • Core Web Vitals on mobile, field data via Search Console: LCP 5.2s to 2.1s, INP 280 ms to 130 ms, CLS 0.22 to 0.02, Good URLs coverage rose from 58% to 96% within 30 days.
  • TTFB, monitoring: about 900 ms to about 360 ms.
  • Admin workflow: average edit to publish time for a basic page dropped from about 30 minutes to about 9 minutes, support tickets about page breaks after update went from 5 per month to 0 in the first 90 days.

If you’re stuck on a heavy page builder or fighting plugin conflicts, we’ll outline a lean migration plan and quick‑win performance fixes. Start with a no‑obligation audit: 314‑657‑7421 or jc@stlcodescape.com. Learn more about our performance optimization process.

Guarantees and ownership

You should never feel tied to a vendor or unsure about what you own. Here’s how we remove risk and keep you fully in control from day one:

• 30‑day bug‑fix window: For 30 days after launch, we fix any defects within the agreed scope at no charge—no surprises. Defects are items that don’t match approved designs/requirements or that break under normal use. We acknowledge issues within one business day. Critical, site‑breaking items are prioritized for same‑day or next‑day remediation.
• Clean code ownership: At launch you receive full repository access (GitHub or Bitbucket), including the theme, any custom plugins, build tools, and deployment scripts. You have perpetual rights to use, modify, and move the code to any vendor. Third‑party libraries remain under their original licenses, and we document them clearly. Want a quick repo tour before you commit? Just ask.
• No vendor lock‑in: We don’t use proprietary page builders or closed frameworks. Themes are built with the native WordPress block editor and theme.json. We rely on a minimal set of vetted plugins and provide a plugin inventory with reasons for use and recommended alternatives—so any competent WordPress developer can step in if you ever need them.
• Accessibility and standards baseline: We implement WCAG 2.1 AA fundamentals—semantic HTML, logical heading structure, labeled forms, visible focus states, ARIA landmarks where appropriate, and sufficient color contrast—then test keyboard navigation and common screen readers. Code follows WordPress Coding Standards and is compatible with the current major WordPress release and typically one prior.
• Updates and rollbacks you can trust: We document how core, plugins, and themes are updated, the staging‑first workflow, and who does what. Every release is versioned and backed up (files and database), with a step‑by‑step rollback procedure if anything misbehaves. On our management plans, we handle monthly updates and urgent security patches. If you self‑manage, we provide the same checklist and train your team.

FAQs

How long does a custom theme take?

Most brochure sites launch in 6 to 10 weeks from kickoff. Ecommerce and integration‑heavy builds typically run 10 to 16 weeks or more. Key timeline drivers are scope, number of templates and blocks, content readiness, third‑party integrations, and the speed of design and content approvals. We publish a milestone schedule at kickoff and keep approvals tight to maintain momentum. If you have a hard deadline, we can explore a phased MVP launch or add sprints to meet it—ask us for a tailored timeline. For more context, see our take on website timelines.

What determines cost?

Drivers include design complexity and animation, number of unique templates and custom blocks, ecommerce features such as catalog size, variations, subscriptions, shipping and tax rules, third‑party integrations like CRM, ERP, or marketing, content migration volume, accessibility targets such as WCAG, multilingual needs, and whether you want ongoing management after launch. We scope these transparently so you know where each dollar goes, with line‑item options you can phase in. Share your must‑haves and we’ll provide a clear, no‑surprises estimate.

Will my site stay compatible with future WordPress updates?

Yes. We build to WordPress core standards, including the block editor, theme.json, and custom post types and fields, keep the plugin footprint lean, and avoid hacks. Updates are tested in staging before going live. With our maintenance plans, we handle core and plugin updates, backups, uptime and performance monitoring, and safe rollbacks. Prefer to manage updates in‑house? We’ll provide a simple checklist so you can do it confidently. Need specialized help? Talk to our WordPress Specialists.

Do you include training and documentation?

Yes. Every build includes hands‑on editor training, a concise admin guide that covers your custom blocks and patterns and publishing workflows, and short video walkthroughs. We set roles and permissions to protect brand consistency. Post‑launch Q&A support is included, and we are available for ongoing optimization. Your team will be ready to publish on day one—and we can run refresher sessions for new team members anytime.

What hosting do you recommend, and do you handle migration?

We work with reputable managed WordPress hosts and recommend options based on traffic, performance needs, and budget. We set up staging, SSL, CDN and caching, and automated backups. Our team plans and executes the migration and DNS cutover for a smooth, low‑downtime launch, coordinating timing to protect SEO and analytics continuity. We’ll handle the heavy lifting so you don’t have to. Explore our Web Hosting Company services and Hosting Solutions.

Who owns the code? How are third‑party assets and fonts handled?

You own the custom theme, custom plugins, and front‑end code upon final payment. No vendor lock‑in. We provide Git repo access and deployment workflows. Any third‑party plugins, stock imagery, or fonts remain under their licenses. We document everything and can procure or transfer licenses to your accounts as needed, so ownership is clear.

Can you migrate us off Divi or Elementor or an old legacy theme?

Yes. We map and clean your content, rebuild it as performant blocks and patterns, remove shortcode cruft, preserve URL structure and SEO metadata, and implement 301 redirects where appropriate. The result is a leaner site, better Core Web Vitals, and a simpler editing experience. Ask for a quick audit and we’ll outline a step‑by‑step migration plan. See how we specialize in custom WordPress.

Do you support multilingual, better site search, headless, and analytics?

Yes. For multilingual we typically use WPML or Polylang with clear translation workflows. For search, we can enhance native search or integrate Relevanssi or Algolia—our AI Integrations also power semantic search and recommendations. When a decoupled stack makes sense, we can power a headless front end such as Next.js via REST or GraphQL. We set up GA4, Google Tag Manager, and Search Console at launch and can add consent management and event tracking—see our guide on analytics setup.
