WordPress runs 40.7% of the web, and most of that is page-builder output: forty plugins, a theme nobody can update, and a page that takes six seconds to paint. Axiom builds custom themes, custom plugins, and headless WordPress front ends to the official coding standards, with a content model your editors can actually use.
Custom WordPress development and WordPress agency work for US businesses. You own the code, the repository, and the licences.
Custom themes and plugins built to the WordPress coding standards, by developers who read the codebase.
Elementor and WPBakery run on a large share of WordPress sites, and the markup they emit is why those sites are slow and impossible to restructure. We build custom themes with block patterns, so editors get defined layouts instead of free-floating boxes.
Every plugin is a dependency, an update, and a potential vulnerability. Patchstack found 96% of 2024's WordPress vulnerabilities in plugins. We replace stacks of overlapping plugins with a small amount of purpose-written code.
Caching hides a slow site, it does not fix one. We profile the actual queries, scripts, and images, cut what is unnecessary, and hold Core Web Vitals as a build requirement rather than a post-launch surprise.
If publishing a page risks breaking the layout, your team stops publishing. We model named content types and reusable blocks so the CMS constrains editors into good outcomes instead of handing them a blank canvas.
Unlicensed or unmaintained code is the most common route into a WordPress site. Part of any build is auditing what is installed, removing what is abandoned, and replacing what cannot be licensed properly.
You get the repository, the deployment pipeline, the documentation, and every licence in your own accounts. If you replace us, the next team inherits a codebase they can read.
The difference shows up in year two, when you need to change something the original theme never anticipated.
Themes and plugins follow the official WordPress PHP, CSS, and JavaScript standards, so any WordPress developer can pick the code up later.
Custom post types, taxonomies, and named fields designed around your content, rather than everything crammed into pages and a page builder.
We write the small amount of code that replaces a stack of overlapping plugins, which shrinks the update surface and the vulnerability surface with it.
Core Web Vitals targets are agreed in the scope document and checked at every review, not measured for the first time after launch.
Semantic headings, clean URLs, schema, and crawlable internal links are part of the theme, and Optima picks the site up from there.
Git from day one, a staging environment you can review in a browser, and deployments that can be rolled back — not FTP edits on production.
Scope varies by project. These are the components a custom WordPress build normally covers.
A theme written for your design and content model, using block patterns and template parts rather than a purchased theme bent into shape.
Purpose-written plugins for the functionality your business actually needs, replacing stacks of overlapping third-party plugins.
Custom post types, taxonomies, and named fields so editors fill in a defined structure instead of building pages from scratch.
WordPress as the editorial back end with a Next.js front end over the REST or GraphQL API, when you need app-grade front-end performance.
Store setup, custom checkout and shipping logic, and payment gateway integration where WooCommerce is the right commerce layer.
CRM, marketing automation, ERP, and payment systems wired in over documented APIs rather than a spreadsheet export.
Content, media, and URL structure moved with redirects mapped, so rankings and inbound links survive the change.
Repository access, written documentation, and a working session with your marketers, plus every licence in your own accounts.
Eight stages, each ending in something you can review in a browser. No phase closes on a status update alone.
Goals, editors, integrations, and an audit of the existing theme, plugins, and content.

Three ways to engage, depending on how defined the work is. Every engagement is quoted against an approved scope document.
$500 – $35,000
per project, fixed scope
A defined build with an agreed feature list, milestones, and a launch date. Priced per phase against the scope document.
Fits: new sites, redesigns, replatforms.
Discuss this model$250 – $10,000
per month, continuous
A standing block of development time for ongoing releases, maintenance, performance work, and support.
Fits: live sites that keep shipping.
Discuss this model$30 – $500
per hour
Time-boxed help where scope is still forming: consultation, audits, fixes, or a second pair of hands on your own build.
Fits: short engagements and unknowns.

Both produce a website. They differ in what happens the first time you need something the theme did not anticipate.
WordPress is not the problem. It powers 40.7% of the web because it is genuinely good at the thing it does. What breaks sites is how they get assembled.
A typical build starts with a purchased theme, then a page builder to make the theme do something it was not designed for, then a plugin for each missing feature. Each addition is reasonable on its own. Two years later the site carries dozens of dependencies nobody chose deliberately, a layout that only exists inside the builder's database, and a performance profile that no caching plugin can rescue.
Custom development front-loads the decisions instead. Model the content, write the theme, write the small amount of plugin code that replaces the stack, and the site stays cheap to change for years rather than expensive to touch after twelve months.
Custom theme development, custom plugin development, content modelling with post types and fields, integrations with your CRM or other systems, migration from an existing site with redirects mapped, and handover with documentation and training. Headless builds, where WordPress serves content to a Next.js front end, are available where front-end performance justifies the extra moving parts.
A purchased theme is designed for thousands of unrelated sites, so it ships with features you do not need and constraints you did not choose. It usually needs a page builder to fit your design, which is where the performance and maintainability problems start. A custom theme contains only your design and only your content model, which makes it faster to load and far cheaper to extend later.
We maintain sites that use them and we will work inside one when it is already there and replacing it is not the priority. We do not recommend building a new site on one. Elementor runs on a large share of WordPress installs, and the markup it produces is a common cause of the exact performance and restructuring problems clients come to us with.
Axiom projects run between $500 and $35,000 depending on scope, with monthly retainers between $250 and $10,000 for sites that keep shipping. A custom theme on an existing content structure sits at the lower end; a headless build with custom plugins and CRM integration sits at the upper end. Every project is quoted against an approved scope document rather than a page count.
Headless means WordPress stays the editorial back end while a separate front end, usually Next.js, renders the site using WordPress data over REST or GraphQL. It buys application-grade front-end performance and lets one content source feed multiple channels. It also adds a second codebase to maintain, so we only recommend it when the performance or multi-channel requirement is real.
Security is mostly a function of what is installed. Patchstack found 96% of 2024's WordPress vulnerabilities in plugins and only seven in core, so the biggest security decision in any build is how few plugins you can get away with. We audit what is installed, remove abandoned or unlicensed code, write the replacements, and harden the install. Ongoing patching is covered by a maintenance plan.
Yes. The repository, the deployment pipeline, the documentation, and every licence sit in your own accounts, and the code follows the official WordPress coding standards specifically so another developer can read it. If you move on from us, the next team inherits a working codebase rather than a puzzle.
Yes. Content, media, and structure are migrated, and every old URL gets an explicit redirect target so rankings and inbound links survive. We verify the redirect map and Search Console coverage after launch, because an un-redirected migration is the fastest way to lose organic traffic that took years to build.
Tell us where you want to rank. We'll send back a free audit and a clear plan to get you there.
