Build a new plugin from scratch
You describe the feature. We design the data model, write the PHP, wire the admin screens, and hand you the source. Hooks and filters only. No core hacks.
Services
Custom WordPress plugins, built right.
You have a problem that only a custom plugin solves. We turn it into clean PHP, ship it on staging, and hand it over with the source code. We know what good looks like. We built TrueCommander.

FixedScope, fixed quote
Six kinds of plugin work. Pick whichever one matches your problem.
Most engagements start with a single feature and grow from there. We scope tight, ship fast, and don't pad the invoice.
Modify or extend an existing plugin
Your current plugin is 80% of the way there. We add the missing 20% through a companion plugin so updates don't wipe your customizations.
WooCommerce extensions
Custom checkout flows, payment gateway integrations, subscription rules, product configurators, shipping logic. We treat WooCommerce as a platform, not a black box.
Third-party API integrations
Connect WordPress to your CRM, billing system, AI provider, or internal API. Auth, retries, error states, admin UI. The integration that doesn't break at 3am.
Performance audit and optimization
An existing plugin is slow or fighting your stack. We profile it, find the real bottleneck, and fix it. No "install another cache plugin" advice.
Architecture consultation
Before you write a line of code, we'll tell you what the plugin should look like, where the seams are, and which design decisions will hurt you in two years.
Five steps. No surprises.
Same flow on a $1,000 micro-plugin and a $15,000 multi-module build. The depth changes. The structure doesn't.
Discovery call
You walk us through the problem. Not the feature you think you want, the problem behind it. We come back with three questions you didn't think to ask.
Scope and fixed quote
A written scope, an itemized quote, and a delivery date. Fixed price for the scope. If we underestimate, that's our problem, not yours.
Build in staging
We build on a staging copy of your site so you can watch the plugin take shape. Weekly check-ins. You can stop us any time the work veers off the scope.
Review and iterate
Two rounds of revision included. We sit through your QA list with you. Anything outside the original scope gets a written change order so you always know what you're paying for.
Handover and 30-day bug fix
Source code, README, and a short Loom walking through the architecture. Any bug we shipped, we fix free for 30 days. After that, optional maintenance starts at $99 a month.
Code we'd be willing to put our own name on.
Every project ships with the basics that working WordPress code requires. Not extras. Not "premium tier." The defaults.
- WordPress.org coding standards.
The same lint rules wp.org would enforce on a public submission.
- Translation-ready.
Every user-facing string wrapped in
__(), with a generated POT file in/languages. - Hooks and filters, never core hacks.
Your WordPress core stays untouched. Updates won't wipe your customizations.
- Tested in staging before delivery.
Conflict-tested against the top 20 plugins in your install. Every release tagged in git.
- Source code is yours.
Full git history at handover. You own the repo. We don't license the code back to you.
- 30-day post-launch bug fix.
Anything we missed, we fix free for 30 days. No hourly meter, no fine print.
The stack we ship in.
The honest list, not a partner-logo wall. If something you use isn't here, ask. The answer is usually "yes, but tell us more first."

Frequently asked questions.
How much will it cost?+
Most projects land in the $1,000 to $10,000 range. A simple single-feature plugin starts under $1,000. A multi-screen WooCommerce extension with API integrations typically sits between $5,000 and $15,000. We quote a fixed price for the agreed scope. If we underestimate, we eat the difference.
How long will it take?+
Small plugins ship in 1 to 2 weeks. Mid-sized work is 3 to 6 weeks. Anything larger gets broken into release milestones so you have working software at the end of each one, not at the end of the whole project.
Will you modify WordPress core or theme files?+
No. Everything goes through hooks, filters, and the proper WordPress APIs. Your core stays vanilla, your theme stays yours, and the next WordPress update won't break our work.
Does it work on multisite?+
If you ask for it. Multisite support adds some scope (network admin screens, per-site settings, network-activated vs site-activated behavior). Tell us upfront and we'll quote it in. Bolting it on after the fact is more expensive than building for it from day one.
Is the plugin translation-ready?+
Yes, by default. Every user-facing string is wrapped in WordPress's i18n functions (
__(), _e(), _n()) with a unique text domain. We ship a generated POT file in /languages. Translators can take it from there with Loco Translate or Poedit.Do I get the source code?+
Yes. Full source, full git history, written in clean PHP your team can read and maintain. We don't license code back to you, and we don't keep a copy in a private "vault" you have to pay to access. Your code is your code.
Can I talk directly to the developer?+
You will. We're a small team. The person who writes your plugin is the same person who joins the discovery call, replies to your questions, and walks you through the handover. No account manager middle layer.
What happens if I find a bug after handover?+
If we shipped a bug, we fix it free for 30 days from handover. Email us. We'll have a patched build out within 2 business days. After 30 days, ongoing support starts at $99/month (priority email, bug fixes, WordPress and dependency compatibility updates).
Why custom WordPress plugin development, and when off-the-shelf is the better answer.
When custom is the right call
The cheapest plugin is the one that already exists. If the WordPress repository has a battle-tested plugin that does 90% of what you need, install it, configure it, and move on. Don't pay anyone to rewrite it. But "almost" rarely scales. The first time a half-fitting plugin runs into your real-world workflow, the support tickets start. Custom WordPress plugin development is for the cases where the gap between what's available and what your business actually needs is wide enough to cost real money to bridge with workarounds.
What a good custom plugin looks like
It does one thing your business needs, well. It's written so a developer who's never seen it before can read the code and understand what's happening in twenty minutes. It uses WordPress's own APIs the way the WordPress core team intended them to be used. It ships with documentation, with tests where they matter, and with a changelog. It doesn't try to do everything. A good custom plugin makes the next custom plugin easier to write, not harder.
How TruePlugins fits in
We're a small team that ships our own commercial WordPress plugin (TrueCommander, with 91 commands across 10 modules) and takes on custom plugin development work for a handful of clients at a time. Same standards, same code review process, same approach to scope and quoting. We don't chase volume. We pick projects where we can do work we'd be willing to put our name on.
Tell us about your plugin.
We'll come back within 24 business hours with questions and a rough budget range. No sales pressure. If we're the wrong fit, we'll tell you upfront and point you at someone better.
