Custom WordPress plugin development for the feature you can’t find
Custom WordPress plugin development is for the moment you’ve tried five plugins and none of them fit. Maybe they do too much, slow the site down, or miss the one thing your business needs. I build a plugin that does exactly your job, follows WordPress coding standards, and comes with documentation so any developer can maintain it.

- Integrations
- Custom blocks
- WooCommerce extensions

Signs it’s time for a custom plugin
If two or more sound familiar, a small, focused plugin is often cheaper over time than paying for workarounds.

What custom WordPress plugin development looks like in practice
Pick a type of feature to see what a plugin like that usually involves.
Custom dashboards, approval workflows, bulk editing and reports, so your team stops working in spreadsheets.

From my work I’ve built a plugin ecosystem for Toastmasters District 127, so I know how to keep several custom plugins working well together.
Built like it’ll still be running in five years
A plugin runs inside your website. A badly built one can slow every page or open a security hole. So every plugin I build follows the same rules.
-
STANDARDS
WordPress coding standards
Consistent, readable code that other developers recognize.
-
SECURITY
Security first
Inputs sanitized, outputs escaped, nonces (one-time security tokens) on every action, and user permissions checked.
-
SPEED
Light on speed
Scripts and styles load only on the pages that need them. Good for speed and SEO.
-
UPDATES
Update-safe
No edits to WordPress core or other plugins, so updates don’t break anything.
-
DOCS
Documented
A README, inline comments and a short admin guide for your team.
-
GIT
Version-controlled
The code lives in a Git repository you own.
-
TESTS
Tested
On a staging site with your theme and plugins, before it touches the live site.
-
example
check_admin_referer( 'save_booking' ); if ( ! current_user_can( 'edit_posts' ) ) return; $email = sanitize_email( $_POST['email'] ); update_option( 'bs_notify', $email ); echo esc_html( $email );
My WordPress plugin development process
-
01
Scope.
A 20-minute call, then a written spec: what the plugin does, what it doesn’t, and how we’ll know it works.
-
02
Quote.
A fixed price and timeline, based on the spec. Typical plugins take 2–6 weeks.
-
03
Build.
Developed on staging, with progress you can test along the way.
-
04
Test & launch.
Checked against your live setup, then deployed with a rollback plan.
-
05
Support.
14 days of fixes included, then optional updates through a care plan.
What to expect from your WordPress plugin developer
You’ll work with me directly, from the first call to the last line of code. I’m a WordPress plugin developer and SEO consultant, so I think about how a feature affects speed and search, not just whether it works.

Agencies can also hire me for white-label plugin work. See my work →
How much does custom WordPress plugin development cost?
It depends on what the plugin does. A small admin tool or simple integration costs less than a multi-role workflow with external APIs. Small plugins start from $1,500, and complex ones usually run $4,000–$12,000. After a short scoping call, I write a spec and give you a fixed quote, so the price doesn’t move unless the scope does.
How long does WordPress plugin development take?
A focused plugin often takes 2–4 weeks from approved spec to launch. Larger tools with integrations or several user roles take longer. Most of the time goes into testing, not typing. I share a dated plan up front and a staging link, so you can test as the work progresses.
Why hire a freelance WordPress plugin developer instead of an agency?
You talk to the person writing the code, so nothing gets lost between account managers and developers. Decisions happen faster and costs stay lower. The trade-off is capacity: I take on a limited number of projects at once, which is why I confirm start dates in writing before we begin.
Will a custom plugin slow down my website?
It shouldn’t. I load scripts and styles only where they’re needed, keep database queries efficient and avoid running heavy tasks on page load. Often a custom plugin makes a site faster, because it replaces several general-purpose plugins that each load their own code on every page.
Who owns the plugin once it’s built?
You do. The code is delivered in a Git repository under your account, with documentation. You’re free to have any developer maintain or extend it. I don’t lock code behind licenses or my own servers, unless we’ve agreed on a commercial plugin model in writing.
Can you fix or extend a plugin someone else built?
Yes, if the code is accessible. I’ll review it first and tell you whether it’s worth extending or safer to rebuild. For third-party plugins, I extend them through their hooks rather than editing their files, so your changes survive updates.
let’s scope it
Have a feature in mind? Let’s scope your custom WordPress plugin development.
Tell me what you need the site to do. In 20 minutes, I’ll tell you whether a custom plugin makes sense, what it would involve, and a realistic price range. If an existing plugin will do the job, I’ll tell you that too.
