WordPress plugin development.

When no existing plugin does what your business needs, we build one that does exactly that and nothing more. We also set up and configure the plugins worth keeping, so features work without slowing the site down.

Custom plugin code, written clean, tested before it ever reaches your site.

The problem & the fix

Fifty plugins, still missing the one you need.

The problem

Sites collect plugins the way drawers collect cables. Each one solves part of a problem, adds its own scripts and settings, and the one feature your business really needs still is not covered.

Our solution

We audit what you have, keep the few plugins that earn their place, and custom build the missing piece. One focused plugin usually replaces three general purpose ones.

Why choose GAP3

Why teams trust our plugin work.

Custom code is a commitment. We write it so it stays an asset, not a liability.

Safe with updates

Coded to WordPress standards, tested against new versions, and kept off the deprecated APIs.

Light on the site

A focused plugin loads only what it needs, unlike the multi purpose plugins it replaces.

Documented handover

You get the source, the docs, and the freedom to have anyone maintain it later.

Custom plugins fit when.

A workflow no existing plugin quite covers Two systems that need to talk to each other A plugin stack that has grown slow and fragile An abandoned plugin your site depends on A feature idea you want scoped honestly

FAQ

Plugin development questions, answered.

When a feature is core to how your business works and no existing plugin covers it cleanly. If an existing plugin does the job well, we will tell you to use it instead.

It tracks the complexity of the feature. A small workflow plugin is a modest fixed price; a booking system or deep integration costs more. The quote is fixed and itemized before we write a line.

Yes. We debug conflicts, patch abandoned plugins, and extend commercial plugins through their hooks so updates stay safe.

Done properly, the opposite. A focused plugin typically replaces heavier general purpose ones and loads only on the pages that use it.

Yes. Pricing rules, shipping logic, checkout fields, and integrations are among the most common WooCommerce plugin requests we build.

You do. Full source, documentation, and no licensing strings. Any developer can maintain it after us.

We code against stable WordPress APIs and offer a maintenance arrangement that tests the plugin against each major WordPress and PHP release.

Yes. CRMs, billing systems, inventory tools, and custom APIs. If it has an API, we can usually connect WordPress to it.

Yes. Plenty of plugin work involves internal business logic, and we are happy to sign an NDA before you share details.
