What is included

Everything a WordPress Plugin Development engagement covers

Custom plugin development

A plugin built for your exact workflow — booking logic, pricing rules, approvals, integrations, admin tools — with settings your team can manage.

API & third-party integrations

Connect WordPress to your CRM, ERP, payment provider, shipping carrier or SaaS tool through clean, tested integrations.

Plugin fixes & refactoring

Inherited a plugin nobody understands? We audit, fix, refactor and document it so it stops being a risk.

Plugins to sell

Planning a commercial plugin? We build to marketplace review standards, with licensing, updates and documentation handled.

Gutenberg blocks

Custom blocks and block patterns that give editors real controls instead of shortcodes and custom fields.

Security & compatibility

Nonces, capability checks, escaping and sanitisation everywhere; tested against current and previous WordPress and PHP versions.

Why it matters

Why WordPress plugin development from WPExperts is different

  • 120+ plugins published and reviewed on official marketplaces
  • A senior team that has led plugin development for years, not a freelancer learning on your project
  • Every plugin follows WordPress coding standards and passes Plugin Check
  • Compatible with WooCommerce HPOS, block editor and the latest PHP
  • Documented, versioned and yours to keep
  • Optional retained support for updates and new features
Official WooCommerce Marketplace developers · 10+ years of experience

Most agencies have built a plugin or two. Our WordPress experts have shipped more than 120 of them to the official WooCommerce Marketplace and Envato — including B2B for WooCommerce, Role Based Pricing for WooCommerce and Google reCaptcha for WooCommerce — where every release is reviewed line by line before it goes live.

That is the standard we bring to your custom plugin: secure, documented, coding-standards compliant, and engineered to keep working through core, WooCommerce and PHP upgrades.

Custom plugin or existing plugin? Our WordPress experts tell you straight

The right answer is often "configure what exists" — and we will say so. When a custom plugin is the right call, it is because your requirement is specific, the existing options are bloated, or you need something you can rely on for years. We scope it in writing, build it on staging with weekly demos and hand it over with docs and tests.

Plugins we work with every week

WooCommerce, LearnDash, MemberPress, BuddyBoss, WPML, Gravity Forms, Advanced Custom Fields, Google Site Kit and the WordPress REST API. If your stack is on that list, we have probably already solved your problem once.

How we work

From brief to launch in four steps

Discovery

A short call or written brief. We map the real requirement, not the assumed one.

Written plan & estimate

Scope, milestones, fixed price and the risks we see — before anything is built.

Build in the open

Staging access, weekly demos and coding-standards compliant PHP you can read.

Launch & support

Deployment, monitoring and a warranty window. Then optional retained support.

FAQ

Questions before you get in touch

How long does a custom plugin take?

Small utilities take days. Integrations and workflow plugins typically take two to four weeks. Commercial plugins with licensing and updates take longer — we scope every one in writing first.

Will the plugin break when WordPress updates?

It is built on documented hooks and APIs, not core hacks, and tested against the current and previous WordPress and WooCommerce releases. A warranty window after delivery covers any compatibility issue.

Can you build a plugin we can sell?

Yes — that is our background. We know what WooCommerce.com and WordPress.org review teams look for and build to pass first time.

Do you take over plugins built by other developers?

Frequently. We start with an audit so you know exactly what you have inherited, then fix, refactor or rebuild depending on what is cheapest long-term.

Need a plugin built by people who publish plugins for a living?

Send a short brief. You will get a written plan, fixed estimate and realistic timeline — usually within one business day.
