Custom WordPress plugins built to WordPress coding standards: integrations, custom post types, REST APIs, Gutenberg blocks and WooCommerce extensions.
WordPress Plugin Development
A well-coded plugin can add unique and exciting functionality to your WordPress website or blog. Whether you need just a few lines of code to make a small change to WordPress to better fit your needs or a major development project that transforms your WordPress into a complex application, Everycode is ready and able to build your tailored WordPress plugin–and to enable you to take full advantage of the nearly limitless possibilities plugins offer.
We can develop your WordPress plugin from scratch to meet your special requirements, or we can tweak, customize, or transform one of the tens of thousands of existing plugins so it becomes the perfect solution for your unique need.
Our team can also provide you with the e-commerce plugin solutions you need to drive your business, or specialized integration of plugins into other apps.
What’s included
We can build your WordPress plugins for a wide range of specialized functions, either by building from scratch or by creating unique plugin enhancements, modifying any of the already available WordPress plugins to satisfy your requirements.
Plugins from scratch
Object-oriented, namespaced code following WordPress Coding Standards and best practices.
API integrations
CRMs, ERPs, payment gateways, marketing tools and any REST or SOAP API you rely on.
WooCommerce extensions
Custom checkout logic, product types, shipping rules, subscriptions and reports.
Gutenberg blocks

How much does a custom WordPress plugin cost?
Small, focused plugins start from $900. Plugins with admin screens, third-party API integrations or WooCommerce logic are usually quoted between $3,000 and $15,000 depending on scope.
Who owns the plugin code?
You do. After full payment the code is yours, released under the GPL-compatible licence WordPress requires, with documentation and source in your repository.
Will the plugin survive WordPress updates?
Yes. We only use public hooks and APIs, never modify core or third-party files, and test against current WordPress and PHP versions. Our Care Plan can keep it maintained long-term.
Can you fix or extend a plugin someone else wrote?
Yes. We start with a code audit, report security and performance issues, then extend the plugin through hooks or refactor it where needed.
