Your Uncommonly Amazing WordPress Tech Partner
Custom WordPress plugins, built and maintained by a team that has kept complex WordPress sites running for over a decade.
WordPress plugin development is the work of building custom functionality into WordPress when no off-the-shelf plugin does exactly what your site needs, whether that is a brand-new plugin, an extension to one you already run, or a fix for a plugin that broke after an update. MemberFix builds custom WordPress plugins and integrations for membership, course, and eCommerce sites, then maintains them so they keep working through WordPress, PHP, and third-party API changes. If you can describe the outcome you want, we can tell you whether a plugin is the right way to get it, and what it takes to build.
Most WordPress problems do not need a custom plugin. Part of our job is telling you when they do and when they don't, because a custom plugin you have to maintain forever is a liability if a $49 off-the-shelf plugin would have done the job.
When custom development genuinely is the right call, you want a team that writes plugins the way they should be written: using WordPress hooks and APIs instead of hacking core or a theme, following the WordPress coding standards, and building so the plugin survives the next update instead of breaking on it. That is the difference between a plugin that quietly does its job for years and one you are paying someone to firefight every quarter.
We have spent over a decade in the guts of membership, LMS, and eCommerce sites. We have written our own plugins to solve problems the market had not solved (our Magic Login Link plugin came out of exactly that), and we have untangled plenty of custom code other developers left behind. So we know what “maintainable” actually costs, and we build for it.
When your workflow needs functionality that no existing plugin provides, we build it as a proper standalone plugin: self-contained, update-safe, and documented so the next person can understand it.
Most of our work is extending what you already have, MemberPress, MemberMouse, LearnDash, WooCommerce, Paid Memberships Pro, Restrict Content Pro, Gravity Forms, so it does the specific thing your business needs. We build against each platform's own developer hooks, so your customization survives the plugin's updates.
A lot of “we need a plugin” turns out to be “we need these two systems to talk to each other.” We connect WordPress to CRMs, payment processors, email platforms, Airtable, Zapier, and custom APIs, so member data, payments, and access flow automatically instead of by hand.
Inherited a site with custom plugins nobody documented, or code that breaks on every WordPress update? We audit it, tell you honestly whether to fix or replace it, and then do the work.
Slow, insecure, or bloated plugin code costs you members. We profile what your plugins are actually doing and rewrite the parts that are hurting you.
We take full ownership of the outcome, not only the code. We scope the work with you before we write anything, so you know what it costs and what you are getting. We build in a staging environment and test before anything touches your live site. And we do not disappear after launch. A custom plugin is only worth building if it keeps working, so most of our development clients keep us on a Care Plan to maintain what we built.
A 20-minute call with a technical team member. We'll hear you out, give value where we can, and let you know what it takes to build.
It depends entirely on scope. A small extension to a plugin you already run is a very different project from a new plugin built from scratch. We scope every project up front and give you a fixed quote before any work starts, so there are no surprises. Tell us what you are trying to accomplish and we will tell you what it takes.
Often, no, and we will tell you so. If an existing plugin or a small configuration change solves your problem, that is what we will recommend, because a custom plugin is something you then have to maintain. We only build custom code when it is genuinely the best way to get the outcome you want.
Yes, and that is most of what we do. We build against each plugin's official developer hooks and APIs rather than editing its files, so your customization keeps working when the plugin updates. We work across the membership, LMS, and eCommerce stack: MemberPress, MemberMouse, LearnDash, WooCommerce, Paid Memberships Pro, Restrict Content Pro, Gravity Forms, and more.
Yes. We regularly inherit undocumented custom plugins and code that breaks on updates. We audit it, tell you honestly whether it is worth fixing or should be rebuilt, and then handle it.
That is exactly what we build to avoid. We use WordPress and platform APIs the way they are meant to be used and follow the WordPress coding standards, so your plugin survives updates. And because things change over years, most clients keep us on a Care Plan so we maintain what we built.
Tell us about your project using the form on this page. We will get on a call, understand what you actually need (and whether a custom plugin is the right answer), scope it, and give you a fixed quote before any work begins.
