Custom WordPress plugins: A/B tests, CRM integrations, forms and team tools
- WordPress
- PHP
Our usual stack. We bring in other tools when the task or the project calls for it.
When off-the-shelf plugins don’t fit, slow things down or conflict with each other, it’s simpler to build your own — exactly for the task and with no extra code.
We build plugins that solve specific business problems: from form-to-CRM integrations to A/B tests and internal team tools.
What we do
- Form and website integrations with your CRM
- A/B tests that work with caching and CDNs
- Team tools: bug reports, reporting, moderation
- Custom content types, fields and editor blocks
- Support and updates for new WordPress versions
What a custom plugin fixes
Dozens of plugins, and half of them overlap
We audit what's actually used, what conflicts and what loads on every page. The features you need go into one plugin; the rest is switched off after testing.
Form leads land in the CRM with empty fields
We integrate with your CRM's API: field mapping, UTM tags and a submission log. If the CRM is down, the lead is retried instead of lost.
The A/B test shows everyone the same variant because of caching
We split visitors at the CDN or via a cookie before the cache responds, then send results to your analytics. The test works on cached pages too.
Editors lack fields, so they hand-code layouts in the text
We add custom post types, fields and Gutenberg blocks for your content: product card, event, job opening. Editors fill in a form instead of writing HTML.
The team compiles reports and bug reports by hand
We build tools right in the admin: a bug report form with a screenshot and browser data, report exports, a moderation queue.

Your own plugin, no bloat
Built for the task
We write only what the job needs — no settings screens with a hundred options slowing down the admin.No conflicts
We check compatibility with your theme, plugins and caching before anything touches the live site.WordPress coding standards
The code follows WordPress conventions, so it survives core updates and any developer can read it.Staging first
We build and test on a staging copy and deploy to production only once everything checks out.
When a custom plugin pays off
A good fit if
- Off-the-shelf plugins slow the site down or clash with each other
- You need an integration with a CRM or internal system nobody has built yet
- The logic is specific to your business and won't be in the plugin directory
- The site drives sales and you don't want to depend on someone else's updates
Not a fit if
- A popular plugin does the job with some setup — buy the license and we'll handle the setup
- Your WordPress site is outdated and needs a rebuild — look at headless WordPress
- You need a complex service with accounts and roles — that's a web application
How we work
- 01
Task and site review
2–3 daysWe look at your theme, installed plugins and hosting so the new plugin doesn’t clash with what already works.
You get A spec and a list of compatibility risks - 02
Architecture and settings
1–5 daysWe plan the hooks, data storage and an admin settings page so your team can run the plugin without a developer.
You get A data schema and a prototype of the settings page - 03
Development
1–3 weeksWe write the plugin to WordPress standards: safe queries, translations, hooks for extension. We connect your CRM or external APIs.
You get The plugin on a copy of your site, ready for review - 04
Testing on a site copy
2–5 daysWe test on a staging copy with your theme and plugins, on current versions of WordPress and PHP.
You get A test report and a fixed build - 05
Installation
1–2 daysWe install the plugin on your live site and hand over the source code with docs. Bugs are fixed under a 3-month warranty.
You get A working plugin on your site, a code repository and setup docs

- Examples: existing plugins that almost fit
A call and a look at your site

Plugins slowing
your site down?
Describe the task and we’ll build a plugin exactly for it, with no extra code, tested on staging before it touches your live site.
If an existing one fits, we’ll use it. A custom plugin makes sense when existing ones don’t solve the task, are too heavy or need workarounds.
From $2,500. The total depends on the plugin logic, the number of CRM and third-party integrations, how much needs to be configurable in the admin and how many sites and PHP versions we test it on. We send an exact estimate after a call.
Yes, we maintain compatibility with new WordPress and PHP versions.
Yes, the plugin is yours to install on any of your sites.
We follow WordPress standards: capability checks, nonce-protected forms, escaped output.
