Custom WordPress plugin development services
Custom WordPress plugin development services: update-safe code, admin settings, REST endpoints and WooCommerce hooks. Written scope, you own the plugin.
You searched the plugin directory and nothing fits, or three plugins fit badly and fight each other. A custom plugin does exactly one job, ships only the code that job needs, and survives WordPress updates because it was written against the platform’s own hooks and not by editing someone else’s files.
When a custom plugin makes sense
- A feature of your business process has no equivalent in the plugin directory.
- You run several plugins to approximate one behaviour, and they slow the site or conflict.
- You need WordPress to talk to an outside system: a CRM, an ERP, a payment provider, a booking tool.
- You sell a product that is itself a plugin.
- An existing plugin is abandoned and your site depends on it.
When an off-the-shelf plugin does the job with a few settings, use it. We tell you that in discovery, before you pay for code.
What we deliver
- The plugin. Installable ZIP and the source repository, structured to WordPress coding standards.
- Admin screens. A settings page and any record management your staff need, built with WordPress’s own admin patterns.
- REST endpoints and hooks. Custom endpoints when another system must call in, and filters and actions so your theme or other plugins can extend it.
- WooCommerce integration. Custom fields, pricing or checkout logic, order hooks and exports, when your store needs them.
- Documentation. Install notes, settings reference and a changelog.
What to send us first
- A description of the workflow, or screenshots of the current workaround.
- The plugins you use today for the same job.
- Sample data, if the plugin will import or export records.
- Your WordPress and PHP versions, and where the site is hosted.
- Any outside system the plugin must talk to.
How it stays safe and upgradable
| Practice | Why it matters |
|---|---|
| Nonces and capability checks on every action | Only the right users can trigger changes |
| Input sanitised, output escaped | Closes the common injection routes |
| Prepared database queries | No string-built SQL |
| Own tables only when needed | Custom post types and options are easier to migrate |
| Clean uninstall | Removing the plugin leaves nothing behind unless you want it kept |
| Tested on supported WordPress and PHP versions | Version support is written into the scope |
We do not edit core files or third-party plugin files. If a plugin needs changing, we extend it through hooks, so its updates still install.
How the work runs
- Brief. What the plugin must do, where it runs, what it connects to.
- Written scope and estimate. Behaviours, edge cases, supported versions, milestones and a USD estimate.
- Build in increments. Each increment is installed on a staging copy of your site, with a recorded demo.
- Launch. Installed on production with a rollback plan.
- Handover. The repository and documentation are yours. Fixes and later features continue as agreed.
Beyond the plugin
If the project is a whole site or theme, see WordPress development. If WordPress is only one piece of a larger system, the overview at custom software development shows what else we build. When the plugin’s real job is to connect systems, read API development and integration.
Frequently asked questions
What does custom WordPress plugin development cost?
It depends on scope: features, integrations, admin screens and compatibility needs. After a short discovery call you get a written estimate in USD. There is no price list, because plugins of the same name vary widely.
Can you modify an existing plugin?
We avoid editing it directly, because your changes disappear at the next update. We build an add-on that hooks into it. If the plugin is abandoned, we can fork it, and say so in the scope.
Will the plugin break when WordPress updates?
Any code can. We build against stable WordPress APIs, state the supported versions in the scope and test against them. Update checks after major releases can be added as maintenance.
Can you build a plugin for the WordPress.org directory?
We can prepare one to the directory’s guidelines. Acceptance is decided by the directory’s review team, so we cannot promise a listing.
Who owns the plugin code?
You do. The repository and documentation are handed over. NDA on request.
Do you work across time zones?
Yes. Our team works in GMT+7 and communicates asynchronously: written updates and recorded demos.
