WooCommerce plugin development.

Every store eventually needs something the extension marketplace does not sell. We build custom WooCommerce plugins for pricing rules, delivery workflows, and integrations, coded lean so the store stays fast.

Your exact business rule, turned into a clean custom extension.

The problem & the fix

Ten extensions doing eighty percent of the job.

The problem

Stores bend their business to fit their extensions: pricing rules approximated with three stacked plugins, delivery quirks handled manually, and the billing software updated by hand every evening.

Our solution

One custom extension built around your exact rule replaces the workarounds. It does the whole job, loads only where needed, and your evening spreadsheet ritual retires.

Describe the workaround you are living with. We will tell you what replacing it takes.

FAQ

Extension questions, answered.

When a business rule matters and no extension expresses it: a pricing structure, a delivery constraint, an integration. If a good existing extension covers it, we will point you to it instead.

Yes. Custom fields, conditional logic, validation, and post-order actions are all standard requests, built through official hooks so updates stay safe.

Yes. If it has an API or even a file-based exchange, we can sync orders, stock, and invoices automatically in both directions.

Built properly against stable hooks, no. We also offer maintenance that tests your extension against each major WooCommerce release before your store updates.

Yes. We audit the code first, tell you honestly what shape it is in, and either maintain, refactor, or replace it.

A marketplace extension serves a thousand stores approximately. A custom one serves yours exactly, with no subscription, no unused settings, and no weight from features you never enabled.

A fixed quote based on the spec we write together. Simple rule plugins are modest; deep integrations cost more. Many replace enough monthly subscriptions to pay for themselves.

You do, entirely: source code, documentation, and the right to have anyone work on it.

Yes. We also build commercial extensions to WooCommerce.com and CodeCanyon standards for teams productizing an idea.
