Custom WordPress plugins

A feature that doesn't exist yet, or an integration without a plugin? I build WordPress plugins exactly the way you need them, from a simple integration to a complete solution.

Connecting an online store to another system, something unique for your site, or extending an existing plugin: I'm happy to think along.

You work directly with Fred Klopper, founder of Miix: 25+ years of web development, eight of them at Laposta. More about Fred

Tell me about your project
custom.php
// connect your store to any system
add_action( 'woocommerce_thankyou', 'sync_order' );

function sync_order( $id ) {
  $order = wc_get_order( $id );
  JouwApi::push( $order->get_data() );
}

How we work together

  1. Intake

    We talk about what the plugin should do, which systems it connects and what you expect.

  2. Quote and planning

    You get a clear quote with features, lead time and price. Once agreed we plan the work, with milestones for larger projects.

  3. Development

    I build to WordPress best practices. On larger projects you see the progress along the way.

  4. Testing and feedback

    The plugin is tested thoroughly on a test environment. You test along and give feedback before it goes live.

  5. Delivery

    With installation instructions, a user manual and technical documentation for developers.

  6. Support

    Three months of bug fixes and small changes. After that, ongoing support is available.
