Shopify to WooCommerce
Scope the store migration together with changes to the ordering journey. At GM Keramik, the brief was to leave a costly Shopify setup and focus on local pickup.
Custom WooCommerce plugins, checkout improvements and integrations. Built by Jonas Stenild on WordPress and PHP, with your store’s existing setup in mind.

Your store needs to fit what you sell and how you handle orders. Here are three types of project I can help with.

We establish how customers order, how products reach them and which systems need the order. The test plan follows the journey from product to order management.
A specific rule for products, shipping or data can live in a plugin. My published Product 404 Redirects demonstrates a focused feature: handling old product links.
GM Keramik: Shopify to WooCommerce and local pickup documents a platform move with a clear business purpose. Also explore my published WooCommerce extension Product 404 Redirects.
For your project we agree the scope, affected data, launch plan and responsibility for ongoing operation. Delivery includes the agreed configuration or code, relevant test results and handover. Hosting, licences and maintenance are part of the cost discussion.

Why WooCommerce
WooCommerce combines content and commerce on WordPress. Theme, extension and hosting choices affect both day-to-day operation and future development.
WordPress and WooCommerce offer a broad ecosystem of extensions and developers. We first assess whether an existing plugin covers the requirement.
Built on top of WordPress, WooCommerce inherits a massive plugin ecosystem, a mature theming layer, and a community of millions of developers. Integrations are virtually limitless.
Open-source at its core, WooCommerce gives you full control over every aspect of your store. Its hooks and filters architecture means any behavior can be extended or overridden with a custom plugin.
What I Build
Purpose-built extensions for your checkout, catalog, administration and everyday operations.

Integration with the agreed payment provider. We establish existing extensions, webhooks and refunds, then test relevant payment journeys in the provider’s test environment.
Custom shipping rate calculators with carrier API integrations, zone-based pricing, weight and dimension rules, real-time rate lookups, and label generation.
Custom product option builders, configurators, and personalization tools. Let customers build their own products with dynamic pricing, conditional logic, and visual previews.
Custom checkout fields, multi-step checkout flows, conditional field display, order validation rules, and post-purchase actions that streamline the buying experience.
Recurring payment handling, subscription lifecycle management, plan switching, prorated billing, renewal reminders, and customer self-service portals for subscription-based stores.
Stock tracking, warehouse integrations, low-stock alerts, bulk import/export, supplier management, and multi-location inventory sync plugins for complex fulfillment needs.
Connect WooCommerce to ERPs, CRMs, PIM systems, marketing platforms, and any external service using the WooCommerce REST API and custom endpoints with proper authentication.

Technology Stack
WooCommerce hooks, APIs and maintainable PHP connect your store to the rest of your business.
The backbone of WordPress and WooCommerce. 20+ years of PHP experience means clean, performant, and secure code following PSR standards and WordPress best practices.
Deep expertise in WordPress's action and filter system. Every plugin hooks into the right places - no core modifications, no fragile overrides, just clean extensibility.
Full command of WooCommerce's internal APIs - from product CRUD and order management to shipping zones, tax calculations, and the checkout pipeline.
Custom REST API endpoints, webhook integrations, and third-party service connections built on WordPress's REST API infrastructure with proper authentication and validation.
Modern JavaScript for interactive storefront features, AJAX-powered admin interfaces, and dynamic checkout enhancements. jQuery where WordPress expects it, vanilla JS where it shines.
Optimized database queries, custom tables where needed, proper use of WordPress's $wpdb abstraction, and efficient data handling for high-traffic WooCommerce stores.
Development Process
A practical process with a clear scope, compatibility checks and support after launch. Explore each step below.
SELECT A STEP TO READ MOREWe start by defining the exact problem the plugin needs to solve. I review your store setup, WooCommerce version, existing plugins, and business requirements to create a detailed technical specification.
I design the plugin architecture around WordPress coding standards and WooCommerce best practices. Hook strategy, database design, API contracts, and admin interface wireframes are all mapped out before a line of code is written.
Development with regular reviews of the agreed task. Affected functions are tested on staging with the agreed WordPress, WooCommerce and PHP versions. Checkout, permissions and failure cases are included where the change affects them.
Clean delivery with full documentation, installation instructions, and admin configuration guides. I provide ongoing maintenance, compatibility updates for new WooCommerce releases, and dedicated support.
