WooCommerce developer
A WooCommerce store that handles the load, not just one that works.
Custom extensions, HPOS migration, payment, B2B, ERP connectors. WooCommerce treated as a real e-commerce system, by the team behind 42 published WooCommerce extensions.
WooCommerce launches in a few clicks, but a store that really sells ends up with needs that off-the-shelf extensions handle poorly: a particular pricing calculation, a connector to your ERP, a B2B checkout, thousands of orders to process without slowing down the admin. We build custom WooCommerce extensions, compatible with HPOS and the block-based checkout, with the same rigour as the 42 WooCommerce extensions in our catalogue.
What a WooCommerce developer does for you
Custom extensions
Pricing rules, extra fields, delivery slots, quotes that convert into orders, configurable products, loyalty programmes. Our method is described in detail on the custom WooCommerce extension development page.
HPOS migration and block-based checkout
High-Performance Order Storage (HPOS) and the block-based checkout change the way extensions read orders and add fields. We audit your extensions, fix or replace the ones that fall short, then migrate on a copy before the switchover.
Payment and B2B
Deposits, deferred payment for business customers, customer-specific pricing, quote requests, pro forma invoices. See also our WooCommerce subscriptions and WooCommerce plugins for B2B pages.
ERP and accounting connectors
Orders, stock, prices, customers and invoices synced with your ERP, your accounting software or your logistics provider. Dedicated pages: Sage WooCommerce connector and Cegid WooCommerce connector.
Performance on large catalogues
Queries on product metadata, an overflowing Action Scheduler queue, extensions that load their scripts on every page: we measure, then fix in order of impact. See the WooCommerce Core Web Vitals optimisation page.
Our WooCommerce development rules
- WooCommerce CRUD API rather than direct queries on the tables, to stay HPOS-compatible.
- Long-running jobs in the background with Action Scheduler, never during a page load.
- Security by default: nonces, capabilities, escaping, prepared statements.
- Tests as a guest and as a logged-in customer, with several VAT rates and payment methods.
- Testing on a copy of your store before going live.
What affects the price
Our quotes start at €1,500 and stay fixed once the scope is approved:
| Factor | Impact |
|---|---|
| Cart and checkout | Changing the cart calculation, taxes or payment requires more test cases. |
| External integration | A modern API connects quickly; a file-based exchange requires more checks. |
| Volume | Tens of thousands of products or orders require batch processing. |
| Existing setup | Competing extensions covering the same feature add compatibility work. |
Real examples
- WooCommerce quote management with PDF, email delivery and Stripe payment.
- WooCommerce accounting export: FEC, Sage 100, EBP, Pennylane and other formats.
- Axonaut connector to sync customers and invoices.
- WooCommerce headless kit for a decoupled front end.
- WooCommerce server-side tracking, client and server.

Frequently asked questions
How much does a WooCommerce developer cost?
We work on a fixed-price basis, from €1,500 for an extension or a defined project. You receive a fixed quote within 24h of the scoping call.
Are your extensions HPOS-compatible?
Yes, by default, and with the block-based checkout too. We also help existing stores migrate to HPOS: extension audit, migration on a copy, then switchover.
Can you connect WooCommerce to my ERP?
Yes, as long as the tool exposes an API or a structured export. Exchanges run through scheduled tasks and are logged so they can be replayed. See our Sage and Cegid WooCommerce connector pages.
Do you handle subscriptions?
Yes, with WooCommerce Subscriptions or with a dedicated Stripe integration when the business logic requires it. See our WooCommerce subscriptions page.
My store is slow. Where do I start?
With measurement: the slowest queries, the Action Scheduler queue, page weight, extensions that load their scripts everywhere. We deliver a prioritised fix plan before any work begins.
Do I own the code?
Yes. Full source code, documentation and 12 months of WordPress, WooCommerce and PHP compatibility updates.
How long does an extension take?
Two to four weeks for most extensions; a connector or payment logic can take longer. The timeline is written into the quote.
