Merit Aktiva and WooCommerce Integration

If every web shop order means creating an invoice in Merit Aktiva by hand, it costs time and mistakes creep in. A Merit Aktiva integration creates invoices, customers and, where needed, stock updates automatically when a WooCommerce order reaches the right status.

The result: your accountant sees correct sales invoices in Merit straight away, with the right VAT and payment methods, and you stop entering the same data twice.

What the work includes

• Sales invoices. a sales invoice is created in Merit Aktiva for each qualifying WooCommerce order through the Merit Aktiva API (API ID and key).
• Credit notes. refunds and cancelled orders produce a credit note linked to the original invoice.
• Customers. buyer details are matched against existing Merit customers and a new customer is created when needed.
• Products and articles. WooCommerce products are mapped to Merit articles by SKU or code, so invoice rows use the right items.
• Stock. if Merit is your source of truth for inventory, we sync stock levels to the shop.
• Payment methods and VAT. WooCommerce payment methods and tax rates are mapped to the matching Merit settings, including shipping and discounts.
• E-invoice. where needed, we set up e-invoice delivery to business customers.
• Test orders. we verify invoices with realistic scenarios (coupon, refund, foreign customer) before going live.
• Error log. failed transfers are logged so they can be reviewed and retried.

During the free review we decide whether a ready-made plugin fits or a custom integration is needed. That depends on your order logic, not on our preference.

The hours shown above are a typical baseline for a standard scope. Bespoke sync rules, such as multiple warehouses, price lists or B2B terms, are scoped after a free review.

What we need from you

• Merit Aktiva access and an API ID and key.
• When an invoice should be created from an order (paid, completed and so on).
• A summary of VAT rates, payment methods and articles from your accountant.
• WooCommerce admin access and, if possible, a staging site.

What is not included

• Setting up Merit itself and accounting decisions, which stay with your accountant.
• Complex multi-warehouse, price-list and B2B scenarios, which are estimated after the review.
• Integrations with other systems, see Directo and Erply.

Who this is for

It suits shops with enough orders that manual invoicing is a burden, and whose accounting runs in Merit Aktiva. If the shop itself is slow or needs other support, see also speed optimisation.
