About this plugin
Patsch9 Accounting Bridge connects WooCommerce with the Lexware Office Public API. It can create and manage invoices and credit notes from WooCommerce orders, process synchronization jobs through a queue, and make invoice documents available in the customer account.
The plugin declares WooCommerce High-Performance Order Storage (HPOS) compatibility and uses WooCommerce order CRUD APIs for order data.
