About Patsch9 Accounting Bridge for WooCommer…
From the official readme · v2026.10.8Description
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.
Trademark notice: WooCommerce® is a trademark of Automattic Inc. Lexware® and Lexware Office are trademarks or product names of Haufe-Lexware GmbH & Co. KG. This is an independent third-party extension and is not produced, sponsored, or endorsed by Automattic or Haufe-Lexware.
Features
- Automatic or manual invoice creation from WooCommerce orders.
- Read-only reconciliation of historical WooCommerce orders with existing Lexware invoices using the order number in the invoice introduction plus gross-total verification.
- Exact email based Lexware customer matching.
- Queue-based processing with deduplication and locking.
- Action Scheduler integration with WP-Cron fallback.
- Credit notes based on the original Lexware invoice snapshot.
- Invoice download and WooCommerce My Account integration.
- WooCommerce email integration.
- Optional handling of rental deposit metadata without a hard dependency on a rental plugin.
- HPOS compatibility.
- Conservative handling of ambiguous write responses to reduce duplicate accounting documents.
Requirements
- WordPress 6.9 or newer.
- PHP 8.2 or newer.
- WooCommerce 10.9.4 or newer.
- A Lexware Office account with Public API access enabled.
- A valid Lexware API key.
Configuration
For improved secret handling, the Lexware API key can be stored outside the WordPress database in wp-config.php:
define( 'PATSACBR_LEXWARE_API_KEY', 'YOUR_API_KEY' );
The constant takes precedence over a key stored in WordPress options.
External Services
Lexware Office Public API
The Lexware Office Public API at https://api.lexware.io/v1/ is a core service required by this plugin. Depending on the action, data sent to Lexware may include customer names, billing and shipping addresses, email addresses, order items, prices, taxes, shipping or fee items, and order references. The API key is transmitted for authentication.

Frequently asked questions
Do I need a Lexware account?
Yes. An active Lexware Office account with Public API access is required.
What data is transferred?
The customer, order, line-item, price, tax, and reference data required to create or retrieve contacts and accounting documents is transferred to the Lexware Office Public API.
Is plugin data removed when the plugin is deleted?
Not by default. Full data cleanup on uninstall must be explicitly enabled in the plugin settings.
Which languages are supported?
English is the source language. A complete German (de_DE) translation is bundled, including customer emails and invoice text defaults for new installations. Existing custom invoice texts and saved email settings are preserved. Additional translations can be contributed at https://translate.wordpress.org/projects/wp-plugins/patsch9-accounting-bridge/.
