IT-Services Mertineit – Shop Connector for Papierkram

IT-Services Mertineit – Shop Connector for Papierkram connects WooCommerce with Papierkram and allows you to manually create draft invoices directly from WooCommerce orders.

The plugin deliberately keeps Papierkram as the leading system for invoice numbers, document status and invoice history while eliminating repetitive manual data entry.

Features

• Manual creation of draft invoices directly from WooCommerce orders
• Customers are found by email address and reused or automatically created if they do not already exist
• Product line items with original quantity, unit price and product number
• Coupons are transferred as separate negative line items
• Shipping costs are transferred as a separate line item
• Small-business mode according to German Section 19 UStG (0% VAT)
• Invoice number and document status synchronization
• Shipping status and optional tracking number management in WooCommerce
• Duplicate protection
• Order notes
• WooCommerce logging
• Connection test

Workflow

Create the draft invoice manually from the WooCommerce order → Review and finalize the invoice in Papierkram → Update the invoice number and status in WooCommerce.

Requirements

• WordPress
• WooCommerce
• Papierkram account (Plan M or L)
• API access enabled
• Papierkram API token

Product numbers are mandatory

Every product and every product variation requires its own product number.

For variable products, only the variation’s product number is used.

If at least one order item has no product number, the transfer is aborted. No customer and no invoice are created. The administrator receives an order note and a WooCommerce log entry explaining the problem.

Professional Edition

The Community Edition intentionally focuses on manual invoice creation.

Automatic synchronization, PDF download, PDF email attachments and additional automation features are available separately in the Professional Edition.

This plugin is an independent integration and is not affiliated with or endorsed by WooCommerce, Automattic Inc., Papierkram or odacer finanzsoftware GmbH.

External services

This plugin communicates directly with the Papierkram API (papierkram.de), operated by odacer finanzsoftware GmbH, Konrad-Adenauer-Ring 13, 65187 Wiesbaden, Germany.

When you manually transfer an order or perform a connection test, your web server sends requests directly to your own Papierkram account.

Depending on the order, the following information may be transferred:

• Customer name
• Company name
• Billing address
• Email address
• Phone number (if available)
• Order number
• Product names
• Product numbers
• Quantities
• Prices
• Coupons
• Shipping costs
• Tax information

The communication takes place server-to-server.

No customer data is transmitted from the visitor’s browser.

No data is sent to any third-party service other than Papierkram.
