Invoices, credit notes & cancellations
When Easy Invoices creates invoices automatically, how refunds become credit notes, and when a cancellation invoice is issued.
Automatic Invoice Generation
Easy Invoices monitors your Shopify orders in real-time via webhooks. As soon as an order is marked as paid, the app automatically creates a professional PDF invoice – without any manual intervention.
- Automatic detection of payments via Shopify webhooks
- Instant PDF generation with all order and customer data
- Sequential invoice numbers with configurable prefix (e.g., INV-2026-001)
- Atomic counters issue every number exactly once – gap-free and without duplicates
- Optional year prepending for annual numbering schemes
- Automatic email delivery of the invoice to the customer
- All invoices immediately visible and downloadable in the dashboard
Invoice number settings are locked after the first invoice is created to ensure GoBD-compliant gap-free numbering.
Credit Notes & Refunds
When refunds are issued in Shopify, Easy Invoices automatically creates a credit note. Each credit note is linked to the original invoice and has its own sequential numbering.
- Automatic creation for Shopify refunds (partial and full refunds)
- Separate sequential numbering for credit notes (e.g., CN-2026-001)
- Linked to the original invoice for complete traceability
- Tax rates and amounts are carried over from the original invoice, never re-estimated
- Automatic email delivery of the credit note to the customer
- Credit notes appear in the dashboard and all exports
Cancellation Invoices
For order cancellations, Easy Invoices automatically creates a cancellation invoice. It references the original invoice and carries the mandatory details of § 14 UStG.
- Automatic creation when orders are canceled in Shopify
- Reference to the original invoice per German tax law
- Separate sequential numbering for cancellation invoices
- Complete documentation of the cancellation reason
- Automatic email delivery to the customer
- Mandatory details and invoice reference per § 14 UStG
Cancellation invoices are only created for full order cancellations. For partial refunds, a credit note is generated instead.
