Creating Cancellation Invoices Correctly: How to Reverse Invoices Properly

An invoice was sent incorrectly? A customer cancels an order? Then you need a cancellation invoice (also called a reversal invoice or credit note). Here's how to do it correctly.

When Do You Need a Cancellation Invoice?

A cancellation invoice is required when you need to correct or fully reverse an already issued invoice:

• Errors in the invoice (wrong amounts, wrong customer, wrong services)
• Order cancellation after invoice issuance
• Returns of goods already invoiced
• Price reductions after invoicing
• Duplicate invoices issued by mistake

Important: You cannot simply delete invoices! Legally, invoices must be archived and can only be corrected via cancellation invoices.

The Difference: Cancellation Invoice vs. Credit Note vs. Correction Invoice

Cancellation Invoice (Stornorechnung)

• Completely reverses an existing invoice
• All amounts are listed as negative
• Has its own invoice number

Credit Note (Gutschrift)

• Issued for new refunds (e.g., goodwill gestures)
• Not directly linked to an existing invoice
• Also has its own number

Correction Invoice (Korrekturrechnung)

• Corrects an existing invoice
• Often replaces cancellation invoice + new invoice
• References the original invoice

Required Information on a Cancellation Invoice

A cancellation invoice must contain the same mandatory information as a regular invoice:

1. Your complete company name and address
2. Customer's complete name and address
3. Your tax ID number or VAT ID
4. Date of the cancellation invoice
5. Unique invoice number (e.g., S-2025-001)
6. Reference to the original invoice (number and date)
7. All original items - but with negative amounts
8. Negative VAT amounts
9. Reason for cancellation

Step-by-Step: Creating a Cancellation Invoice

Step 1: Reference Original Invoice

Start with a clear reference:

Cancellation Invoice No. S-2025-001
Re: Invoice No. 2025-0042 dated March 15, 2025

Dear [Customer],

We are canceling the above invoice in full for the following reason:
[Reason for cancellation]

Step 2: List All Items as Negative

Step 3: Specify Payment Handling

Explain how the credit will be settled:

• Refund: "The credited amount will be refunded to your account within 14 days."
• Credit balance: "The credit will be applied to your next invoice."
• Offsetting: "The credit is offset against Invoice No. 2025-0043."

Tax Implications

VAT Treatment

Cancellation invoices are VAT-relevant:

1. The VAT originally shown is reversed
2. You can claim back the already paid input tax
3. The customer must adjust their input tax deduction

Accounting Entry

Cancellation Invoice:
  Debit: Revenue                   2,400.00 €
  Debit: VAT liability               456.00 €
  Credit: Accounts Receivable      2,856.00 €

Common Mistakes to Avoid

1. Wrong Invoice Number

❌ Using the original invoice number ✅ A cancellation invoice needs its own unique number

2. Missing Original Reference

❌ No reference to the original invoice ✅ Always state original invoice number and date

3. Incorrect Amounts

❌ Partial amounts or rounded figures ✅ Exact reversal of original amounts (as negative values)

4. Missing VAT

❌ Forgetting the VAT reversal ✅ VAT must also be shown as negative

5. No Reason Stated

❌ Cancellation without explanation ✅ Briefly explain the reason for cancellation

Partial Cancellation: How to Proceed

Sometimes you only need to partially cancel an invoice:

1. Full cancellation invoice for the original invoice
2. New invoice with the correct (partial) amount

This is cleaner than a partial cancellation invoice and causes fewer problems with accounting.
