How this tool works
Use a credit note to correct an amount on an earlier invoice. Enter a new document number and the original invoice number. Enter the credited lines as positive values; the tool applies the credit direction to the total.
Common questions
Should I enter negative amounts?
No. Enter line amounts as positive values. The credit note generator handles the credit direction.
How do I create a partial credit note?
Enter only the quantities and amounts you want to correct. If you made the invoice in this Rekenbox session, reuse its details and then adjust the lines. Choose a new number and reference the original invoice. The original remains unchanged.
