Correct erroneous invoices by first issuing a credit note (correction or cancellation invoice) for the erroneous invoice and then creating a new invoice.
- Go to the
Invoices tab in the side navigation. - Right-click the erroneous
Invoice and select "Create credit note". - If there are multiple invoices, click on
Create rebooking invoice. All items from the existing invoices are summarised in the rebooking invoice. - A
Spreadsheet with a new invoice number and the status "in progress" will open. - Select a suitable template by clicking on
Select text template (in the toolbar on the left). - A cancellation invoice will open with the address, the ordered items and an invoice number, but no date.
- To send the invoice as an email attachment, click on
Send document as PDF attachment by email. - When prompted, choose between making a Customer print with invoice date or an undated Proof copy.
- An
email cover letter will open, with the invoice attached in a PDF format. - If a Cover letter has already been preset for the spreadsheet template, this cover letter will also appear. If not, select a cover letter template or enter a custom text.
Save the email for sending later or 
Send it directly.- Change the status of the cancellation invoice and the original invoice to, e.g. "rejected" depending on your company specifications.
