In Xboss, it's not possible to modify an invoice that has been validated and sent to the customer. If a mistake was made on a validated invoice, the legal way to handle that is to refund the invoice, reconcile it with the original invoice to close them and create a new invoice.

Modifying a validated invoice 

If you need to modify an existing invoice, use the Refund Invoice button on the invoice. In the refund method field, select "Modify: create a refund, reconcile, and create a new draft invoice".

Xboss will automatically:

  • Create a refund for your invoice

  • Reconcile the refund invoice with the original invoice (marking both as Paid)

  • Create a new draft invoice you can modify

Then, you can modify the draft invoice and validate it once it's correct.

Cancelling an invoice

If you need to cancel an existing invoice, use the Refund Invoice button on the invoice. In the refund method field, select "Cancel: create a refund and reconcile".

Xboss will automatically:

  • Create a refund for your invoice

  • Reconcile the refund invoice with the original invoice (marking both as Paid)

Nothing else needs to be done. You can send the refund by regular mail or email to your customer, if you already sent the original invoice.

Refunding part of an invoice

If you need to refund an existing invoice partially, use the Refund Invoice button on the invoice. In the refund method field, select "Create a draft refund".

Xboss will automatically create a draft refund. You may modify the refund (example: remove the lines you do not want to refund) and validate it. Then, send the refund by regular mail or email to your customer.
