Refunds are made from the sale itself: client file, Purchases tab.

  1. Open the sale and choose to refund it.
  2. Set the Issue date.
  3. If it was paid in installments, choose which payments to refund.
  4. Click Refund.

If the sale was already invoiced, the refund automatically generates a corrective invoice.

Important: an issued invoice can't simply be deleted. To cancel it, issue a corrective invoice.
