If you cancel a summary invoice, all normal invoices on it will be released. A summary invoice can only be cancelled until it has been adjusted payments. If payments have been adjusted to the summary invoice, you first need to cancel the adjustments to be able to cancel the summary invoice.

In case a summary invoice is cancelled, and a customer needs a document of it, a summary invoice with a status cancelled can be printed as a credit invoice and sent to the customer.

To do this, simply select Print Summary Invoice on the ribbon. The cancelled summary invoice is printed with the “Credit Invoice” text and negative amounts in the first page. Note that cancelling a summary invoice won’t cancel the normal invoices attached to the summary invoice.
