If required, a payment demand can also be printed from a summary invoice. However, adding a reminder fee or delay interest is not possible without customizing the summary invoice template. A payment demand of a summary invoice can be printed at any time, regardless of the due dates of the summary invoice or the normal invoices attached to it. It can be printed to PDF, printer or as an email attachment.

To avoid sending by accident a payment demand of an invoice belonging to a summary invoice, the software informs if a payment demand is being created for an invoice which belongs to an open summary invoice.  A similar warning is displayed when a payment demand is being printed for multiple invoices of which some are on a summary invoice. However, the software does not inform which of the selected invoices belong to a summary invoice.
