read
Returns one invoice as the invoice mask shows it: customer, positions with quantity, unit, net price and tax rate, totals, status and whether the E-Rechnung toggle is on. Linked payment reminders are listed oldest first, so your agent can see whether a customer was already chased. The totals are the numbers sevdesk calculated.
