Advance Payments in Receivables
My client (Event planning industry) has requested that the sales invoice is issued once installments are fully paid: The client settles all payment installments (approx. 6) and once the payment is fully received, an official invoice is issued to the customer, bearing the date of the event.
Based on my research, this cannot be achieved using prepayments since the system only allows one prepayment per advance invoice.
How can I create an invoicing configuration where the official (tax) invoice is generated once all payments are settled by the customer?
