How can I receive a 50% advance payment from a client and deduct it from deliveries, as they will pay 50% of the total order and receive it in installments, paying the remaining value of each installment separately?
Create customer account then in the receipts, receive the payment and then in the accounts, choose “accounts receivable” and the name of that specific client, just auto for the invoice.
When you make deliveries, just create a sales invoice. The amounts will just offset.
In addition, you can go back to the earlier receipts and apply the amount to a specific invoice.
