the service order is the lowest level of invoice and the system will not generate an invoice for a partial order.
there is an option to mark payments on the order , it can be recorded on back-end & mobile.
it will not create a full invoice but will have a proper record in the database and the final invoice will only be on the sum that was not included in the payments and will have also a field for the payments that were collected.
Thanks Danny, I have tried it out and it does as you say. Although no separate invoice generated, the pre-payments are shown on the Resolve tab and the final invoice excludes those amounts.
I think we can use that, thank you
