Hi,
We are looking at using advance customer invoices. The way we would like it to work is as follows:
- Advance invoice issued upon customer order creation and release
- Following invoices are issued as per the regular process but the amount from the advance invoice is deducted (if advance invoice is 10% of the CO value, 10% is deducted from the amount of subsequent invoices).
Advance invoice creation is straightforward. However, we are not able to find a way for subsequent invoices to take into account the amount already paid.
Practical example: I can request advance payment (via issuance of advance invoice) of 10% of CO value. The rest will be invoiced after final delivery/completion of work. Assuming a CO of 1,000
- Advance invoice: 100
- Final invoice: 1,000 - 100
The amount that is deducted should appear on the invoice.
Thanks in advance (no pun intended...)
