We use the installment payment terms feature on our customer invoices. We usually require 30% advanced deposit within 5 days from the invoice date and the balance to be paid 10 days prior to the expected delivery date. We usually do batch deliveries. For example, orders submitted from date x to date y would all be delivered on date z. This results in different advanced deposit due dates but the same final payment due date for a batch. Unfortunately, it does not seem possible to edit manually the installment due dates in the customer invoice itself. This forces us to create an installment payment term for every unique invoice date-final payment due date combination. We like the installments feature because it allows us to have multiple due dates in a customer invoice and age the split amount separately in the standard aging report. Is there any way to make this more sustainable without changing the business process? Or an alternative solution?

Probably just create a script to alter the invoice after creation to your business logic.

But the installment due dates are not editable in the invoice. The developer we talked to said that it's also not editable via script.

There is an

Override Installments

checkbox you can use that makes due date and amount editable in the UI. You can definitely change amounts via script, so I would be very surprised if the due date was different.

THAT IS AMAZING. THANK YOU SO MUCH. And I can see that checkbox in the Records Browser so hopefully it's really editable in SuiteScripts.
