What’s the best way to add several items to a specific invoice with a specific number?
I have two options - Generate a new invoice and Add an item to an existing invoice. With “Generate new invoice”, it’s clear - I have a form with invoice number, item’s names, payment terms etc.
But with “add an item to an existing invoice”, I’m struggling to figure out how to add items to an invoice with a specific number, keeping the payment terms the same.
What sorts of relations/formulas should I add?
