Hello, Have any of you customized the invoicing process of Charge-based billing in Netsuite Projects? We are looking for a feature where we could change the quantity of service/billing items that we are invoicing based on the Milestone Rule. So for example, if we create a Milestone where we have attached a Project Task "bathroom demolition" and mark it as completed, instead of one we want to invoice 5 times the price of the item and the quantity would be five. Now with the Milestone Rule, we can only invoice with a quantity of one. It is locked so that we cannot even manually change the quantity when we click on invoice from invoice billable customers section. So do you have any ideas how could we add a quantity field or otherwise change the quantity on Milestone Rule/on the Invoice?
