our business process requires us to bill the customer in installments, I’ve read other post have done it via payment entry against single invoice, but for our case we have to issue invoice for each installments, please see below example
We issue the quotation to the customer totaling $1000
After customer purchase order we invoice the customer for 40% of $1000 which is $400
After we deliver the goods to customer, we invoice the customer for 40% which is $400
Then after the installation is complete we invoice the customer for the final 20% which is $200
So as you can see it’s important for us to create each invoice based on the percentage of the total amount, how do we achieve this with ERPnext?
