Hi @Daniel_JZH , please note that Percentage is not mandatory when creating an Advance Invoice for a Customer Order. You can either enter the Advance Amount (Invoice Net Amount) or Percentage.
If you enter the Advance Amount, system will automatically calculate the percentage. And If you enter Percentage, system will automatically calculate the Amount.
Yes, when the invoice is created, you cannot find the percentage value in the invoice. It is because there is no use of printing the advance percentage in the invoice. Only the advance amount will matter.
Percentage option is there for you to enter the advance amount that you are expecting from your customer, as a percentage of the order value (e.g. you expect 20% advance amount from your customer before processing the order).
