Please create a setting that would allow us to enter the 'amount' on an invoice and not the 'per item' amount. Reverse the math.
Example: I enter the quantity of 200 and the amount of $459, the system calculates the per item cost of $2.295.

If this was a toggle option:
A: enter quantity & per item cost, system calculates the total (current set up)
toggle to
B: enter quantity & total cost, system calculates the per item cost.
Currently we are having to manually calculate the per item cost on a calculator, then entering it so it correctly so it calculates the total we want. This is very time consuming when you are busy and doing a number of estimates.
Not every business works in widgets.
Thank you!
