Is it possible to set up direct manufacturing cost on quantity base?

Dear Experts,

I would like to ask if it is possible to get direct manufacturing cost based on output quantity, not hourly rate.

In our company, although we manage labor working hours, but at the end of the day (also the end of the batch order), we make payment immediately based on the number of products the labor finished.


I tried to set the actual price for quantity category and set price of run time category to 0, but it did not work as expected.

Could you kindly give me some advice for my case?

Thank you!
