A little reading to begin with
A SAMPLE FROM CHAPTER ONEBegin by defining what one unit means. It could be one completed unreturned item sale, one order containing several items or a clearly bounded service package. Those units are different. A cost per order cannot be subtracted from each item without deciding how the order relates to the number of items in the comparison.
For the main fictional model, one unit is one completed unreturned item sale at a stated revenue amount of 30. All figures use one unspecified currency. The model initially contains no taxes, discount, refund or additional customer shipping charge. Those exclusions make the first calculation inspectable rather than establish how any actual sale must be treated.
Revenue and the bank deposit may differ. A payment route can deduct a charge before remitting money, and a deposit may combine several events. If you start from a net receipt, then subtract an already withheld charge again, you may double count it. Define whether the exercise starts with stated sales revenue or a net payout.
Keep physical units and money units consistent. A bundle sold for 30 is not necessarily a 30 sale for each component. A charge per transaction may apply once to the order while a packing item changes with each shipment. Ask how the amount is triggered before allocating it. The purpose is a comparable unit definition, not selecting a platform, changing invoice treatment or determining a tax base. A calculation cannot be more complete than the scope of the unit it describes.
