Use expected paid units
Quantity should reflect the paid units you reasonably expect for this run, not an unsupported demand target. Compare several explicit scenarios when volume is uncertain.
Estimate one pre-order run without hiding the inputs.
Use this planning estimate before publishing a pre-order run. Enter your own price, quantity, ingredient, packaging, labour, payment-provider, OrderPay, and other run costs. No result is saved or sent to OrderPay.
Include every direct run cost
Enter ingredient and packaging costs per unit, labour hours and hourly cost, payment-provider fees, the applicable OrderPay fee for the run, and other costs that change with the run.
Read contribution carefully
The result is revenue less the entered direct run costs. It is not business profit, tax advice, a price recommendation, or a guarantee because rent, insurance, waste, tax, and other overhead may remain outside the estimate.
