Sourcing fee model calculator: percentage fee, built-in markup or flat plan

Enter one factory order and compare three ways of paying for sourcing help: a percentage fee with a minimum, a price with the margin built into the unit price, and an open-book flat monthly plan. Every figure is your own assumption; the tool only does the arithmetic.

How the numbers are calculated

What this tool does not do

ChinaPayCheck is not a freight forwarder, customs broker, bank, escrow service or law firm. The calculators run in your browser on the figures you enter; nothing is sent anywhere, and the results are arithmetic, not quotes or advice.

To check the company behind a quote before paying, send the PI and the payment instruction to Free Triage (USD 0). Ongoing sourcing runs on flat monthly workspace plans with no percentage sourcing fee.
