How the numbers get checked

Numbers get worked through before they get published.

No rate cards
Carrier and processor prices change often, so pages explain how a charge is built and where to read the current schedule.
Sums run end to end
Each example goes from price to profit, and the calculator pages use the same formulas, written out in plain words.
Invented, and labeled
Prices, fees and weights in the guides are placeholders. A page that uses them says so, and you swap in your own.
