What this site is
A service point is a small business with thin margins and a lot of handling. Most of the trouble comes from three places: commission that was never calculated properly, a cash float that is too small for the busy hours, and records that cannot answer a question three months later.
Each page here takes one of those and works it through with numbers. Nothing on this site is an offer, and no company pays for a mention.
Commission maths
Why a percentage quoted per transaction is not the number that ends up in your pocket.
Cash float
How much to keep at the counter, and what happens on the two days a month when that is not enough.
Records
The smallest set of notes that still answers a question from last quarter.
Who writes this
One person who spent four years behind a counter and now writes it down. Where a number is an estimate, it says so.
