Who this checklist is for

Anyone selling online who does their own books and would rather spend an hour and a half a month than a fortnight in January reconstructing a year.

Sellers doing their own bookkeeping

The order matters as much as the items. You cannot judge a margin until the fees are recorded, and you cannot record the fees until the payouts are reconciled. The checklist puts them in the only sequence that works.

Anyone whose payouts never quite match

The first section is eight items on reconciling gross charges to bank deposits, with a short diagnostic list for the month it will not tie.

Sellers approaching the VAT threshold

One item every month: the rolling twelve-month total against £90,000. It is the check people skip, and the one that costs most when they do.

FACTS

A routine you can actually keep

Each section carries a time estimate and they add up to ninety minutes. If a section overruns badly, that tells you something specific is wrong with how the numbers are being captured.
