The paperwork around the books is not bookkeeping, but it is what makes bookkeeping possible — and it is usually the part still sitting in the owner's inbox.
Receipts scattered across an inbox, a phone camera roll and a glovebox. Subscriptions nobody has reviewed in two years. A year-end request from the accountant that takes a weekend to answer.
Documents where they should be, questions answerable without a search, and the accountant's annual request handled in an afternoon rather than a weekend.
Coding a transaction takes seconds. Working out what an unlabelled payment was for eleven months later can take an hour and still end in a guess.
Missing bills mean GST claimed late or not at all, and figures that cannot be substantiated if they are ever questioned.
Your accountant charges for time. Time spent hunting documents is time not spent on anything useful to you.
An unreviewed subscription list is one of the few places a small business finds money without doing anything harder than looking.
