What is actually different?
A bookkeeper does not just record transactions. They notice that a supplier has been billing you twice, that a customer has quietly stopped paying, that the numbers do not look like last year. That is judgement, and software is worse at it.
What software is better at is doing the same thing every day without getting bored, at a cost that does not rise when the volume does. Reconciliation, matching, filing and chasing are exactly the work that suits a machine and wastes a person.
The version that usually works is both: Bizzle keeps the books current and a human reviews rather than types. That costs far less than paying someone to do the data entry, and it keeps the part of the relationship that is actually worth paying for.
