Treating accounting as a filing activity
When books are only updated ahead of a deadline, they serve compliance but not decision-making. The cost is invisible: choices get made on instinct because the numbers are not current.
Mixing personal and business transactions
It is common in owner-managed businesses and it complicates everything downstream — reconciliation, reporting and tax positions. A clean separation from the start avoids repeated clean-up.
Letting reconciliations slip
Bank, debtor and creditor reconciliations are the early-warning system for accounting errors. Skipping them for a few months usually means the difference is discovered at year-end, when the trail has gone cold.
No documented process
If the accounting process lives only in one person's head, it leaves with them. A short written process for recording, approving and reconciling transactions protects continuity.
