Why Clean Books Matter
The SBA estimates that29% of small-business loan rejectionsstem from sloppy financials (SBA Lending Survey 2024). A tidy ledger also slashes audit risk—IRS exam rate for businesses with proper documentation is 0.5%, versus 2.1% for those missing receipts (IRS Data Book 2023).

- Capture receipts immediately with a scan app (IRS Pub 583 endorses electronic copies).
Weekly
- Reconcile bank and credit-card feeds.
- Review unpaid bills and schedule payments.
- Chase aged receivables > 15 days.
Monthly
- Close the books by the 10th business day.
