Five 15-minute habits for clean books.

Messy books are rarely caused by big mistakes. They’re caused by small ones, unattended, for months. These five habits are how owners who do their own books keep them clean, each one takes about fifteen minutes.

1 · Categorize weekly, not "eventually"

Once a week, open your bookkeeping software and clear the uncategorized transactions while you still remember what they were. Fifteen transactions from this week take ten minutes. Four hundred from last quarter take a weekend, and a lot of guessing, and guessed books are wrong books.

2 · Capture the receipt at the moment

Photograph it when you pay, bookkeeping apps and client portals file it against the transaction automatically. The bank feed proves you spent $214; only the receipt proves what it was, which is what your CPA, and any dispute, will need.

3 · One card per purpose

Business purchases on the business card, personal on personal, no exceptions on lazy days. This single habit does more for clean books than any software. (Tangled already? Here’s how to unwind it.)

4 · Reconcile monthly, actually reconcile

Once a month, match your books against the bank statement until the balances agree to the penny. Reconciliation is how you catch duplicates, missed transactions, bank errors, and fraudulent charges while they’re days old instead of months. If the numbers won’t tie out, that’s a signal worth fifteen more minutes.

5 · Keep a question list, don’t guess

Weird transaction? Unsure how to categorize that lunch? Write it on a running list instead of inventing a category. A pile of guesses becomes a P&L nobody trusts; a list of questions gets resolved in one short conversation with a bookkeeper or CPA, including the free first one with us.
