Set up bookkeeping you'll actually keep
Most bookkeeping advice fails because it's built for accountants, not for a tired owner at 8pm on a Thursday. This is the minimum viable system: a real bank account, a capture habit, a weekly 20-minute close, and the documents you must keep — sized for businesses of one to ten people.

One account to rule them all
Step zero, before any software: a dedicated business bank account. Every business dollar enters and exits through it. Personal money stays out — and 'the company owes me $84 for stamps' is fine, but it needs a paper trail (see our separate lesson on separating accounts).
Commingled books cost real money at tax time (disallowed deductions, hours reconstructing history) and worse in an audit or an LLC liability dispute. The account is the cheapest insurance you'll ever open — usually free.
Capture everything, once, cheaply
You cannot bookkeep what you didn't capture. Two habits cover 95% of small businesses: (1) every business purchase goes on the business card — never cash; (2) receipts get photographed or scanned the same day (a shoebox in your truck is not a system). Most banks and card apps now attach images for you.
- Business card for everything business — the statement is your backup record.
- Same-day receipt capture: phone photo into your bookkeeping app, or a monthly email-to-inbox ritual.
- Mileage: a log app or the IRS standard rate per mile with dates and purpose.
The 20-minute weekly close
Bookkeeping collapses from a dreaded weekend into a routine when it's weekly and bounded. Same day every week, 20 minutes:
- Reconcile the bank and card feeds (match, categorize — most tools guess 80% right).
- Enter or verify the week's invoices: who owes, who paid.
- File digital receipts to where your tool keeps them.
- Glance at the dashboard your tool builds from this data — that's the payoff.
Don't chase perfection — chase weekly. Sixteen perfect monthly books you never finish lose to fifty rough weekly closes you actually did.
What to keep, and for how long
| Record | Keep for | Why |
|---|---|---|
| Tax returns | 7 years | The audit window is generally 3–6; 7 is the safe standard |
| Receipts & invoices | 7 years | They substantiate the numbers on the return |
| Bank & card statements | 7 years | Backup for everything |
| Payroll records | 7 years after the employee leaves | Federal and state requirement |
| Contracts & legal | Life of the contract + 7 | Disputes can surface years later |
Storage can be digital — scans and photos are accepted — but must be organized and retrievable. 'Somewhere in my email' is neither.
When to hire a professional
DIY bookkeeping is right at the start. Hire a bookkeeper when reconciling takes you over an hour a week or you stop doing it; hire a CPA when your taxes involve anything beyond a simple schedule C — payroll, inventory, multi-state sales, an LLC election. The pro's fee is usually less than the deductions and penalties they recover.
Frequently asked questions
Do I need accounting software, or is a spreadsheet fine?
A spreadsheet works up to roughly 20 transactions a month. Past that, a simple cloud tool (bank feeds, receipt capture, categorization) repays its monthly cost in your time alone — and gives your CPA clean books instead of a shoebox.
What's the difference between bookkeeping and accounting?
Bookkeeping is the recording — the weekly habit described here. Accounting is the interpretation and the filings — what a CPA does with your books quarterly and annually. You do the first (or a $200/mo bookkeeper does), a professional handles the second.
Can I do this on my phone?
Mostly yes: capture receipts, categorize transactions, send invoices. Reserve the monthly reconciliation and filing for a desk screen once a week — tiny screens invite tiny mistakes.
