What to track
You do not need every possible metric. Start with the records that answer four questions: what came in, what went out, what is still owed, and what is left.
- Sales and revenue: invoices issued, payments received, refunds, and credits.
- Expenses: direct delivery costs and operating costs, recorded with a receipt or reference.
- Cash position: what is available in business bank and payment accounts.
- Receivables: invoices unpaid, due dates, and follow-up status.
- Tax reserve: an estimate set aside for tax obligations.
- Owner draws: money taken out of the business, kept separate from expenses.
Use one system as the source of truth. A spreadsheet can be enough for a small business. If you use accounting software, keep the same discipline rather than duplicating records in several places.
Use a small set of categories
Too many categories make the monthly review slow. Too few make it hard to see what is driving profit. Start with a short list and add detail only when it changes a decision.
| Group | Examples |
|---|---|
| Revenue | Service sales, product sales, project income |
| Cost of goods sold | Materials, direct contractor cost, payment fees tied to sales |
| Operating expenses | Software, rent, insurance, admin support |
| Marketing | Advertising, content production, event costs |
| Other | Bank fees, one-off professional costs, small equipment |
| Owner draws | Transfers to the owner, not a business expense |
If your accountant requires a different structure, follow their chart of accounts. Consistency matters more than copying an example.
A weekly and monthly routine
Weekly: 20 minutes
- Record new sales and invoices.
- Enter receipts and match business transactions.
- Check overdue invoices and send a short follow-up where needed.
- Review the cash balance and upcoming obligations.
Monthly: 30 to 60 minutes
- Close the month and make sure the period is complete.
- Reconcile bank and payment accounts.
- Review revenue, COGS, operating costs, and net profit.
- Update receivables and the tax reserve.
- Compare the month with the previous month and the same month last year if available.
- Write one action for the next month.
Cash is not profit
A business can show a profit and still run short of cash. An invoice counts as revenue when it is earned, but the money may arrive weeks later. A loan payment or equipment purchase may affect cash without being a current operating expense.
- Profit measures whether the business earned more than it spent in the period.
- Cash flow measures the timing of money in and out.
- Receivables are sales already earned but not yet collected.
- Payables are bills you owe but have not paid yet.
Review both. A profitable month with a growing receivables balance may need a collection action before it becomes a cash problem.
A monthly review example
Revenue: $48,000
COGS: $18,000
Gross profit: $30,000 (62.5%)
Operating, marketing, and other expenses: $18,000
Net profit before tax: $12,000 (25%)
Cash at month end: $21,000
Receivables due: $9,500
Decision: Follow up on the two largest overdue invoices before approving a new marketing spend.
The numbers are illustrative. The point is the connection between the report and a decision. A review that produces no action is just a ritual.

Common mistakes
- Keeping the only copy in email. Use a consistent folder or accounting system.
- Mixing personal and business transactions. Open a separate business account where possible.
- Recording owner draws as expenses. Keep them separate from operating costs.
- Ignoring small recurring costs. Subscriptions add up and are easy to forget.
- Using revenue as the only success metric. Margin and cash matter too.
- Leaving reconciliation until tax season. A monthly close is much easier to fix than a year of missing records.
- Assuming spreadsheets replace professional advice. Use qualified help for tax and accounting decisions.
Tracking checklist
- Business and personal money are kept separate.
- Every sale and expense has a reference or receipt.
- COGS and operating expenses are categorised consistently.
- Receivables are reviewed every week.
- Tax reserve and owner draws are recorded separately.
- Bank and payment accounts are reconciled at month end.
- The review ends with one written action.
