  • The starting row is fictional and is not merchant evidence. Replace it with your verified internal record. Blank fields remain unresolved.
  • Keep Yes, No, Not sure and Not applicable distinct. A reported answer is not an independent BlueFinch verification.
  • Record one bounded check or decision per row. Add evidence dates and use unknown rather than zero when a value is unavailable.
  • Do not enter card data, account credentials, customer information or private financial documents. Use internal reference codes.
  • Filled fields do not establish completion, compliance, profitability or a revenue opportunity. Verify the actual acceptance result.
  • Export deliberately to approved business storage. Browser edits are cleared on reload.

A busy bank account does not explain the month’s operating result. Customer receipts, supplier payments, loan movements, and owner draws can land in different accounting categories or periods. Get a consistent baseline before you call what’s left profit.

Read the operating-records question carefully

The Profit Leak Scanner asks if the business reconciles monthly revenue and expenses from the same period. Its guidance calls for one accounting basis and separation of items such as owner draws and loan principal from operating expenses. The tool doesn’t retrieve bank records or certify how items are classified. A Yes answer is the owner’s report. Not sure creates a task to review the records. Pick a representative month and keep the source references. Don’t pair current revenue with an older expense estimate just because both numbers are easy to find.

Keep the accounting basis consistent

The SBA explains the distinction between cash and accrual methods for recording transactions, and recommends maintaining sound bookkeeping. Work with your bookkeeper to choose the basis that fits your records and reporting needs. A sale completed in one month and paid for in another shows why timing matters. The Books tool supports enabled accounting workflows, but a connected view doesn’t automatically settle every classification question. Keep the definitions tied to the comparison. A change in accounting basis between two periods can create an apparent improvement or decline that is not a change in the underlying business operation.

Use an incomplete-month example

In a fictional example, an owner enters $50,000 in revenue and $38,000 in listed expenses, but leaves out insurance, payroll-related costs, and a supplier bill. That $12,000 remainder isn’t verified net profit. Missing expenses are unknown, not zero. The scanner shows a margin based on entered expenses only under its documented conditions: positive revenue, all current costs entered, and the user confirming the list is complete. Even then, it doesn’t verify the records independently. That completeness statement matters, but it isn’t an audit of the business.

Keep proposed savings outside the historical record

A historical baseline shows what happened in the period you chose, on the basis you chose. A replacement-cost scenario shows what might happen under stated assumptions. The Small Business Savings Audit separates current costs, proposed costs, and one-time change expenses. A blank proposal doesn’t mean a free replacement, and don’t count bundled bills twice. Don’t rewrite last month’s operating result with next month’s hoped-for savings. The SBA’s cost-benefit guidance supports comparing costs and benefits over a defined period. The actual bookkeeping record remains the source for the historical view. Keep the scenario clearly labeled when you share it.

Use the monthly-baseline worksheet

Record the month, accounting basis and source of the revenue figure. Is the expense list complete? Note any unresolved classifications for the bookkeeper. Use internal references, not account numbers or private documents. A useful result may be “baseline incomplete pending one supplier reconciliation,” which is more honest than a polished but unsupported margin. Keep the later proposal comparison in a separate record. The scanner doesn't save entries in browser storage or send them to BlueFinch. Export or print deliberately if needed, and review the included inputs and assumptions before sharing the file with anyone.

When the bookkeeper resolves a missing item, update the baseline with its source and date. Don’t just change the total. A later reader should be able to see why the remainder changed. Keep owner draws, financing movements, and operating expenses classified using the appropriate records and professional review. The worksheet helps you organize things. It doesn’t replace a reconciled ledger or financial statements.
