Cash-flow analysis and financial evidence

Read financial records without confusing movement with income.

A bank account receives $30,000. It looks like revenue until the analyst sees that the money came from another account owned by the same business. Cash-flow underwriting is partly arithmetic and partly careful labeling.

Normalize before calculating

Classify inflows and outflows before computing a ratio. Internal transfers, loan proceeds, refunds, and customer revenue have different meanings. Repeated movement between accounts can inflate apparent activity without adding economic income.

Use stable transaction identifiers and a documented categorization process. Preserve raw descriptions for restricted review, but expose normalized categories downstream. Record confidence and allow correction. A merchant with unusual payment descriptions should not inherit a poor credit decision merely because a parser has never seen its industry. Validate categories against representative samples and financial records.

A bank feed contains movements of cash, not a ready-made income statement. Transfers between the same owner’s accounts can appear as new receipts. Borrowing can increase cash without increasing sales. A tax payment can make one month look unusually weak even when it reflects an obligation accumulated over several periods. Normalize these items with traceable rules and preserve the original transactions for review.

Missing coverage matters as much as classification. One connected account may exclude the account that pays wages or collects a large share of revenue. The analysis should state which accounts and periods it covers, how complete the data appears, and which conclusions depend on that coverage. A neat ratio calculated from an incomplete feed can be more misleading than an explicitly limited estimate.

Read the cash conversion cycle

A business can be profitable while cash is tied up in inventory or receivables. The cash conversion cycle connects inventory days, receivable days, and payable days. In a simplified model, inventory days plus receivable days minus payable days estimates the time cash is tied up.

For 40 inventory days, 30 receivable days, and 20 payable days, the cycle is 50 days. This is a teaching ratio, not a complete forecast. Seasonality, deposits, supplier terms, and uneven sales can change the practical need. Compare the cycle with the proposed financing term and actual cash ladder.

Stress the weak month

An annual average can hide months in which cash cannot cover obligations. Build monthly or weekly views appropriate to the business. Identify low periods, customer concentration, fixed costs, and delayed receipts. Use documented assumptions rather than a single unexplained stress percentage.

A seasonal seller may earn most revenue before holidays and pay suppliers months earlier. Financing that amortizes evenly can create pressure during the low season. Test the proposed schedule against that pattern. A stress case should show the path from changed assumptions to a cash shortfall so the decision can be challenged.

Consider a seasonal seller with strong annual sales and a cash trough before the holiday period. An annual average can imply comfortable debt service while the business cannot meet a payment in its weakest month. Build a simple time-based cash forecast using opening cash, expected receipts, essential payments, and debt service. Then change the assumptions that matter: delayed customer payments, slower stock turnover, or a large supplier deposit. The point is to locate the timing of a shortfall and the available response, not to make one precise forecast appear certain.

Reconcile cash and accounting views

Bank transactions, management accounts, tax records, and financial statements can describe different periods and bases. Reconcile the differences before treating disagreement as deception. Accrual revenue may precede receipt; a loan payment includes principal that is not an ordinary operating expense in an income statement.

Create a bridge between reported earnings and cash available under the underwriting definition. Label non-cash items, working-capital movement, and financing flows. Use consistent periods. A clean bridge does not prove the business is safe, but an unexplained bridge makes the capacity estimate difficult to trust.

Financial records reveal more than repayment capacity. They may expose health, family, location, or other sensitive patterns. Define permitted use, access, retention, and correction. A data connection does not mean every available field should become a model feature.

Track source coverage and outages. An empty feed can mean no activity, a disconnected account, or a provider error. Provide a clear path for customers to supply valid alternative evidence where the product permits it. Keep the distinction between data availability and creditworthiness visible to decision makers.
