Cash Flow Underwriting

Cash Flow & Affordability for Merchant Cash Advance

Cash-flow underwriting decides an advance by how much cash actually moves through the business’s account — deposits, balances, and existing obligations — not by credit score alone. Affordability is the output.

Definition

What cash-flow underwriting is

Traditional underwriting leans on credit history. Cash-flow underwriting looks at the operating reality: how much money comes in, how steadily, and how much is already going out. For merchant cash advance — where repayment is a percentage of receipts collected frequently — the merchant’s actual deposit flow is the most reliable predictor of whether a deal performs.

Inputs

The inputs that matter

Revenue and deposits — total inflow and how many deposits per month (consistency matters as much as size).
Average and daily balances — the cushion the account carries day to day.
Negative-balance days and NSF events — signs the account is already stretched.
Existing debits, including other advances — what’s already being collected (see stacking detection).
Trend across months — whether the picture is improving or deteriorating over three to four statements.

The Math

Calculating affordability

Affordability combines the extracted cash flow with the specific deal terms — the requested advance (how much the merchant wants), the factor rate (what determines the total payback amount), and the holdback (the percentage of receipts collected toward repayment). The question affordability answers is whether the holdback, applied to the merchant’s actual receipts, can service the payback without starving the business — especially once any existing advances are counted. A deal that looks fine on revenue alone can fail this test once holdback and existing positions are stacked against daily balances.

Trends

Why multi-month trend analysis matters

One strong month can mask a declining trend; one weak month can understate a healthy business. Aggregating three to four months smooths the noise and shows direction — rising revenue and stable balances support a deal, while climbing NSFs and thinning balances argue against it even if the average looks acceptable. MCA Verify aggregates the statements on a lead and surfaces the trend so the decision reflects trajectory, not a single snapshot. It’s built on AI bank statement analysis and is part of automated MCA underwriting.

FAQ

Frequently asked questions

What is cash-flow underwriting?

Cash-flow underwriting evaluates a borrower based on the money moving through their bank account — deposits, balances, and existing obligations — rather than primarily on credit score. It is the standard approach for merchant cash advance, which is repaid from receipts.

How is MCA affordability calculated?

By combining the merchant’s extracted cash flow (deposits, balances, NSFs, existing debits) with the deal’s terms — requested advance, factor rate, and holdback — to determine whether the holdback applied to actual receipts can service the payback without overextending the business.

What is holdback in a merchant cash advance?

Holdback is the percentage of a merchant’s receipts collected toward repaying the advance. It is central to affordability because it determines how much of the business’s incoming cash is diverted to repayment.

Why use multiple months of statements?

A single month can mislead. Reviewing three to four months reveals the trend — whether revenue, balances, and NSF activity are improving or deteriorating — which matters more than any one month’s figures.
