Cash‑Flow Financing

Basics

Cash‑flow underwriting is an alternative way for lenders to determine borrowers’ creditworthiness. This method involves a lender reviewing a borrower’s current and historical bank account data to evaluate their ability and willingness to repay a loan.

By relying on real‑time income and expense information instead of credit scores alone, cash‑flow underwriting can unlock access to capital, increase underwriting efficiency, and better align lending decisions with borrowers’ present financial realities.

Benefits

The benefits of cash‑flow underwriting are especially important for small business loans. Often perceived as higher risk, these loans require more manual underwriting and extensive borrower interaction, which are factors that increase operational costs.

Lenders can instead access bank transaction information to streamline data collection and make decisions faster. For small businesses that lack assets or lengthy credit histories — often those owned by minorities, women, and immigrants — cash‑flow underwriting allows lenders to base credit decisions on current financial performance rather than historical proxies. This can improve access to critical capital that small businesses need to sustain and grow their businesses.

CDFIs that more widely adopt cash‑flow underwriting would be following an approach long used by the financial technology industry. Fintech lenders often use bank‑account data to make rapid underwriting decisions. (This is the case even though the resulting products, such as merchant cash advances, can carry high costs and unfavorable terms.)

Some CDFIs have used cash‑flow underwriting but it’s not widespread. That’s because CDFIs need the necessary data, expertise, funding, and technical infrastructure to implement this method.  

Background

Consumers and small business owners financed by traditional lenders typically meet minimum credit score, collateral, and financial history requirements. Yet an estimated 45 million to 60 million American adults have little to no credit history. And roughly one‑third of adults with credit scores can only qualify for the least favorable lending terms.

Cash‑flow underwriting can help more people get much-needed financing at competitive rates. Lenders can gain insight into a borrower’s credit history through bank transaction data. These data provide a recent and relevant picture of financial health that goes beyond a credit score.

This can work better for borrowers with negative credit events, which persist in credit scores for years, even when financial conditions have improved. Cash-flow underwriting is well-suited for borrowers with weaker credit profiles who can demonstrate the ability to repay loans using other metrics.

Evidence of Success

Research suggests that cash‑flow underwriting can be an effective tool for predicting repayment risk. Studies evaluating fintech lenders found that cash‑flow variables and scores were as predictive of loan performance as traditional credit metrics. Research showed that combining cash‑flow data with conventional credit information produced the strongest predictive results. Importantly, borrowers with insufficient credit scores but strong cash flow had low default rates. This shows that cash‑flow data can capture repayment factors missed by credit scores. Future research can explore how well these results translate to CDFIs, which serve distinct borrowers and operate under different constraints.

Potential Challenges

There are barriers that hinder broader adoption of cash‑flow underwriting within the CDFI sector. Organizations that conduct cash‑flow underwriting must securely access, categorize, and interpret bank transaction data, often through third‑party aggregators. Many CDFIs lack the staffing, funding, or technical expertise to implement, integrate, and manage these systems or tools. It’s even more complicated and time-consuming to apply cash-flow underwriting to borrowers who mix personal and business transactions. Borrowers also need assurance that cash-flow underwriting protects their data and privacy.

Bottom Line

Overall, cash‑flow underwriting is a feasible and promising method used within and outside the CDFI industry to assess borrower creditworthiness. The increasing availability of open‑banking technologies has lowered barriers to accessing transaction‑level data, and several CDFIs have successfully piloted cash‑flow underwriting models. Use of the technique could expand with additional funding for technology and capacity building. More research on the default risk of CDFI borrowers could propel even greater adoption of this innovative financing method.
