What cash flow metrics do lenders look at for accounting firm working capital loans?

When you apply for a working capital loan, lenders extend the credit based primarily on your firm's ability to generate enough cash flow to repay it, so the underwriting centers on a handful of cash flow ratios. The metric they scrutinize most is the debt service coverage ratio (DSCR) — your operating income divided by total annual debt payments. Beyond DSCR, expect them to review debt-to-revenue, debt-to-equity, accounts receivable quality, and the recurring revenue that makes accounting practices attractive borrowers.

For a CPA firm, the good news is that lenders evaluating working capital lines look at cash flow and short-term assets rather than hard collateral — these lines are typically secured by accounts receivable, exactly the asset a billing-heavy practice holds.

Debt service coverage ratio (DSCR)

DSCR is the single most important metric in cash flow underwriting. It is calculated by dividing net operating income by total debt service. A DSCR above 1.0 means your firm generates enough income to cover its debt; lenders want a cushion above that. Most banks want to see a DSCR of at least 1.25, which signals you have working capital plus a safety margin rather than just scraping by. SBA 7(a) lenders also generally require a minimum DSCR of 1.25x — a firm with $1 million in net operating income and $750,000 in annual debt service would carry a 1.33x DSCR. Traditional banks may prefer 1.35 or higher, while alternative lenders may approve at 1.10 or slightly below.

Some lenders compute the numerator as EBITDA divided by total annual principal and interest payments instead of net operating income; either way, Commerce Bank advises the DSCR should be no lower than 1.2.

Leverage and revenue ratios

Lenders also size your overall debt load. According to Crestmont Capital, conventional lenders prefer a debt-to-revenue ratio below 35%, a debt-to-equity ratio under 2.0 for small businesses (SBA lenders look for below 3.0), and they often treat a personal debt-to-income above 43% as a disqualifier. For a partnership taking on a line, the owners' personal balance sheets still matter.

Accounts receivable and recurring revenue

Because working capital lines are repaid from cash flow and often backed by receivables, underwriters dig into your A/R. They watch customer concentration — when one client represents more than roughly 20–25% of receivables — along with the aging distribution, where a high share of 90-plus-day invoices signals collection problems. Many AR-backed lines advance 70–85% of eligible invoice value as the borrowing base. For an accounting firm, predictable retainer and tax-season billing is a strength: recurring revenue gives lenders confidence the line will be repaid even through seasonal dips.

To present well, keep your DSCR above 1.25, clean up aged receivables before applying, and document the recurring portion of your book. For more on this, see our guides to working capital for CPA firms and cash flow management.
