What Lenders Require for a Business Line of Credit

Underwriters run through the same handful of tests, and knowing them tells you where to spend your preparation time:

• Time in business: lenders want a history of operating revenue, and newer companies are often steered toward smaller or more heavily secured lines.
• Cash flow: the debt service coverage ratio compares operating income to annual debt payments. Banks want it comfortably above 1.0, which means income covers payments with a cushion.
• Credit: the owners' personal credit and the business's own credit file both come into play, particularly when a personal guarantee is required.
• Existing debt: every current loan, lease and card balance counts against your capacity, so list them before the lender does.
• Collateral: receivables, inventory, equipment, real estate or a blanket lien on business assets, depending on the product.

Rates on bank lines commonly move with the bank prime rate, which was 6.75 percent in mid-2026¹. Kansas City Fed survey data showed average small-business bank loan rates ranging from 6.37% to 10.98% across loan and rate types in the first quarter of 2026², which shows how much your profile moves the price.

An unsecured line relies on your credit and cash flow, and lenders usually limit its size. A secured line lets you borrow more because the lender holds a claim on assets, and the most common secured structure for operating companies is a borrowing base.

With a borrowing base, your available credit is a percentage of eligible receivables and sometimes inventory, recalculated as those balances change. Say your eligible receivables are $300,000 and the lender advances 80% against them: you can draw up to $240,000, even if the stated line is larger. If a customer goes past the lender's aging cutoff, that invoice drops out of the base and your availability shrinks.

Ask which assets are eligible, how often the base is recalculated, and whether the lender takes a blanket lien on everything, which can block you from adding other financing later. Sizing the request matters too: request enough to cover your longest payment gap, not a round number that impresses no one.

Lenders respond faster to a complete, consistent package. Use this order:

1. Write a one-page request stating the amount, what the line is for and how it will be repaid from operating cash flow.
2. Pull three years of business tax returns and current-year financial statements, and make sure the totals reconcile.
3. Prepare accounts receivable and accounts payable agings, plus a schedule of all existing debt.
4. Gather bank statements and be ready to explain any large or unusual deposits.
5. Collect owner information: personal financial statements, tax returns and ownership percentages.
6. Confirm your legal documents are current, including formation papers, licenses and insurance.

The full document list, with why each item matters, is in the bank loan application checklist. The same paperwork also supports most other bank financing, so it is worth assembling even if you end up choosing a different product.

The interest rate is only part of what you pay. Compare offers on the whole fee schedule:

• Draw fees: a charge each time you pull funds, which punishes frequent small draws.
• Non-use or unused-line fees: a charge on the portion you do not borrow, which matters if you want the line only as a safety net.
• Annual renewal and maintenance fees: charged on the anniversary whether you draw or not.
• Clean-up periods: some lines require the balance to reach zero for a set number of days each year.
• Floors and indexes: a rate floor means you do not benefit fully if the index falls.

The draw fee and non-use penalty guide shows how to compare these, and drawdown timing explains when borrowing early costs you more than it protects.

Applications fail less often on low scores than on avoidable friction. The most common problems are statements that do not reconcile with tax returns, an unexplained drop in monthly deposits, a request that is too large for the cash flow shown, and undisclosed debt that turns up in a credit pull.

After approval, lenders can reduce or freeze a line if you breach a covenant, miss financial reporting deadlines or the borrowing base falls. Read the default and material change language before you sign, and keep a liquidity cushion outside the line so a freeze does not stop payroll.

If your business sells to other companies on credit terms, an unsecured line for a consulting firm shows what a professional-services profile looks like to lenders.
