Business Line of Credit: How It Works and How to Qualify

A cabinetry company in Cypress wins a $180,000 commercial job in July. The project requires $55,000 in materials upfront before the first draw from the general contractor. The business has the contract and the crew. What it does not have is $55,000 in cash sitting in the bank.

Without a business line of credit, the owner has a few options. Turn down the job. Delay purchasing materials until draws arrive, which delays the schedule and risks the relationship. Or borrow from a personal credit card at 22% interest.

With a business line of credit already in place, the owner draws $55,000, pays for materials, completes the first phase of the project, receives the GC draw, and repays the line. Total interest cost at 8.5%: approximately $350 for 30 days of use.

That is what a business line of credit is for. It is working capital access when timing creates a gap between what you need to spend and what you have in the bank.

How a Business Line of Credit Works

A business line of credit is a revolving credit facility. The lender approves you for a maximum credit limit. You draw from it when needed, repay what you borrowed, and the capacity is available again.

It is not a lump sum. It is access. A $100,000 line of credit means you can draw up to $100,000 at any point, in any amount, for any business purpose.

Interest is charged only on the outstanding balance, not the full credit limit. If your line is $100,000 and you have drawn $30,000, you pay interest on $30,000.

The two most common structures:

Revolving line of credit. As you repay what you borrowed, the available balance replenishes. The line stays open indefinitely, typically with an annual review and renewal. This is the most common structure for small business working capital lines.

Non-revolving line. Similar mechanics, but once funds are drawn and repaid, that capacity is not restored. Less common for working capital; more common for specific project financing.

How It Differs From a Term Loan

The distinction between a line of credit and a term loan is important because they serve different purposes.

Term loan: You receive a lump sum upfront, repay it on a fixed schedule over a defined period (typically 2 to 10 years), and the account closes when the balance reaches zero. Term loans are appropriate for capital expenditures, equipment purchases, real estate acquisitions, and any use where you need a specific amount for a specific investment.

Line of credit: You draw as needed, repay as cash flow allows (subject to minimum payments), and the facility remains available for repeated use. Lines of credit are appropriate for working capital, seasonal cash flow gaps, inventory purchasing, and situations where the timing of cash inflows and outflows does not perfectly align.

A Houston landscaping company that needs $120,000 for new equipment uses a term loan. The same company that needs to cover payroll during the slow November-January season while waiting for commercial contracts to pay out uses a line of credit.

Types of Business Lines of Credit

Unsecured line of credit. No specific collateral required. Lenders rely primarily on creditworthiness, business financial history, and cash flow. Harder to qualify for, especially for newer businesses. Interest rates are typically higher than secured lines because the lender has no collateral claim.

Secured line of credit. Backed by collateral, typically accounts receivable, inventory, or other business assets. Lenders may also accept a blanket lien on business assets. Because the lender has a collateral claim, rates tend to be lower and qualification requirements somewhat more accessible.

SBA CAPLines. Small Business Administration programs that provide government-backed lines of credit for working capital and seasonal needs. More accessible for small businesses with limited credit history, but the application process is more involved than a conventional line.

HELOC-based business financing. Some business owners use home equity to fund business working capital. This is technically personal credit used for business purposes, not business credit, and it creates personal liability exposure.

What Lenders Look For

Qualifying for a business line of credit requires meeting thresholds across several criteria. Different lenders weight these differently, but the core factors are consistent.

Time in Business

Most traditional lenders want to see at least two years of operating history. Some community banks and credit unions in Houston will work with businesses that are 12 to 18 months old if other qualifications are strong. Online lenders often have lower minimums (six months to one year).

Annual Revenue

Lines of credit are typically sized at a percentage of annual revenue. A common ratio is 10% to 15% of annual revenue for an unsecured line. A Houston business with $800,000 in annual revenue might qualify for a $80,000 to $120,000 line.

Minimum annual revenue requirements vary by lender. Many traditional banks require $250,000 or more. Online business lenders may go as low as $100,000.

Credit Score

For small businesses, lenders often look at both personal credit and business credit. A personal credit score of 680 or above is generally considered acceptable for most business lines of credit. Scores below 650 significantly narrow your options or push you toward secured products at higher rates.

Business credit scores (PAYDEX, Experian Business, Equifax Business) become more relevant as your business matures and builds its own credit history. Strong business credit can reduce the personal guarantee requirement.

Cash Flow and Debt Service Coverage

The lender wants to see that your business generates enough cash flow to service the debt. A debt service coverage ratio (DSCR) of 1.25 or above is typically required for conventional lines. This means the business generates $1.25 in cash flow for every $1.00 of debt obligation.

A business with $100,000 in annual net operating income and $70,000 in annual debt payments (existing loans, leases, and the projected line payments) has a DSCR of approximately 1.43. A business with $50,000 in net operating income and $60,000 in debt obligations has a DSCR of 0.83, which is below coverage and will struggle to qualify.

Financial Statements

Banks require organized, accurate financial statements. At minimum: two years of business tax returns, current year profit and loss, current balance sheet, and six months of business bank statements.

A business with clean books in QuickBooks that can produce these documents within 24 hours is in a fundamentally different position than one that needs to reconstruct two years of records before applying. The quality of your financial records directly affects both whether you qualify and how quickly the process moves.

Collateral (for Secured Lines)

For secured lines, the lender will value the collateral and typically lend against a percentage of that value. Accounts receivable might be eligible for 70% to 85% of eligible receivables. Inventory at 50% to 60%. Equipment at 50% to 70% of liquidation value.

What the Application Process Looks Like

Applying for a business line of credit with a traditional Houston bank or credit union involves:

Initial conversation with a business banker to assess fit
Application with business and personal information, ownership structure, and purpose of the line
Submission of financial documents: tax returns, financial statements, bank statements
Credit review (personal and business)
Underwriting: the lender analyzes your financial position and assigns a risk profile
Term sheet or commitment letter with the proposed rate, term, and collateral requirements
Legal review and closing documents
Account opening and funding

This process takes two to six weeks at a traditional bank. Online lenders compress the timeline significantly: some can approve and fund within three to five business days, though rates are typically higher.

Interest Rates and Fees on Business Lines of Credit

Rates on business lines of credit in 2026 depend on the lender, your creditworthiness, and whether the line is secured.

Traditional bank (secured, strong credit): Prime rate + 0.5% to 2.5%. With prime at 7.5% in early 2026, that is approximately 8.0% to 10.0%.

Traditional bank (unsecured): Prime + 2% to 4%. Approximately 9.5% to 11.5%.

SBA CAPLine: Similar to conventional bank rates with a government guarantee component. Often 9.0% to 11.0%.

Online lenders (Bluevine, Fundbox, OnDeck): Variable, often ranging from 15% to 40% depending on creditworthiness. Convenient and fast, but the cost of capital is significantly higher.

Common fees to review:

Annual fee: $0 to $500 on most small business lines
Draw fee: Some lenders charge $5 to $20 each time you draw from the line
Maintenance fee: Some lenders charge monthly if the line goes unused
Prepayment fee: Less common for lines, but exists with some products

What Disqualifies Applications

Consistent patterns that lead to denials:

Thin credit file. A business with no trade accounts, no business credit card, and no reporting history is invisible to business credit bureaus. Some lenders will work with this situation, but rates are less favorable.

Tax liens. An IRS or state tax lien against the business is a serious disqualifier for most lenders. Resolving tax debt before applying is important.

High existing debt load. If existing term loans and leases already consume most of your cash flow, adding a line of credit leaves the lender little cushion.

Cash flow inconsistency. A business with large monthly revenue swings and frequent overdrafts on bank statements signals cash flow management problems that make lenders cautious.

Incomplete or disorganized financials. A lender who receives tax returns that do not match the financial statements, or bank statements that show income not reflected in the tax returns, will pause the process or deny.

Houston-Specific Lenders Worth Knowing

Community banks and credit unions in Houston often have more flexibility on small business lines of credit than national banks.

Frost Bank, Amegy Bank, Woodforest National Bank, and Houston-based credit unions have small business banking divisions familiar with Houston’s construction, energy services, restaurant, and retail sectors. Relationships matter at these institutions.

The Houston SBDC (Small Business Development Center) at the University of Houston provides free guidance on loan readiness and can help you identify which lenders are appropriate for your situation. Their advisors work with applicants before they approach lenders.

The SBA district office in Houston manages the CAPLine and 7(a) programs. SBA loans take longer to process but provide more accessible qualification thresholds for businesses that do not meet conventional bank criteria.

Preparing Your Business to Qualify

If a business line of credit is a 12-month goal rather than an immediate need, the preparation steps are clear.

Get the books current and accurate. Two years of clean tax returns and matching financial statements are the core of any bank application.

Build trade line history. Open net-30 accounts with vendors that report to Dun & Bradstreet and make every payment on time.

Open a business credit card and use it consistently. Pay the balance in full to build payment history without debt accumulation.

Reduce or restructure existing high-interest debt if it is compressing your DSCR.

Establish or deepen your banking relationship. Banks extend more favorable terms to businesses they know.
