Small Business Loan vs Line of Credit: Which One Do You Actually Need?

The fundamental difference: what each product is built for

The confusion between these three products is understandable — banks market all of them as "small business financing" — but they serve distinct purposes and are underwritten differently.

A term loan provides a lump sum upfront, which you repay over a fixed period with scheduled payments. It's built for a specific, defined capital need: buying a business, purchasing equipment, funding a buildout. Once drawn, you can't reborrow the repaid principal. SBA 7(a) term loans go up to $5 million, making them the primary vehicle for business acquisitions in the United States.

A line of credit is a revolving facility with a maximum limit. You draw against it as needed, repay what you've drawn, and the available balance replenishes. It's designed for working capital cycling — covering the gap between paying suppliers and collecting from customers, managing seasonal inventory, bridging payroll during slow periods. It is not designed to hold a large, permanent balance.

An SBA loan is a term loan with a government guarantee attached. The SBA guarantee changes the lender's risk economics, which lets them offer longer terms, lower down payments, and rates within regulated caps. It's a financing mechanism applied to a term loan structure — not a separate product category.

The practical hierarchy: term loans for capital acquisition, lines of credit for working capital management, SBA loans when you want the best available terms on a term loan.

Term loans: when to use them

Use a term loan when you have a specific capital need with a defined amount and a repayment source that's predictable over time.

Acquisition financing is the clearest use case. Buying a business or franchise requires a fixed amount — the purchase price minus your down payment — that you repay from the acquired business's cash flow over a defined term. SBA 7(a) requires a minimum 10% cash injection from the buyer's own funds. Lenders underwriting these deals require a DSCR of at least 1.25x, meaning the business must generate $1.25 in net operating income for every $1.00 of annual debt service. On a $500,000 acquisition loan at 12% over 10 years, monthly payments run approximately $7,100, so the business needs to clear $8,875 per month before that obligation.

Equipment purchases follow the same logic. The equipment costs a specific amount, generates specific revenue or cost savings over its useful life, and is repaid over a term matching that life. The term loan structure fits exactly.

Leasehold improvements work the same way. A franchise buildout costs a defined amount, the franchise agreement runs 10 years, and the improvement cost amortizes over the same period.

What term loans are not for: working capital. If you need ongoing access to cash for inventory, payroll gaps, or operating expenses, a term loan gives you a lump sum you draw down and can't replenish. A line of credit is the right product for that need.

Lines of credit: when to use them

Lines of credit are built for working capital cycling — the ongoing need for short-term capital that arises from the timing mismatch between paying obligations and receiving revenue.

Seasonal businesses are the clearest example. A landscaping company that generates 80% of revenue April through October needs capital November through March to maintain operations. A line of credit covers the low season and gets paid down as revenue recovers.

Invoice-based businesses have the same structural need. A B2B service business that invoices net-30 or net-60 has receivables that need bridging. Draw on the line while waiting for customer payment, repay when payment arrives.

Inventory management creates similar cycles. A retail business that needs to purchase fall inventory in August before September sales materialize can draw on the line in August and repay it from September revenue.

What lines of credit are not for: acquisition financing. Drawing your full credit line to buy a business and carrying that balance as a permanent loan is exactly the wrong structure. Lines are priced as revolving products, not permanent capital, and lenders monitoring line usage will flag a permanently maxed balance as a credit concern. If you need $400,000 to buy a business, you need a term loan — not a maxed-out revolving line you're treating like one.

SBA loans: not a separate category, but a better version of a term loan

The SBA guarantee is a financing mechanism that improves the terms of a term loan — it doesn't create a new product type.

When a bank makes an SBA 7(a) loan, the SBA agrees to cover up to 85% of the lender's loss if the borrower defaults. This reduces the lender's risk, which allows them to offer longer terms (10 years vs 5–7 for conventional), lower down payments (10% vs 20–30%), rates within regulated caps, and approval for deals they'd decline without the guarantee. The maximum SBA 7(a) loan is $5 million — sufficient to fund most small business acquisitions, including mid-size franchise territory purchases.

For working capital needs that arise alongside an acquisition, some SBA 7(a) loan structures include a working capital tranche within the same loan. This is different from a separate line of credit — it's a term loan component, not revolving, and it repays on the same schedule as the acquisition portion.

SBA 7(a) is the right structure for business acquisition when you're buying an existing business or franchise, want the longest available term to minimize monthly payments, need the lowest possible down payment (10% cash injection), and want government-backed underwriting for a deal that's fundable but complex.

The right combination for franchise buyers

Most franchise buyers end up needing both products — in sequence.

Phase one is acquisition. An SBA 7(a) term loan covers the purchase price minus the buyer's 10% down payment. This funds at closing and begins amortizing immediately from business cash flow.

Phase two is operations. Once the business is running, a business line of credit covers working capital needs — inventory builds before a seasonal peak, equipment that needs replacing mid-year, a vendor payment that falls before a strong revenue month. Many franchisors recommend establishing a line of credit in the first year of operation as a cash flow buffer.

If you have $50,000 or more in a qualifying retirement account, a Rollover for Business Startups (ROBS) lets you use that capital as the equity injection without triggering a taxable distribution. ROBS requires a C-corp structure and a specialized plan administrator — the minimum that makes it economically viable is typically $50,000 given setup and administration costs. It eliminates the need to produce the down payment from liquid savings.

For buyers who need under $50,000 in startup or working capital, SBA microloans are distributed through nonprofit intermediary lenders at 8%–13%. The maximum SBA microloan is $50,000, and intermediaries like Accion and Kiva serve borrowers who don't meet bank minimums — useful when you're building credit while operating an acquired business in its early months.

The common mistake is trying to use one product for both purposes. Buyers who fund the acquisition with a line of credit end up with permanently maxed revolving debt at working-capital rates. Plan for both from the start.
