Borrowing for a small business: the options, ranked

Small-business borrowing runs from genuinely cheap capital to products that would embarrass a payday lender, and they're all marketed with the same friendly vocabulary. The two questions that sort everything: what is the true annualized cost (APR, not 'factor rate' or 'fee'), and will the thing you're buying with the money earn more than that cost? Debt that funds a return is a tool. Debt that funds losses is a countdown.

The menu, from cheapest to most dangerous

• Business line of credit (bank or credit union): revolving, draw-as-needed, pay interest only on what you use — typically ~8–14% APR. The single most useful product for cash-flow gaps.
• SBA loans (7(a), microloans): government-guaranteed bank loans with strong rates (often prime + 2–4%) and long terms; paperwork-heavy and slow (weeks to months), best for large, planned investments.
• Equipment financing: the equipment secures the loan, so rates stay moderate (~7–15%) and approval is easier; the term should never outlive the machine.
• Business credit cards: fine as float paid monthly; as borrowing, 20–28% APR — short emergencies only, with a payoff date.
• Online term loans (fintech lenders): fast money at 15–40%+ APR; read the total repayment number, not the pitch.
• Invoice factoring: selling receivables at a 1–5% monthly discount — expensive but at least tied to money you've genuinely earned.
• Merchant cash advances: an advance repaid by skimming daily sales at a 'factor rate' that hides effective APRs of 40–200%+. The payday loan of business finance and a leading cause of small-business death spirals.

Borrow for returns, bridge for timing, never for losses

Three honest uses of business debt: funding an asset with a calculable return (equipment, buildout, inventory that turns), bridging a timing gap you can see the far side of (a signed contract's slow payment cycle, a known seasonal trough), and smoothing lumpy-but-profitable operations with a line of credit. The dishonest use is covering chronic losses — borrowing to make payroll in a business that loses money monthly doesn't buy a solution; it buys a bigger version of the same problem with interest attached. If the P&L is negative and the plan is 'a loan,' the plan is actually 'fix pricing, costs, or the model,' and the loan just delays the meeting.

The borrowing playbook

1. Open a line of credit before you need it — approval is easiest during strong quarters, and unused lines cost little or nothing.
2. Write the return math first: what the money buys, what it earns monthly, and the breakeven month. If you can't write it, don't borrow it.
3. Get at least two quotes and convert every offer to APR and total dollars repaid — the only two numbers that let products compete honestly.
4. Match the term to the asset: 5-year money for equipment, 90-day money for inventory, revolving money for cash-flow gaps.
5. Size payments to survive your worst realistic month, not your average one.
6. Start SBA conversations early if the need is large and plannable — cheap money is slow money.

The bottom line

Rank your options: line of credit and SBA first, equipment financing for equipment, cards only as paid-in-full float, and merchant cash advances never, or one desperate step before never. Convert everything to APR, borrow only against written return math or visible timing gaps, and set up the cheap credit while business is good. Debt amplifies whatever it touches — make sure what it's touching is a plan.

The menu, priced

The single most expensive mistake in small-business borrowing is comparing products by their quoted numbers instead of their true annual cost. A merchant cash advance quoting a 1.3 factor rate sounds like 30% — but repaid daily over eight months, its effective APR routinely lands north of 70%. Meanwhile the SBA loan that actually is 12% gets skipped because the paperwork takes six weeks. The discipline is simple: convert everything to APR, borrow against a specific revenue-generating purpose rather than to patch chronic losses, and set up the line of credit during a strong quarter — banks lend most willingly to businesses that do not urgently need it.
