Working capital for small business: a straight-talk guide to your real options
If you're an SMB owner trying to figure out which financing product makes sense for your situation, you've probably noticed the market is loud. Every lender claims to be the "fastest," "lowest cost," or "most flexible." Most of those claims are technically true under specific conditions and meaningless under others. This is a guide to the six product categories I work with most, what each is actually good for, and the most common mistake owners make when comparing them.
The six categories
Every SMB financing conversation maps onto one of these six product categories. Pick your category first; the specific lender within the category is a secondary decision.
| Product | Typical size | Speed | Cost (rough) | Best fit |
|---|---|---|---|---|
| Working capital advance | $25K–$500K | 24–72 hrs | 30–80% APR-equivalent | Speed + bridge |
| Term loan | $50K–$2M | 1–4 weeks | 10–25% APR | Defined use, lower cost |
| Line of credit | $25K–$500K | 1–3 weeks | 9–20% APR (drawn) | Bursty cash needs |
| Equipment financing | $10K–$5M | 1–2 weeks | 7–18% APR | Buying specific equipment |
| Invoice factoring | 10–90% of AR | 24–48 hrs | 1–4% per invoice | Slow-paying B2B customers |
| SBA 7(a) / 504 | $50K–$5M | 60–120 days | Prime + 2.75–4.75% | Patient + cheapest |
1. Working capital advances (and MCAs)
Short-term, revenue-based capital. The lender advances you a lump sum and collects payment as either a fixed daily/weekly ACH or a percentage of your daily revenue until a multiple of the advance is paid back. Two structural advantages set this category apart: speed (funded in 24-72 hours with minimal paperwork) and credit-tolerant underwriting (decisions are based on your monthly revenue and bank deposit history — not your credit score).
Owners use working capital advances and merchant cash advances (MCAs) for: capturing time-sensitive opportunities (inventory deals, vendor discounts, opportunistic acquisitions), bridging known cash gaps (slow customer payment cycles, seasonal patterns), expansion capital that traditional banks decline due to credit history, and operating capital while business credit is being rebuilt.
The headline cost (30-80% APR-equivalent) is higher than a traditional bank loan because the lender is taking on speed risk and credit risk that traditional underwriters won't. For the right scenarios — and they're more common than the SMB world often acknowledges — that trade is genuinely worth making. (See: APR vs factor rate explainer.)
Best fit: any time speed of capital matters more than the absolute lowest cost; any time you've been declined by traditional credit-based lenders; any time you have a clear use of funds that justifies the cost (deal opportunity, growth investment, cash bridge).
2. Term loans
Fixed amount, fixed payment, fixed term. The traditional small business loan structure. Underwriting takes 1–4 weeks (full financials, tax returns, P&L, balance sheet, sometimes a personal guarantee), but the cost is meaningfully lower than a working capital advance — typically 10–25% APR depending on credit profile and term length.
Owners use term loans for: defined-use cases (equipment, expansion, refinance, acquisition), and any time the underwriting work is justified by the cost savings vs working capital advances.
Don't use term loans for: general operating capital you'll need to refinance every 12–18 months — the underwriting overhead doesn't pay off if you're constantly re-applying.
3. Lines of credit
A revolving credit facility you draw against as needed. You only pay interest on the drawn balance. Underwriting is similar effort to a term loan, but the result is optionality: capital available when you need it without re-applying.
Owners use lines of credit for: bursty cash needs (payroll smoothing, AR float, opportunistic inventory), seasonal businesses with predictable peaks/troughs, and any business where the timing of capital needs is hard to forecast precisely.
Don't use lines of credit for: long-term capital you'll never repay (the cost adds up), or as a substitute for a term loan where the use case is well-defined upfront.
4. Equipment financing
Loan or lease secured by the specific equipment being purchased. Because the equipment serves as collateral, the underwriting is faster and the rate is lower than unsecured options — typically 7–18% APR. Most equipment vendors have preferred lenders, but shopping it out almost always saves money (vendor-preferred rates are rarely the best rates).
Owners use equipment financing for: vehicles, machinery, point-of-sale systems, restaurant kitchen equipment, manufacturing equipment, medical devices, IT infrastructure. Almost any depreciating physical asset.
Don't use equipment financing for: non-equipment expenses (the lender will say no), or for equipment you'll fully replace within 24 months (lease may be cheaper than loan).
5. Invoice factoring (AR financing)
You sell your unpaid invoices to a factor at a discount; they advance you 80–90% immediately and collect from your customer. When the customer pays, you get the residual minus the factor's fee (typically 1–4% per invoice depending on customer credit + age).
Owners use invoice factoring when: customers pay on NET-30/60/90 terms, the business is B2B with creditworthy buyers, and the cash gap between delivering the work and getting paid is the binding constraint.
Don't use invoice factoring for: consumer-facing businesses (B2C invoices generally aren't factorable), or businesses where customers might object to the factor's collection process (some industries are sensitive to a third party calling about payment).
6. SBA loans (7(a) and 504)
The cheapest cost of capital available to most SMBs — Prime + 2.75–4.75% — but the slowest and most paperwork-intensive. SBA 7(a) is general-purpose; SBA 504 is specifically for owner-occupied real estate and major equipment.
Owners use SBA loans when: they have 60–120 days of patience, they need long terms (7–25 years), and they can document strong financials. The application process is rigorous (3 years tax returns, full financial statements, debt schedule, business plan) but the resulting capital is often half the cost of any other option on this list.
Don't use SBA loans for: anything urgent, anything where your financials don't yet justify it (early-stage businesses), or anything where the use of funds doesn't fit the SBA's allowable categories.
The right framework for comparing offers
Most owners compare offers by headline rate alone. The more useful comparison: total cost in actual dollars over your realistic repayment period, divided into the value the capital lets you create.
Factor rates and APR aren't directly comparable on their own. A 1.35 factor on a $100K advance with a 6-month early payoff (some lenders offer 10-25% off remaining balance) has a very different effective cost than the same 1.35 factor stretched to 18 months. Term, prepayment terms, and use of funds all matter.
The questions that actually drive the right decision: (1) what's the all-in dollar cost? (2) what's the value of the capital deployed in your business? (3) how fast can you actually access each option? (See: APR vs factor rate explainer.)
"What if my credit isn't great?"
This is the question that most often determines product fit. Traditional bank loans, SBA loans, and most term loans are heavily credit-driven — a low FICO score (personal or business) usually means decline or punitive pricing.
Working capital advances and MCAs are revenue-driven, not credit-driven. The lender's underwriting is based on a guarantee of future receivables — if your business has reliable monthly revenue, you can typically access capital even with imperfect credit. This is the structural advantage of the working capital category: it unlocks capital that traditional credit-based lenders won't provide, and it does so on a timeline that fits real business needs.
If you've been declined by a bank or SBA lender, don't assume you're out of options. Strong monthly revenue is itself the qualification.
How I help owners pick
The honest answer is: there's no universal best product. Each of these six categories is the right answer for a specific business at a specific point in its growth. My job as a broker is to: (1) listen to where you actually are, (2) shortlist the 2–3 product categories that make sense for that situation, (3) get quotes from the lenders most likely to underwrite your file well, and (4) walk you through the trade-offs in plain English.
The 5-fact intake (industry, years in operation, monthly revenue, amount needed, use of funds, time preference) is usually all I need to give you a meaningful first conversation.
