There are six places a US small business can get funded — banks, SBA lenders, credit unions, online/fintech lenders, revenue-based (MCA) marketplaces, and non-loan sources like equipment vendors and asset-based lenders — and seven core funding types that ride on top of them: term loans, SBA loans, business lines of credit, equipment financing, invoice/AR financing, revenue-based financing (merchant cash advance), and business credit cards. The right choice is rarely about the lowest posted rate. It is about which structure your cash flow can actually carry, how fast you need the money, and whether a lender will approve you at all given your credit, time in business, and deposits. This guide compares all six sources and all seven types the way an underwriter reads a file — by approval odds, speed, and weekly cash-flow load — so you can shortlist in minutes instead of applying blindly and collecting declines.
Key takeaways
- Six sources fund US small businesses: banks, SBA lenders, credit unions/CDFIs, online/fintech lenders, revenue-based (MCA) marketplaces, and specialized non-loan sources.
- Seven core funding types: term loans, SBA loans, lines of credit, equipment financing, invoice/AR financing, revenue-based financing (MCA), and business credit cards.
- Banks and SBA lenders offer the lowest cost but the highest approval bar and slowest timelines (weeks to ~2 months).
- Revenue-based / MCA marketplaces underwrite on bank deposits and revenue rather than credit score — typically FICO 500+, ~$10,000 minimum, funded in about 24–48 hours.
- The lowest posted rate is often unavailable in practice; the right choice is the structure your cash flow can carry and a lender will actually approve.
- Equipment and invoice financing are secured by a specific asset, so approval leans on that asset rather than overall creditworthiness.
- No legitimate funder guarantees approval — treat 'guaranteed funding' claims as a red flag.
The 6 sources of small-business funding
Before you look at loan types, understand who is on the other side of the desk. Each source has a different appetite, a different speed, and a different bar for approval.
- Traditional banks. Lowest cost of capital, deepest relationships, and the slowest, most documentation-heavy underwriting. They generally want strong personal credit (often 680+), two-plus years in business, and clean, profitable financials. Best for established, bankable businesses that can wait weeks.
- SBA lenders. Banks and non-bank lenders originating loans backed by a partial US Small Business Administration guaranty (7(a), 504, microloans). The guaranty lets them stretch terms and approve files a conventional loan would decline, but the tradeoff is paperwork and a timeline usually measured in weeks to a couple of months.
- Credit unions and CDFIs. Member-owned and mission-driven lenders. Often more flexible and relationship-friendly than a big bank, sometimes with lower fees, but membership requirements and smaller lending limits apply. CDFIs in particular fund businesses in underserved markets that mainstream banks pass on.
- Online / fintech lenders. Technology-first lenders that automate underwriting from bank data and credit. Faster than banks (often days), broader credit box, higher cost. This is where most modern term loans and lines of credit for younger businesses actually get done.
- Revenue-based / MCA marketplaces. Instead of one lender, a marketplace matches your file against many funders that approve on bank deposits and revenue rather than credit score. Typical fit: at least ~$10,000 in funding need, FICO 500+, and consistent deposits. Decisions in about 24–48 hours. This is the widest door when speed and approvability matter more than the lowest rate. See our complete business funding guide for how these files are underwritten.
- Non-loan / specialized sources. Equipment vendors and captive finance arms (they finance the asset they sell you), invoice/AR factors (they advance against your receivables), and asset-based lenders (they lend against inventory, equipment, or receivables). These are structured around a specific asset, not your overall creditworthiness.
The 7 funding types, in plain terms
These are the structures the six sources above actually offer. Most owners only need to understand what each one does to weekly or monthly cash flow.
- Term loan. A lump sum repaid over a fixed period on a fixed schedule. Predictable, good for one-time investments (buildout, a big hire, an acquisition). Cost and term vary enormously between a bank term loan and an online term loan.
- SBA loan. A term loan (or sometimes a line) with a government guaranty behind it. Longer terms, competitive pricing, larger amounts — in exchange for documentation and time.
- Business line of credit. A revolving limit you draw from, repay, and reuse. You pay for what you use. Ideal for smoothing cash flow gaps, payroll timing, and inventory cycles rather than a single big purchase.
- Equipment financing. A loan or lease secured by the equipment itself. The asset is the collateral, so approval leans on the equipment's value and your ability to pay, not just credit.
- Invoice / accounts-receivable financing. An advance against unpaid B2B invoices. Turns slow receivables into working capital now. Cost is tied to how long the invoice takes to get paid.
- Revenue-based financing (merchant cash advance). Funding repaid as a set share of future sales or a fixed daily/weekly remittance that flexes with your deposits. Approval is driven by revenue and bank activity, not credit score. Fastest to fund and the most forgiving on credit; in exchange, it carries a higher cost of capital and is best used for short, revenue-generating purposes.
- Business credit card. Revolving, unsecured, widely available, good for everyday spend and short float — but a poor tool for large, longer-horizon capital needs.
Side-by-side: how the funding types compare
The figures below are illustrative ranges to show relative positioning, not quotes. Actual terms depend on your file, and nothing here is guaranteed.
| Funding type | Typical source | Speed to fund | Approval bar | Best for |
|---|---|---|---|---|
| Bank term loan | Banks, credit unions | Weeks | High (strong credit + financials) | Established, profitable businesses |
| SBA loan | SBA lenders | Weeks to ~2 months | Medium-high, doc-heavy | Larger, longer-term investments |
| Line of credit | Banks, fintech | Days to weeks | Medium | Recurring cash-flow gaps |
| Equipment financing | Vendors, fintech, banks | Days | Medium (asset-secured) | Buying machinery/vehicles |
| Invoice / AR financing | Factors, ABL lenders | Days | Tied to your customers' credit | Slow-paying B2B receivables |
| Revenue-based / MCA | RBF/MCA marketplace | ~24–48 hours | Lower — FICO 500+, revenue-driven | Fast working capital, thinner credit |
| Business credit card | Card issuers | Days | Personal-credit driven | Everyday spend, short float |
A realistic example: same business, three paths
Consider, for example, a specialty coffee roaster doing roughly $85,000 a month in deposits, owner FICO around 610, 18 months in business, needing about $40,000 to buy a larger roaster and cover a seasonal inventory build. Here is how the shortlist actually shakes out.
| Path | Likely outcome | Cash-flow feel |
|---|---|---|
| Bank term loan | Probable decline or long delay — time in business and credit are below a typical bank threshold | Lowest cost if approved, but likely not available in time |
| Equipment financing (for the roaster) | Reasonable fit for the machine itself, since the roaster is collateral | Predictable fixed payment tied to the asset; doesn't cover the inventory build |
| Revenue-based financing via marketplace | Strong approval odds — deposits and revenue carry the file, FICO 500+ clears the bar, funds in about 24–48 hours | Remittance flexes with daily sales; higher cost of capital, best kept to the short revenue-generating window |
The instructive part: the "cheapest" option (the bank) is effectively unavailable, and the smart move may be to combine — equipment financing for the roaster plus revenue-based working capital for the inventory build — rather than force one product to do two jobs.
Decision framework: works best when / avoid when
Match the structure to the situation. Read down to the row that sounds like you.
Bank or SBA loan — works best when you have 2+ years in business, solid credit, documented profitability, and a longer-horizon investment (real estate, acquisition, major buildout) where the lowest rate matters most and you can wait. Avoid when you need money in days, your credit or time in business is thin, or the paperwork burden would stall the opportunity.
Line of credit — works best when your need is recurring and unpredictable (payroll timing, inventory cycles) and you want to pay only for what you draw. Avoid when you actually need one large lump sum for a single purpose — a term structure fits that better.
Equipment financing — works best when the money is going toward a specific machine or vehicle that holds value; the asset does the collateral work. Avoid when you need general working capital not tied to an asset.
Invoice / AR financing — works best when you're B2B, your cash is trapped in 30–90 day receivables, and your customers have good credit. Avoid when you're primarily B2C or your invoices are small and numerous.
Revenue-based financing / MCA — works best when you have steady deposits, need capital fast (24–48 hours), have credit that banks decline (FICO 500+), and the use of funds generates revenue quickly enough to carry a higher cost of capital. Avoid when your margins are thin and the funds won't produce a near-term return, or when you have the credit and time to qualify for materially cheaper capital and can wait for it. Used deliberately, it is the widest, fastest door; used to plug a structural hole, it gets expensive fast.
Business credit card — works best when the spend is everyday and you'll clear balances quickly. Avoid when you're financing a large, longer-term need — that's what term products exist for.
How lenders actually decide (and how to improve your odds)
Every source above weighs some mix of five things: personal and business credit, time in business, revenue and its consistency, cash flow visible in your bank statements, and collateral. Banks weight credit and financials heavily. Asset-based and equipment lenders weight the asset. Revenue-based marketplaces weight deposits and revenue over credit score — which is precisely why they approve files the first two sources decline.
Three moves improve almost any application: keep your business bank account clean (avoid negative days and excessive NSFs, since underwriters read your statements line by line), separate business and personal finances so revenue is legible, and apply to the source whose bar you actually clear rather than reaching for a product you'll be declined for. A stack of bank declines can cost you weeks. If speed and approvability are the constraint, start with the source built for that. Our business funding guide walks through preparing a clean file.
Which should you choose?
Rank your top constraint. If it's lowest cost and you can wait, start with a bank, credit union, or SBA lender. If it's a specific asset, use equipment or invoice financing built around that asset. If it's recurring flexibility, a line of credit. And if it's speed and getting approved at all — because your credit is rebuilding, your business is young, or the opportunity won't wait — a revenue-based / MCA marketplace that underwrites on your deposits and revenue is usually the most realistic path, with decisions in about 24–48 hours and a bar starting at roughly $10,000 and FICO 500+. No responsible funder can promise approval, and you should walk away from anyone who says "guaranteed." The goal isn't the fanciest product; it's the one your cash flow can carry and a lender will actually say yes to.
Frequently asked questions
What's the difference between a business loan source and a funding type?
A source is who provides the money — a bank, an SBA lender, a credit union, an online lender, a revenue-based marketplace, or a specialized asset-based source. A funding type is the structure of the money itself, such as a term loan, a line of credit, or revenue-based financing. One source often offers several types, and the same type (a term loan, say) can cost very differently depending on the source.
Which type of business loan is easiest to get approved for?
Generally revenue-based financing through an MCA marketplace, because approval is driven by your bank deposits and revenue rather than your credit score. Typical fit is FICO 500+, consistent deposits, and a need of at least about $10,000, with decisions in roughly 24–48 hours. It is the widest door when your credit is rebuilding or your business is young, though it carries a higher cost of capital than a bank product.
How fast can I actually get funded?
It depends on the source. Banks and SBA lenders typically take weeks to a couple of months. Lines of credit and equipment financing often fund in days. Revenue-based financing through a marketplace is usually the fastest, with decisions in about 24–48 hours once your bank statements are in.
Is a merchant cash advance the same as a loan?
Not exactly. Revenue-based financing, often called a merchant cash advance, is repaid as a share of future sales or a fixed remittance that flexes with your deposits, rather than a fixed loan payment. It's underwritten on revenue and bank activity instead of credit score, which makes it fast and forgiving on credit but higher in cost — best used for short, revenue-generating purposes.
What credit score do I need for a business loan?
It varies widely by source. Banks often want 680+, SBA loans and many fintech lenders sit in the mid-600s, and revenue-based marketplaces work with FICO 500+ because they weight deposits and revenue over score. Match your application to the source whose bar you actually clear rather than collecting declines from lenders out of your range.
Can I combine more than one funding type?
Yes, and it's often the smartest approach. For example, a business might use equipment financing for a specific machine and revenue-based working capital for an inventory build at the same time. Combining lets each product do the job it's built for instead of forcing one loan to cover unrelated needs. Just size the total against what your cash flow can carry.
How do lenders decide whether to approve me?
They weigh some mix of personal and business credit, time in business, revenue and its consistency, the cash flow visible in your bank statements, and any collateral. Banks lean hardest on credit and financials; equipment and invoice lenders lean on the asset; revenue-based marketplaces lean on your deposits and revenue. Keeping your bank account clean and your business finances separate improves your odds almost everywhere.
Should I be worried about 'guaranteed approval' offers?
Yes. No responsible funder can promise approval before reviewing your file, so treat 'guaranteed' language as a warning sign. A legitimate lender or marketplace will review your bank statements and revenue first and give you a real decision — fast, in the case of a revenue-based marketplace, but never guaranteed.
