Small Business Financing: The Complete Guide for Owners

What counts as small business financing

Small business financing covers any funding you use to cover expenses or grow. The most common forms are term loans, lines of credit, invoice factoring, and merchant cash advances. Each one prices risk differently, so the best choice depends on your situation.

Many owners seek financing every year. In the Federal Reserve's 2024 Small Business Credit Survey, 59% of employer firms said they had applied for financing or used personal funds in the prior year. The most common reasons were covering operating expenses (56%) and funding an expansion (46%).

The survey also shows that outcomes vary widely. Only 41% of applicants got all the money they sought, while 24% got none. Knowing your options improves your odds and lowers your cost.

Start with SBA and bank loans for the lowest cost

SBA and bank loans almost always cost the least, so start there if you have time. The SBA's 7(a) program guarantees loans up to $5 million through banks and credit unions. Its Microloan program lends up to $50,000, with an average loan near $13,000.

These loans carry the lowest rates but the slowest process. Approval can take weeks and needs strong credit, tax returns, and often collateral. If you can wait and you qualify, this is the cheapest money you will find. Already carrying one? Use our business loan payoff calculator to see how much an extra monthly payment saves in interest.

When a bank says no or the timeline is too long, the alternatives below fill the gap. They cost more but move faster. The rest of this guide helps you choose among them.

The decision framework: speed vs. cost vs. receivables

Choose your financing by answering three questions in order. First, how fast do you need the cash? Second, how much can you afford to pay in total? Third, do you have unpaid invoices from other businesses (B2B)?

If you have B2B receivables and want the lowest cost of the fast options, invoice factoring usually wins. You sell unpaid invoices for cash now and pay a factor fee. Model the fee against your invoice value with our invoice factoring calculator.

If you have no B2B invoices but need cash in days, a merchant cash advance is the fastest, though the most expensive. If you have decent credit and want a reusable, lower-cost cushion, a business line of credit beats both. The next sections break down each one.

When invoice factoring is the right call

Invoice factoring fits businesses that invoice other companies and wait 30 to 90 days to get paid. You sell those unpaid invoices to a factor for most of their value up front. When your customer pays, you get the rest minus a factor fee.

Factoring is cheaper than a merchant cash advance and nearly as fast. It also does not add debt, since you are selling an asset you already own — as long as the deal qualifies as a sale under GAAP rather than a secured loan. Your approval leans on your customers' credit, not just yours.

Run your invoice amount and fee through our invoice factoring calculator to see your true cost.

If you need to book the deal on your own books, see our guide on how to account for invoice factoring.

When a merchant cash advance makes sense (and its true cost)

A merchant cash advance (MCA) is the fastest option, often funding in one to two days. You get a lump sum and repay it from a slice of your daily card sales. It fits businesses with strong card revenue and no B2B invoices to factor.

An MCA is priced with a factor rate, not an interest rate, which hides the real cost. A 1.4 factor rate on $50,000 means you repay $70,000, no matter how fast you pay it off. Convert a factor rate into a true annualized cost with our factor rate calculator.

Model the full advance, including daily payments, with our merchant cash advance calculator. To see how it stacks up against a normal loan, read our merchant cash advance vs. loan comparison.

When a business line of credit wins

A business line of credit is the most flexible option and usually cheaper than an MCA. It works like a credit card: you draw what you need, pay interest only on that amount, and reuse it as you repay. This makes it ideal for uneven cash flow.

A line of credit rewards decent credit and some operating history. Rates and limits depend on your revenue and credit profile. Because you only pay for what you use, it beats a lump-sum advance for ongoing or unpredictable needs.

Size a draw and estimate your interest with our business line of credit calculator. If your need is one-time and urgent instead of ongoing, revisit the factoring or MCA options above.

The warning: MCA stacking and confessions of judgment

The biggest danger in fast financing is a merchant cash advance, and two features make it worse. The first is stacking: taking a second or third advance on top of an existing one. Each new advance takes another cut of your daily sales, and the payments can quickly outrun your revenue.

The second is a confession of judgment (COJ). This is a clause where you sign away your right to fight a lawsuit before any dispute exists. The FTC has sued MCA operators who used COJs to seize business owners' personal and business assets, in one case winning a $20.3 million judgment.

Before you sign any advance, read every clause and refuse a COJ. Watch for hidden upfront fees and personal guarantees the FTC has flagged as deceptive. If a contract is confusing, have a lawyer review it first.

Match the tool to your need

The right choice comes down to your answers on speed, cost, and receivables. Have B2B invoices? Start with factoring. Need cash in a day with no invoices? An MCA is fastest but priciest. Want a flexible, lower-cost cushion? Use a line of credit.

Whatever you choose, run the numbers before you commit. Each option looks different once you see the total cost, not just the payment. The calculators below let you compare all three side by side.

Start with the cheapest option you qualify for and have time to get. Move to faster, costlier options only when speed truly matters. That order protects your margins.
