Buying a small business comes down to five things: confirm the business actually earns what the seller claims, agree on a fair price tied to real cash flow, structure the deal so risk is shared, line up funding to close, and keep enough working capital to survive the first 90 days of ownership. Most first-time buyers get the first four roughly right and run out of cash on the fifth. The businesses that make good targets are the ones where the money is verifiable in the bank statements — not the tax return, not the seller's spreadsheet, but the actual deposits. If you can read a deposit history, you can buy a business intelligently, and you can fund it the same way a lender or a revenue-based funder underwrites it: on the cash that moves through the account.
Key takeaways
- Bank deposits are the most reliable proof of a business's real earnings — verify them against merchant statements and tax returns before agreeing on price.
- Main Street businesses typically sell for about 2x to 4x Seller's Discretionary Earnings (SDE), adjusted for industry, growth, and owner dependence.
- Buyers need two cash pools: a down payment on the price and a separate working-capital reserve for the first 90 days of ownership.
- Revenue-based / MCA marketplace funding is underwritten on bank deposits and revenue (not credit score), accepts FICO 500+, starts around $10,000, and can fund in 24-48 hours.
- Seller financing keeps the seller invested in the outcome and is a positive signal about the business's staying power.
- No legitimate funder guarantees approval — it always depends on what the business's bank statements and revenue show.
- Revenue-based capital fits transition/bridge working capital, not financing the entire purchase price.
What "buying a business" actually requires (the short version)
An acquisition is a sequence, not an event. Skipping a step is how buyers overpay or inherit problems they can't see. In order:
- Find and screen. Identify a business in an industry you understand, in a size range you can afford, with an owner who has a real reason to sell (retirement, relocation, burnout — not "the market's about to turn").
- Sign an LOI and NDA. A non-binding letter of intent sets price, structure, and an exclusivity window so you can dig in without the seller shopping your offer.
- Do due diligence. Verify revenue, margins, customer concentration, contracts, leases, licenses, and liabilities. This is where the real work lives.
- Agree on structure. Asset purchase vs. stock purchase, seller financing, earnouts, working-capital adjustments, and non-compete terms.
- Fund and close. Combine your down payment, seller financing, and outside capital, then transfer ownership and — critically — keep a working-capital reserve for the transition.
The buyers who close cleanly treat due diligence and financing as one conversation. The way a business proves its value to you is the same way it proves it to a lender: consistent, bankable revenue.
Due diligence: verify cash, not stories
The single most important document in any small-business purchase is the last 12 to 24 months of business bank statements. Tax returns are optimized to look small. Seller "add-backs" are optimized to look big. Bank deposits are the least-lie-able number in the file. Reconcile three things against each other:
- Bank deposits — actual money received, month by month.
- Merchant / POS statements — card volume, which should track deposits for a retail or restaurant business.
- Tax returns and P&L — the story the seller tells the IRS and tells you.
When those three roughly agree, you have a real business. When deposits are far higher than reported revenue, ask why (and be skeptical of "cash we didn't report" — you can't buy or bank income that isn't documented). When they're far lower, the add-backs are fiction. Also pressure-test customer concentration (one client at 40% of revenue is a hidden risk), lease transferability, owner dependence (does revenue walk out the door with the seller?), and any liens or back taxes attached to the assets.

Valuation and price: what a small business is worth
Most Main Street businesses (under roughly $1M in earnings) trade on a multiple of SDE — Seller's Discretionary Earnings: net profit plus the owner's salary, plus legitimate one-time or personal expenses added back. Typical Main Street ranges run about 2x to 4x SDE depending on industry, growth, and how transferable the business is. A business that runs without the owner earns a higher multiple than one that is the owner.
Two guardrails keep buyers out of trouble. First, the price has to be serviceable by the cash flow — after you pay yourself a market wage and cover all debt payments, the business should still breathe. Second, scrutinize the add-backs. A seller who adds back health insurance, a personal vehicle, and "consulting fees" to a family member is inflating SDE to justify the price. Accept add-backs that are genuinely discretionary and truly won't recur under your ownership; reject the rest.
Example acquisition scenarios (illustrative)
These are illustrative figures to show how the same buyer profile changes across deal types — not quotes or offers. Every real deal is underwritten on its own numbers.
| Scenario (for example) | Annual revenue | SDE | Typical multiple | Common deal structure |
|---|---|---|---|---|
| Neighborhood restaurant | ~$900,000 | ~$150,000 | ~2x–2.5x | Down payment + seller note; buyer keeps a cash reserve for slow season |
| HVAC / home-services company | ~$1.4M | ~$320,000 | ~3x–3.5x | Bank/SBA-style loan + seller financing + earnout on retained crews |
| E-commerce / online store | ~$600,000 | ~$130,000 | ~2.5x–3x | Down payment + seller note; working capital funded on deposit history |
| Landscaping / route business | ~$500,000 | ~$110,000 | ~2x–3x | Down payment + seller note tied to customer retention |
Notice the pattern: in every case the buyer needs cash beyond the purchase price — for payroll, inventory, and the transition. That gap is where financing decisions are won or lost.
How buyers fund a small-business purchase
Almost no one buys a business with a single source of money. A typical stack combines several layers:
- Buyer down payment / equity — your own cash, usually a meaningful share of the price. Skin in the game.
- Seller financing — the seller carries a note for part of the price, paid back from the business's cash flow. This is powerful: a seller willing to finance is telling you they believe the business will keep earning.
- Term loan (bank or SBA-style) — the lowest cost of capital, but the slowest and most paperwork-heavy, and often contingent on collateral and strong personal credit.
- Revenue-based working capital — funding underwritten on the business's bank deposits and revenue rather than credit score, used to cover the transition, payroll, inventory, or a small gap in the purchase.
The layer buyers underestimate is the last one. A term loan pays the seller; it rarely leaves you a cushion. If you take over on the first of the month and payroll hits on the fifth, you need cash now — before the business's own receipts start landing in your account. For a fuller breakdown of the options, see our pillar guide on small business loans and financing options.
When revenue-based funding fits — and when it doesn't
Revenue-based capital (a revenue-based advance or MCA-style marketplace product) is approved primarily on the business's bank deposits and monthly revenue, not your personal credit. It reads the same deposit history you used in due diligence. That makes it a natural fit for acquisition buyers in specific situations, and a poor fit in others.
Works best when:
- The business you're buying already has steady, verifiable deposits — the underwriting is built on exactly that.
- You need working capital fast to cover the transition — payroll, rent, inventory, or a supplier who needs paying before your first receipts clear. Funding commonly lands in 24–48 hours.
- Your personal credit is thin or bruised (FICO in the 500s and up can still qualify) but the business's revenue is strong.
- You need a bridge alongside slower bank or seller financing, not a replacement for it.
Avoid or think twice when:
- You're trying to finance the entire purchase price this way — it's working capital and short-term bridge money, not a substitute for a full acquisition loan.
- The target's margins are thin and can't comfortably absorb a regular remittance out of daily or weekly cash flow.
- You have time and strong credit and a lower-cost term loan will fully cover both the price and a reserve.
The right funder here is a revenue-based / MCA marketplace that underwrites on deposits and revenue, typically starts around $10,000 minimum, accepts FICO 500+, and can fund in 24–48 hours. No legitimate funder "guarantees" approval — anyone who does is a red flag. Approval always depends on what the bank statements show.
A buyer's decision framework
Before you sign, run the deal through four questions in order. If any answer is a hard no, stop and renegotiate or walk.
- Does the cash verify? Do bank deposits, merchant statements, and tax returns tell the same story? If not, the price is fiction.
- Can the cash flow service the deal? After a market wage for you and every debt payment, does the business still have room to breathe? Build in margin for a bad month.
- Is the deal structured to share risk? Is the seller carrying a note or standing behind an earnout? A seller with zero ongoing exposure is a warning sign.
- Do you have a working-capital reserve? Beyond the purchase price, is there cash — yours or funded on the business's revenue — to survive the first 90 days? This is the step that quietly sinks otherwise good acquisitions.
Get all four to yes and you're not gambling — you're underwriting. That's exactly how professional buyers and lenders look at the same deal.
Frequently asked questions
How much cash do I need to buy a small business?
Plan for two separate pools of cash: a down payment on the purchase price (often a meaningful share, with the rest covered by seller financing and outside loans) and a working-capital reserve for the transition. The reserve is the one buyers forget — you need money for payroll, rent, and inventory before the business's own receipts start landing in your account. Revenue-based working capital, underwritten on the business's deposits, is commonly used to fund that gap when a term loan only covers the price.
What's the most important thing to check in due diligence?
The last 12 to 24 months of business bank statements. Deposits are the hardest number to fake. Reconcile them against merchant/POS statements and the tax returns — when all three roughly agree, the revenue is real. Large gaps in either direction mean the story doesn't hold, and that's a price or a walk-away conversation.
How are small businesses valued?
Most Main Street businesses trade on a multiple of Seller's Discretionary Earnings (SDE) — net profit plus the owner's pay and legitimate one-time or personal add-backs. Typical ranges run about 2x to 4x SDE depending on industry, growth, and how much the business depends on the current owner. Scrutinize the add-backs closely; inflated ones are the most common way a price gets padded.
Should I use an asset purchase or a stock purchase?
Most small-business buyers prefer an asset purchase because you acquire specific assets and generally leave behind the seller's undisclosed liabilities and legal history. Stock purchases can make sense when contracts, licenses, or permits are hard to transfer and are tied to the entity itself. This is a decision to make with an attorney and CPA — the tax and liability consequences are significant.
Can I get financing to buy a business with bad personal credit?
Sometimes, yes — it depends on which source you use. Bank and SBA-style term loans lean heavily on personal credit and collateral. Revenue-based funding is underwritten mainly on the business's bank deposits and revenue, so it can work with FICO in the 500s and up when the target business shows strong, steady cash flow. No funder can guarantee approval; it always comes down to what the deposits show.
How fast can I get working capital to close or cover the transition?
A revenue-based advance or MCA-marketplace product can often fund in 24 to 48 hours because the underwriting reads bank statements rather than waiting on a full credit and collateral review. That speed is why buyers use it as a bridge for payroll and inventory during the handover, alongside slower bank or seller financing rather than as a replacement for them.
Why does seller financing matter so much?
When a seller agrees to carry part of the price as a note, they're keeping financial skin in the game — they only get fully paid if the business keeps performing under you. That aligns incentives and is a strong signal the seller believes in the numbers. A seller who insists on all cash up front and no ongoing exposure is worth a harder look.
What's the minimum amount of revenue-based funding I can get for an acquisition?
Revenue-based / MCA marketplace funding typically starts around a $10,000 minimum and scales with the business's monthly deposits. It's designed for working capital and short-term bridges — the transition period, payroll, inventory, or a small gap in the purchase — not to finance an entire purchase price on its own.
