Why Buy an Existing Business Instead of Starting One?
An existing business with 3 years of profitable operating history is fundamentally less risky than a startup. The concept is proven. Customers exist. Employees are trained. The SBA knows this — and it's why SBA 7(a) lenders favor acquisitions over startup loans.
Advantages of buying vs. starting:
- Immediate cash flow from Day 1 — no 18-month runway to break-even
- Existing customer relationships and supplier accounts
- Trained employees who know the business
- Established brand, reputation, and local presence
- Easier SBA and bank financing (2+ years of operating history required)
- Lower failure risk in years 1–5 vs. startups
Tradeoffs of buying vs. starting:
- Higher upfront cost than a startup
- You inherit existing problems — culture, liabilities, deferred maintenance
- Key employees may leave post-acquisition if they were loyal to the prior owner
- Customer concentration risk — top clients may have been personal relationships
- Lease and contract obligations transfer with the business
The 7-Step Business Acquisition Process
Define your acquisition criteria
Before searching, define: industry (ideally with relevant experience), geographic area, revenue range, seller asking price budget (know your SBA down payment capacity), and non-negotiables (customer concentration limits, minimum years in business, staffed vs. owner-operated). Buyers without criteria waste months on deals that will never close.
Find businesses for sale
BizBuySell.com — largest online business-for-sale marketplace in the US. Filter by industry, revenue, and geography. Listings are typically priced already and represented by brokers. BizQuest.com and BusinessesForSale.com — additional inventory. Business brokers — most businesses sold under $5M are represented by brokers; engage a buyer's broker (often free to buyer — seller pays commission) to access unlisted deals. Direct outreach — identify businesses in your target industry and geography; send a letter of interest directly to the owner. Many businesses sell off-market. Industry associations — acquisition opportunities surface through trade association networks before public listing.
Evaluate and screen candidates
Review the seller's summary (typically includes 3 years of financials and a business overview). Screen for: consistent positive cash flow, acceptable customer concentration (no one client over 25–30%), manageable lease terms remaining, clear reason for sale (retirement vs. problems), and initial SDE/price multiple check against industry benchmarks. Narrow to 3–5 serious candidates before spending time on full due diligence.
Sign an NDA and receive confidential information
Sellers share financials under NDA (non-disclosure agreement). Standard NDA provisions: you won't share the information, won't contact employees or customers without permission, won't use the information to compete, and the NDA expires after 1–3 years. Sign and return promptly — sellers won't release detailed financials without it.
Submit a letter of intent (LOI)
If financial review confirms interest, submit an LOI outlining proposed price, deal structure, due diligence period, exclusivity request, and contingencies. The LOI is mostly non-binding but signals serious intent. It begins the exclusivity period during which the seller stops marketing the business. Key LOI terms are detailed in the next section.
Conduct due diligence
The 30–60 day period after LOI signing in which you verify everything the seller has represented. Financial, legal, HR, operational, tax, customer, and equipment due diligence. This is where most deals die — and where most price adjustments happen. Use the due diligence checklist below as your starting framework and expand based on industry specifics. Engage your CPA and an M&A attorney at this stage.
Negotiate purchase agreement and close
After satisfactory due diligence, execute the purchase agreement (also called an Asset Purchase Agreement or APA for asset sales, or Stock Purchase Agreement for stock sales). Simultaneously finalize SBA loan approval if applicable. Closing typically takes 30–60 days after purchase agreement execution. Transfer licenses, notify key clients and employees, complete SBA loan disbursement, and take possession.
Letter of Intent (LOI) — Key Provisions
| LOI Section | What It Covers | Typical Range |
|---|---|---|
| Purchase price | Total consideration — all-cash, SBA note, seller note mix | As negotiated |
| Earnest money deposit | Good-faith deposit held in escrow; returned if deal fails due diligence | $5,000–$50,000 |
| Due diligence period | Number of days buyer has exclusive access to records | 30–60 days |
| Exclusivity | Seller cannot market to other buyers during due diligence (binding) | 30–60 days |
| Financing contingency | Deal terminates if buyer cannot secure SBA or other financing | Standard |
| Due diligence contingency | Deal terminates if due diligence reveals material adverse information | Standard |
| Seller non-compete | Geographic and time restrictions preventing seller from competing | 3–5 years, 25–100 mile radius typical |
| Seller transition/training | Months seller stays to train buyer post-close | 30–90 days (often paid or included in price) |
| Earnout provision | Additional payment if business hits post-close revenue targets | 5–20% of purchase price; 12–36 month measurement period |
| Asset vs. stock structure | Whether deal is structured as asset sale or stock/interest sale | Negotiated; see exit planning guide |

SBA 7(a) Acquisition Financing — Buyer Requirements
Most small business acquisitions under $5M are financed using SBA 7(a). Here is what you need:
- Credit score: 680+ FICO (some SBA Preferred Lenders accept 660+)
- Down payment: Typically 10–15% of purchase price from verified personal funds (not borrowed)
- Industry/management experience: Relevant experience is required. SBA lenders want to see that you can run this type of business — either direct industry experience or equivalent management experience
- Personal financial statement: Net worth, assets, and liabilities. No material adverse financial condition that suggests inability to guarantee the loan
- Personal guarantee: All 20%+ owners of the acquiring entity must personally guarantee the SBA loan
- Post-acquisition DSCR: Your CPA and the SBA lender will model the business's cash flow after acquisition debt service — must exceed 1.25× to qualify
- Equity injection documentation: Bank statements showing 60 days of down payment funds in your account — SBA does not allow borrowed down payments
7 Acquisition Mistakes That Kill Deals or Destroy Returns
- Buying a job, not a business. If the business requires 60-hour weeks from the owner, and you're paying 3× SDE for the privilege — you bought a job with debt attached. Pay for businesses where the operations can run without the owner's constant presence.
- Skipping the CPA review of financials. Many small businesses have clean-looking P&Ls that fall apart under CPA scrutiny — personal expenses mixed with business expenses, revenue recognized incorrectly, or cash transactions not fully recorded. Your CPA's job in due diligence is to find the holes.
- Not getting an IRS tax transcript. The seller's P&L is internally prepared. The IRS tax return is filed under penalty of perjury. Form 4506-C gets you the IRS transcript — request it before closing. Discrepancies between the two are a major red flag.
- Assuming key employees will stay. The two people who run day-to-day operations may have no loyalty to you — they had loyalty to the prior owner. Ask about employment contracts, comp packages, and their plans. Have retention conversations before closing, not after.
- Ignoring lease risk. A business with 8 months remaining on its lease and no guaranteed renewal option has a major contingent liability. The landlord can demand a new lease at significantly higher rates as a condition of consenting to the assignment. Check the lease before you sign the LOI.
- Not modeling post-acquisition cash flow independently. Build your own post-acquisition cash flow model — don't rely on the seller's projections. Model debt service on your SBA loan, the seller note, any capital expenditures needed in year 1, and the impact of losing any clients you expect may not transfer. Run your model at 80% of the seller's claimed revenue.
- Buying without an M&A attorney. A business acquisition involves a purchase agreement, asset allocation (critical for taxes), assignment of leases and contracts, UCC lien releases, IP transfer, employment matters, and SBA closing requirements. Your real estate attorney, business attorney who doesn't specialize in acquisitions, or worse — no attorney — will cost you far more in errors than a qualified M&A attorney's fees.
Frequently Asked Questions
- Why buy an existing business instead of starting one?
- An existing business offers immediate cash flow, an established customer base, trained employees, a proven business model, and significantly easier access to SBA and bank financing. SBA lenders strongly prefer businesses with 2+ years of operating history over startups because the risk profile is materially lower. Tradeoffs: higher purchase price than a startup, inheriting the previous owner's problems, and potential risk of customer or employee attrition post-acquisition. Despite the higher entry cost, existing profitable businesses in established industries have substantially lower failure rates in years 1–5 vs. startups.
- How does SBA 7(a) financing work for buying a business?
- SBA 7(a) is the dominant financing tool for small business acquisitions under $5M. Structure: buyer puts 10–15% down (verified personal funds, not borrowed); SBA 7(a) finances the remainder, sometimes with a seller note of 10–20% placed on standby. Buyer requirements: 680+ FICO, relevant industry or management experience, personal guarantee, clean credit. Business requirements: 2+ years profitable operating history, clean books, DSCR 1.25×+ post-acquisition (modeled with the new debt service). SBA requires a business appraisal by a credentialed valuator for acquisitions over $250,000. Timeline: 45–90 days from complete application to closing.
- What is a letter of intent (LOI) when buying a business?
- An LOI is a mostly non-binding document outlining the proposed key terms of an acquisition: purchase price, deal structure (asset vs. stock sale), due diligence period (30–60 days), exclusivity (preventing the seller from marketing to other buyers during due diligence — this provision is binding), contingencies (financing, satisfactory due diligence), earnest money deposit ($5,000–$50,000), seller non-compete terms, and transition period. The LOI comes before due diligence and is replaced by the purchase agreement at close. Have an M&A attorney review before signing.
