TL;DR: Buying an existing business is not a shortcut. It is a process. Define your target criteria, build a pipeline, run structured diligence, finance in parallel with that diligence, and plan the first 90 days before you close. According to the U.S. Small Business Administration, the largest advantage of buying an existing business is an established customer base, defined operating expenses, and trained employees. The operators who close are the ones who follow a process.
Why buy instead of build
Starting from zero means building revenue from zero. Buying a profitable business means you own cash flow on day one.
That is the core trade. A startup demands time and capital with no guarantee of a working model. An existing business already has customers, systems, and a financial history you can verify. The question is not whether buying beats starting. It is whether you can execute the acquisition correctly.
Veterans understand this framing. You do not build a logistics system from scratch during a mission. You work with what exists and optimize from there.
Define your buy box first
A buy box is a written description of what you will and will not buy. It includes:
- Industry or sector (service, manufacturing, distribution, professional services)
- Revenue range and EBITDA floor
- Geography
- Owner involvement (how dependent is the business on the current owner)
- Deal size your capital can support
- Financing structure you intend to use
Without a buy box, you will waste months looking at everything and committing to nothing. Specificity is not a limitation. It is how you build deal flow that actually converts.
For operators pursuing entrepreneurship through acquisition (ETA), the buy box typically targets businesses with $500K to $3M in annual EBITDA. That is the lower-middle market, where seller financing is accessible and competition from institutional PE is lower. Search funds and traditional PE operate very differently in this segment, and knowing the difference shapes your targeting.
Find deal flow on purpose
Deals do not find you. You build a pipeline.
Primary sources include:
- Business brokers: Most listed deals below $5M go through brokers. Build relationships before you need them.
- BizBuySell and similar platforms: High volume, lower signal. Good for market intelligence and valuation benchmarks.
- Direct outreach: Contact owners of businesses you want, not businesses for sale. Many of the best deals are not listed.
- Referral networks: CPAs, attorneys, and lenders who work with small business owners see transactions before they go public.
Expect to evaluate 50 to 100 opportunities to find one worth pursuing seriously. That is not failure. That is how the math works.
Evaluate fast, move deliberately
The first conversation with a seller or broker has one goal: determine whether this is worth your diligence budget.
Ask for three years of tax returns, a current profit and loss statement, and an add-back schedule. Add-backs are expenses the current owner runs through the business that a new owner would not carry. They adjust stated earnings toward actual earning power, called Seller's Discretionary Earnings (SDE) or EBITDA depending on deal size.
Red flags at this stage: financials that do not match across documents, declining revenue without a clear explanation, and heavy owner dependency with no transition plan.
If the numbers hold up on first review, move to a letter of intent. Do not spend money on formal diligence before an LOI is signed.
The letter of intent sets the terms of the deal
The LOI is not a formality. It is where you establish control of the transaction.
A solid LOI includes:
- Purchase price and payment structure (cash at close, seller note, earnout if applicable)
- Asset purchase versus stock purchase designation
- Exclusivity period (the seller agrees not to negotiate with other buyers while you run diligence)
- Key contingencies: financing approval, satisfactory diligence, lease transfer
- Timeline and closing target
Exclusivity matters. If you are spending 60 to 90 days on diligence and financing, you need protection against the seller shopping the deal while you work. Negotiate for it before signing anything.
Due diligence: verify everything
Diligence is not a document review. It is a structured verification process across four areas.
Financial: Confirm revenue and expenses against bank statements and payment processor records. Reconcile to tax returns. Understand add-backs and whether they are defensible. For deals above $2M EBITDA, commission a Quality of Earnings (QoE) report from an accounting firm.
Legal: Review all contracts (customer, vendor, lease). Check for litigation, pending claims, and compliance gaps. Confirm IP ownership and any transfer restrictions on key agreements.
Operational: Map the business to its owner. What happens if the current owner leaves on day one? Identify key employees, key customers, and key supplier relationships that need to be preserved.
Market: Assess customer concentration. If one customer represents more than 20% of revenue, that is a material risk that belongs in your pricing and deal structure. Understand competitive dynamics and any macro trends affecting the sector.
Diligence typically runs 30 to 90 days from LOI. According to CT Acquisitions, the average LOI-to-close timeline is 60 to 120 days depending on financing and deal complexity.
Financing: run it in parallel, not after
Most buyers secure financing after LOI. Most experienced buyers pre-qualify before they start searching.
The main financing options for buying an existing business:
SBA 7(a) loan: The most common vehicle for small business acquisitions. The SBA allows financing up to $5 million with down payments as low as 10 to 20 percent. Rates are typically prime plus 2 to 3 percent. The lender requires you to actively manage the business. Passive ownership disqualifies you.
Seller financing: The seller takes a portion of the purchase price as a note, paid over 3 to 7 years. This reduces your cash requirement at close and keeps the seller motivated during transition. It is more common than most first-time buyers expect, particularly in deals below $5M.
SBA loan plus seller note: A hybrid structure. The SBA loan covers the bulk of the purchase price, and the seller carries a subordinated note to bridge the gap. This can reduce the required down payment to 10 percent or less on the buyer's side.
The key discipline: involve your lender during diligence, not after. Late financing rejection kills deals that diligence already approved.
Closing the deal
Closing is execution, not ceremony.
Before funds transfer, run a closing checklist:
- All closing conditions satisfied (financing commitment, diligence sign-off, lease transfer approved)
- Asset schedules reconciled and signed
- Software access, vendor credentials, and customer records transferred
- Payroll system set up under new ownership
- Employee communication executed
- Seller's post-close transition role documented in the agreement
Deals fail at closing from missed details, not misaligned strategy. Run the checklist. Confirm every item before releasing funds.
The first 90 days determine the outcome
Closing is the beginning, not the finish line.
The first 90 days set the trajectory for everything that follows. Priorities:
- Meet the top five customers personally within 30 days
- Stabilize key employees: communicate clearly, address uncertainty fast
- Do not change pricing, operations, or branding in the first 60 days unless there is a genuine crisis
- Learn the business before you optimize it
- Execute one operational improvement in the first 90 days to build credibility with the team
EOD doctrine applies here. Identify the threat, clear the area, make the call. In business acquisition, the threat in the first 90 days is customer churn and employee attrition. Address both with direct, specific communication. The rest can wait.
Why veteran operators close more deals
Buying an existing business requires operating under incomplete information, making decisions with real consequences, and leading a team through change. Veterans train for all three.
The discipline gap in civilian M&A is not financial sophistication. It is process adherence under pressure. Most buyers collapse their diligence timelines when they fall in love with a deal. They skip steps. They accept the seller's narrative instead of verifying it.
Veterans verify. That is the edge.
At Patriot Growth Capital, we look for operator-led acquisitions in the lower-middle market: businesses with $1M to $10M in EBITDA, durable cash flow, and an owner ready to transition. Our Acquire, Mentor, Invest model pairs capital with operator accountability. 5 percent of our revenue funds the veteran community. The work and the mission are the same thing.
If you are considering buying an existing business and want a partner who understands both the deal mechanics and the operational execution, that is what we do.
Frequently Asked Questions
How long does it take to buy an existing business?
Most acquisitions take 3 to 12 months from first search to closing. The LOI-to-close phase alone typically runs 60 to 120 days, driven by financing timelines, diligence scope, and any lease or permit transfer requirements. SBA-financed deals tend to run longer than cash deals.
What is the typical down payment when buying a business with an SBA loan?
SBA 7(a) loans typically require a 10 to 20 percent down payment on the purchase price. In some cases, seller financing can cover part or all of that requirement, reducing the buyer's equity injection at close. Lenders also require post-closing liquidity as a reserve.
What is seller financing and how common is it?
Seller financing means the seller accepts a promissory note for part of the purchase price, paid over 3 to 7 years with agreed interest. It is common in small business deals below $5 million and signals that the seller is confident in the business continuing to perform. It also reduces friction in deals where bank financing does not cover the full gap.
What is the biggest risk when buying an existing business?
Owner dependence is the most common hidden risk. If the business runs on the current owner's relationships, technical skills, or personal brand, removing that owner disrupts revenue before you can stabilize it. Identify this during diligence by mapping which customers, suppliers, and employees are tied to the individual rather than the business.
