Overview

Buying an existing business can speed time to market, provide an established customer base, and deliver immediate cash flow. But a misstep in financing or due diligence can turn opportunity into a costly mistake. This guide lays out practical financing options, explains how lenders and sellers evaluate deals, and gives a structured, professional due diligence checklist you can use during negotiations and closing.

Author’s note: In my 15+ years advising buyers, the most successful transactions combine a conservative financing mix and a disciplined, itemized due diligence process involving a CPA, business attorney, and lender early on.

Financing options: what buyers actually use

1) Bank term loans (traditional commercial loans)

  • What they are: Senior debt from banks secured by business assets or personal guarantees.
  • When they fit: Buyers with solid credit, sufficient collateral, and a clear pro forma showing debt service coverage.
  • Pros: Lower interest rates and longer terms than many alternatives.
  • Cons: Strict underwriting, collateral requirements, and often a need for supplemental capital.
  • Note: Many regional banks will require a business plan, historical financials, and personal guarantees.

2) SBA-guaranteed loans (SBA 7(a), SBA 504)

  • What they are: Loans partially guaranteed by the U.S. Small Business Administration to increase lender willingness to finance acquisitions.
  • Why they matter: SBA 7(a) is the most common choice for business acquisitions because it supports working capital and buyouts; SBA 504 focuses on fixed assets like real estate and equipment. (See SBA resources for program details: https://www.sba.gov.)
  • Pros: Lower down payment requirements and longer amortizations compared with many conventional loans.
  • Cons: Longer application timelines and detailed documentation requirements.

3) Seller financing (owner carryback)

  • What it is: The seller agrees to take a promissory note for part of the purchase price instead of receiving all cash at closing.
  • Why buyers like it: Reduces immediate cash needs and signals seller confidence in the business.
  • Key negotiation points: interest rate, amortization, prepayment penalties, security (e.g., UCC filing), and remedies for default.
  • Caution: Always verify seller disclosures independently; use your attorney to draft or review the note and security documents. See our seller financing primer: https://finhelp.io/glossary/seller-financing/.

4) Equity financing and private investors

  • What they are: Selling a portion of equity to investors, family offices, or private equity firms.
  • Pros: Access to capital without increasing debt; investors may bring strategic help.
  • Cons: Dilution of ownership and potential loss of control; investors will expect governance rights and exit strategy clarity.

5) Hybrid structures (seller note + bank loan, earnouts)

  • Many deals use combinations: an SBA loan for the bulk, a seller note to cover down payment shortfalls, and an earnout tied to future performance to bridge valuation gaps.

6) Alternative lenders, mezzanine, bridge loans

  • Shorter-term solutions that can bridge timing gaps during escrow or provide capital when traditional lenders decline. Expect higher costs and stricter covenants.

How lenders and sellers evaluate deals

  • Historical financials: Lenders and buyers will review at least 2–3 years of financial statements, tax returns, and cash flow statements.
  • Adjusted EBITDA or Seller’s Discretionary Earnings (SDE): Buyers evaluate normalized earnings and one‑time adjustments to determine sustainable cash flow and service debt.
  • Collateral and guarantees: Lenders look for tangible collateral and often require personal guarantees from buyers.
  • Industry risk and location: Lenders price risk by industry margins and local market trends.

Practical tip: Prepare a clear, conservative 12–24 month pro forma showing how you will cover debt service and working capital needs—this improves your credibility with lenders.

Due diligence: a step‑by‑step checklist (operational timeline for a typical 30–90 day acquisition)

Phase 1 — Initial review (days 1–7)

  • Letter of intent (LOI): Define price, key terms, confidentiality, exclusivity period, and major conditions (financing, due diligence, and approvals).
  • Preliminary documents requested: tax returns, P&L, balance sheets, major contracts, lease, and organizational chart.

Phase 2 — Financial & tax due diligence (days 8–30)

  • Tax returns and notices: Review last 3–5 years of business and owner tax returns; ask for any IRS notices or audits.
  • Reconcile book vs tax: Identify add-backs and normalize earnings (owner compensation, related-party transactions).
  • Accounts receivable and payable: Confirm aging, collectability, and any large, atypical customer concentrations.
  • Inventory: Count methods, valuation, obsolete inventory reserves, and liens.
  • Debt and contingent liabilities: Confirm all outstanding loans, guarantees, judgments, and pending litigation.
  • Working capital target: Negotiate a target in the purchase agreement and verify current levels.

Phase 3 — Legal and contract review (days 15–45)

  • Corporate documents: Articles, bylaws, minutes, ownership ledger, and stock transfer restrictions.
  • Contracts: Review customer contracts, supplier agreements, service contracts, non-competes, and NDAs for assignability and change‑of‑control provisions.
  • Employee matters: Offer letters, employment agreements, benefit plans, and payroll tax compliance; identify key employees and retention risks.
  • Real estate and leases: Examine lease terms, options to renew, subordination/consent clauses, and environmental liabilities.

Phase 4 — Operational, commercial, and HR (days 20–60)

  • Operations: SOPs, vendor lists, production capacity, and quality-control records.
  • Customers and churn: Verify top customers, revenue concentration, contract terms, and churn rates.
  • IT and IP: Confirm ownership of software, trademarks, domain names, and cybersecurity posture.
  • Insurance: Review policies and claims history; verify current coverage is transferrable or insurable post‑close.

Phase 5 — Final validation and closing prep (days 45–90)

  • Closing deliverables: Draft purchase agreement, seller note, security agreements, escrow instructions, and title or UCC searches.
  • Escrow and holdbacks: Negotiate holdbacks or escrows for indemnity claims and unknown liabilities.
  • Closing checklist: Make a list of items for closing—licenses, permits, bank account transfers, customer notifications, and employee onboarding steps.

Red flags that should change your offer or stop the deal

  • Unreconciled tax liabilities or repeated IRS notices.
  • Revenue concentrations where a few customers represent >30–40% of sales without contracts.
  • Nontransferable key contracts or missing vendor consents for assignment.
  • Rapid declines in gross margin without clear cause.
  • Environmental issues tied to property or operations.
  • Significant off‑balance sheet liabilities or undisclosed related‑party transactions.

If you find any of these, consult your attorney and accountant immediately. Many issues can be resolved with price adjustments, escrowed indemnity funds, or seller warranties—but some are deal killers.

Valuation and deal structure notes

  • Common valuation methods: multiple of EBITDA, discounted cash flow (DCF), and asset‑based valuations. For small owner‑operated businesses, Buyers often use Seller’s Discretionary Earnings (SDE).
  • Asset sale vs stock sale: Each has different tax consequences for buyer and seller. Buyers often prefer asset purchases to step up basis; sellers commonly prefer stock sales for tax efficiency. Discuss implications with a tax advisor before structuring.

Negotiation levers and protections

  • Earnouts: Tie a portion of the price to future performance to bridge valuation gaps.
  • Escrow/holdbacks: Protect buyer from undisclosed liabilities for a negotiated period (e.g., 6–24 months).
  • Representations & warranties, and indemnity provisions: Clearly define seller obligations and remedies for breaches.
  • Reps & Warranties Insurance: Consider for mid‑market deals to limit escrow size and accelerate seller proceeds.

Practical costs and timeline expectations

  • Typical timelines vary: a small cash transaction can close in 30 days; SBA‑backed or financed deals often require 60–90 days or longer for underwriting and approvals.
  • Professional fees: Expect legal, accounting, and advisory costs—often several thousand dollars for small deals and rising with complexity. Budget for third‑party reports (valuation, environmental, leases) as needed.

Post‑closing integration and risk management

  • Transition plan: Agree on seller involvement, training timelines, and customer introductions in writing.
  • Key employee retention: Provide retention bonuses or new offers to prevent attrition.
  • Monitor performance: Compare actuals to pro forma monthly for the first 12 months and address variance quickly.

Recommended team

  • Commercial lender familiar with acquisitions (ask early).
  • CPA experienced in business purchases and tax structuring.
  • M&A or business attorney to draft the purchase agreement.
  • Broker or M&A advisor (optional) for negotiation and market valuation.
  • Insurance broker to review coverage and advise on buyer policies.
