The Small Business M&A Process, Step by Step

A step-by-step walkthrough of the small business M&A process, from first conversation and valuation through due diligence, financing, and closing.

Small business M&A can feel opaque from the outside, especially compared to the well-worn path of buying a house. In reality, most small business deals follow a fairly consistent sequence of steps, even though the details and timeline vary by deal. Here's what the process generally looks like from both a buyer's and seller's perspective.

1. Preparation

Sellers typically spend months (ideally a year or more) preparing before going to market: cleaning up financial statements, addressing customer concentration, documenting processes, and sometimes getting a preliminary valuation. Buyers prepare by getting clear on their budget, financing options, and the type of business and industry they're targeting.

2. Marketing and search

Sellers, often working with a business broker, create marketing materials (sometimes called a confidential information memorandum) and quietly market the business to prospective buyers, usually under a nondisclosure agreement to protect confidentiality from employees, customers, and competitors. Buyers search listings, work with brokers, or network directly to find businesses that match their criteria.

3. Initial conversations and screening

Interested buyers review basic financial information and ask questions in early calls. Sellers screen buyers for seriousness and financial capacity. This stage is about mutual fit before either party invests significant time.

4. Letter of intent (LOI)

Once a buyer and seller agree on the broad strokes -- price, structure, timeline -- they typically sign a letter of intent. An LOI is usually non-binding on price and terms but often includes binding confidentiality and exclusivity provisions, meaning the seller agrees not to negotiate with other buyers for a defined period while the buyer completes due diligence.

5. Due diligence

This is typically the longest and most detailed phase. The buyer (often with an accountant and attorney) reviews financial statements and tax returns, contracts, leases, employee records, licenses, litigation history, and operational details to verify what was represented and uncover any issues before closing.

6. Financing

If the buyer is using acquisition financing, most commonly an SBA loan, this typically runs in parallel with due diligence. Lenders will want their own review of the business's financials, the buyer's background, and often a business valuation or appraisal.

7. Definitive purchase agreement

Once due diligence and financing are substantially complete, the parties negotiate and sign the definitive agreement -- typically an asset purchase agreement or, less commonly for small deals, a stock purchase agreement -- covering the final price, structure, representations and warranties, and closing conditions.

8. Closing and transition

At closing, funds are transferred, ownership changes hands, and the parties execute any ancillary documents (bills of sale, assignment of leases, employment or consulting agreements for a transition period). Many deals include a transition period where the seller stays on briefly to introduce the buyer to customers and staff and transfer institutional knowledge.

How long does it take?

Timelines vary considerably, but a typical small business deal from initial marketing to closing often runs somewhere in the range of six months to a year. Deals with SBA financing, complex due diligence findings, or real estate involved tend to run longer. Patience and realistic expectations on timeline help both sides avoid unnecessary frustration.
