Legal Due Diligence Checklist: What Buyers Must Verify Before Closing on a Service Business

Hire a real M&A attorney — not your family lawyer

Your cousin who does real estate closings cannot draft an Asset Purchase Agreement. Hire an attorney who has personally closed at least 20 small-business acquisitions. Expected legal spend on a $1M–$5M deal: $12K–$30K for buyer-side counsel. It is the single best dollar you will spend in the transaction.

Asset sale vs stock sale — the $200K structural decision

Roughly 95% of service-business deals under $10M are structured as asset sales. As the buyer you get: a stepped-up tax basis (re-depreciating assets at the new purchase price), no inherited unknown liabilities, a fresh start with no historical lawsuits or tax exposure, and the ability to cherry-pick which contracts and employees come with the deal.

Sellers prefer stock sales because the gain is fully long-term capital gains at the personal level and they walk away from all liabilities. When a seller insists on stock, the buyer typically negotiates a purchase price 'gross-up' (a higher price to compensate for the seller's tax savings being smaller) plus expanded indemnification.

Special cases that force stock sales: state contractor licenses that do not transfer, key customer contracts with anti-assignment clauses, government contracts (8(a), GSA), and certain pest control / pharmacy / liquor licenses.

Contract review — the four categories that matter most

Customer contracts: review every contract above 5% of revenue for assignability, change-of-control, termination-for-convenience, and exclusivity clauses. Any contract requiring 'consent to assign' becomes a closing condition you must collect signed consents on before funding.

Supplier and vendor agreements: equipment leases, software (ServiceTitan, Housecall Pro), fuel contracts, and parts supplier MSAs all need assignment consent. Most are routine, but a missed software assignment can take dispatch offline on day one.

Real estate lease: pull an estoppel certificate from the landlord and a written consent to assignment. If the lease has less than 2 years remaining, negotiate an extension as a closing condition — your SBA lender will require it.

Employment, independent contractor, and non-compete agreements: confirm the agreements actually exist in writing and confirm whether non-competes legally transfer in your state (they generally do in asset sales, but only with proper assignment language).

Employment law landmines specific to service businesses

1099 misclassification is the single largest hidden liability in service-business M&A. Many HVAC, plumbing, landscaping, and cleaning companies pay technicians as 1099 contractors who are functionally W-2 employees under IRS and DOL tests. The buyer can inherit back payroll taxes, penalties, workers' comp gaps, and class-action wage claims.

Verify I-9 compliance for every employee. Pull an I-9 audit before closing and require the seller to cure any deficiencies pre-close at their cost.

Accrued PTO, sick leave, and commission liabilities transfer in most asset sales unless explicitly excluded. Calculate the dollar amount and either subtract it from purchase price or have the seller pay it out at closing.

Confirm workers' comp coverage is continuous through closing and that the new entity will be added to the policy or has a binder in place for day one.

Pending and threatened litigation

Run public records searches in every county the business has operated in for the past five years. Look for: customer lawsuits (warranty, slip-and-fall, property damage), EEOC and state civil rights complaints, wage-and-hour claims, vendor disputes, and tax liens.

Ask the seller in writing for a list of any threatened claims (demand letters, attorney correspondence, EEOC charges) that have not yet been filed. This becomes a representation in the APA — false statements here are how indemnification claims later get won.

Reps, warranties, indemnification, and escrow

Standard structure on a $1M–$5M deal: 10–15% of purchase price held in escrow for 12–18 months to backstop seller representations. Survival periods: 18–24 months for general reps, 3–7 years for tax and ERISA reps, indefinite for title and authority.

For deals above $2M enterprise value, consider Reps & Warranties Insurance (R&W) — premiums have dropped to roughly 3–4% of coverage limits and let you reduce escrow to 1% while expanding indemnification protection.

Always require a specific indemnification carve-out for 1099 misclassification, undisclosed liabilities, pre-close taxes, and license/permit issues. These are the four areas that produce 80% of post-close disputes.

IP, data, and customer list assignment

The customer list is often the most valuable asset in a service business. Make sure the APA explicitly assigns: the customer database, the company phone number (this is huge — a service company's primary phone number is the business), the domain name, social media accounts, Google Business Profile, online reviews, and all marketing materials.

If the seller built proprietary software, scripts, or training materials, get a written work-for-hire confirmation and an IP assignment from every developer or contributor.
