Short answer: When acquiring a service business, focus on whether revenue depends on the owner, a few clients, underpriced work, or staff that may not stay. The financial diligence should test revenue quality, gross margin, utilization, labor cost, customer concentration, working capital, and the first 100-day plan.
Service businesses can look simple because they often have limited inventory and tangible assets. The real value is in customers, people, reputation, processes, and repeatable delivery. Those are also the risks a buyer must test.

8 Financial Diligence Tips
- Separate recurring, project, and one-time revenue.
- Analyze customer concentration and contract transferability.
- Test gross margin by service line, client, and delivery model.
- Review utilization, staff cost, contractor dependence, and turnover.
- Identify owner-led sales, delivery, or client relationships.
- Normalize EBITDA with supportable add-backs only.
- Model working capital, deferred revenue, AR, and seasonality.
- Build a first-100-day plan before closing.
Service Business Diligence Table
| Area | Question | Evidence |
|---|---|---|
| Revenue | Is revenue repeatable or project-based? | Customer cohorts, contracts, pipeline, churn. |
| People | Will employees and key managers stay? | Org chart, compensation, retention, reviews, dependencies. |
| Margins | Are margins stable after true delivery cost? | Labor cost, contractor spend, utilization, pricing. |
| Working capital | Will the buyer need extra cash after closing? | AR aging, deferred revenue, AP, payroll timing. |
| Owner dependency | Can the business transfer? | Sales ownership, client relationships, process documentation. |
Owner Dependency Is Often The Deal Risk
In service businesses, the seller may be the rainmaker, client manager, recruiter, quality controller, and escalation point. If that role cannot transfer, price and structure need to reflect the risk.

Financials Need QoE Thinking
Adjusted EBITDA should be supported and connected to cash. Buyers should test add-backs, revenue recognition, deferred revenue, AR collectability, and normalized working capital. Alehar's QoE guide and M&A due diligence process explain the broader process.
When To Slow Down
- Revenue is highly concentrated and contracts are weak.
- Key employees are likely to leave.
- Margins depend on unpaid owner labor.
- AR is old or disputed.
- The seller cannot explain add-backs or revenue trends.
