The seller seems nice. The business looks good on paper. The broker is pushing for a quick close.

Before you sign anything, you need answers. Real answers, not sales pitches.

This is the complete list of questions to ask before buying any service business—cleaning, HVAC, landscaping, or any other local service operation. Print this out. Bring it to every meeting. Don’t close until you have documented answers to every question.

Financial Questions (Ask First, Trust Nothing)

Revenue Verification

1. Can I see three years of complete federal tax returns, including all schedules?

Why it matters: Tax returns are filed under penalty of perjury. They’re the most reliable financial documents you’ll get. Internal financials can say anything.

2. Can I see 12-24 months of bank statements for all business accounts?

Why it matters: Bank deposits should match reported revenue within 5%. Large discrepancies indicate unreported cash, timing issues, or fraud.

3. Can I see 12 months of credit card processing statements?

Why it matters: Card transactions are independently verifiable. Compare to reported revenue for consistency.

4. What percentage of revenue is cash versus card/check/ACH?

Why it matters: Cash-heavy businesses (over 30%) are harder to verify and may have unreported income you can’t count on.

5. Can you break down revenue by customer for the past three years?

Why it matters: Reveals customer concentration, trends, and which relationships actually drive the business.

6. What is the monthly revenue pattern over the past 24 months?

Why it matters: Reveals seasonality, trends, and any recent changes that might not be obvious in annual numbers.

Expense Verification

7. Can you provide documentation for every add-back in your SDE calculation?

Why it matters: Unsupported add-backs are fabricated value. Every add-back should have receipts, invoices, or clear explanation.

8. What expenses will I definitely incur that you don’t currently have?

Why it matters: Owner may have relationships, grandfathered rates, or free help that won’t transfer to you.

9. Are there any expenses you’ve deferred that I should know about?

Why it matters: Deferred maintenance, needed equipment replacement, or upcoming repairs reduce actual value.

10. What are your actual costs for insurance, and when do policies renew?

Why it matters: Your rates may differ significantly, especially with no claims history in this business.

Cash Flow Reality

11. What is the average collection time for your accounts receivable?

Why it matters: If customers pay in 60-90 days, you need working capital to survive the gap.

12. Can I see the current accounts receivable aging report?

Why it matters: Old receivables (60+ days) often become bad debt. Don’t pay for uncollectible AR.

13. What deposits or prepayments do customers have with you?

Why it matters: You’ll owe those services without receiving the payment—a liability you’re inheriting.

14. Are there any outstanding liabilities not reflected on the balance sheet?

Why it matters: Verbal commitments, warranty obligations, or informal debts can surface after closing.

Customer Questions (Where the Value Actually Lives)

Customer Base Health

15. How many active customers do you have, and how do you define “active”?

Why it matters: “500 customers” might mean 500 people who used you once. Understand the real number.

16. What percentage of customers are recurring versus one-time?

Why it matters: Recurring customers are worth 5-10x one-time customers. This dramatically affects value.

17. What is your annual customer retention rate?

Why it matters: If 40% of customers leave each year, you’re constantly replacing revenue just to stay flat.

18. Who are your top 10 customers and what percentage of revenue does each represent?

Why it matters: If top customer is 25%+ of revenue, that’s dangerous concentration.

19. Have you lost any significant customers in the past 12 months? Why?

Why it matters: Recent losses might indicate problems. Understand the reasons.

20. Are any customers planning to leave or currently unhappy?

Why it matters: The seller knows. Don’t inherit churn that’s already in motion.

Customer Relationships

21. Do customers have written contracts, and can I see samples?

Why it matters: Contracts provide stability. Month-to-month means customers can leave instantly.

22. Are contracts assignable to a new owner, or do they require customer consent?

Why it matters: Some contracts have change-of-control provisions that let customers exit.

23. How did you acquire your customers originally?

Why it matters: Reveals whether customer acquisition is systematic or dependent on owner relationships.

24. Which customers have a personal relationship with you specifically?

Why it matters: These are highest flight risk when ownership changes. Plan accordingly.

25. Can I contact 10-15 customers during due diligence?

Why it matters: If seller won’t allow customer contact, something’s wrong. Real customers confirm the story.

Employee and Operations Questions (Who Actually Does the Work)

Workforce Structure

26. How many employees versus independent contractors do you have?

Why it matters: Contractor misclassification is a massive liability. Understand the structure.

27. For each 1099 contractor: Do they set their own hours? Use their own equipment? Work for other companies?

Why it matters: If contractors look like employees, you inherit IRS and state labor liability.

28. Can I see a complete employee roster with tenure, role, and compensation?

Why it matters: Understand who actually runs the business and what it costs to keep them.

29. Which employees are essential to operations, and will they stay after the sale?

Why it matters: Key employee departure can devastate a business post-acquisition.

30. What is your annual employee turnover rate?

Why it matters: High turnover (50%+ in service businesses is common but problematic) indicates management issues or pay problems.

31. Are any employees related to you?

Why it matters: Family members may leave with the seller. Understand dependencies.

Operational Knowledge

32. How many hours per week do you work in the business?

Why it matters: If owner works 60 hours, you’re buying a job, not a business. SDE assumes you’ll work those hours.

33. What do you do during those hours?

Why it matters: Understand what role you’ll need to fill or hire for.

34. What happens if you take a two-week vacation?

Why it matters: If the business stops, it’s owner-dependent. That reduces value and increases risk.

35. Is there an operations manual or documented processes?

Why it matters: Documentation means knowledge transfers with the sale. No documentation means knowledge walks out the door.

36. What software and systems do you use to run the business?

Why it matters: Understand what’s transferable, what has ongoing costs, and what you’ll need to replace.

Legal and Compliance Questions (Where Surprises Hide)

Business Structure

37. What is the legal structure (LLC, S-Corp, C-Corp, Sole Prop)?

Why it matters: Affects deal structure, liability, and tax implications.

38. Are all business licenses and permits current and transferable?

Why it matters: Some licenses don’t transfer—you may need to reapply, causing operational delays.

39. Has the business ever operated under different names?

Why it matters: Prior names may have liabilities or reputation issues you need to understand.

Litigation and Claims

40. Is there any current, pending, or threatened litigation?

Why it matters: Lawsuits survive ownership changes. Know what you’re inheriting.

41. Has there been any litigation in the past five years? What was the outcome?

Why it matters: Past issues indicate risk areas and potential repeat problems.

42. Have there been any workers’ compensation claims in the past three years?

Why it matters: Claims history affects your insurance rates and indicates safety issues.

43. Have there been any insurance claims in the past three years?

Why it matters: Claims history affects premiums and may indicate operational problems.

Compliance Status

44. Are there any outstanding tax obligations (federal, state, local)?

Why it matters: Tax liens can attach to business assets. Verify clean status.

45. Is the business current on all payroll taxes and filings?

Why it matters: Unpaid payroll taxes are personal liability for business owners.

46. Have there been any OSHA, EPA, or regulatory issues?

Why it matters: Violations can carry ongoing penalties and remediation requirements.

The Seller Questions (Why Are They Really Selling)

47. Why are you selling this business?

Why it matters: The most important question. Listen carefully for the real answer.

Common answers and what they might mean:

Follow-up questions:

• How long have you been planning to sell?
• Did you try to sell before? What happened?
• What would make you stay?
• What will you do after selling?

A seller who genuinely believes in the business will show it. Desperation, vagueness, or inconsistency indicates problems.

Questions to Ask Yourself

Before making an offer, honestly answer:

A. Can I verify every material fact independently?

If you’re relying on seller’s word for key facts, you don’t have enough information.

B. What happens if revenue drops 20% in year one?

Can you survive? Can you make debt payments? Have you stress-tested the numbers?

C. Am I the right operator for this business?

Do you have the skills, time, and interest to actually run this? Or are you buying a fantasy?

D. What’s my backup plan if this fails?

Every acquisition can fail. Understand your exposure and exit options.

E. Would I still buy this at 80% of the current price? At 120%?

If no to 120%, you’re at the edge of fair value. If yes to 80%, maybe offer that.

How to Use This Checklist

Before the First Meeting

Review this list. Understand what you need to know. Prioritize the financial and customer questions—these determine if the business is worth further investigation.

During Initial Conversations

Ask questions from this list directly. Take notes. Note which questions get clear answers and which get deflection.

During Due Diligence

Work through the complete list systematically. Request documentation for every answer. Verify independently where possible.

Before Signing

Review your notes. Are there unanswered questions? Unsupported claims? Red flags you’ve rationalized away?

If you don’t have documented, verified answers to at least 40 of these 47 questions, you’re not ready to close.

Red Flag Response Guide

The Bottom Line

Buying a business is not like buying a car. There’s no Carfax. There’s no lemon law. Once you close, you own every problem—known and unknown.

These 47 questions are your protection. They’re designed to surface problems before they become your problems.

Sellers who have good businesses welcome thorough questions. They have nothing to hide and understand that serious buyers do serious diligence.

Sellers who resist, deflect, or pressure you to skip steps are telling you something. Listen to what they’re not saying.

Take your time. Get every answer. Verify everything.

Or better yet—consider whether building from scratch might be the smarter path.

Thinking about starting fresh instead? See what it actually costs to build a service business from the ground up—no hidden problems, no inherited liabilities.

Frequently Asked Questions

How do I start a service business in 2026?

Start by choosing a service type based on demand, skills, and startup costs. Then register your business, get required licenses, purchase equipment, set up insurance, and begin marketing to your target customers.

What’s the most profitable service business to start?

Profitability depends on your market and execution. High-margin services include HVAC, plumbing, electrical, and specialized cleaning. Lower-cost startups like pressure washing and lawn care can also be highly profitable.

How much money do I need to start a service business?

Startup costs range from $5,000 for basic services (cleaning, lawn care) to $100,000+ for licensed trades (HVAC, plumbing). Many profitable businesses launch for $15,000-$30,000 with essential equipment and marketing.

Do I need experience to start a service business?

No, many successful owners started with zero experience. Learn through training, shadowing, and starting with simpler jobs. Business skills often matter more than technical expertise, which can be hired.

How long until a new business is profitable?

Most service businesses can be profitable within 3-6 months with consistent effort. Breaking even typically happens in 6-12 months. Building to full income replacement usually takes 12-24 months.

Should I buy a franchise or start independently?

Independent businesses offer more control and no royalty fees (5-8% ongoing). Franchises provide systems but limit flexibility. For most service businesses, independent ownership with proper guidance provides better returns.
