HR Due Diligence: People Questions to Ask Before You Buy a Business

By April, Live Oak HR Group · October 8, 2026

When you buy a business, you're buying its people, its pay practices, and its liabilities along with its revenue. Financial and legal due diligence get most of the attention. HR due diligence is where many expensive surprises hide.

Workforce basics

• Headcount, an org chart, and who reports to whom
• Which employees are classified as exempt and non-exempt, and whether those classifications hold up
• How many workers are independent contractors, and whether any should be employees
• Turnover over the past few years and the reasons people left

Pay and benefits

• Pay structures, recent raises, and any promised but unpaid bonuses or commissions
• Benefit plans, their costs, and how they compare to yours
• Accrued vacation or PTO that may need to be paid out
• Retirement plan obligations and any known plan issues

Contracts and obligations

• Employment agreements, especially for leaders and key staff
• Change-of-control, severance, or retention payments triggered by the sale
• Non-compete, non-solicitation, and confidentiality agreements, and whether they'll transfer

Compliance and risk

• Pending or recent employee claims, complaints, and investigations
• Wage and hour practices, including how overtime and breaks are handled
• Completed and current I-9 forms for all employees
• Safety records and any workplace injury claims

Culture and key people

Numbers tell you what you're buying. Culture tells you whether it will still work after closing. Find out who the business truly depends on, which of those people are likely to leave, and how the company makes decisions and handles conflict. Big differences in leadership style or ways of working are worth planning for before day one.

After closing: the first 100 days

1. Communicate early and honestly. Employees fill silence with rumors. Tell them what's changing, what isn't, and when they'll know more.
2. Secure key people. Retention agreements and real conversations with critical employees should happen right away.
3. Align pay, benefits, and policies on a clear timeline, explaining the reasons behind changes.
4. Settle the structure. Clarify roles, reporting lines, and decision-making so people know where they stand.
5. Handle any workforce reductions fairly and in line with notice requirements.
