How to Prepare for Due Diligence When Selling Your Business
Key Takeaways
- Due diligence is when a buyer verifies everything you've told them about the business
- Being organized and responsive builds buyer confidence — and protects your price
- Surprises in due diligence kill deals or trigger price reductions
- Most of the work happens before the LOI is signed, not after
You've received a signed Letter of Intent. The buyer is serious. Now comes due diligence — the period where they verify everything before they write the check.
This is where more deals fall apart than anywhere else. Not because of fraud — because of disorganization and surprises.
What buyers are actually looking for
Is the business what they said it was? Does financial performance match what was represented? Are the customer relationships real?
Are there hidden problems? Undisclosed lawsuits, tax issues, environmental liabilities, contracts with unfavorable terms, employees with no agreements.
Will this business work after the sale? Can key employees be retained? Will major customers stay?
What they'll ask for
Three years of tax returns and financial statements. Customer contracts and revenue breakdown. Lease agreements. Employee information and compensation. Equipment lists. Any pending litigation. Insurance policies. Licenses and permits.
How to prepare
Start organizing 6-12 months before going to market. Create a secure data room — a digital folder organized by category. Fix what you can. Disclose proactively what you can't fix. Respond to requests quickly and completely during the process.
During due diligence
Every day of delay gives the buyer more time to have second thoughts. Be honest — if something unfavorable comes up, address it directly. Buyers who feel managed or misled get suspicious, and once trust is gone it rarely comes back.
We prepare every client for due diligence before the first buyer conversation.
