With a merger or acquisition, due diligence is the part you can’t just skip. It’s where the buyer digs deep, spots red flags, calculates the risk, and figures out if the deal is actually worth doing. Skip it or rush it, and you’re buying big trouble.
Buyers bring in lawyers, accountants, tax pros, and sometimes industry experts to tear through the target’s books and operations to see what they’re getting into. Here’s what they’re looking for:
Financial and Tax Compliance
Look hard at the numbers, revenue streams, cost structure, cash flow patterns, and seasonality. Are financials audited? Early-stage companies often skip audits, so you’ll need extra promises in writing of no hidden debt, receivables are real, etc.
The tax side is just as important. Can the deal be structured tax-free? If not, who’s paying the tax bill? Has the target been collecting and paying sales tax everywhere it should? Are there any research and development credits left on the table? Is the transfer pricing clean? If you miss any of these, the IRS surprise could come later.
Legal Review
Is the ownership clean? Consider stockholder agreements, old option plans, etc. All material contracts need to be read, including customer deals, vendor agreements, and leases. AI tools like Kira can speed this up, but humans still have to catch the termination clauses. Is the patent authentic, ensuring they are actually filed, trademarks renewed, open-source usage documented? Are there any lawsuits hiding in the shadows? If the business is regulated, double-check licenses and watch for antitrust (HSR) or foreign investment (CFIUS) filings.
Operational Deep Dive
How does the business actually run day-to-day? Supply chain weak spots, production bottlenecks, customer concentration risks. If you’re in the same industry, you’ll spot the gaps fast. This is also where you hunt for real synergies—overlapping customers you can cross-sell, costs you can smash together.
Tech and Cybersecurity Check
Buyers need to ensure how the business actually runs every day by examining workflow and discovering any efficiency bottlenecks. If you’re already in the same industry, you’ll spot the issues faster. The point is to find weak spots in supply chain, production problems, or capacity limits that could present themselves later.
Customer Reality Analysis
You also need to size up the customer base, market position, and who they’re really competing against. This is where you figure out if the two companies will actually fit together after closing, and where the big wins, or potential losses, are hiding. Talk to the biggest customers to test their loyalty or willingness to walk away. Are any contracts expiring that need to be renewed? This step enables growth upside and keeps revenue from walking away the day the deal closes.
Team Audit
Make sure everyone’s properly classified, whether they’re an employee or contractor. Are assignment agreements signed? Employment law clean? Map the organization’s chart, comp, and titles against your own so you can make fast, competitive offers. Flag the mission-critical people and consider making their new offer letters (or updated contracts) a closing condition.
Wrapping It Up
These are just some of the big areas to account for when performing due diligence. Real DD is meticulous, detail-obsessed work, but it’s the difference between a deal that creates value for years and one that deteriorates six months after closing. Do it right, and you rest easy at night. Cut corners, and it’ll turn into a nightmare.
