Due Diligence
Investigation or audit of a potential deal or contract before signing.
While straightforward in theory, many businesses fail to actively track obligations tied to this concept - often resulting in missed deadlines, unintended renewals, penalties, or loss of contractual rights.
US Law · For business owners and foundersWhat is a Due Diligence?
Due diligence is the process of investigating and verifying information about a business, asset, or party before entering a contract or closing a transaction. The goal is to confirm that what the other side is representing is actually true - and to uncover anything they have not disclosed.
In contract law, due diligence matters because representations and warranties are only as useful as your ability to verify them. Thorough due diligence before signing gives you negotiating power, helps you price risk accurately, and builds the factual record you need if a dispute arises later.
In practice, many teams rely on a contract expiry tracking system to stay on top of dates and obligations tied to clauses like this.
Key Elements
Financial Due Diligence
Reviewing financial statements, tax returns, accounts receivable and payable, revenue trends, debt obligations, and cash flow. The goal is to confirm the financial picture matches what was represented in negotiations.Legal Due Diligence
Examining contracts, litigation history, intellectual property ownership, corporate structure, regulatory compliance, permits, and employment agreements. Any undisclosed lawsuit or contract obligation could become your problem after signing.Operational Due Diligence
Assessing the actual business operations - key personnel, customer concentration, supplier dependencies, technology systems, and processes. A business may look good on paper but be dangerously reliant on one customer or one person.Due Diligence Checklist and Data Room
In most deals, the seller populates a secure data room with requested documents. The buyer's advisors review the materials and raise questions. Any gaps or inconsistencies should be addressed before closing - not after.Representation and Warranty Insurance
In M&A transactions, buyers sometimes purchase rep and warranty insurance to cover losses arising from breaches discovered post-closing. This shifts some risk to an insurer rather than relying entirely on indemnification from the seller.Real-World Example
TechStart Inc. is acquiring a small SaaS company called Flowtrack for $3M. During due diligence, TechStart reviews Flowtrack's customer contracts and discovers that 60% of annual revenue comes from a single enterprise client whose contract expires in 90 days with no renewal commitment. Flowtrack's financials did not flag this concentration risk.
TechStart now has critical leverage. They can renegotiate the purchase price to reflect the revenue risk, require the customer contract to be renewed as a closing condition, or walk away entirely. Without due diligence, TechStart would have paid $3M for a business that could lose most of its revenue within months of closing. This is exactly what due diligence is designed to catch.
This is why many businesses adopt automated deadline tracking to ensure no critical dates are missed before they pass.

Due Diligence Condition Precedent (in an acquisition agreement)Watch Out For
Rushing due diligence to meet a deadline
Sellers often push for fast closings to limit the scope of scrutiny. Resist artificial timelines that force you to skip important review steps. A deal that closes fast and blows up later costs far more than a deal that takes an extra two weeks to close properly.Relying solely on representations and warranties
Reps and warranties give you a legal remedy if something turns out to be false. But pursuing that remedy requires time, money, and litigation. Due diligence lets you catch problems before they become your problem. Use both.Ignoring the other party's counterparties
A vendor's financial health depends on their suppliers and sub-contractors. A target company's value depends on the durability of its customer relationships. Do not just investigate the party you are contracting with - look at what their business depends on.Don't let due diligence deadlines catch you off guard
Key dates tied to due diligences - renewal windows, expiry cutoffs, notice periods - can easily slip through the cracks when tracked manually. Missing them triggers automatic extensions, penalties, or lost rights. ExpiryEdge tracks every critical deadline and sends automated reminders before they're due - so nothing slips.
Instead of relying on spreadsheets or manual follow-ups, a centralized renewal reminder system ensures every deadline is visible, tracked, and actioned automatically.
How to Use This in Your Favor
Create a standard due diligence checklist for recurring deal types
If your company regularly enters vendor agreements, partnerships, or acquisitions, build a repeatable due diligence checklist tailored to each deal type. A consistent process reduces the chance of missing something important.Use due diligence findings to negotiate better terms
Every risk you uncover during diligence is a potential price reduction, indemnification right, or closing condition. Document findings carefully and use them at the negotiating table rather than accepting the deal as-is.Request a data room early and track what is missing
Ask for the data room at the start of negotiations, not just before closing. Slow or incomplete document production can signal that the other side is hiding something. Track every request and every gap - that paper trail matters if a dispute arises.Related Terms
Frequently Asked Questions
Is due diligence legally required before signing a contract?
No, it is not a legal requirement. But skipping it can cost you dearly. Courts generally hold that sophisticated parties are expected to investigate before signing. If you overlook a problem that reasonable diligence would have caught, you may have limited recourse after the fact.
What is the difference between due diligence and an audit?
An audit is a formal examination of financial records by an independent accountant, usually conducted for reporting or compliance purposes. Due diligence is broader - it covers financials, legal, operational, and commercial matters, and is conducted specifically to inform a business decision like an acquisition or major contract.
Who pays for due diligence?
Typically the party conducting the investigation - the buyer or the party taking on risk. In large transactions, due diligence costs can run from tens of thousands to several million dollars in advisor fees. These costs are usually the buyer's expense unless the deal falls through due to seller breach.
What happens if I find a problem during due diligence?
You have options: renegotiate the price or terms to reflect the risk, require the seller to fix the problem before closing, add specific indemnification for the identified issue, or walk away. Finding problems during diligence is exactly what the process is for - it is far better than discovering the issue after signing.
