What does a forensic accountant do in a business purchase?

Most accountants check whether records are consistent. A forensic accountant asks why they are not, and follows the money until there is an answer. In a business purchase, the role is narrow and specific. It is rarely part of routine diligence, but it can be the right call when something in the records will not reconcile and the explanations offered do not hold together.

What the work looks like

A forensic accountant traces cash through bank records, compares sales to deposits, tests whether customers and invoices exist, and looks for patterns such as unusual timing or round-number entries. The work is documented carefully so findings can be explained to others, including a lender, a mediator or a court if it comes to that.

When it may be worth considering

Typical triggers are a gap between reported sales and bank deposits, records that change when you ask for them, expenses that no one can explain, or an owner who resists reasonable requests. One odd item is often an honest mistake. A pattern is a stronger reason to look closer, and the accountant can help you tell which you have.

How it differs from other accountants

A regular accountant or quality of earnings provider tests earnings broadly and reports what holds up. A forensic accountant digs into a specific question and builds evidence. Many purchases never need one, and a good diligence team will tell you when the issue is beyond their usual scope.

Before and after closing

Some buyers bring in a forensic accountant before closing, when findings can change the transaction. Others do so after, to support a claim under the agreement. Your lawyer can tell you what notice and time limits apply, so raise concerns early rather than waiting. Keep the investigation confidential.
