How to Find a Complete Due Diligence Checklist for your Deal

Every deal is different, therefore no two due diligence checklists will be identical. The above list is just a general guideline of some materials collected during due diligence. For your own process, check with your team if you have conducting similar deals in the past to begin your checklist.

For example one deal may need the following categories - administrative, financial, asset, human resources, environmental, intellectual property, taxes, and legal.

How to Collect Due Diligence Documents

What emerges from bringing together all of the documents outlined above is a true understanding of your business and what’s ‘under the hood.’

Many of the documents will be partially or fully available straight away (for example, details of your employees and their training to date) while others, such as the audited financial statements, will by their very nature, take longer to put together.

If your company has high quality CRM, ERP or BI systems, they can be used to bring together all kinds of useful data used in due diligence. The feedback provided by these systems also gives reassurance to potential buyers that there’s no human error in the data they’ve received.

Furthermore, as we never tire of mentioning, information on your firm is as useful to you as it is to a buyer of a firm, and should be analyzed on an ongoing basis in any case.

Collecting the due diligence documents should be done in a systematic manner that allows you to see where documents can be obtained, whether more should be added, progress reports on their collection and more. We suggest putting together a list in a table format structured similarly to the one provided below:

Keeping structured records like this in a spreadsheet also allows you to filter for results faster when buyers ask for documents. Whatever headings you opt for, the ‘last updated’ column is particularly important, allowing you to see at a glance when due diligence documents were last updated and thus, how likely they are to be relevant.

When Should You Provide Due Diligence Documents to the Buyer?

Keeping thorough and updated due diligence documents allows you to get relevant information over to the buyer of your business efficiently and with as little friction as possible. But the question then arises:

• When should due diligence documents be provided to the buyer?
• Can this be done too quickly?

Absolutely. Unfortunately, the world of M&A is full of tire kickers who enjoy finding out about businesses simply to see what’s out there. Asking you for due diligence documents rarely costs them anything (hence the reason why some bankers push for charging buyers for due diligence).

The best policy is to begin by providing audited financial statements - a great signaling device for any owner looking to sell their business that their ship is in order - and send over documents as they’re requested by the buyer, who should have signed an NDA in advance.

The more buyers you speak to, the more likely it is that you’ll be able to anticipate what documents they’re looking for in advance, making the process even more efficient.
