Diligence is where deals slow down, get repriced, and die, and almost none of that is because the business was bad. It is because answers took weeks, documents could not be found, and a buyer's confidence eroded one late reply at a time. The list a buyer sends is remarkably consistent, which means the whole thing can be assembled in advance.
What the due diligence list covers
Corporate records and ownership, three years of financial statements and tax filings, management accounts, the customer and supplier contracts that matter, the lease or property title, employee list with terms, any litigation or disputes, insurance policies, licenses and permits, intellectual property and its ownership, loans and security given, and the asset register. Due diligence documentation of that kind exists somewhere in every business; the work is finding it, not creating it, and finding it takes far longer than anyone expects.
A data room due diligence checklist, organized the way it will be read
A data room due diligence checklist is only useful if the room is organized to match it: numbered top-level folders following the standard categories, and files named so their contents are obvious without opening them. Buyers and their advisers work through a list, and a room organized the way the seller thinks about the business rather than the way diligence asks about it generates dozens of clarifying questions that all cost days. Match the structure to the request, not to your own filing habits.
Run the M&A checklist on yourself first
The m&a checklist exercise has a second purpose beyond assembly, which is that you find what a buyer would find, while you still control the timing. A missing signature, a lease that expired and rolled over, a contract that assigns nothing, an employee whose terms were never documented: all are fixable in advance and all are leverage in a buyer's hands if discovered during diligence. Sellers who run the list on themselves first are negotiating from a different position from those who do not.
Questions people ask about due diligence list
What due diligence documentation does the list ask for?
Corporate records, three years of accounts and tax filings, key contracts, property, employees, litigation, insurance, licenses, intellectual property, borrowings and the asset register.
How should a data room be organised?
To match the request list: numbered top-level folders following the standard categories, with filenames that make contents obvious. Organizing it your own way generates clarifying questions.
Why run the diligence list on yourself first?
Because you find what the buyer would find while you still control the timing. The same issue is fixable beforehand and is leverage in a buyer's hands if it surfaces mid-diligence.
