How to Choose a Virtual Data Room for M&A
Security rarely decides which data room to use. These are the criteria that do — and the questions to put to a provider before choosing one.

Data room for M&A
Documents and access control, the request list, Q&A, findings and the due diligence report. From sell-side preparation through to signing, with several bidder groups working in parallel.

The process
Sell-side prep
Build the room before anyone is invited. Uploads index themselves against the list.
Buy-side invited
Invite the other side when the room is ready. Each bidder group sees what you open to it.
Buy-side diligence
Several bidder groups work in parallel, each blind to the others.
Findings noted
The buy-side records deviations against documents, privately.
DD report → signing
The report generates from the findings. The log is exportable in full.
The request list
A new room opens on a request list written for M&A, so it can be live in minutes with nobody drafting it first. Or bring your own: it imports as an Excel file, with the room built around it — categories, numbering and wording as you wrote them. Upload yourself or send it to us and we set the room up for you.

Features for M&A
01
Invite multiple bidder groups into the same room without them seeing each other, and phase access by round — everyone in phase one, the shortlist in phase two. All of them working at the same time, and you control who on the sell-side may upload.
02
Hand requests to a reviewer or to a work package the team shares, and see who has what.
03
Upload a file, write an answer, or mark a request not applicable.
04
Restrict per file or per group, watermark on view, control export rights, and export the complete activity log.

Ask a connected assistant “which contracts have a change-of-control clause?”. It answers from the documents in this room, with every source named, and it can see which requests are still open.

Three. The facility agreement requires mandatory prepayment on a change of control; the largest customer contract needs the customer’s consent, not to be unreasonably withheld; the head-office lease needs the landlord’s. The other customer contracts under request 2.2 have none.
