Tyler
What the M&A data room does at each stage of the deal
Five stages, from preparation to the closing archive
01
Preparation
2 to 4 weeks
Who is in the room
Seller, adviser, counsel
What the room does
Build the index, bulk upload the diligence set, and redact personal data before anyone outside the deal holds a link.
02
Teaser and NDA
1 to 2 weeks
Who is in the room
Approached buyers
What the room does
One link per buyer, gated by NDA, showing the teaser only. Acceptance is logged with email, time and IP.
03
First round
3 to 6 weeks
Who is in the room
Five to fifteen bidders
What the room does
Bidder groups open different folders of the same room, and page-by-page analytics show who is really reading before indicative offers land.
04
Confirmatory diligence
4 to 8 weeks
Who is in the room
Two or three bidders and their advisers
What the room does
Deeper folders open, threaded Q&A routes questions to the right workstream, and every view and download lands in the audit log.
05
Signing and close
1 week
Who is in the room
Buyer, seller, counsel
What the room does
Freeze the room, export the audit log, and hand over an archive that matches the disclosure schedule.
The M&A data room index
The eight folders buyers expect to find
This is the structure a buy-side team opens first, and the one advisers rebuild on every deal. Papermark generates it for you, or you drag your own folders in and the room indexes them automatically.
- Top-level folders
- 8
- Documents in a typical mid-market room
- 190
For the full document list by category, see the data room checklist.

One room, four levels of access
Bidder groups, not one shared link
Everyone works from the same index, and each group sees a different room behind it. Permissions are set per folder and per group, so opening the employment folder for the final bidder does not open it for the other five.
- Full access
- View only
- No access
| Folder | Round 1 bidders | Round 2 bidders | Exclusivity | Advisers and counsel |
|---|---|---|---|---|
| Corporate and governance | ||||
| Financials | ||||
| Commercial and customers | ||||
| Legal and contracts | ||||
| People and employment | ||||
| Technology and IP | ||||
| Property and assets | ||||
| Compliance and insurance |
Employment files usually open only after exclusivity, and only once names and personal data are gone. That pass runs inside the room with AI redaction.
The controls a sell-side process leans on
In the order they come up during the deal
NDA before the first page
Every viewer accepts your NDA before a document loads, and the acceptance is logged with email, time and IP for the closing file.
See how it works →Dynamic watermarking
Each page carries the viewer's email, IP and timestamp as it renders, so a leaked screenshot traces back to one bidder.
See how it works →Bidder groups
Folder and file permissions per group, so round one, round two and exclusivity see different rooms behind one index.
See how it works →AI redaction
Sweep every page for names, addresses and account numbers, approve each hit, and share a version with the text removed rather than covered.
See how it works →Threaded Q&A
Buyer questions arrive in the room, route to the right workstream, and export to the closing binder instead of sitting in an inbox.
See how it works →Page-by-page analytics and audit log
See which bidder read the working capital schedule and for how long, with an append-only log of every view and download.

M&A data room pricing compared
What the same 4,000-page diligence set costs to host
Papermark Data Rooms
€99
per month, flat
Unlimited documents, unlimited data rooms and unlimited data room visitors. The page count never changes the invoice.
Per-page VDR pricing
$1,600 to $3,400
for the same set
Enterprise rooms such as Datasite bill roughly $0.40 to $0.85 per page, so a late upload of board packs adds cost mid-process.
Per-deal enterprise quote
$7,500+
per deal, typical entry point
Intralinks and comparable platforms quote per transaction, with scoping and onboarding before the room opens.
The full plan ladder, including the tiers that carry AI redaction, is on the Data Rooms pricing page.
