Data Room Cost
Competitor pricing details are based on publicly available information as of mid-2026. The model matters more than the sticker: it decides whether thorough diligence costs you extra.
| Model | How it bills | What it does to your invoice |
|---|---|---|
| Per-page billing | You pay for every page uploaded, at a rate set in your contract rather than published | ✗ The total is unknowable until the deal closes, because the rate is contractual, not published |
| Per-user billing | You pay for every named user or seat | ✗ Costs climb as diligence widens; teams ration who gets access |
| Storage tiers | You pay by gigabytes stored, quoted after a sales call | ~ Price is unpredictable until the call, and grows with the room |
| Flat plans (Sifrsys) | One published monthly price per tier | ✓ Upload everything. The invoice is the same number every month |

A mid-market M&A process can run to tens of thousands of pages, and under per-page billing nobody can tell you the total until it is over. We checked ten providers on 4 August 2026 and none publishes a per-page rate. Intralinks names pages as a billable unit in its published billing terms and leaves the rate to a per-customer Work Order, which is the pattern across the category: the unit is disclosed, the number is not. Six months on Sifrsys Pro costs $5,994, and you could work that out before uploading the first document. Per-page pricing also taxes thoroughness, because the more complete your data room, the more you owe. We think that incentive points the wrong way, so our plans are flat.
Included in Every Plan
The capabilities a deal actually depends on are in every plan, including the free one.
Ask questions in plain language. Every answer cites the exact page in the PDF or the exact cell range in the spreadsheet, so you verify instead of trusting.
The AI only retrieves from documents each participant is allowed to see, enforced at the database level with Row-Level Security, not by app-layer filtering.
Viewed documents carry dynamic watermarks, so every page a participant sees is traceable to them.
Route diligence questions to the right owner, answer once, and keep the whole thread inside the room instead of email.
Every document access is recorded in a hash-chained audit trail, on every plan including the free one. Owners and admins can export it, which is the record buyers and counsel ask for.
The price on this page is the price. No per-page fees, no surprise line items, and a 14-day full-platform trial with no credit card.
Price-Lock Guarantee
Deals run long. Your data room bill should not drift while they do.
Sifrsys commits to no surprise mid-contract increases and 90 days notice for any pricing change. Reviewers of some legacy providers, based on publicly available information, report notable increases arriving at renewal. We put the opposite in writing. Sifrsys is also independent: not a subsidiary of Datasite, unlike Firmex and Ansarada, based on publicly available information. And rather than asking you to take security on faith, the Trust Center lists exactly what we do and do not claim, verified against what is actually shipped.
The Founding 10
A young vendor asking to hold your deal documents owes you more than a discount. The first ten paying companies on Sifrsys get three commitments, in writing.
The price you sign at is your price for as long as you stay subscribed. Not for a year. Not until renewal. For the life of the subscription.
We move your documents, folder structure, and permission setup out of your current data room ourselves, at no charge. You review the result instead of doing the work.
You get the founder's direct line, not a ticket queue. Answers the same business day, and a real say in what gets built next.
Why offer this? Because we have more to prove than you do. An established vendor sells you a track record. We are offering the terms a vendor with a track record never needs to. Ten companies. When the spots are gone, this section comes down.
