StowbillVirtual data room providers compared
There are dozens of data room providers and most lists rank them by who paid to be on the list. This page groups eight of them by the kind of deal they suit. Stowbill is one of the eight, so read our own entry with that in mind.
The providers
Features are from each vendor's own website in November 2026. We have not tested the other products.

How to choose
- Size of deal and buyer expectations. On a large cross-border sale, buyers' lawyers may expect a certified, well-known provider.
- How many rooms a year. One deal suits per-project pricing; several a year suits a subscription or per-user plan.
- Whether you need the process as well as the room. Most rooms stop at documents and Q&A.
- File types. If the financial model is in Excel, check that it can be viewed without being downloaded.
- Where the data is hosted, if your client or regulator cares.
Questions to ask before you sign
- Is the price per page, per gigabyte, per user or per project, and what happens if the deal runs three months over?
- Are Q&A, redaction, watermarking and reports included or charged as extras?
- Are outside users free?
- Which security certifications do you hold, and can we see the report?
- Can we export the full activity log and the index when the deal ends?
- How long is data kept after the room closes, and what does archiving cost?
Where Stowbill fits, and where it does not
Stowbill suits a firm that runs several mid-sized mandates a year and wants one system for the mandate, the buyers and the room. It does not suit a very large auction, or a deal where the buyer's side requires a certified provider.
Stowbill does not have AI features, page-by-page viewing analytics, a mobile app, or SOC 2 or ISO 27001 certification today. Single sign-on is built but not yet switched on.
Questions
Which is the best virtual data room provider?
There is no single best. Datasite and Intralinks lead on the largest deals, iDeals and Firmex in the mid-market, and lower-cost tools serve startups. The right one depends on the deal.
How much does a data room cost?
From under $100 a month for simple tools to tens of thousands of dollars for a large project. See our pricing guide for the models.
Do I need a data room at all?
For anything shared with outside parties under an NDA, yes: a shared drive cannot show who opened what or keep bidders apart.
