Ask a deal team what they want from a data room budget and the answer is rarely “the cheapest”. It is closer to “no surprises, and nothing we have to work around”. A room that costs $15 a month but sends bidder questions to email, cannot stop a download or needs a second tool for redaction is not cheap once the workarounds are counted.
That is the idea behind our best-value list. This article explains how the list weighs price against capability, why the cheapest rooms on our roster do not lead it, and how vendors that publish no price at all are scored.
How does the best-value list define value?
The list uses our six criteria with weights that put cost first without letting it decide alone.
| Criterion | Best-value weight | Overall weight | What it asks |
|---|---|---|---|
| Cost predictability | 40% | 15% | Is the price published, stable and clear about what each tier includes? |
| Diligence toolkit | 22% | 26% | Does the room run a real deal: Q&A, permissions, reporting? |
| Data protection | 18% | 21% | Attestations and document-level controls |
| Ease of adoption | 12% | 17% | Setup speed and guest learning curve |
| Checklist breadth | 5% | 12% | Native features out of twelve |
| Deal support | 3% | 9% | Published support and onboarding |
Two bonuses follow: 3 points for a published entry price and 1 point for a free trial. Both reward what a value buyer can verify before talking to sales.
Note what Cost predictability measures. It is not the lowest price; it is how well a buyer can budget. A published flat monthly price with clear limits scores well. A per-user price scores lower, because the bill grows with every adviser. A quoted project price with page or storage overages scores lower again, because the final bill is hard to predict.
Where do the cheapest rooms land?
Eight of the 18 providers we track publish an entry price. Here is where each one lands on the best-value list.
Best-value list score for every provider with a published price
The order makes the formula visible. Onehub and Box are the cheapest entry points on our roster, and both gain the full published-price and trial bonuses. Neither lists a structured Q&A module, and Onehub lists no document rights control, so their toolkit and protection marks hold them back. Ellty leads by combining the top Cost predictability mark we give, from a published $149 flat monthly price and a 14-day free trial, with a Diligence toolkit mark level with iDeals and Datasite. Its stated gaps, no native redaction, SSO or public API, matter less on a value list but are worth checking against your requirements; the Ellty profile lists them.
How are quote-only vendors scored?
Ten of the 18 providers publish no price. A value list has to handle them honestly: it cannot invent a price, and it should not punish a vendor simply for selling through quotes.
Our approach has three parts. Quote-only vendors receive no published-price bonus. Their Cost predictability mark reflects what is known about their pricing model, such as whether quotes are typically flat for a term or add overages, and is generally lower than a published flat price. And everything else is scored normally, so a strong toolkit can still carry a quote-only room high.
That is why iDeals ranks second on the best-value list without the price bonus, and Datasite third. Their toolkit and protection marks are among the highest we give, and a value buyer who needs a full auction room may well find a fair quote from either.
What does a worked example show?
Take a modest sell-side process: six months, three paid users on the seller’s side, entry-level plans. The table uses published entry prices from our facts; real plans may have user, storage or feature limits that change the total.
| Provider | Published entry price | Six months, three paid users | Structured Q&A listed |
|---|---|---|---|
| Onehub | $15 a month | $90 | No |
| Box | $15 per user/mo | $270 | No |
| Citrix ShareFile | $55 a month | $330 | No |
| Digify | $120 a month | $720 | No |
| DocSend | $45 per user/mo | $810 | No |
| Ellty | $149 a month | $894 | Yes |
| SecureDocs | $250 a month | $1,500 | Yes |
| CapLinked | $299 a month | $1,794 | Yes |
Two things stand out. The five cheapest options in this scenario all lack a Q&A module, so a competitive process would run its questions outside the room. And among rooms that do list Q&A, the spread is about $900 over six months, a small sum next to adviser fees on almost any transaction. Add a second bidder group, more advisers on per-user plans or a three-month delay, and the gaps change again, which is why predictability carries more weight than the headline price.

What hidden costs change the value picture?
Entry prices describe the start of a bill, not the end of it. Before comparing value, ask every vendor about the lines that tend to appear later.
| Cost line | Where it usually appears | Question to ask |
|---|---|---|
| Extra months after the committed term | Quoted projects | What is the monthly rate once the term ends? |
| Storage or page overage | Quoted projects, some entry plans | What is the cap, and the rate above it? |
| Additional paid users | Per-user plans | Do advisers and reviewers count as paid users? |
| Archive at close | Most models | Is a full archive with audit log included, or billed? |
| Setup, indexing or a project manager | Quoted, service-led vendors | Is onboarding included or priced separately? |
| AI features | Varies by vendor | Are AI features in the plan you are buying, or an add-on? |
A room with a slightly higher entry price and none of these lines can cost less over a real deal than a cheaper room with several. That is the practical meaning of Cost predictability, and the reason it is scored separately from price.
How should you shop for value?
Finding the best-value data room for your deal
- 1List what you cannot work around
Q&A for a multi-bidder sale, view-only rights, redaction or SSO. Anything on this list is not optional, whatever the price.
- 2Filter on those features
Remove every room that does not list them. Cheap rooms that fail here are not good value for your deal.
- 3Price one scenario everywhere
Same term, extra months, users and storage, for published and quoted vendors alike.
- 4Check the limits
Ask about user caps, storage caps, overage rates and the cost of an archive at close.
- 5Use a free trial on the finalist
Build your real index and invite one outside reviewer to confirm the room works before paying for the full term.
Frequently asked questions
What is the best-value virtual data room?
On our current best-value list, Ellty ranks first, followed by iDeals and Datasite. The list weights cost predictability at 40% and still gives the diligence toolkit and data protection 40% between them.
What is the cheapest data room?
Among the providers we track, Onehub and Box publish the lowest entry prices at $15 a month and $15 per user a month. Neither lists a structured Q&A module in our facts.
Can a quote-only data room be good value?
Yes. iDeals and Datasite rank second and third on our best-value list without the published-price bonus, because their toolkit and protection marks are high. Ask for a quote on a fixed scenario to compare.
Why is per-user pricing scored lower for predictability?
Because the bill grows with every adviser, colleague and reviewer added, and deal teams often grow as a process moves forward.
Are the prices on this page current?
They are indicative entry prices from our facts file, in USD. Vendors change plans often, so confirm current prices and limits on each vendor's site.
