An owner-managed company selling up or bringing in investors faces the same diligence as a larger firm, with fewer people to run it. Ellty is our first pick because it delivers the complete deal toolkit at a listed price; SecureDocs, CapLinked, Onehub and Citrix ShareFile follow, each with published pricing.
A complete transaction data room with AI tools inside it and a list price on the website.
9.2/10Outstanding
Ellty gives an owner-managed company the same complete toolkit enterprise platforms provide: permission groups, Q&A, per-viewer watermarks, control over printing and downloads, and a full activity log, plus AI features and native e-signature. The $149/mo entry price is listed and the 14-day free trial is long enough to build the whole index.
What we liked
Every core diligence control on our checklist: routed Q&A, group permissions, viewer watermarks, print and download blocking, activity log
AI tools and signing are part of the product, not add-ons
Highest usability score in our ranking (9.8), with self-serve setup for admins
Watch out for
Neither SSO nor a public API at our last check
You redact outside the room, since there is no native tool
No native mobile app; reviewers use the mobile browser
One monthly fee, a room you can open without IT, with signing and Q&A built in.
7.7/10Good
SecureDocs lists pricing from $250/mo, is easy to use and includes e-signature, Q&A and an API. There is no redaction or SSO, so it suits smaller sales best.
What we liked
Flat published price of $250/mo, so a long deal does not inflate with every new user
One of the easier rooms to administer; scored 8.7 on everyday usability
Signing is native, so NDAs can be executed before access opens
Watch out for
Lacks ISO 27001 certification, SSO and a redaction tool
Low-cost secure file sharing and client portals with watermarks, an audit trail and a mobile app.
7.5/10Good
Onehub starts at $15/mo and suits ongoing sharing with clients or an accountant. It has no Q&A or document rights control, so it is not built for a competitive sale.
What we liked
Very low published entry price of $15/mo
Easy to use for outside parties; scored 8.8 on everyday usability
Native mobile app, public API and bulk upload
Watch out for
No Q&A module, redaction or e-signature
No document rights control to block printing or saving after access
No ISO 27001 or single sign-on, and no AI features
A secure client portal for exchanging and signing files, used widely by accountants, lawyers and advisers.
8.0/10Very good
Citrix ShareFile lists pricing from $55/mo, with e-signature, a mobile app and HIPAA among its certifications. It is a file-sharing platform without a Q&A module.
What we liked
Listed entry price of $55/mo and a trial you can start alone
SOC 2 report, ISO 27001 certificate and HIPAA support
Signing, a phone and tablet app, single sign-on and a public API
Watch out for
No managed log for buyer questions
Neither redaction nor AI tooling
Deal workflow and support sit below the specialist rooms
Prices in USD at the entry level; indicative, confirm with the provider.
Same questions, fewer people
When an owner-managed company is sold, the buyer’s accountants and lawyers bring the same request list they would bring to a much bigger business: three years of accounts, customer contracts, employee terms, leases, IP, tax filings. What changes is who answers. Often it is the owner, the finance manager and an external accountant, working evenings around the day job.
That is why we do not recommend a cut-down tool for small companies. The room still needs a Q&A module, permission groups and a full activity log. What it also needs is a published price and setup that one person can finish in a day.

Citrix ShareFile scores higher overall than SecureDocs, CapLinked and Onehub, but ranks last here because it lacks Q&A, which matters in a sale. The score itself comes from our six-criteria method.
Mistakes owners make
Waiting until a buyer asks is the big one. Pulling documents together under a buyer’s deadline is stressful and leads to gaps. Build the room as soon as you decide to sell, even if no buyer is in sight.
Another is answering questions by phone. It feels faster, but nothing is recorded, and later disputes over what was disclosed become word against word. Use the Q&A module or at least confirm answers in writing inside the room.
A third is giving the buyer download rights on everything. Customer lists and pricing are commercially sensitive. Keep them view-only until exclusivity is agreed.
Talk to your accountant first
Your accountant may already have a preferred structure for the financial folders. Agree it before you upload, so the buyer’s accountants find what they expect.
When a simpler tool is enough
Not every small company needs a deal room all year. If you only share monthly accounts with a bookkeeper or send contracts to a handful of clients, a file-sharing service with watermarking and two-factor login, such as Onehub or ShareFile, covers it at a lower monthly cost. The moment a buyer, investor or lender starts formal diligence, the needs change: questions must be logged, sensitive files restricted and every view recorded. At that point move the relevant documents into a full deal room rather than stretching a sharing tool past what it was designed to do. Ellty’s 14-day free trial makes it easy to test that move before you commit.
Budget notes
At Ellty’s listed $149/mo, a four-month sale costs about $600. SecureDocs ($250/mo) and CapLinked ($299/mo) are also flat monthly prices. Onehub ($15/mo) and Citrix ShareFile ($55/mo) are cheaper for ongoing sharing but lack sale-specific tools. Our pricing guide compares totals over different terms, and the startup fundraising shortlist covers raising investment.
Want a shortlist for your situation?
Five questions, three matches from our reviews, in about a minute.
If you are selling the company, raising investment or sharing sensitive files with outside advisers, yes. Buyers and investors expect organised documents, controlled access and a record of who saw what, regardless of company size.
What is the cheapest data room with Q&A?
Among providers that publish prices, Ellty lists $149/mo and CapLinked $299/mo, and both include a Q&A module. Onehub and Citrix ShareFile cost less to start but have no Q&A.
Can I use Dropbox or Google Drive instead?
For casual sharing, yes. For a sale or investment round they lack Q&A, viewer watermarks and detailed activity logs, which buyers' advisers expect.
How long will I need the data room?
A small business sale often takes three to six months from first buyer contact to completion. Plan for the longer end.
