Data room or Google Drive and Dropbox? Where shared folders break down in a deal

Google Drive and Dropbox are very good products. Your team probably lives in one of them already, and for most work they are exactly right.

That is the problem. They are so convenient that founders and finance teams reach for them by default when a deal starts, and the gaps only become visible at the worst possible moment: when a bidder walks away, or a buyer’s lawyer asks for a record of what was shared, or an employee file ends up somewhere it should not.

This guide is not here to talk you out of a shared drive. For some deals it is the right call. It is here to show you exactly where the line falls.

When is a shared drive genuinely enough?

If every statement below is true for your deal, a well-configured shared folder will probably do.

  • There is one counterparty, not a competitive process.
  • You already have a working relationship with them.
  • Fewer than about 100 documents will be shared.
  • Nothing in the set contains personal data about employees or customers.
  • A leak would be embarrassing rather than damaging.
  • Neither side will need a formal record of disclosure later.

Good examples: sending an early-stage angel your deck, financial model and incorporation documents; sharing a lease pack with a single prospective tenant; exchanging drafts with your own lawyer.

Miss two or more and you should at least price a proper room.

Where do shared folders break in a real deal?

There are five moments where drive-based sharing tends to fail. Each one is minor on its own. Together they explain why advisers rarely run a sale on a shared drive.

1. The second bidder arrives. Shared drives think in terms of folders shared with people. Running parallel bidders means duplicating folders, managing near-identical copies and hoping nobody shares the wrong link. A deal room handles this with permission groups.

2. A bidder drops out. You remove their access to the folder. Anything they already downloaded stays on their laptop, readable forever. Rooms with document rights management can stop downloaded files opening once access is revoked.

3. Questions start. Diligence generates hundreds of questions. On a shared drive they arrive by email, sit in a spreadsheet and get answered inconsistently. A data room routes, approves and logs them in one place.

4. Someone takes a screenshot. A dynamic watermark naming the viewer on every page is standard in deal rooms and uncommon or limited in general file-sharing plans. Without one, a leaked image cannot be traced.

5. The lawyers ask what was disclosed. Warranty protection in a sale often depends on what was fairly disclosed. A deal room gives you a time-stamped log and an archive of the room as it stood at signing. Reconstructing the same from drive version history and email is slow and incomplete.

A shared drive tells you what is in a folder today. A data room tells you who saw what, and when, for the whole life of the deal.

How do the three options compare, feature by feature?

The comparison below is for typical business plans of the two drives against a dedicated deal room. Exact features differ by plan and change over time, so treat the middle columns as a guide and check the plan you have.

A drive covers sign-in and familiarity. The deal controls, from revoke-after-download to Q&A with approvals, come built in only with a data room.

What does each option really cost?

The sticker price favours the drive you already pay for. The full cost often does not. Here are three scenarios, with software figures indicative only; confirm current prices with each provider.

ScenarioShared drive: softwareShared drive: extra adviser and admin timeData room: softwareData room: extra time
Angel round, 3 investors, 2 monthsAlready paidMinimalAbout 300 USD at 149 USD a monthMinimal
Owner-led sale, 6 bidders, 5 monthsAlready paid20 to 40 hours managing copies, emails and Q&AAbout 750 to 1,500 USD on a flat plan5 to 10 hours
Mid-market auction, 40 bidder users, 5 monthsExtra seats if bidders need accounts60 hours or more, plus disclosure reconstructionTypically 3,000 to 15,000 USD15 to 25 hours

At adviser rates of a few hundred US dollars an hour, the middle row tips the balance quickly. In our data, deal-focused rooms with a published price include Ellty at 149 USD a month and CapLinked at 299 USD a month, and both list a built-in Q&A. Onehub, at 15 USD a month, is closer to a branded file-sharing portal and does not list Q&A. Our pricing page covers the full field.

Are there privacy rules that push you toward a data room?

Not directly; no law says “use a data room”. But privacy rules shape what you must be able to show.

If the documents include personal data about people in the EU or UK, the business sharing them must be able to demonstrate that sharing was limited and secure. The GDPR’s accountability principle in Article 5(2) puts the burden of proof on you, and the UK ICO’s data sharing code expects records of what was shared, with whom and why. A permission set and an audit trail give you those records. A drive folder shared by link does not.

US targets in healthcare have a sharper version of the same problem. Protected health information is governed by HIPAA, and the tool holding it needs the right contract and controls. In practice most sellers keep patient-level data out of diligence entirely.

If you stay on a shared drive, how do you lock it down?

If your deal fits the first row, a few settings close the biggest gaps:

  • Share with named email addresses only. Turn off “anyone with the link”.
  • Create a separate top-level folder for the deal, owned by a company account, not a personal one.
  • Disable downloading, printing and copying for viewers where your plan allows it.
  • Set an expiry date on every external share.
  • Keep a simple log: date, document, recipient. It is tedious, and it is better than nothing.
  • When the deal ends, remove all external access and export a dated copy of the folder.

Drive and Dropbox are not the only middle ground. Three other options come up often.

SharePoint or OneDrive. If your company runs on Microsoft 365, a dedicated SharePoint site for the deal is a step up from ad hoc folders: you can use groups, restrict external sharing and apply sensitivity labels. It still lacks a deal Q&A workflow and a clean disclosure archive, and setting it up well usually needs your IT team.

Box. Box sits between a drive and a deal room. In our data it lists watermarking, an audit trail, single sign-on, two-factor sign-in and a HIPAA certification, with a published entry price of 15 USD per user per month. It does not list a deal Q&A module or document rights management, and per-user pricing gets expensive when bidders need seats.

Link-tracking tools such as DocSend. These are built for sending a deck and seeing who opened which page. In our data DocSend lists watermarking, an audit trail and eSignature at 45 USD per user per month. That is useful for the outreach stage of a raise; it is not a substitute for a structured diligence room.

What if you start on a drive and outgrow it?

It happens often: a single interested buyer turns into three, or a friendly raise attracts a lead fund with a formal request list. Moving is straightforward if your folders are already tidy. Export, rebuild the structure using a numbered scheme such as our data room index template, upload, set groups and invite. For a few hundred files that is a day’s work, and our five-day setup guide covers the rest.

Most providers in our rankings offer a free trial, so you can test the move before committing. Ellty’s runs 14 days.

Frequently asked questions

Is Google Drive secure enough for due diligence?

Drive is secure as a platform, but it lacks deal controls such as per-bidder permission groups, dynamic watermarks, Q&A and a disclosure archive. For a single trusted counterparty it can work; for a competitive process it is a weak fit.

Can Dropbox be used as a data room?

For small, simple deals, yes, if you restrict sharing to named users and set expiry dates. Some Dropbox plans add watermarking and view tracking, but structured Q&A and per-bidder groups usually require a dedicated room.

Is a data room much more expensive than a shared drive?

Entry-level deal rooms in our data start around 149 to 299 USD a month. For a sale with several bidders, the adviser time saved usually outweighs the software cost.

Do buyers expect a data room?

In a structured sale, institutional buyers and their advisers generally do. A shared drive can make a process look less organised, which affects bidder confidence.

Can I move from Google Drive to a data room mid-deal?

Yes. Export the folder, rebuild it with a numbered index, upload and set permission groups. For a few hundred files it is roughly a day of work.
