For most lower middle market deals, a data room with a mid-range price is enough. Ansarada lists plans from $99 a month, ShareFile's data room plan lists $69.30 per user a month, and DocSend's data room plan lists $180 a month. Firmex, DealRoom, Datasite, and Intralinks give prices only by quote, and the last two suit auctions that bankers run with many bidders.

We checked each vendor's pricing page on November 12, 2026.
Ansarada's prices are month to month, and they fall to $69 a month if you commit for 12 months. ShareFile includes 1 GB of storage with each user license. DocSend's price comes from its pricing page.
How much does a data room cost for a small deal?
If you choose a room that publishes its price, expect to pay a few hundred dollars a month. A ShareFile room for five users costs about $347 a month when you pay yearly. Ansarada's 1 GB Essentials plan costs $1,229 for a single month, or $519 a month if you commit for 12 months.
Ansarada sets its price by how much data you store, so check the size of your files before you choose a plan. Its pricing page also says you pay nothing until you invite someone from outside your firm. That lets you set up the whole room before any buyer sees it.
When is Datasite or Intralinks worth the cost?
They make sense for a full auction, with 50 or more buyers, two rounds of bids, and a long list of buyer questions to answer. On a deal that size, the room costs little next to the success fee. On smaller deals, we rarely suggest them.
Neither company publishes a price. Datasite says its pricing is "customized for every transaction," and Intralinks bases each quote on how much data you store, how many users you add, and how long the deal runs. Get both quotes before you sign the engagement letter, so you can include the cost when you discuss your fee with the seller.
Datasite also owns Ansarada. Ansarada says the purchase closed in September 2024, and it still runs under its own name.
When is a mid-priced room enough?
A mid-priced room does the job for most deals under about $50 million of enterprise value, with 10 to 40 buyers. ShareFile's data room plan lists permissions, watermarks, and a record of who opened each file. DealRoom lists a tool for buyer questions and permissions, and its price includes every seat.
Firmex sells a room for a single deal or a yearly subscription for as many deals as you like. If you run several deals a year, get both quotes and compare them.
Can you use Google Drive or Box instead?
Yes, for a very small deal with a few buyers you already trust. You set each permission by hand, and you see less about who read which file. Before anyone gets a link, read how to share a deal confidentially.
DocSend sits between a shared drive and a full data room. It shows what each visitor looked at and tells you when a buyer opens a file. That helps you see which buyers are serious before you call them.
Which room should you choose?
If the deal is worth under $2 million and you have five buyers or fewer, use DocSend or view-only links in the Drive or Box account you already have. Get the NDA signed before you share anything.
Between $2 million and $50 million, with 10 to 40 buyers, use a room with a published price such as Ansarada or ShareFile, or ask Firmex for a single-deal quote. At $50 million and up, in an auction with two rounds of bids, get quotes from Datasite and Intralinks. Compare how each one handles buyer questions and keeps groups of bidders apart, and do not judge them on price alone. If you sell several companies a year, compare a Firmex or DealRoom subscription with the quotes you would get for each deal.
These size ranges follow the IBBA and M&A Source Market Pulse, which calls deals under $2 million Main Street and deals from $2 million to $50 million the lower middle market. To see what is for sale in that range, read what the lower middle market is. A data room only helps if the right buyers sign the NDA, and our guide to a buyer list that gets responses covers that step.
Where PrivSource fits
PrivSource is not a data room. It finds the buyers who will use one. AI Buyer List shows the buyers who match your deal and the reason each one would buy, before you share any details. It is free for advisors.
