Lower-middle-market data room
The data room built only for lower-middle-market M&A
ClosingVault runs one kind of deal: the sale of a lower-middle-market business, up to $50 million, from teaser to close. We do one thing and we do it better than anyone else. A room with standard defaults is set up in about 3 minutes, and it’s fully customizable for any lower-middle-market deal.

Fundraising data room? Not us. Board portal? Not us. Lower-middle-market M&A? The best choice, bar none.
Who is ClosingVault for?
The people on a lower-middle-market sale: the broker or advisor running it, the buyer, the owners selling, and the advisors each of them brings.
-
Business brokers and M&A advisors
Run several sell-side deals from one account. Your seller adds documents in batches; each is filed against your checklist, and you run the buyers. For intermediaries.
-
Buyers, including search funders and small PE
Open a room for the target, send the seller your request list and watch it fill. For search funders, independent sponsors, family offices, small PE and strategic acquirers. For buyers.
-
Owner-sellers
Be diligence-ready before the LOI is signed. Add documents as you find them and see what’s still missing. For sellers.
-
Their advisors
QoE providers, attorneys and lenders each get exactly the access they’re given, on a tamper-evident log. Invited into a room?
Who is ClosingVault not for?
Anyone whose deal isn’t the sale of a company. We’d rather say so up front:
- Raising a round? You want a fundraising data room — not us.
- Running board meetings? You want a board portal — not us.
- Selling or buying a lower-middle-market business? That’s all we build for.
What does building for one kind of deal buy you?
Features that exist because these deals need them.
| Feature | What it does |
|---|---|
| Filing to the due diligence checklist | Files each document under the checklist item it answers and ticks the item |
| Items that don’t apply | Each stays open until a document arrives or the seller signs an N/A |
| NDA in the room | The buyer reads the NDA in full and signs it in the room, which opens the CIM |
| Owner-majority LOI | An LOI is accepted, countered or declined only when owners holding more than half of the company approve |
| Exclusivity | Accepting an LOI starts countdown clocks and pauses the other buyers’ access |
| Buyer access expiry | Always ends: 2 weeks by default, 2 months at most |
| Automatic redaction | Removes Social Security, card and bank account numbers from the file |
| Bank statements | Each filed under its own account |
| Weekly update | A one-page status email for each party, every Monday |
| Ask the Data Room | Finds the documents that answer a plain-words question |
How long does it take to set up a room?
About 3 minutes with standard defaults. Then change any of it: upload your own Excel request list, release checklist phases on your own dates, choose who can download, and set when each buyer’s access ends. It’s fully customizable for any lower-middle-market deal up to $50 million. Already mid-deal somewhere else? Move a deal in progress in about 5 minutes. Organizing files before you open one? Start from the free data room index template.
Is ClosingVault really the most feature-rich data room for these deals?
Yes. ClosingVault is the most feature-rich VDR for lower-middle-market deals on the market, with more features than $10,000 products. The evidence is step by step: ClosingVault and seven low-cost data rooms on the 20 steps of a sale, one fact per cell, each checked on the vendor’s own site.
What does it cost?
Plans start at $79 a month, billed yearly. The firm that opens the room pays. Invited buyers, sellers, owners and their teams are always free and unlimited. Every plan and price.
Lower-middle-market data room questions
I’m a business broker with four live listings — is ClosingVault built for deals my
size?
Yes. ClosingVault is built only for lower-middle-market M&A, deals up to $50 million, and a broker runs several sell-side deals from one account: Plus runs 3 active deal rooms at once and Professional runs 10.
We’re a startup raising a seed round — should we use ClosingVault for investor
diligence?
No. ClosingVault is built for selling and buying companies; for a round you want a fundraising data room.
Our company holds quarterly board meetings — can we use ClosingVault as a board
portal?
No. ClosingVault isn’t a board portal; it is built only for lower-middle-market M&A.
I’m a search funder buying my first company — can I run the data room myself?
Yes. Open a room for the target and send the seller your due diligence request list; every document the seller adds is filed against it.
I own an HVAC company with two partners — who gets to accept a buyer’s LOI in
ClosingVault?
The owners, by majority. An LOI is accepted, countered or declined only when owners holding more than half of the company approve.
I’m a broker with three buyers reading the CIM — what happens to the other two
when my seller accepts an LOI?
Their access is paused, not ended. Accepting an LOI with an exclusivity period pauses the other buyers’ access, and it comes back on its own if exclusivity ends.
I’m an M&A advisor with a seller ready to start Monday — how long does it take
to set up a room?
About 3 minutes with standard defaults. After that every part is customizable, from the checklist to who can download.
I’m the buyer’s QoE provider and I’ve been invited into the room — do I have to
pay?
No. The firm that opens the room pays. Invited buyers, sellers, owners and their teams are always free and unlimited.
