The Best CRM for Buying a Small Business
I built Searcher OS, so weigh this accordingly. Here's the short answer: if you're 1 buyer purchasing 1 business, use a CRM that already knows the acquisition stages (Interested, NDA, CIM, LOI, diligence). Searcher OS does that and also files broker emails to the right deal, reads the CIM and runs the SBA math, from free to $79/month. If 2 partners need 1 shared pipeline, HubSpot's free CRM or Airtable is the better fit today. Affinity, DealCloud and 4Degrees are built for investment firms.
I tracked my own search in a spreadsheet for a while. It held up until I had 30 conversations going and couldn't tell you which broker had sent which CIM.
What an acquisition CRM needs that a sales CRM lacks
A sales CRM tracks you selling to many customers. Buying a business runs the other way: you're the customer, a broker controls access, and most deals die between the NDA and the LOI. So the CRM has to hold different things.
- Acquisition stages. Interested, NDA signed, CIM review, conversations, LOI sent, due diligence, then closed or dead (with a reason, so you learn why deals die).
- Brokers as relationships. One broker sends you 6 deals over a year. Their contact record should show every deal and every email across all of them.
- Email on the deal. The broker's reply, the signed NDA and the CIM attachment belong on the deal card, without you copy-pasting them there.
- The CIM itself. A 40-page PDF you need to find again at LOI time, ideally with the numbers already pulled out.
- Financing math. Asking price, cash flow and a DSCR on the deal page, so a deal that can't carry an SBA loan gets killed early. (The free DSCR calculator works without an account.)

The options, one by one
1. Searcher OS
Free plan (3 active deals) · The Searcher $79/mo · The Deal Team $149/mo
I built it, so discount accordingly. The pipeline ships with the acquisition stages already in place (Interested, NDA Signed, CIM Review, Conversations, LOI Sent, Due Diligence, Closed or Dead) and flags a deal that sits too long in one. Broker email reaches the right deal by forwarding or by Gmail filters, a signed NDA checks off the NDA task, and a CIM attachment kicks off the AI analysis. Each deal page holds the broker and deal-team contacts, the timeline, tasks, the CIM and a DSCR from the financials. The catch: each account is 1 buyer’s pipeline, and you can import deals from CSV or XLSX but there is no pipeline export yet.
Pick it if: You are 1 buyer running a full search and want the CRM, the listings and the deal math in one place.
2. HubSpot
Free CRM (up to 2 users, 1,000 contacts) · Sales Hub Starter from $7 to $20 per seat/mo · Professional $90 to $100 per seat/mo plus $1,500 onboarding
A real sales CRM with a generous free tier. Deal pipelines, activity logging and email tracking are on the free plan, and 2 users fit inside it. You build the acquisition stages yourself, and nothing in it knows what a CIM, an add-back or an SBA loan is. It also has no listings, so every deal gets typed or imported in by hand.
Pick it if: You have 2 partners who need to share 1 pipeline and you are happy to configure stages yourself.
3. Airtable
Free plan · Team $20/user/mo · Business $45/user/mo (billed annually)
The tinkerer’s pick. A base with Deals, Brokers and Documents tables linked together gets you surprisingly far, and the Kanban view looks the part. Every field, formula and automation is yours to build and maintain, including the DSCR math. Email matching to deals means wiring up an integration yourself.
Pick it if: You like building your own system and want a shared, flexible database.
4. Notion or a spreadsheet
Google Sheets free · Notion free, paid plans from $10 per member/mo
Where almost everyone starts (I did). It costs nothing and it works for the first 10 or 15 deals. It breaks once broker replies live in Gmail, CIMs live in Downloads and the sheet is 2 weeks stale, because nothing connects them.
Pick it if: You are early, reviewing a handful of deals a month.
5. Affinity, DealCloud or 4Degrees
Affinity from $2,000 per user/yr · DealCloud and 4Degrees pricing not published
These are relationship CRMs for investment firms. Affinity lists private equity, venture capital, investment banking and family offices as its market. DealCloud (owned by Intapp) sells to private capital, advisory, legal and accounting firms. 4Degrees lists venture capital, private equity and M&A advisory. They are serious tools, priced and sold to firms. For an individual buyer purchasing 1 company, they are more CRM than the job needs.
Pick it if: You are an investment firm with a deal team, a fund and relationship data to manage.
6. DealNav
Basic $59/mo · Pro $99/mo
It shows up when people search for acquisition deal software, so here is the honest note: DealNav is a map-based CRM for real estate acquisitions, with county parcel records built in. Good at that. It is the wrong tool for buying an operating business.
Pick it if: You buy real estate.
How the Searcher OS pipeline works
Deals land on a Kanban board (or a sortable list) from the deal feed, from a manual entry for a deal a broker sent you directly, or from a CSV or XLSX import. Each stage has a clock: a deal sitting in Interested for 3 days gets flagged, and diligence gets 21. The pipeline guide has the full list.
Open a deal and you get the CRM view: financials with a calculated DSCR, the listing broker and anyone else on the deal team, tasks, a timeline of every email, call and meeting, and the CIM with its analysis.
Broker email gets there 1 of 3 ways: forward it to your Searcher OS address, auto-forward a dedicated search inbox, or connect Gmail so Searcher OS sets up forwarding filters (it never reads your inbox). The email setup guide walks through each. And if you want more on running the funnel itself, I wrote up how to build an acquisition pipeline and how to work with business brokers.
Where Searcher OS is the wrong pick
You have a partner. Each account is 1 buyer's pipeline. Two searchers who want to see and move the same deals should use HubSpot or Airtable for the shared pipeline.
You need your data out in a file. You can import deals, but exporting the pipeline or contacts isn't built yet. The PDF activity report is the only export today.
You're a fund. If you're managing LPs, portfolio companies and firm-wide relationship data, Affinity or DealCloud is built for that job.
Common questions
What CRM should I use to buy a small business?
If you are 1 buyer running a search, use a CRM built around acquisition stages. Searcher OS ships with the stages from Interested through NDA, CIM review, LOI and due diligence, files broker emails to the right deal, analyzes CIMs and does the SBA and DSCR math, with a free plan and a $79/month paid plan. If 2 partners need to share 1 pipeline, HubSpot’s free CRM (up to 2 users) or Airtable fits better. Affinity, DealCloud and 4Degrees are built for investment firms.
Can I use HubSpot to track business acquisitions?
Yes. The free HubSpot CRM covers up to 2 users and 1,000 contacts and includes deal pipelines and email tracking. You configure the acquisition stages yourself, and it has no listings feed, CIM analysis or SBA math, so those live in other tools.
What does an acquisition CRM need that a sales CRM lacks?
Stages that match how a deal moves (Interested, NDA signed, CIM review, conversations, LOI, due diligence, closed or dead), brokers as first-class contacts tied to many deals, broker emails filed to the right deal, the CIM stored on the deal, and financing math like DSCR next to the asking price.
What CRM do search fund teams use?
A funded search with 2 partners needs a shared pipeline, which HubSpot, Airtable and Notion all handle. Searcher OS is 1 buyer per account today, so partners would each run their own. Affinity, DealCloud and 4Degrees are sold to investment firms (private equity, venture capital, advisory) and are usually more than a 2-person search needs.
Is a spreadsheet good enough to track deals?
For the first 10 or 15 deals, yes. It breaks once broker replies, CIMs and the sheet live in 3 different places and the sheet falls behind. That is usually the point to move to a real CRM.
How much does Searcher OS cost?
The Free plan is $0 with no credit card and includes a pipeline with 3 active deals, 1 buy box, 1 AI CIM analysis a month and the deal feed on a 3-week delay. The Searcher is $79/month ($759/year) and The Deal Team is $149/month ($1,430/year). Paid plans start with a 7-day free trial.
