Best CRM for small businesses
Last verified:
Crail tracks 6 CRM vendors that list small businesses as a fit. These are the 5 that rank highest once the list is weighted for small businesses, and each one is shown with the published entry price, what that tier actually includes, and whether you can try it first — the facts that decide the shortlist at this size, rather than the same summary on every page.
How this list is weighted for small businesses
- 60% of the vendor's Crail agent-readiness score
- 15 points for a published free tier
- 15 points for being buyable self-serve, without a sales call
- up to 10 points for a low entry price (free tier, then a cheapest paid tier under $30, then under $75)
Startups and small businesses share the price-and-self-serve weighting; midmarket and enterprise share the compliance weighting. The full rules are on the methodology page.

FAQ
How is this CRM ranking calculated for small businesses?
This is not the raw agent-readiness leaderboard. Crail scores the 6 CRM vendors it tracks that fit small businesses, using 60% of the vendor's Crail agent-readiness score; 15 points for a published free tier; 15 points for being buyable self-serve, without a sales call; up to 10 points for a low entry price (free tier, then a cheapest paid tier under $30, then under $75). Attio ranks first on both measures: it holds the highest raw agent-readiness score on this list (91/100) and the top score once the small businesses weighting is applied.
What does the cheapest paid plan on this list cost?
Published monthly entry prices on this list run from $20/month (HubSpot CRM (Sales Hub), Starter tier) to $25/month (Salesforce Sales Cloud, Starter Suite tier). Attio ($35/year), Zoho CRM ($14/year) and Close ($9/year) are priced on a different basis, so they do not compare directly.
Can a small business trial these before committing?
Zoho CRM (15-day trial), Close (14-day trial) and Salesforce Sales Cloud (30-day trial). Attio, HubSpot CRM (Sales Hub), Zoho CRM and Salesforce Sales Cloud offer an ongoing free tier instead, which is the usual way in to this list.
