Odoo CRM

Odoo draws its free line somewhere nobody else does. Rather than capping users or records, it gives you one application at no cost for an unlimited number of people. If the application you pick is the CRM, a company of forty can run its pipeline on Odoo Online without paying anything, which is a genuinely different offer from the two-user free tiers elsewhere in this field.

Above that, pricing is per user for all applications together: EUR 19.90 a month on yearly billing for Standard, or EUR 29.90 for Custom, which adds on-premise deployment, the Studio builder, multi-company support and an external API. The core is open source, so self-hosting is a real route and the data can sit on machines you control.

On value that is hard to argue with: an unlimited-user CRM at no cost. The catch is that the free tier is a doorway rather than a destination. The moment a second app is useful — invoicing, helpdesk, projects, all of which sit right there — the price becomes per user for everything, and the step is deliberate. There is also the configuration burden that comes with any suite: this is more product than a small sales team needs, and making it fit takes work that a single-purpose CRM does not ask for.
