Standout Differences
The most AI-native of the three
Attio's Ask Attio natural-language search, configurable AI Agents, and Call Intelligence build automation and AI research directly into the CRM rather than layering it on as an add-on.
Attio
Marketing, sales, and support in one affordable suite
EngageBay bundles email marketing automation, sales pipelines, live chat, and helpdesk ticketing under a single free plan for up to 250 contacts, positioning it as a lower-cost HubSpot alternative.
EngageBay
The only one with native quote-to-cash
Odoo CRM can convert a closed opportunity straight into a quote, sales order, stock reservation, and invoice without leaving the record, a workflow that requires separate tools for Attio or EngageBay.
Odoo CRM
Free plans differ sharply in structure
Attio's free plan caps out at 3 seats, EngageBay's caps out at 250 contacts, and Odoo CRM's One App Free plan allows unlimited users on the CRM app alone, reflecting three different growth ceilings before a business needs to pay.
