Odoo is an open-source suite of business management (ERP) applications that brings every part of a company onto one platform: CRM & sales, accounting/invoicing, inventory & manufacturing, HR & payroll, marketing (email/SMS/social), project management, website & e-commerce, and point of sale. Odoo builds AI directly into its modules (CRM automation, invoice OCR, an agentic AI assistant on the Custom plan) and has an ecosystem of 40,000+ community apps. Pricing is transparent and per-user, with no hidden fees, serving everyone from micro businesses (1-5 employees) to large enterprises (250+ employees).

Where it falls short
