Which should you choose?

Wave: Free-to-start invoicing and accounting for small businesses, with paid payments and payroll add-ons.

Odoo: Open-source modular ERP covering inventory, accounting, CRM, POS, website and more.

The best way to decide is to run the same week of real work through both — most offer a free plan or trial — and compare how long tasks take, what your team prefers, and the total cost for your number of users including renewal pricing.
