Overview
Wave and Odoo Community Edition both offer free accounting software, making them attractive options for startups and small businesses on tight budgets. Wave is a free, ad-supported accounting platform focused on invoicing, expense tracking, and basic bookkeeping. Odoo Community Edition provides free accounting as part of a full open-source ERP. Both are genuinely free, but with different trade-offs.

The Hosting Trade-off
Wave's biggest advantage is zero setup — sign up and start. It is cloud-hosted with no technical requirements. Odoo Community Edition requires hosting on a server, which means either technical knowledge or a hosting provider like DeployMonkey. This is the fundamental trade-off: Wave is easier to start; Odoo provides more capabilities.
Revenue Model
Wave makes money through payment processing fees (2.9% + $0.60 per credit card transaction) and optional paid add-ons (payroll, receipt scanning). Odoo Community is truly free open-source software — there are no ads, no payment processing fees from Odoo, and no paywalled features within the CE scope.
When to Choose Wave
- You are a solo entrepreneur or very small team
- You need free accounting with zero setup
- Basic invoicing and expense tracking is sufficient
- You are in the US or Canada and want simple payroll
- Technical server management is not an option
When to Choose Odoo CE
- You need more than accounting (CRM, inventory, project, etc.)
- You want multi-currency accounting
- You plan to grow and may need Enterprise features later
- You want open-source control over your data
- You have hosting capability (or use DeployMonkey)
Growth Path
Wave's growth path is limited — when you outgrow it, you migrate to QuickBooks or another platform. Odoo CE has a clear upgrade path: add Enterprise features (payroll, advanced accounting, studio) when ready, without changing platforms or re-entering data.
DeployMonkey Advantage
DeployMonkey eliminates Odoo CE's hosting barrier. We deploy and manage your Odoo instance, giving you Wave-like simplicity with Odoo's full ERP capabilities — still at a fraction of the cost of traditional ERP hosting.
