Key takeaways

Our verdict

Our verdict: Fusion Invoice is a niche but valuable tool for the self-hosted market. It offers a practical blend of invoicing and basic CRM, ideal for cost-conscious and privacy-focused individuals. However, the need for self-hosting adds technical overhead compared to SaaS alternatives, which may limit its appeal for non-technical users.
