Scell.io vs FreshBooks
FreshBooks SMB-friendly vs Scell.io developer API
FreshBooks is a cloud invoicing platform very popular in North America, focused on user experience for freelancers and small teams. The API is documented but product-centred (templates, time tracking, expenses). No native Factur-X support. For French publishers or IT services companies wanting a pure e-invoicing API, compliant with the 2026 reform, with PHP/JS SDKs and multi-tenant architecture, Scell.io is more suitable. FreshBooks remains relevant for freelancers looking for a finished product.
