Scell.io vs Xero
Xero leader AU/UK vs Scell.io specialised in French Factur-X
Xero is the cloud accounting leader in Australia and the UK, with a mature REST API, OAuth 2.0, and official SDKs for .NET, Java, Node.js, PHP, Python, Ruby. Very good UBL and Peppol BIS Billing 3.0 coverage for UK/AU B2G. However, support for Factur-X (hybrid PDF+XML CII) and French-specific EN 16931 rules (BR-CO-26, French BT-IDs) is missing. Scell.io doesn't compete on full accounting coverage, but offers a France 2026-compliant layer packageable into an existing stack, with multi-tenancy suited to French IT services companies.
