Gennai is a well-designed invoice automation platform. InboxBill takes a different approach in several key areas — FreeAgent-native integration, privacy-first email capture, and UK-specific features. Here's an honest comparison.
| Feature | InboxBill | Gennai |
|---|---|---|
| FreeAgent integration | Native (built-first) | Not supported |
| Email capture method | Forwarding (no inbox access) | OAuth / portal upload |
| UK VAT handling | Full (20%, 5%, 0%, exempt) | Basic |
| Pricing | From £15/month | From $29/month USD |
| UK focus | UK-first | International |
| Payment terms handling | Yes, honours supplier terms | Basic |
| Auto-approval rules | Yes | Yes |
| Duplicate detection | Yes | Yes |
For UK small businesses using FreeAgent, InboxBill's native integration is a decisive advantage. Gennai doesn't integrate with FreeAgent at all — meaning if you use FreeAgent, you'd still need to manually enter bills after Gennai extracts the data, defeating the purpose.
InboxBill is built for UK businesses: UK date formats (DD/MM/YYYY), UK VAT rates and codes, GBP as the default currency, and FreeAgent as the primary integration. Gennai is an international platform that doesn't optimise for UK workflows.
