What you give up either way
- Official Verifactu/AEAT certification, legal warranty and audit support provided by vendor
- Polish of vendor SDKs, CLI, and Claude Code plugin that auto-writes integrations
- Enterprise support, SLA, and negotiated multi-NIF pricing and onboarding assistance
- Tight Stripe one‑click managed integration and production-hardened edge cases already handled
An open-source project doing the core job proves a replacement is possible. It does not prove it matches BeeL., and it does not prove anyone has run it for a month. How we decide.
