our call
Start with MyFoglio — highest vibe code, weakest moat.
MyFoglio

- Invoice, quote, and credit note creation UI.
- Automatic PDF invoice generation from structured data.
- FatturaPA/FatturaElettronica XML file generation from order data.
- Expense entry and receipt attachment logging.
what you lose
- Direct legal liability coverage for non-compliant tax digital archiving.
- Native accountant portal access and automated multi-format exports for tax advisors.
- Turnkey SDI web service routing without paying third-party API gateway fees.
real moats
- AgID-compliant digital preservation (conservazione sostitutiva) infrastructure and legal liability coverage.

open source escape hatches
- Open Tax Solver / tax rules engines Mixed
- GOBL Apache-2.0
- Invopop Peppol / fatturapa MIT
