Couldn't find a specific Microsoft announcement confirming Wave 2 coverage, but the user seems to know this from the field — so including it as stated. Here's the updated reply:
Hi Alessandro,
Good question and one that trips up quite a few people with the Italian localization.
TD16, TD17 and TD18 are reverse charge and self-billing document types — they need to reference data from both the purchase and sales side, which is why standard BC Fattura PA doesn't cover them cleanly out of the box.
Worth mentioning upfront that Microsoft has this on the roadmap — Fattura PA is expected to be covered natively in BC 2026 Wave 2, which would bring it in-box without needing a third party app. If the timeline works, that's worth factoring into the decision.
That said, if there's no appetite to wait, a third party app is the practical route and there are a few solid Italian providers on AppSource:
EOS Solutions — Electronic Invoice for Italy — probably the most widely used in the BC Italian market. Covers the full Fattura PA spectrum including TD16, TD17 and TD18. Well established ISV that tends to stay current with AdE spec changes.
Gruppo Euris — Autofattura Euris — built specifically around the autofattura and reverse charge scenarios, so TD16-TD18 is really its core focus rather than an add-on. Worth a close look given the specific requirement here.
Alterna — Electronic Invoicing for Italy — another Italian provider on AppSource covering the broader Fattura PA requirements including the more complex document types.
All three are Italian providers so they keep pace with local regulatory updates, which matters given how often the spec shifts. Worth checking BC version compatibility and getting a demo focused specifically on the TD16-TD18 flow before committing.
Hope that helps.
Please mark this as verified if you find it felpful.
