As published, Italy's Sistema di Interscambio (SDI) is operated by the Agenzia delle Entrate, the Italian Revenue Agency. Business-to-business e-invoicing has been mandatory since 1 January 2019, making Italy the first EU country to require it for all VAT-registered businesses, with the remaining exemptions for micro-businesses removed from January 2024. Invoices are exchanged as FatturaPA, a structured XML format, and EU Council Decision 2024/3150, published 19 December 2024, permits Italy to keep requiring e-invoicing through SDI until 31 December 2027 (as published — confirm current requirements with your adviser).
LATYNEX Digital builds the workflow around the invoice data your SDI channel or e-invoicing provider needs. This page covers it for Milan businesses. The general service is at Workflow Automation & Systems Integration, and the market overview is at LATYNEX Digital for businesses in Milan. Delivery is in English, and this page names no client.
Typical industries
- Small and mid-sized retailers and service businesses
- Wholesalers and distributors invoicing domestic B2B customers
- Manufacturers and design-sector suppliers billing Italian clients
- Finance and back-office teams preparing invoice data
- Businesses replacing a manual FatturaPA workflow with a structured one
Common lead-handling problems
- Sales recorded in a spreadsheet or ERP export, then re-keyed into FatturaPA fields
- Invoice data split across several tools with no single source
- No record of which invoices the SDI rejected, or why
- A missing or malformed field found only when the SDI returns a rejection notice
- No internal owner for exception invoices awaiting correction and resubmission
Direct answer
If your Milan business issues invoices that must pass through the SDI, LATYNEX can build a workflow that turns your existing sales or billing records into one clean invoice data set, checks it against the FatturaPA fields your certified SDI channel or e-invoicing provider expects, and gives every rejected or exception invoice an owner before it is resubmitted.
Why the global page and the Milan hub are not enough
The global Workflow Automation & Systems Integration page has no national e-invoicing exchange to design against, and the Milan hub is broad discovery for the market. Here the design point is that SDI has run as a mandatory, no-exemption clearance channel since 2019 under a standing EU derogation, so the invoice data has to be right in FatturaPA structure the first time, not patched after a rejection notice.
What we configure and build
The work sits before your certified SDI channel or e-invoicing provider, not in place of it.
- An invoice data workflow pulling from your existing sales, billing or ERP records
- Field checks against the FatturaPA structure your integrator or e-invoicing provider confirms
- A queue for SDI-rejected or exception invoices, with an owner and a status
- A history of what was prepared, submitted, and the SDI outcome
- A written handover once the workflow is running
What stays with you and your SDI channel or accountant
Transmitting the FatturaPA invoice through the SDI, and any dealings with the Agenzia delle Entrate, stay with your accountant, e-invoicing provider or certified channel. Whether a given invoice meets current SDI requirements is for you and your adviser; we prepare and check the underlying data, we do not transmit it through SDI.
What needs API support or custom scope
LATYNEX claims no SDI channel, no Agenzia delle Entrate accreditation, and no invoice-transmission capability. Any connection to your certified provider, ERP or accounting system is scoped per project through the documented API or export format if access is permitted, after technical review.
What we do not do, and where LATYNEX is not the right fit
LATYNEX does not give tax or legal advice, does not transmit invoices through the SDI, does not say an invoice is compliant, and holds no Italian tax-authority accreditation. It has no Milan office or named clients, and delivery is in English only. If you already run an ERP with a working SDI connector, this page is not for you.
How delivery actually works
LATYNEX Digital has no office in Milan and does not claim one. We work with Milan businesses remotely, over video calls and written updates, in English, with the same team and process as in every other market.

No. Transmission through the SDI stays with your accountant, e-invoicing provider or certified channel. We prepare and check the invoice data beforehand.
Since when has e-invoicing been mandatory in Italy?+
As published, B2B e-invoicing through the SDI has been mandatory since 1 January 2019, with the remaining exemptions for micro-businesses removed from January 2024.
How long can Italy keep requiring e-invoicing through SDI?+
As published, EU Council Decision 2024/3150, published 19 December 2024, permits Italy to continue requiring e-invoicing through the SDI until 31 December 2027. Confirm the current position with your adviser.
Does this make our invoicing compliant?+
No. We give no tax or legal advice and cannot say your invoicing meets requirements. Confirm current requirements with your adviser; we build to the data set they and your SDI channel specify.

In EUR, by Latynex Trade OÜ, a company registered in Estonia (EU). Tax treatment for a client in Italy is confirmed on the quote, and we do not give tax advice.
