| | | | - | - | | Developer | [Invopop](https://invopop.com) | | Category | Government | | Scope | B2B | | Country | [Italy](/compliance/italy) | The [SDI](https://www.agenziaentrate.gov.it) (*Sistema di Interscambio*) is Italy's central hub for transmitting, validating, and delivering all electronic invoices throughout the country. It is managed by the Italian tax authority (*Agenzia delle Entrate*). Electronic invoicing is mandatory for all businesses in Italy. The SDI system operates using a standardized XML format called FatturaPA, which ensures all invoices contain the required information and comply with the strict validation rules established by the Italian tax authority. Invopop simplifies SDI integration by allowing you to work with GOBL format instead of XML, providing synchronous validation before submission, and offering a simple API integration with automatic handling of SDI notifications and status updates. Invopop has partnered with [A-Cube](https://www.acubeapi.com) to provide SDI integration services. **Key features** * **Workflow automation:** This app provides automated workflows for sending and receiving invoices through the SDI system. * **FatturaPA XML generation:** Automatically converts GOBL documents into compliant FatturaPA XML format. * **Real-time status updates:** Automatically handles SDI notifications and status updates, including delivery confirmations and acceptance/rejection notifications. * **Bidirectional support:** Send invoices to SDI and receive invoices from suppliers through the same app. * **Customer registration:** Register companies to receive invoices through SDI with a simple workflow step. * **GOBL FatturaPA integration:** Uses the open-source [GOBL FatturaPA](https://github.com/invopop/gobl.fatturapa) library for conversions. Make sure to check out our [SDI Italy Sending Guide](/guides/it-sdi-sending) and [SDI Italy Receiving Guide](/guides/it-sdi-receiving) for instructions on how to issue and receive invoices. ## FAQ Invoicing questions Install the [Italy app](/apps/italy) for structured invoicing through SDI, or the Smart Receipts app for B2C-only AdE CF receipts. Run invoices through a workflow with the **Send invoice to SDI** step — see the [issuing guide](/guides/it-sdi-invoicing). Retail receipts (*documento commerciale*, commonly called *scontrino*) are not SDI invoices — they are reported to the tax authority as *corrispettivi* through a separate channel. Use the [Smart Receipts Italy app](/apps/smart-receipts-italy) for those, and see the [Smart Receipts issuing guide](/guides/it-ticket). See the [Italy tax regime in GOBL](https://docs.gobl.org/regimes/it) for tax categories, codice fiscale rules, and SDI-specific extensions. The [`it-sdi-v1`](https://docs.gobl.org/addons/it-sdi-v1) addon documents required FatturaPA fields. The **Send invoice to SDI** step completes as soon as SDI accepts the file — it doesn't wait for SDI's verdict. What takes time is SDI's own processing: a rejection usually arrives within minutes, but delivery confirmations can take up to 5 days. Each verdict is recorded against the invoice as a status entry, so nothing is stuck while you wait. See the [status guide](/guides/it-sdi-status) for the full lifecycle. SDI confirms delivery with an `RC` (*ricevuta di consegna*) notification, recorded on the invoice as a status entry with the GOBL status `acknowledged`. A rejection arrives as `NS` with status `error`. Every notification and what it means is covered in the [status guide](/guides/it-sdi-status). Set a reserved *codice destinatario* on the customer — for example `SIMNS00` to simulate a rejection. The sandbox simulates SDI end to end and feeds back the notifications a real exchange would produce; any ordinary code resolves to a successful delivery. The full list of reserved codes is in the [issuing guide](/guides/it-sdi-invoicing#testing-in-the-sandbox). Both Italian tax identifiers have their own place on a party. The *partita IVA* (VAT number) goes in `tax_id`, and the *codice fiscale* goes in `identities` under the key `it-fiscal-code`. A party may carry both. An Italian supplier always needs a *partita IVA*. An Italian customer needs at least one of the two — which one depends on who they are, covered in the [issuing guide](/guides/it-sdi-invoicing#identifying-the-customer). Here's an example showing both identifiers on a supplier: ```json Supplier with Partita IVA and Codice Fiscale theme={"system"} { "supplier": { "name": "MªF. Services", "tax_id": { "country": "IT", "code": "12345678903" }, "identities": [ { "key": "it-fiscal-code", "code": "MRTMTT91D08F205J" } ] } } ``` Send it through SDI as usual — an Italian supplier reports the invoice there whoever the customer is. SDI has no way to deliver outside Italy, though, so it won't reach the customer that way: send them their copy yourself, normally as a PDF. It's the same invoice travelling by two routes, and only the FatturaPA file is the legal one. An Italian customer needs either a *partita IVA* or a *codice fiscale*. A customer outside Italy needs neither — their country is enough, so leave the code out rather than inventing a placeholder. See [identifying the customer](/guides/it-sdi-invoicing#identifying-the-customer). Add an item attribute to the invoice line with `type` `N.DOC.COMM` and the receipt's identifier in `text`, its progressive number in `amount` and its date in `date`. The `it-sdi-v1` addon writes each item attribute as an `AltriDatiGestionali` block (`TipoDato`, `RiferimentoTesto`, `RiferimentoNumero`, `RiferimentoData`). The `type` is limited to 10 ASCII characters. See the "Invoice after a documento commerciale" example in the [issuing guide](/guides/it-sdi-invoicing#example-invoices). Registering supplier questions Provide the supplier's Partita IVA and Codice Fiscale (where different) in their party configuration. No certificate upload is needed — Invopop transmits to SDI over its own accredited channel. No supplier certificates are required. Invopop exchanges documents with SDI over its own accredited channel; only the Partita IVA and routing metadata are stored. You don't need to. SDI has no supplier registration for sending: set the supplier's Partita IVA on the party and send. Registration is only needed for *receiving* — see the [receiving invoices guide](/guides/it-sdi-reception). None — Invopop exchanges documents with SDI over its own accredited channel, so suppliers don't manage any certificates. Invoices to public administrations (`FPA12`) also need a qualified electronic signature, which Invopop applies with its own seal when it sends them. Receiving questions Register Invopop's recipient code (`BDCS3JD`) with the tax authority and run the registration workflow on the company's party entry. Invopop automatically receives matching invoices and routes them through the configured import workflow. See the [receiving invoices guide](/guides/it-sdi-reception). Inbound FatturaPA XMLs are parsed via [`gobl.fatturapa`](https://github.com/invopop/gobl.fatturapa). The original signed XML is preserved as a silo entry attachment alongside the GOBL representation. Register the company for reception in your sandbox workspace, then send a sandbox invoice addressed to it — the app loops it back to you as an inbound delivery and runs your import workflow, exactly as a real delivery would. This is the only way to receive an invoice in sandbox: there is no tax authority to register with, and no real supplier can reach it. See [receiving your own invoices](/guides/it-sdi-invoicing#receiving-your-own-invoices). The import step attempts to convert the FatturaPA document into [GOBL](https://docs.gobl.org). If conversion fails, the step returns `KO`, but the original file stays stored — the invoice can be re-processed later without SDI needing to redeliver it. If the invoice has significant structural issues that prevent conversion, you may need to contact the sender to request a corrected invoice. Invoices are typically received within minutes after being sent by suppliers through SDI. The automatic import process in Invopop processes them as soon as they are received by our system. Yes, multiple companies can be registered to receive invoices through a single Invopop workspace. For each company, you must: 1. Register the recipient code `BDCS3JD` with the Italian tax authority for that specific company 2. Have its tax ID registered by running the registration workflow on the company's party entry 3. Use the same import workflow configured in the app settings This two-step registration process (with the tax authority and with Invopop) must be completed for each company you want to register. This is particularly useful for white-labeling scenarios where a user manages multiple entities. Yes, but only one party at a time can hold a given tax ID. Run the [unregister workflow](/guides/it-sdi-reception#unregistering-a-company) on the party that currently holds it, then register the new one. Registering a tax ID that another party already holds fails with a clear error. Sandbox and live are counted separately, so the same tax ID can be registered in both at the same time. The two-step registration process serves different purposes: 1. **Registering with the Italian tax authority** - Tells SDI to route invoices addressed to your company to Invopop's channel using the *Codice Destinatario* `BDCS3JD`. 2. **Registering with Invopop** (the registration workflow) - Tells Invopop which invoices to accept and process for your workspace. Both steps are necessary: the first routes the invoices to Invopop, and the second ensures Invopop knows which workspace should receive those invoices. Signed FatturaPA XML (versions 1.2.x), conforming to the Agenzia delle Entrate schema. The original file is kept attached to the entry exactly as SDI delivered it, alongside SDI's delivery metadata. More answers in our [Italy FAQ](/faq/italy) section The following workflow actions will be available once you install and enable this app:
3
Issue GOBL invoices in the Italian SDI using the FatturaPA format. Register a GOBL party (customer) to receive invoices from the Italian SDI. Stop a registered party from receiving invoices from the Italian SDI, freeing its tax ID to be registered again.

The invoice is an ordinary SDI invoice that references the receipt issued for the same sale. Notice: * the line item carries an `attributes` entry with `type` `N.DOC.COMM`, the receipt's AdE document number in `text`, its progressive number in `amount`, and the receipt date in `date`, * the `it-sdi-v1` addon converts each item attribute into an `AltriDatiGestionali` block: `type` becomes `TipoDato`, `text` becomes `RiferimentoTesto`, `amount` becomes `RiferimentoNumero`, and `date` becomes `RiferimentoData`, which is the layout the AdE describes for invoices preceded by a receipt, * `type` is limited to 10 ASCII characters and `text` to 60 characters, and `amount` is rendered with at least two decimals, so `7816` arrives at SDI as `7816.00`, * the receipt's document number is the `ade-ref` stamp the Smart Receipts app adds to the receipt's header after the AdE accepts it, * `issue_date` is the day of the sale, because FatturaPA's `Data` comes from `issue_date` (`op_date` is not written to the XML), and without further tags `gobl build` sets the document type to `TD01`, * the Smart Receipt itself is not changed by this invoice, and your own VAT records must remove the invoiced amount from that day's *corrispettivi*.
