Set up SamBooks' SDI recipient code (7HD37X0) in your AdE tax drawer: a step-by-step guide

What the SDI recipient code is

The recipient code (codice destinatario) is the 7-character digital identifier that electronic XML invoices use to reach the right software through the Italian Revenue Agency's Exchange System (SDI). It is the digital equivalent of the delivery address on an envelope: without a recipient code, your supplier invoices sit in your tax drawer (cassetto fiscale) and you have to download them by hand.

SamBooks' recipient code is 7HD37X0. Enter it once in your AdE tax drawer and, from that moment, every supplier invoice your vendors issue arrives straight into SamBooks, ready for AI-assisted automatic bookkeeping.

This applies only to companies and entities subject to e-invoicing. Flat-rate taxpayers (the RF19 regime) do not receive supplier invoices in SDI XML format: there is nothing to configure.

The 6 steps (~5 minutes)

1. Sign in to the Revenue Agency's IAMPE portal

Go to iampe.agenziaentrate.gov.it and sign in with SPID, CIE or Fisconline credentials as the company's legal representative or as a portal-authorised delegate.

If you sign in as a private citizen (not as the company) you will not see the "Fatturazione elettronica" (e-invoicing) menus — you must be acting under the company's identity.

2. Open the e-invoicing section

From the Servizi (Services) menu look for "Fatturazione elettronica", or use the direct link: portale.agenziaentrate.gov.it/PortaleWeb/servizi/accessoFatturazione.

3. Select the "Incaricato" role and enter the VAT number

On the subject-selection screen:

• Select "Incaricato" (Delegate), not "Cittadino" (Citizen)
• Enter your company VAT number (11 digits)
• Click "Accedi" or "Avanti"

Tip: while you are here, if you have not done so yet, also enrol in the Revenue Agency's e-invoice preservation service (conservazione). It is free and keeps you compliant with the ten-year digital archiving obligation.

4. Open "Registration of the electronic address"

Look for "Registrazione dell'indirizzo telematico dove ricevere tutte le fatture elettroniche" (Register the electronic address where you receive all e-invoices) — this is the setting that tells SDI where to deliver your documents.

5. Enter the recipient code 7HD37X0

Fill in the form:

• In the "Codice destinatario" (Recipient code) field enter exactly: 7HD37X0
• A PEC address is not required. You can leave the PEC field empty: SamBooks receives through the SDI code, not through certified email.
• Click "Aggiorna" or "Conferma" to save.

The setting takes effect immediately. From now on, suppliers invoicing your VAT number need to do nothing: their software issues the document, SDI reads the recipient code registered on your tax drawer and delivers it to SamBooks.

6. Leave the portal — you're done

Close the AdE session. The next supplier invoice you receive will land in SamBooks. You'll find it under Supplier invoices → Inbox, already parsed and ready for AI-assisted double-entry bookkeeping.

Check that it works

The first XML supplier invoices arrive within a few minutes of the supplier sending them. To test right away you can ask a supplier to issue you a €0 test credit note — or simply wait for the next regular invoice.

Under Settings → Company profile you can always see the recipient code currently configured. If you switch software and want to stop receiving here, just go back to AdE and replace 7HD37X0 with the new system's code.

E-invoice preservation is free

By law, e-invoices must be kept in compliant preservation for 10 years: a PDF copy on your computer is not enough. Compliant preservation (conservazione sostitutiva) seals every invoice with a digital signature, a timestamp and metadata, so it stays intact and legally valid for the tax authorities and in the event of an audit.

The key thing to know is that the Revenue Agency provides this service for free for every e-invoice that goes through SDI, both issued and received. You just enrol once in the preservation Service Agreement from the Fatture e Corrispettivi portal (the "Tip" in step 3): from then on AdE preserves your invoices in compliant form for 15 years, even if you switch software later.

That is exactly why SamBooks does not sell a preservation service: for e-invoices there is no point paying a third-party preservation provider when the very same service — public and free — is already offered by the Revenue Agency. We show you how to enable it in a few clicks; SamBooks' internal archive stays an operational backup and does not replace AdE's compliant preservation.

Frequently asked questions

What if I already configured a different recipient code or a PEC address? Simply replace the existing value with 7HD37X0. AdE allows a single digital delivery address at a time: changing it does not lose any historical data — it only affects new invoices.

How long before SDI uses the new code? The change is immediate. Invoices issued a few seconds after the update already arrive in SamBooks.

A supplier asks me for my recipient code — what do I tell them? Give them 7HD37X0 (or let them read it from SDI: their software usually resolves the code automatically from your VAT number).

I'm a flat-rate taxpayer (RF19) — do I still need to configure this? No. Flat-rate taxpayers do not receive supplier invoices in SDI XML format: the supplier issues them on paper or as a plain PDF. The "Configure tax drawer" step is automatically hidden in your SamBooks dashboard.
