Mollie is an authorised European provider operating fully in Italy. For this reason, your terminals will not appear automatically in the Italian tax registry for electronic payment tools, and you will need to enter the details manually. Don’t worry: it’s a simple, quick process and fully compliant with the regulations.
Here’s how to do it:
Step 1: Gather your Mollie details
Before accessing the portal, make sure you have the following information ready:
Italian or foreign acquirer: Foreign
Acquirer tax code: 815839091B01
Acquirer name: Mollie BV
Merchant agreement contract number: your Mollie organisation ID. You can find it in the top-right corner of your monthly invoice, or in your dashboard by clicking the profile icon in the top-left corner (it’s the number starting with #)
Terminal ID: specific to each device. To find it, log in to your Mollie Dashboard → Point of sale → click on the terminal → Terminal information
Use the following depending on your terminal type:
PAX terminals and TAP: use the Serial number
Tap to Pay (Mollie app or Tap app): use the Terminal ID
Step 2: Access the Invoices and Receipts portal
Go to ivaservizi.agenziaentrate.gov.it/portale/ and log in using SPID, CIE, CNS, or Entratel/Fisconline credentials. You can complete the procedure yourself or ask your accountant to do it on your behalf.
Step 3: Add the terminal and link it to the electronic cash register
In the side menu, select Device linking – POS → Manage connections
Click Add POS, then Add acquirer
Enter all the information collected in Step 1
Select your cash register and click Connect
Done. Your Mollie terminal is now linked to your cash register.
👉 For more detailed instructions, we recommend consulting the full Help Centre article and the official operational guide on linking POS terminals to cash registers published by the Italian Revenue Agency.
