Before you start: we recommend reviewing and correctly configuring your store’s tax settings in Shopify before completing the Comply onboarding process. Check the VAT configuration in Shopify guide to make sure everything is set up correctly.
To configure Comply for the Immediate Supply of Information (SII) regulation, please follow these steps:
Step 0. Configure the Fiscal Environment
To ensure proper configuration, you will need to select the following:
1. Scope of application
In this section, you must indicate the territory and tax conditions under which your company operates.
Select the following options:
Territory: Spain
Status: Not covered for any of the reasons specified in Articles 1.3, 3.3, and 5 of the Regulation
System: Subject to SII
2. Tax regime
Next, select the tax regime applicable to your company, according to Law 37/1992 on VAT.
This determines how VAT is calculated and reported for your transactions.
The most common option is the general regime, although there are special regimes (for example, for travel agencies or agricultural sectors).
3. Type of tax
Finally, indicate the type of tax that applies to your business activity:
VAT for mainland Spain and the Balearic Islands
IGIC in the Canary Islands
IPSI in Ceuta and Melilla
Step 1. SII Configuration
Complete the form with your company’s tax information.
Make sure to enter the details exactly as they appear in the official records of the Spanish Tax Agency (Agencia Tributaria).
Required information:
Company name (Legal name)
Tax Identification Number (NIF)
Full address: Street, number, building, floor, etc.
Postal code
City
Step 2. Activate Immediate Supply of Information (SII) on POS
Activate the Comply Spain module
The Comply Spain module records your transactions in line with Immediate Supply of Information (SII)
How to set it up:
Click Start setup
Select and activate the Comply Spain module
Save your changes
Step 3. Comply with the Invoicing Regulation
Add Comply to your smart grid
With the Comply tile, your staff can issue full invoices and see tax alerts to stay compliant with the Invoicing Regulation
How to set it up:
Go to page 1 of your smart grid
Tap Add tile
Select Comply Spain (Embedded apps → Comply → Comply Spain)
Save your changes
⚠️ Important: Before proceeding, make sure your store’s tax settings are correctly configured.
Incorrect or incomplete tax setup may prevent Comply from properly reporting your sales to the tax authorities.
Step 4. Place a test order
To verify that the configuration is correct and that you have activated the app as indicated in step 2, you need to place a test order from the POS.
On the screen you will see a circular icon indicating that Comply is waiting for an order.
Create a test order in Shopify POS for an amount greater than €0.00 (for example, €1.00). If the waiting time runs out, tap the Refresh button to reactivate Comply.
Comply will automatically verify that the sale has been fiscalised correctly.
If everything is correct, you will see a confirmation screen.
If there is an error, we will provide guidance on how to resolve it.
With these four simple steps, Comply will be fully configured and ready to operate under the SII (Immediate Supply of Information) regime.
