With the implementation of the Verifactu regulation and new point-of-sale tax compliance requirements, Shopify POS and Comply now provide a proactive alert system to ensure legal compliance for every transaction. These warnings appear immediately before order completion and are designed to prevent errors that could lead to regulatory penalties.
Below is a detailed overview of each tax compliance alert detected by Comply, including the triggering conditions and how to resolve them correctly.
Tax compliance alert types
1. Update Your Shopify POS Version
Alert message:
The current app version is not compatible. Please update to ensure proper functionality of Comply.
Why this appears
Comply requires Shopify POS version 10.7 or higher to operate with the latest tax compliance features, such as automated invoice generation, embedded Verifactu and TicketBAI QR codes, and real-time tax data validation.
How to resolve
Update your Shopify POS app via the App Store (iOS) or Google Play (Android). Ensure that the installed version is 10.7 or later to guarantee full compliance support.
2. Add Customer Tax Information
Alert message:
Order amount exceeds €3,000. Add customer tax information to issue a full invoice.
Why this appears
According to Spanish tax regulations, a full invoice including the buyer’s tax data is mandatory when an order exceeds €3,000. This requirement is part of the Agencia Tributaria’s regulatory framework for anti-fraud controls and traceability.
How to resolve
Tap the alert message to enter the required tax fields: full name, NIF/CIF (Spanish tax ID), and fiscal address. This will enable Comply to generate a valid full invoice in compliance with Spanish tax authorities.
3. Complete Missing Tax Details for the Selected Customer
Alert message:
You added a customer without tax information. Add details if a full invoice is required.
Why this appears
This alert is triggered when a customer is added to the order but no tax information has been provided. Even if the order total is below €3,000, the customer may request a full invoice, in which case these details are mandatory.
How to resolve
Tap the alert to enter the customer's full name, NIF/CIF, and fiscal address. This allows Comply to issue a compliant full invoice when requested.
4. Cash Payment Limit for Spanish Residents
Alert message:
Order exceeds €1,000. Cash payment not permitted if the customer is a Spanish resident.
Why this appears
In accordance with Law 11/2021, cash payments of €1,000 or more are prohibited when the purchaser is an individual or professional fiscally domiciled in Spain. This law aims to reduce the use of untraceable payments.
How to resolve
Ensure that no cash is accepted for orders of €1,000 or above when the customer resides in Spain. Electronic payment methods (e.g., credit card, mobile payment) are recommended.
5. Cash Payment Limit for Non-Residents
Alert message:
Order exceeds €10,000. Cash payment not permitted if the customer is a non-resident.
Why this appears
For individuals not fiscally domiciled in Spain, the legal cash payment limit is €10,000, also under Law 11/2021. This is intended to curb cross-border financial opacity.
How to resolve
Verify the customer's country of residence. If the order total exceeds €10,000, cash payments must be refused and an alternative electronic payment method should be used.
What Happens If These Alerts Are Ignored?
Disregarding tax alerts may result in:
Fines for regulatory non-compliance
Invalidated invoices rejected by tax authorities
Penalties for exceeding legal cash payment thresholds
