More Control for VAT-Exempt Orders at Shopify Checkout

TL;DR: This Shopify VAT-exempt checkout feature lets you require billing and shipping address consistency after VAT validation. You reduce risky orders while keeping the normal checkout flow smooth.

• Address control where it matters: The rule only runs after successful VAT validation.
• Low-friction buyer experience: If billing equals shipping, checkout continues as normal.
• Clear in-checkout messaging: Buyers instantly see why checkout cannot continue.
• Built for B2B operations: Fewer manual checks before invoicing VAT-exempt orders.

If you sell B2B in Europe, this scenario is common: a buyer validates VAT, then uses a different billing address in the payment step. That creates uncertainty, extra support tickets, and manual order review work for your team.

With this setting in the EU Tax Exemption app, you can enforce address consistency in Shopify checkout when VAT exemption is requested.

Why Address Consistency Matters in Shopify VAT-Exempt Checkout

Many merchants want more confidence in VAT-exempt orders, especially for higher-value B2B transactions. Without clear guardrails, teams often pause fulfillment to verify customer details manually.

This feature works alongside automatic VAT validation and cleaner VAT number data for invoicing, so your process stays both compliant and fast.

How the Billing and Shipping Match Rule Works

1. The buyer enters and validates a VAT number.
2. The buyer continues to payment.
3. If a separate billing address is entered and differs from shipping, checkout is blocked.
4. If billing matches shipping, checkout continues.

The rule is strict only after VAT validation is successful.

Allowed vs Blocked Scenarios

Who Should Enable This

This is a strong fit for stores that:

• Sell B2B with VAT-exempt pricing.
• Need a stricter checkout policy without custom development.
• Want to reduce manual order screening before invoicing.
• Already run VAT validation in Shopify checkout.

It also complements a stronger B2B checkout flow and your reverse charge VAT process.

How to Enable It

1. Open the checkout extension settings.
2. Enable Block if billing differs after VAT validation.
3. Test one allowed scenario and one blocked scenario before going live.

No custom scripts or checkout rebuild needed.

FAQ

Will the Pay button disappear?
No. Buyers can still click Pay, but checkout will not proceed when the rule fails.

Does this affect regular B2C orders?
No. This logic is tied to VAT validation flow.

Can billing and shipping still differ for non-VAT checkout?
Yes. This feature targets VAT-exempt checkout control.

Can we test this safely first?
Yes. Activate it in test mode and validate both pass and fail scenarios.
