Set up GoPay integration

GoPay is a payment collector operating mainly in EU. LTTR/SHOP supports GoPay as an optional payment collector, so your customers are not asked to pay VAT in select intra-EU sales. On the other hand, you need to account those sales individually instead of benefit from the seamless accounting when FastSpring is used.

When to use GoPay

We support GoPay as a payment collector only for EU sales when the sale is neither a subject of a VAT nor a reverse charge applies; for all other sales, FastSpring is used.

You can consider enabling GoPay only if all the following conditions are satisfied. In all other cases, keep GoPay disabled.

• You are based in EU.
• You are not a VAT payer in your home country.
• You chose to apply MOSS exception for small businesses to charge your home country VAT rate instead of the customer's country rate.
• It is ok that we issue invoices on your behalf.
• You are open to account all the GoPay sales individually.
• Your local law allows this option.
