Migrating to Checkout from BigCommerce and Magento duty tax apps
We will sunset the BigCommerce and Magento Duty Tax apps September 30, 2025. If you are using one of these apps, you will need to migrate to Zonos Checkout.
What Checkout offers
Checkout delivers a seamless international shopping experience with real-time currency conversion to 130+ countries, and 23+ local payment methods. Checkout handles upfront duty and tax calculations while managing all compliance requirements and tax remittance behind the scenes. Our advanced fraud protection helps safeguard your business from fraudulent transactions. This allows you to offer your global customers the same smooth experience your domestic customers enjoy, while eliminating the complexity of cross-border commerce and reducing your accounting workload.
Optional: Power your domestic checkout with Zonos
While not required, Checkout gives you the option to power your U.S. checkout with Zonos. When Zonos Checkout is used for U.S. transactions, Zonos takes care of:
- Sales tax calculation, collection, and filing in all states
- Full compliance with state nexus rules
- Reducing your accounting work and risk of tax penalties
