King Checkout Validation

Incredible service. Had the app for 5 minutes, and needed a custom feature/rule which wasn't included. Gordon from support created my new feature within 30 min.

This app really saved us. We have an integration with SAP, and some fields have character limits that can’t be changed. This app solved that issue, and we also used it to block sending orders to certain islands via ZIP code rules — which works perfectly. I highly recommend this app. We’re running it on eight stores now.

Very nice app - and especially very good and fast support. Thanks.

Danke für die Hilfe vom Support, macht bis jetzt einen guten Eindruck. :)

This is a fantastic product and the developer is extremely responsive and helpful! Great app!

Created a new functionality, the day after reaching out on chat for advise on how to setup a feature, and testing the initial solution.

The app does its job smoothly and the support team is very quick to answer inquires and to fix issues. Gordon was a great help with the problems we have encountered.

Very good app for checkout validation, and the support team is very responsive.

Great app and best support!

Very happy with the app for now! We installed it and works really easy. Also very quick customer service for any question!
