King Checkout Validation

Support was responsive and quickly implemented support for validating a new early access Shopify field to collect a required ID number in certain countries. Really appreciate the fast turnaround.

App funktioniert wunderbar, der Support ist schnell und zielführend, haben 2 Funktionen angefragt, die innerhalb kürzester Zeit einprogrammiert wurden (Rules für billing address, war vorher nur für shipping verfügbar).

Great support and service. Gordon is a major help!

Exactly what we we're looking for, since we can't use the checkout blocks as we're not on Shopify Plus.

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.

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

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.

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