Excellent product and excellent support. Many of our customers use freight-forwarding service and will forget to enter their Suite numbers in shipping addres causing the orders to fail, be sent back. Result is no sale and loss of initial shipping charge. No longer have this problem thats to King checkout

— Nemechek Protocol

The app itself is feature-rich and has been very helpful for managing shipping restrictions and preventing problematic orders. It's easy to use, flexible, and backed by a team that truly cares about its users.

— Even Realities Global

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.

— Retro

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

— The English Hatter

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).

— Tennis-Point

Great support and service. Gordon is a major help!

— Juvenon

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.

— Colorful Standard

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

— Pilgrim

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

— Aqua-Birne

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.

— Gorilla Sports

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

— Stur Drinks

Great app for controlling the checkout process with custom rules! We mainly use it to block specific ZIP codes and set character limits in fields before the data gets pushed to Shopify — and it works exactly as needed. What really stands out is the support team. When we first ran into an issue with ZIP code blocking, they quickly developed a new feature that supports both prefix and suffix rules....

— GS-DEV-Stage

Great app and best support!

He is an exceptional developer—truly the best. When it came to the new Shopify field, he resolved it immediately. His expertise and efficiency are truly remarkable. Once again, I would like to express my deepest gratitude for your support and dedication. Your contributions have been invaluable, and I hold your work in the highest regard.

— VIVAIA Korea

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

— A.Kjærbede

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.
