BoomGate: Checkout Validation

Really useful app. I needed a pretty specific checkout validation based on customer metafields and BoomGate did exactly what I needed.

The setup is straightforward and the support has been excellent. They replied quickly, understood the issue properly and showed me exactly how to structure the rules.

Great value, especially if you’re on Shopify Basic and need more control over checkout. Definitely worthwhile.

I rarely leave reviews, but this app and the team behind it truly deserve it.

I needed a very specific checkout validation for the xConnector integration and Cargus pickup points in my Shopify store. The team implemented the update I needed, and their AI Assistant helped me build the validation rules step by step. During testing we discovered a few edge cases, and together we managed to solve them.

What impressed me the most was their responsiveness and genuine willingness to help. They listened to my feedback, suggested different approaches, and helped me find the best solution for my specific use case.

Excellent support, a powerful app, and a team that genuinely cares about solving customers' problems. Highly recommended!

The team are amazing. I had a shipping issue and they created an update to fix things for me. Efficient, speedy, excellent communication. What more can I ask for? Problem solved within an hour. Highly recommend.

I just installed this app to protect against really annoying orders from stolen credit card testing fraudsters which have started coming through recently.

Because we only need one validation to protect us completely from this scam we are on the free plan - hence I though it only fair to write a 5-star review.

It works beautifully, the AI got the rule right first time and all tested - flawless. Interestingly the app was recommended by Claude. And now by Oui Chef;)

Very easy to use and set-up rules

Nutze die App für meinen Mindestbestellwert. Genial, dass es das gibt.

Und der Support ist Weltklasse! Hatte ein selbst verschuldetes Problem. Am Ende war es nur ein Häkchen, was ich entfernen musste. Der Support hat super geholfen. Danke.

We use BoomGate to control exactly which orders can pass checkout, and it’s been excellent so far! The rules builder handles real‑world cases like min/max quantities, customer tags, and product restrictions without slowing checkout. The interface is clear, error messages are easy to customize, and support is fast and genuinely helpful. Highly recommended.

I have tried EVERY SINGLE ZIP VALIDATOR APP and this is the only one that can block a purchase based on more than one condition (and at a reasonable rate too!) We've had customers using the wrong zip codes to hack lower delivery fees for Local Delivery and this app just saved our butts!

Amazing app! needed an app that prevent customers from order products that aren't allowed to ship to California, in checkout if customer added CA as shipping state, they are getting a msg saying they have to remove that item. But still let them order the rest. App has Lots of helpful options. Recommended 100%

We are using this to limit the length of the "Company" field in the Checkout - works well! :) It only runs the validation asynchronously whenever the shipping address is complete though - if I could wish for one thing it would be a more snappy UX (e.g. just limiting the `max` of the HTML input directly)
