This app is UNBELIEVABLY powerful. It has generated us a significant amount of additional revenue in a short amount of time, and also helped us solve operational challenges. The app developer is very responsive. HIGHLY RECOMMEND!

Good!
— TrendFit_23
Amazing and powerful app. Combines the need for multiple apps into one easy to use app. Very efficient customer service. Impressed!
— SoftwareCW
5 Stars - Exceptional App and Unmatched Support! I cannot speak highly enough about Checkout Buddy! This app has been absolutely instrumental in creating all the intricate customizations I needed for my small business. The app itself is intuitive, powerful, and incredibly easy to integrate with my Shopify store. But what truly set this experience apart was the support – it’s hands down the best I...
— Montana Mex
This app has really great functionality options! Really useful for creating custom prompts at checkout that I couldn't do with other apps. Kyle was really helpful and so quick at replying to me when I had questions.
— Mine & Yours
Checkout Buddy unlocks the true power of Shopify's Checkout Extensibility without the dev effort. The best part is that it functions as a utility tool unlike most other apps that sell you on fancy marketing promises but then shackle you into opinionated workflows and annoying/confusing subscription plans. Extra points to Kyle for being ultra responsive with support and even squeezing in new featur...

This app is fantastic, as is Kyle's support.Comes with a lot of features and even translation options, which is great in our case as we have a multi-lingual store.
— Carmelo A Bentley
Kyle is super quick to respond to emails and has made the whole process super easy! Highly recommend
— WorkwearHub
Great app to customize the checkout. Comes with a lot of features and even translation options, which is great in our case as we have a multi-lingual store. Support is really helpful and replies to questions really quickly. HIGHLY RECOMMENDED.
— UNISTELLAR EUROPE
This app is amazing thanks to the incredible developer Kyle. I've had several emails back and forth with Kyle asking about features and how to do things and he's responded incredibly quickly and helpfully. What a delight! The app has already paid for itself just by adding one item in a cross sell block in the checkout. I tested Shopify's new checkout blocks app but this one was way more intuitive...
— Ridge Merino
This app is amazing and allows us to add everything we want to the checkout since upgrading to checkout extensibility. We had 2 feature requests that were need to suit our date picker. Kyle updated the app within a day with the features couldn't expect anything more
— David Austin Roses - UK
This app is fantastic, as is Kyle's support. Not only has it helped us add new functionality - but it continuously helps us evolve and create the best checkout experience for our customer.
— FreshCut Paper
This app is very hard to navigate, I wish I could say setup was easy but it is not. I also reached out to support with one of the settings not seemigly working, no response after multiple days.
— Sparkle
While upselling and offering free gifts can boost sales, these tactics can be overwhelming or even intrusive for customers. If not implemented carefully, upsell prompts could distract from the main purchase or make customers feel pressured into additional purchases they may not want. This might lead to dissatisfaction, especially if customers feel like the checkout is too focused on selling them m...

Everything is 'Only on Shopify Plus' - So it's pretty pointless, even if it is offering a 'FREE' plan... Unless, you have shopify plus!
— Vita Sharks
Solves most of our problems in customizing our checkout :)
— Slettvoll Møbler
Amazing app with LOTS of functionality. I've contacted support a few times and Kyle has been quick to respond and quick to find a solution for my requests. Highly recommend for any checkout customizations!
— Global Healing
Fantastic app. Easy to implement, use, and understand. Good support too!
— Omni One by Virtuix
Checkout Buddy transformed our Shopify checkout, offering great customization options. The standout feature is the developer team's support. They readily added custom features we requested, making the app perfectly suit our needs. Highly recommended for an enhanced checkout experience!
— AUTEUR
Impressed by the prompt and competent responses to questions. This app is a must for Shopify Plus, and I can wholeheartedly recommend it.
