We’ve run several discounting functions through this app, including more complex logic that we previously handled with Shopify Scripts. As we transition fully to Shopify Functions, FJ makes it easy to manage and maintain these promotions without needing ongoing developer support. The interface is straightforward, and it gives us confidence that we can continue evolving our discount strategy without custom code. It’s been especially helpful as Scripts are deprecated and Functions become the standard. Great tool for teams that want powerful discount logic without adding too much dev overhead.

If you need serious control over discounts, Function Junction is the way to go. It unlocks advanced Shopify Functions without sacrificing performance, and it’s become our go-to solution for complex promo rules.

Function Junction made our transition off Shopify Scripts painless. The app handles sophisticated discount logic cleanly and integrates seamlessly with our existing workflows. Solid product and excellent reliability so far.

Function Junction has been a great replacement for Shopify Scripts. It gives us far more control over complex discount logic while staying fast and reliable. Setup was straightforward and it’s become a core part of our store’s promo stack.

Incredibly helpful with getting the app installed and ready in-time for our sale (with 1 day notice)! Performance of the app has been fantastic.

We use this app all the time to run our promotions. Easy to use. The team is responsive and helpful.

Function Junction made transitioning off Shopify Scripts super easy! We were able to move away from our complex scripts much sooner than expected—and without any major development costs. Setting up custom bundle discounts was incredibly straightforward, even with our more advanced use cases. The Presidio team went above and beyond, guiding us through the entire process and even adjusting their app to fit our needs. One of the best experiences I've had with an app developer!

This app is an outstanding alternative to Shopify Scripts and surpasses any other discount app available on Shopify. It’s extremely user-friendly, and when building more complex setups, the support team is exceptionally helpful. Highly recommended!
