SMART Functions Creator

Works perfectly with any combination or conditions you need to setup your discounts for.

This app makes it incredibly easy to build advanced Shopify Functions no coding needed! I’ve used it to set up tiered discounts and promos that would’ve been impossible with standard tools. The interface is intuitive, and everything integrates smoothly with my store.

What really impressed me was the support: super fast, knowledgeable, and genuinely helpful. They solved my issue in no time and even offered suggestions to optimize my setup. Highly recommended!

This app has completely changed what I can do with Shopify. The flexibility is next level — I’m now running discount setups that I thought just weren’t possible. For example, I can tag items added via my bundle builder with a line-item property, and the app’s lets me build a native discount function that automatically applies the correct deal based on the condition/property. It works seamlessly and has opened up so many new promo options for us.

Even the basics are useful — like reordering shipping options so customers see our express upgrade first instead of defaulting to free. Small tweaks like that are impossible in Shopify by default, but Function Creator makes it easy.

On top of that, the support is excellent. The team genuinely goes above and beyond to help you get things set up and answr questions quickly.

If you’ve ever been frustrated by the limitations of Shopify’s standard discount engine, this app is a must-have. And that's just discounts, I'm still to explore the other types of functions.

This app has been extremely helpful for us in creating offers that were landing page specific that did not affect the global site. We were unsure on how to work the app itself and the app team (in particular Mateusz) helped us build our first offer and get it live. Thank you very much for your support so far!

Very happy with the support given and overall experience. Congrats to Reymar for always being there for us.

Great little app that does bundle for a fixed price! better than many other paid app that can't get the right idea! on top of that it does calculation automatically in the cart!!! function only few has!

Their customer service is amazing. I've been back and forth with their Live Chat function and every time I get the same person so they remember what the original issues are. I recommend this app.

Incredible level of support. Had very knowledgeable support agent put a complex shipping discount together within 15 minutes, works flawlessly. Highly recommended!

Amazing app! Discount works on headless storefront which is exactly what I need! Thanks to Reymar
