SMART Functions Creator

Great extension if you want to solve small and tricky issues which make a lot of impact. Btw: the support is more than great. Can absolutely recommend!

Very well done! This app opens a lot of possibilities. You can also replace a few of your paid apps using only FC Fonctions. The support is also very responsive. Looking to create a tricky script? Use the chat for quick and professional support! This app is a must on your store!

Amazing experience using the service I recommend to anyone very helpful and professional throughout my query.

brilliant customer service, great app

柔軟なディスカウント設定を行うことができ、とても良かったです。
サポートも丁寧で大変助かりました！

This app really helped us with a critical shipping problem for our store. Reymar took the time to understand our issue and even went as far as setting up the function that we needed. Problem solved! Highly recommended.

This app does exactly what I need it to do. I tag items added to the cart via my custom-built bundle builder with a line-item property. I was able to build a custom discount function in the app that automatically applies the appropriate discount based on the condition and property. Support (Reymar) helped me set up the properties and get it up and running. He was super helpful and quick to help! Would recommend!

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.

Amazing support and super flexible app

We recently switched to Functions Creator, and it’s been a huge improvement. The app is incredibly flexible thanks to its use of the latest Shopify API.

What really made the difference, though, was the outstanding support from Mateusz. He spent a lot of time helping us with a fairly complex request and truly went the extra mile to make sure everything was working as needed. It’s rare to get this level of dedication and responsiveness.

Highly recommend the app, especially if you’re looking for something future-proof with real support behind it.
