FC Functions Creator & Scripts

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!

The app works very well and has been reliable for my promotions. One improvement that would add real value is the ability to apply Buy X Get Y offers across multiple sets. For example, if the rule is “Buy 2 of Product X → Get 1 of Product Y,” it would be helpful if buying 4 units of Product X automatically triggered 2 rewards instead of only applying the offer once.

This adjustment would make the promotion logic more flexible for stores that rely on volume-based deals. Everything else has been smooth so far, and adding this option would make the app even more complete for everyday use.

App works very well and Reymar was very helpful! Would recommend using this app!

Precies wat ik zocht! Ik kan zo mooi bepaalde betaalmethodes verbergen voor een specifiek land en ook de volgorde aanpassen per land.
Mijn vragen werden ook snel via de chat beantwoord! Goede service dus.

Very helpful support! This app is 100% working and is very useful to my discount conditions.

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 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!

It is easy to use. Although there is a little bit of issue, Jason responses quickly and he is very supportive. Recommend.
