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!

Just installed and it is intuitive to use. My request ended up being a bit more complicated than most but the support from Mateusz was absolutely excellent.

Update - just used again and have to say the customer service is second to none.

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.
