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!

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.

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 is amazing and the possibilities are seemingly endless!
I can’t wait to explore and expand the functions in my shop through this app.
The support is also amazing - very quick and competent help. Big shoutout to Jason!

So far, go Good!

Mateusz really helped work through a discount that we wanted to run for an upcoming Laboy Day sale. He managed my requests flawlessly and we look forward to executing. I believe this app will also help with some other components that we will want to run in the future as well!

Bravo!

Setup was straightforward and intuitive. Support was fast and genuinely helpful.

Jason Was a really great help with setting it up. Now I can use a discount that only applies to 1 item in the cart.

Lovely app, it's pretty powerful and useful. Support is also great!

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.
