What merchants think

Feedback submitted

Merchants use this app to run complex discounts and promotions beyond Shopify’s native tools, including advanced conditions, stacking, tiered and BOGO offers, and “only 1 item in cart” rules. It’s often a direct replacement for Shopify Scripts and also handles niche shipping and delivery logic. Many find it intuitive, reliable, cost-saving, and highly praise the fast, expert support for building and optimizing functions.

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

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 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!

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.
