MISMO Body Care review for FC Functions Creator & Scripts

Sept. 29, 2025

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.
