App does exactly what it says it will do and let you create essentially any custom discount that you want without needing to upgrade your shopify plan. Also Mira was extremely helpful in getting our custom discount setup to the exact specification we needed. Was an easy white-glove process, and would highly recommend!

Excellent app and outstanding support. SMART Functions has been a great fit for our Shopify store and has given us the flexibility we needed to build more advanced discount logic without unnecessary complexity. It has been reliable in our experience and works very well with our setup. A special thank you to Reymar for his exceptional support. He has helped us several times with technical questio...

I'm not exaggerating when I say that this app has the best onboarding and customer service team I have ever experienced. I'm still not sure whether I'm chatting to a real person or an AI, but whichever it is, they managed to build/solve an incredibly complex discounting method for us, and all within minutes. If this is AI, it's above and beyond anything I have used from the main players. If it's r...

Great app for creating custom Shopify functions! I was able to set up a specific shipping rule that wasn’t easy to achieve with Shopify’s built-in settings. The customer support is excellent, too. Jason responded within minutes and was incredibly helpful, friendly, and understanding. It’s refreshing to receive such personal and attentive support. Highly recommended!

I needed some help so contacted support. They provided a first class service, helpful and understanding. Highly recommend.

Der Support von Mira hat mir sehr geholfen, eine individuelle Prüfung für Rich Product Options einzurichten. Kunden müssen mindestens einen Artikel aus zwei Auswahlgruppen auswählen, ohne dass eine bestimmte Kategorie verpflichtend ist. Genau so wollte ich es haben, und in meinem Test funktioniert es wie gewünscht. Vielen Dank an Mira für die geduldige Unterstützung!
— AQUALITH
Great tool, allows a lot of customizing for discounts and payment. Support is extremely responsive and quick and really understands the problem and comes up with a custom solution in no time! Highly recommended!
— FRED & FELIA
This app can do SO much. It's beyond me to understand it all BUT the AI chat is amazing at helping. It has also added a duplicate feature which I did request (not sure if this was due to many requesting the same thing but I'm so pleased nonethless). I use SMART discounts and now SMART functions makes my bundles combine and give the prices I wanted without the expense of another app. Plus it even a...

Once again Mira saved the day for me! Great support!
— Party City Austin
We needed a fairly complex discount solution for a custom Shopify Bundle Builder, involving line-item properties, quantity thresholds across multiple products, and exclusions for specific add-ons. I was expecting hours of configuration or custom development, but the entire process was ridiculously straightforward. A huge shoutout to Mira, who was absolutely fantastic. I simply explained what we...
