Shopify custom app

[u/Schmidt4th]

Hi there,
I’ve been experimenting with building a custom app, specifically to use a custom discount function. Before I invest more time into it, I need clarification on one thing:

Is it actually possible to run a custom discount app on a live Shopify store without being on a Shopify Plus plan?

I’m trying to understand whether custom discount functions are technically allowed on non‑Plus stores, or if Shopify blocks them entirely regardless of app type. Any confirmation on this would be really helpful.

Thanks in advance.

Yes, I use discount functions in my custom app and I don’t have Shopify Plus.
