Hello @Noahd ,
To be honest, everything depends on the industry you are in, business model you plan to use, products you will sell and your product acquisition channels.
The easiest way to understand how Shopify works is to try it yourself. During the trial period, you’ll gain some experience in setting up, managing, and estimating your potential costs based on your needs. To continue selling after the trial is over, you’ll have to choose one of the subscription plans.
Best regards,
Anastasia
