Understanding Plasmic pricing structure

Impressed with plasmic, I am not clear about how the pricing works, could any one explain?

Let us know if you have any specific questions: https://www.plasmic.app/pricing

For example If I built an ecommerce site front end for a client with
• shopify api as backend
• 20,000 signed up users ( 30% active )
• 1 million site visits/month
what will be my monthly cost for using plasmic

It would probably land you in ~Scale but please feel free to reach out to sales@plasmic.app and we can get you a better quote

then it must be hard to go with clients …
