Does anyone know how Pricing Plans and Users works?

Does anyone know how Pricing Plans and Users works?

First off, I just want to say I asked Zoho Support directly if they could help, and I didn't get a useful response.  So I'm asking here.

I am trying to set up my Pricing Plans for my SaaS solution I'm creating in Zoho Developer.

This may sound dumb, but I really can't figure it out.

Let's say I have an SaaS app.  I want the monthly cost to be $80 a month for 5 users up-front.  And I want to give them the option to add additional users for $10 each.

Can I do something like this?
