If you choose to integrate Brizy Cloud using our APIs (see step 2.1 from the on boarding process) you can use your own billing system. In this case you can include brizy PRO for free in your products, or charge $10000 per license, it doesn't matter. Your call.
If you don't have a billing system, we are offering a white label payment process integration via Stripe (see step 2.2 from the on boarding process) where you can control the prices (per month, per year and even per day) from your Stripe Account.
All this will be discussed in the onboarding process.
