Propertyware does charge an access fee, you are correct. Additionally, they offer a licensing agreement where their customers can provide API keys to consultants to help them build out their tool(s). We are one of those consultants.

As far as who assumes the access fees, they are managed strictly by our customers and we have no pass-through pricing on that side. Our pricing is solely based on our own costs, infra, value, etc. All of our customers get access to all of our integrations (current and future) as part of our standard pricing model.
