Here are my questions:
1. As an AI agency, part of our billing is for token usage by the tools that we build for clients where we pass on that cost, usually with a markup, to our clients. Is there a solution for bringing in the token usage for a month from, let's say, OpenAI under a specific API key into AgencyPro and marking it up by say 2x, and then billing for that?
2. We also have retainers, project fees, and ongoing maintenance fees that need to be properly billed to clients along with the token usage fees. Can a bill be dynamically calculated and sent at set intervals like one month, or one quarter, including all of those types of fees?
3. Does each workspace get its own custom domain? Or, is it just one custom domain per account?
4. What's the cost to add more user seats and/or more workspaces?
