I was looking to purchase tier 10 and see that you get 300 users/companies, 1000 image creations, 2,500,000 credits. this sounds like a lot but as an agency if I have 300 companies that is only 3 images and 8300 credits per company. I tested 2 posts and the credit usage was 3800 credits. For two only two posts. There is no way a client can use this for a daily post in those limits. Can I purchase more credits? I saw an integrate for the openai api (would this use credit from my account?) I like the product a lot but I am trying to understand how to make it work and not frustrate clients.
