Here's how billing units work at Brarista.
Chatbot: a chat is counted each time a customer sends a message to the bot. If a customer asks three questions in one visit, that counts as three chats.
Fitting quiz: a completed quiz counts as one charge, when the customer reaches their results page. Opening the quiz and leaving partway through is not charged, and redoing the quiz in the same session is not charged again.
Your monthly subscription includes a set number of chats. Your agreement states the number included and your overage rate. Once you pass your allowance, additional chats are billed at that rate.
