What you pay for
A flat fee per space
Paid in advance each month. A space added or removed mid-month is charged or credited pro rata.
Model cost, measured
The real cost of model calls, measured on every call and visible in the console, billed back at the plan’s coefficient, in arrears.
A cap per space
Monthly model cost never exceeds the plan’s cap: at the cap, the space pauses until the next month and administrators are notified.
What is not billed
The number of agents
The billed quantity is the number of active spaces. Invite your whole team: administrators and agents have no price.
The number of inboxes
Every inbox of a connected account is covered by the space’s flat fee, each with its own mode.
Conversation volume
No price per conversation or per resolution. Only the measured model cost varies with volume, and it is capped.
Why not a price per resolution?
Most AI support assistants charge per resolution or per seat: the bill follows volume, and you discover it at the end of the month. 0seat charges a flat fee per space plus a measured cost, capped and visible call by call. You know the maximum before you start.

Frequently asked questions
What if I add a space mid-month?
The new space’s fee is charged pro rata for the remaining days, immediately. A removed space is credited pro rata on the next invoice.
What happens when the cost cap is reached?
The space stops calling models until the first day of the next month, and administrators are notified. Your agents keep answering normally in the inbox.
Which currency am I billed in?
US dollars, by ZeroSuite, INC. Applicable taxes are calculated by Stripe Tax from your billing address.
Where do I find my invoices?
In the Stripe customer portal, reachable from the console. Every invoice is issued there with its receipt and number.
Is there a free trial?
No. The card is saved before the first space, and the first month is charged pro rata. You can cancel a space at any time.
Does the price include Chatwoot?
No. 0seat connects to your own Chatwoot instance, whose Community edition is free; its hosting is not in the price. No instance yet? Write to us from the Contact page: we can host one for you, on request.
