done. is a billing platform for AI agent builders. It takes signals from the product and other systems, evaluates them over time, and finalizes them into a single auditable billable outcome.

As AI products move from seats and usage toward outcome-based pricing, billing needs more than raw events. done. keeps product behavior, billing logic and invoices consistent, so teams can show what became billable, why it became billable and what evidence supports the charge.
