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.

Codelet is a usage-based and credit-based billing infrastructure for SaaS and AI products. Meter events, track usage, and automatically invoice customers through Stripe or Paddle.

Built for developers and SaaS companies that need flexible drop-in billing models beyond fixed subscriptions. Simplify your monetization workflow and focus on your product.

Easily create and update pricing and avoid building a complex billing system.

Use AI agents to set up and manage your Codelet account with agent skills, SDKs and API.
