Milestones are the payment units inside an OpenTrain contract. Each milestone has an agreed scope, amount, and status. Employers fund milestones before work starts, and AI trainers request payout after completing the work. Use this page as a shared status reference. For the step-by-step workflow, use the role-specific guide for your account type.

How the payment flow works

1

Employer creates and funds a milestone

The employer defines a work unit, amount, and optional due date. Funding the milestone charges the employer’s payment method and marks the milestone Active & Funded.
2

AI trainer completes the work

The AI trainer sees the funded milestone in the contract view and completes the agreed deliverable.
3

AI trainer requests payout

The AI trainer clicks Complete & Request Payout from the Contract tab. The milestone moves to Pending approval while the employer reviews the work.
4

Employer approves and releases payment

The employer clicks Approve & Release Payment. OpenTrain marks the milestone Paid and starts payout to the AI trainer’s connected bank account.

Disputes

If there is a disagreement about whether work meets the milestone criteria, the milestone may enter a Disputed status. If you reach a point where you cannot resolve a dispute directly with the other party, contact support@opentrain.ai for assistance.
