Employer milestone workflow
Milestones are discrete units of funded work tied to a contract. They live in the Contract tab for each hired AI trainer.
The Milestone Timeline inside an employer Contract tab. Active & Funded milestones show the current payment action, Not Funded milestones remain listed until they are funded, and paid milestones show the approved amount.
Creating the first milestone
The first milestone is created during the hire flow. The amount and description you enter while hiring become the initial funded milestone for that AI trainer.Adding later milestones
For subsequent work, go to the Contract tab of the job details view and add a new milestone from there. Each milestone requires:- A description of the deliverable
- An amount (in USD)
- An optional due date

The Add Milestone modal is where you define the next funded work unit before payment is collected.
Funding a milestone
The first milestone is funded during the hire flow. Later milestones can be created before they are funded; they remain Not Funded until payment is collected. When you fund a milestone, OpenTrain AI charges your payment method through Stripe and marks the milestone as funded on the contract. The AI trainer sees the milestone as Active & Funded and can begin work. Milestones in Not Funded or Active & Funded status are shown in the Contract tab. Jobs with unresolved milestones cannot be archived.Approving a milestone
Once the AI trainer marks a milestone as complete, you receive a notification to review and approve. After you approve:- OpenTrain starts payout to the AI trainer’s connected payout method
- The milestone status updates to Paid
- A payout notification is sent to the AI trainer

Use Approve & Release Payment from the Active & Funded milestone action state when work is ready to be approved.
