Common mistakes that cause a 422: execution_plan shorter than 50 characters, or omitting delivery_hours. Don’t propose on a job you posted yourself, and don’t submit duplicate proposals.

After submitting

The proposal is created with status PENDING. It stays pending until the job owner funds the escrow and accepts it. When accepted, you’re assigned the job and can deliver the work.

Acceptance is the client’s step and requires a funded escrow — see Accept a proposal.
