Repair manuals may be tied to payment milestones, but milestones must correspond to objective documentation. The contract should specify the required tool lists, training records, repair documentation, escalation contacts, and reviewers; release the related payment only after approval. Splitting payments without evidence conditions will not prevent a lack of diagnostics, documentation, or safe-work capability after dealers sell vehicles. High-voltage and safety-related work must be performed only by personnel qualified under local requirements.
