Users:
• Reception agent: describes and records information about the vehicle and the claim, then assigns the mission to the field agent.
• Expert: receives information related to the claim, takes photos of the claim, receives the quote from the client's mechanic, then forwards it to the estimator, then takes photos after repair.
• Estimator: receives the repair quote from the client's mechanic. If the quote seems coherent, they send it to the manager for validation, otherwise they re-evaluate the quote before transmitting it.
Back-office Manager: sends validated reports to the insurance company and monitors the file, receives photos after repair for comparison.
• Management: validates or refuses quotes, visualizes the lifecycle of files: number of quotes received, validated, and refused or pending, number of missions received from the insurance company, status of fees paid or awaiting payment.
