Cover image for The AVIS photo capture app

The AVIS photo capture app was built to standardize vehicle photography across rental, leasing, and return workflows. Brights developed a mobile solution that guides users through a structured photo-taking process to ensure consistent image quality and coverage. The app helps employees capture vehicle condition data faster while reducing human error during inspections. We implemented guided capture flows, validation logic, and seamless upload functionality to streamline documentation. The solution was designed to work efficiently in real-world conditions with different lighting, locations, and user experience levels. By automating and standardizing the process, the platform improved operational consistency across teams and locations. The app also simplified review and verification workflows for back-office operations. As a result, the client received a scalable mobile tool that accelerated inspections, improved documentation accuracy, and reduced manual processing effort.
