How Supplemental Damage Estimates Work

A supplement documents additional collision damage or required repair operations discovered after the initial estimate.

Why supplements happen

Initial estimates are often written before a vehicle is fully disassembled. Once repairs begin, hidden damage, additional labor operations, scans, calibrations, sublet work, or manufacturer-required procedures may become apparent.

What a strong supplement documents

  • Newly discovered physical damage
  • Required labor operations and repair procedures
  • Parts, materials, scans, calibrations, and sublet work
  • Photos and teardown documentation
  • Manufacturer repair information when applicable
