AI-Generated Receipts Surge, Now 14% of Fake Expense Documents

Expense platforms are shifting to AI that checks contextual signals after basic metadata screening proved easy to evade.

Overview

  • Software provider AppZen said AI-generated receipts made up roughly 14% of all fraudulent expense documents it saw last month, compared with none a year ago.
  • Expense tools showed highly convincing examples to the Financial Times, with paper wrinkles, accurate itemization and signatures that can fool human reviewers.
  • Vendors say simple metadata scans are easily bypassed by photographing or screenshotting generated images, pushing adoption of deeper automated analysis.
  • Detection now incorporates contextual checks such as repeated server names, suspicious timestamps and alignment with an employee’s trip data, according to Ramp.
  • SAP reported that nearly 70% of CFOs suspect employees are trying AI to falsify expenses and about 10% are certain it has happened, as fraud experts warn the barrier to creating fakes is near zero.
