Employees are using AI to generate fake expense receipts. Leading expense software platforms report a sharp increase in AI-created fraudulent documents following the launch of improved image generation models by OpenAI and Google. AppZen said fake AI receipts accounted for 14% of fraudulent documents submitted in September compared with none last year. Ramp flagged more than one million dollars in fraudulent invoices within 90 days. About 30% of financial professionals in the US and UK surveyed by Medius reported seeing a rise in falsified receipts after OpenAI released GPT-4o last year.

SAP Concur processes more than 80 million compliance checks monthly and now warns customers to not trust their eyes. The receipts include wrinkles in paper, detailed itemization matching real menus and signatures. Creating fraudulent documents previously required photo editing skills or paying for such services. Free and accessible image generation software has made it possible for anyone to falsify receipts in seconds by writing simple text instructions to chatbots.
