The last thing your finance team needs is another AI arms race.
The Financial Times recently reported on a troubling trend emerging across UK and US businesses: employees are using AI to generate fake expense receipts, and it’s working. (Note: The FT article is behind a paywall, accessible to FT subscribers only.)
According to data from leading expense software platforms cited in the piece, this isn’t theoretical anymore – it’s happening at scale.
The Numbers Are Alarming
- AppZen reports that fake AI receipts now account for approximately 14% of fraudulent documents submitted in September 2024 – up from precisely zero last year
- Fintech group Ramp flagged over $1 million in fraudulent invoices within just 90 days
- 30% of financial professionals surveyed by expense platform Medius have witnessed a rise in falsified receipts since OpenAI’s GPT-4o launch
The receipts being generated are frighteningly convincing – so convincing that human reviewers can’t spot them. The industry response has been predictable: fight AI with AI using software that scans for metadata and patterns.
But this is fundamentally flawed. Fraudsters can strip metadata with a simple screenshot. And you’re locked into an escalating arms race where each generation of AI becomes better at fooling detection tools. You’re spending money on technology to combat technology, with no guarantee you’ll stay ahead.
There’s a Better Way: Make Fraud Rare and Obvious
The smartest approach isn’t getting better at spotting fake receipts. It’s reducing fraud opportunities dramatically and making remaining attempts obvious through intelligent integration and policy.
1. Enforce Corporate Card Usage (Eliminate 70-80% of Fraud Opportunity)
Integration makes corporate card policies enforceable and friction-free:
- Auto-populate expense claims directly from corporate card transactions (Amex, Mastercard, Visa)
- Flag personal card expenses automatically for additional scrutiny
- Real-time transaction matching to verify submitted expenses against actual card transactions
Result: Once management mandates corporate cards for standard business expenses, integration ensures compliance. The vast majority of expenses are automatically verified against actual transactions—no opportunity to submit phantom expenses.
2. Contextual Verification for Unavoidable Personal Expenses
For remaining personal card reimbursements (cash-only merchants, emergencies), integrate systems to verify context:
- Travel booking platforms (Concur, TravelPerk) – Confirm trips actually occurred
- Calendar systems (Outlook, Google) – Verify meetings at claimed locations
- Project management tools – Validate legitimate business purposes
- Pre-approval workflows – Require manager approval before expenses are incurred
Result: Even without transaction verification, you create multiple checkpoints that make consistent fraud nearly impossible.
3. Automated Vendor Verification
Integrate with business registries and verification databases to confirm merchants actually exist:
- Companies House (UK) and equivalent business registries internationally
- Google Places API to verify business locations and operating hours
- VAT number verification systems across European jurisdictions
Result: An AI-generated receipt for a fabricated merchant gets automatically flagged when the system confirms no such business exists at that location.
4. Intelligent, Risk-Based Controls
Integration enables tiered scrutiny based on risk:
- Small amounts (under £50): Low friction, post-audit sampling
- Medium amounts (£50-500): Contextual verification triggers automatically
- Large amounts (£500+): Pre-approval required, multiple verification points
When anomalies are detected, the system automatically holds reimbursement, routes to senior approvers, and flags patterns across integrated systems.
Why This Beats AI Detection
| AI Detection | Policy + Integration |
| Arms race – Fraudsters adapt constantly | Eliminates 70-80% of fraud opportunities via corporate cards |
| Circumvented via screenshots | Must fake context across 5-7 integrated systems |
| Reactive – After submission | Preventative – Pre-approval and verification |
| Ongoing AI model update costs | Based on actual bookings, meetings, transactions, registries |
The Bottom Line
AI-generated receipt fraud is costing businesses millions. But the solution isn’t an endless technological arms race.
The solution is to make fraud rare and obvious.
By integrating expense management with corporate cards, travel platforms, calendar systems, vendor registries, and approval workflows, you dramatically reduce fraud opportunities and add verification layers that make systematic fraud nearly impossible.
Will this catch every single fake receipt? No. But it will:
- Eliminate 70-80% of fraud opportunities through corporate card enforcement
- Make remaining attempts obvious through contextual anomalies across multiple systems
- Create an economically unviable risk/reward ratio for would-be fraudsters
Stop trying to spot increasingly sophisticated fake receipts. Start making fraud opportunities rare through intelligent policy and integration.
That’s not an AI problem. That’s an integration solution.
