Invoice fraud in recruitment agencies: what staffing finance teams should watch for
Recruitment and staffing agencies process an unusually high volume of invoices relative to their size, with new suppliers and contractors onboarded constantly. That combination makes the sector a frequent target for invoice fraud — here’s what that looks like in practice.
Why recruitment is exposed
A staffing agency might onboard a new contractor or supplier every week, each with their own invoicing and payment details. Fast onboarding is a genuine business necessity in recruitment — but it also means there’s less time to build up a verified history with any given supplier before invoices start being paid, which is exactly the gap fraudsters look for.
Where it tends to show up
- New-supplier impersonation — a fraudster sets up as a plausible-looking contractor or sub-agency with no real trading history, then invoices for placements or work that didn’t happen.
- Mandate fraud on existing contractor relationships — a routine “my bank details have changed” message from what looks like a contractor you’ve paid for months.
- Amount inflation on genuine invoices — a real contractor’s invoice quietly billed at a higher rate or for more hours than agreed, relying on high volume to avoid a closer look.
What to check before the first payment
For any new supplier or contractor, confirm bank details by phone before the first payment goes out — not after, when there’s already a relationship and a sense of momentum that makes it easier to wave a later detail change through. Keep new-supplier checks consistent even when volume is high and the pressure is to onboard quickly; that pressure is precisely what fraud relies on.
High invoice volume is the recurring theme in recruitment fraud, and it’s also why manual checking doesn’t scale well here. A new-supplier check and an amount-anomaly check that take thirty seconds each are easy to skip on the fortieth invoice of the day — which is the specific gap automated checking is built to close.
