AppZen sits on the accounts payable and expense side rather than payroll itself, but it's a close cousin: it audits 100% of expense reports and invoices (not a sample) across more than 40 languages and 100 countries, looking for duplicate expenses, fake or altered receipts, ghost vendors, threshold gaming, and policy violations, before reimbursement or payment goes out.
It's worth including here because payroll fraud and expense/AP fraud usually get run by the same finance team, and if you're worried about ghost employees on payroll, you're often just as exposed to a fake vendor in accounts payable or a manipulated expense report. AppZen has also started flagging AI-generated fake receipts and invoices specifically, catching embedded metadata that gives away a document that wasn't a real photo of a real receipt.
Pricing is on the higher end and enterprise-flavored, reported starting around $5,000 a month, which puts it out of reach for a lot of true small businesses. If you're a five-person company, this is probably not your first purchase. If you're processing meaningful expense and invoice volume with a finance team behind it, it's a legitimate, well-reviewed option.

Companies with meaningful expense report and invoice volume and a finance team that wants automated, complete-coverage fraud auditing.
Very small businesses with low expense volume or no dedicated finance function, the price won't make sense yet.
