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 enterprise-flavored, reported starting around $5,000 a month, which puts it out of reach for most true small businesses. Think of AppZen as the ceiling of this category: complete, autonomous AI audit of every expense and invoice, priced for a company that already has a finance team. The SMB-accessible version of that same audit layer is Ramp or BILL, real duplicate and policy checks built into a free or low-cost spend/AP tool. Graduate to AppZen when your volume and headcount actually justify a dedicated audit engine; until then it's a name to recognize, not a shortlist item.
