AppZen

Pros

Reviews every single expense report and invoice, not a sample, closing the gap manual audit leaves open
Actively detects AI-generated fake receipts, ahead of where a lot of competitors are
Strong international language and country coverage

Cons

Starting price around $5,000/month puts it out of reach for true small businesses
Focused on expense/AP, not payroll runs themselves, it's adjacent coverage, not direct
Enterprise sales process, no self-serve option

Trustpair

Pros

Validates account ownership, not just account existence, which is the check that actually stops diversion
Continuous monitoring catches bank-detail edits between onboarding and payment
The $1M liability backstop puts money behind the accuracy claims

Cons

Enterprise-only pricing walls off the SMBs who get hit by the same scam
Value concentrates in companies with large vendor files, at 50 vendors a callback policy does most of this for free
Deep ERP integration is where the product shines, so lightweight accounting stacks see less of it
