APEX benchmarks measure what enterprises actually care about. We built APEX-Accounting with @RampLabs to see if agents can handle a real company's books. Agents work the ledger in QuickBooks, tie it to bank statements in PDFs, chase figures across spreadsheets, and judge what is a real discrepancy. Results are graded against 2,186 criteria created by real accountants. See full leaderboard:
