Root Operational Bottleneck
Bank fees are read off fifteen monthly statements and typed into a fee analysis workbook, so a rate change on one account is only caught if someone compares this month's line to last month's by eye.
Control Hazard & Audit Exposure
Fee creep accumulates across accounts because charges are booked as incurred rather than tested against the fee schedule, and treasury cannot show which services the company pays for or at what rate.

EDI 822 Analysis Code Ingestion & Automated Bank Fee Audit Daemon
EDI 822 account analysis ingestion that parses every service line and volume by account, with an audit daemon that compares billed rates to the negotiated schedule and flags increases and unused services.
Continuous Assertion Rule
Fee assertion: each billed service line must match a negotiated rate for that service and account, and a line with no schedule match or a higher rate is flagged before the fee expense posts.
