UC62: Bank Reconciliation Automation

The Problem

Daily/monthly bank-to-book reconciliation across dozens of accounts is arguably the most repetitive, rule-based task in finance. Reconciliations consume 20 to 40 hours monthly across treasury and accounting teams. Timing differences (deposits in transit, outstanding checks) accumulate, requiring subjective categorization. Reconciling items age uncorrected, blocking month-end close. Errors (amount transposition, duplicate deposits) propagate into GL.

What the Agent Does

Ingests bank statements daily (BAI2 format, MT940, CAMT.053, or CSV files)
Ingests GL cash account detail (posting date, amount, reference, description)
Performs automated three-way match between bank statement, GL, and outstanding items register:
Auto-matches transactions by amount and date (±3 days tolerance)
Fuzzy-matches on reference number and description
Identifies timing differences (deposits in transit, outstanding checks, in-process wires)
For unmatched items, categorizes reconciling item type:
Deposit in Transit: GL deposit before bank posting (timing)
Outstanding Check: Check cleared GL but not yet cleared bank (timing)
Pending Wire: Wire initiated GL but not yet cleared bank (timing)
Bank Charge: Bank deduction not yet recorded GL (missing entry)
Deposit Variance: Amount mismatch (error investigation required)
For categorized reconciling items, suggests adjusting entries or follow-up actions
Auto-posts routine adjustments: bank charges, timing entries (with approval workflow)
Generates reconciliation summary: matched items, reconciling items categorized, aged reconciling items, resulting GL variance
Flags aged reconciling items (>20 days) for escalation to treasury/accounting

Data Requirements

Data Sources:

Bank statements , BAI2 files, MT940, CAMT.053, or CSV export with transaction detail, balances, fees
ERP GL module , Cash account transactions (posting date, amount, reference, description)
Outstanding check register / cleared check list , Check numbers, amounts, issue dates, clearing dates (historical)
Bank portal , Account balances, fee schedules, wire activity logs

Data Classification:

Public: None
Internal Structured: Bank statements, GL transactions, outstanding item registers
Internal Unstructured: None
External Third-Party: Bank statement feeds
Sensitive/Regulated: Cash account balances and transactions (balance sheet item)

Data Quality Requirements:

Timeliness: Daily (bank statement should be available same-day or next-day)
Completeness: 100% of bank transactions and GL transactions must be available for matching
Accuracy: Bank statement amounts and GL posting amounts must be accurate; outstanding check register must be current

Integration Complexity: Medium , Requires bank statement feed integration (BAI2/MT940/CSV parser), GL transaction sync, and matching/reconciliation logic

Why It Scores Well

Time savings are massive and immediate: 70 to 80% reduction in manual reconciliation effort. Error reduction is significant (fewer transposition errors, fewer missed bank charges). Month-end close is accelerated when reconciliation is automated and anomalies flagged early. Audit trail is comprehensive: every match decision, every categorization, every adjustment is logged.

Regulatory Alignment

SOX 404: Cash reconciliation is a key control for preventing and detecting errors
GAAP: Cash balance on GL must agree with bank statements monthly
COSO: Reconciliation is integral to preventing unauthorized cash transactions
