What You Can Do

You can automate your monthly bank reconciliation workflow by uploading bank statements and accounting records side-by-side. Claude matches transactions across accounts, identifies timing differences (deposits in transit, outstanding checks), flags unexplained variances, and generates audit-ready reconciliation documentation. This reduces your monthly closing time from 4-6 hours to 1-2 hours while improving accuracy.

Variance analysis

Flags unmatched transactions and calculates reconciling items (outstanding checks, deposits in transit, bank fees, interest)

Timing difference detection

Distinguishes between legitimate timing gaps and actual discrepancies requiring investigation

Exception reporting

Creates prioritized lists of reconciliation breaks, unexplained items, and amounts requiring follow-up

Audit documentation

Generates reconciliation summaries and supporting schedules formatted for tax preparation and financial review

Multi-account tracking

Handles multiple bank accounts simultaneously while maintaining separate reconciliation workpapers

Error investigation framework

Provides structured questions and validation checks to identify data entry mistakes or fraud indicators

Reconciliation sign-off template

Produces closing statements with account balances, adjustments, and approval signoff for internal controls
