How to keep an audit trail when converting statements (source PDFs + balance checks)

Maintaining an audit trail when converting statements protects you and your clients during reviews. Here's how to document your process properly.

What to preserve

• Original PDFs: Keep source statements in a secure, organized folder structure
• Conversion logs: Document when each statement was converted and by whom
• Balance validations: Record opening/closing balance checks and any discrepancies found
• Adjustments: Document any manual corrections made during reconciliation

File organization

1. Create a folder structure: ClientName/YYYY/MM/Statements/ and ClientName/YYYY/MM/Reconciliations/
2. Name files consistently: Original_ClientName_Account_YYYY-MM.pdf and Reconciled_ClientName_Account_YYYY-MM.xlsx
3. Include a reconciliation summary sheet that links to source PDFs and documents any issues.
4. Add metadata: conversion date, tool used, validator name, approval status.

Documentation checklist

• Record any transactions that couldn't be automatically matched and why.
• Note any balance discrepancies and how they were resolved.
• Document client communications about missing transactions or statement issues.
• Keep a log of conversion errors or data quality issues for process improvement.
