Core principles
Lead with statement period
Start filenames with YYYY-MM to enable chronological sorting. This ensures statements appear in order when sorted alphabetically in any file system.
Include account identifier
Add last 4 digits of account number to distinguish between multiple Chase accounts. Never include full account numbers for security.
Add bank name for multi-bank environments
Include "Chase" in filename when managing statements from multiple banks. This enables quick filtering and prevents confusion during reconciliation.
Use consistent separators
Use underscores or hyphens consistently throughout filenames. Avoid spaces and special characters that cause issues across platforms.
Consider client codes for bookkeeping firms
Add client identifiers when managing multiple client accounts. This enables automated filing and quick visual identification.
Common mistakes
Using download date instead of statement period
Why it's wrong: Download date (when you saved the file) differs from statement period (what the statement covers). This breaks chronological organization and causes confusion during period-end reconciliation.
Fix: Always use the statement period date (e.g., 2025-10 for October 2025 statement) regardless of when you downloaded the file. Extract this from the statement header.
Including full account numbers in filenames
Why it's wrong: Full account numbers in filenames create security risks if files are shared, backed up to cloud storage, or accessed by unauthorized users.
Fix: Use only the last 4 digits of the account number. This provides enough information for identification while maintaining security.
Omitting bank identifier in multi-bank environments
Why it's wrong: Without bank name, you cannot distinguish Chase statements from Bank of America, Wells Fargo, or other banks when managing multiple accounts.
Fix: Include "Chase" in every filename, especially if you manage accounts from multiple banks. This enables quick filtering and prevents mix-ups.
Using spaces instead of underscores or hyphens
Why it's wrong: Spaces in filenames cause issues with command-line tools, scripts, and some accounting software. They require escaping and can break automated workflows.
Fix: Replace all spaces with underscores (_) or hyphens (-). Use one separator consistently throughout your naming convention.
Frequently asked questions
How do I handle multiple Chase accounts?
Use the last 4 digits of each account number in filenames (e.g., 2025-10_Chase_4567.pdf and 2025-10_Chase_8901.pdf). For additional clarity, add account type (Checking, Savings, Business) before the account number.
Should I include the full date range in the filename?
Optional. Leading with YYYY-MM is sufficient for most use cases. Add full date range (e.g., Sep15-Oct14) only if you need to distinguish between mid-month statement periods or have non-standard billing cycles.
Can I automate this for statements downloaded from Chase online banking?
Yes. Connect your download folder to renamed.to and we automatically extract account numbers, statement periods, and dates from Chase PDF statements. The AI handles both personal and business account formats.
What about Chase credit card statements?
Use the same pattern but add "CreditCard" or "CC" to distinguish from checking/savings (e.g., 2025-10_Chase_CC_4567.pdf). This prevents confusion when reconciling different account types.
How do bookkeeping firms handle client Chase statements?
Add client code after bank identifier: YYYY-MM_Chase_ClientCode_Last4.pdf (e.g., 2025-10_Chase_ACME_4567.pdf). This enables automated filing into client folders and quick visual identification.
