Email Trails and Record Retention: Why I Write Everything Down
Evidence-based finance work: how I preserve approvals and defend decisions later.
I don't keep records for auditors—I keep them for future me
The question is not "Will someone ask?" It's "What happens when they ask?" I've been in situations where a decision made in 15 minutes needed an explanation a year later. Proper documentation protects both the company and the individual making financial decisions, providing a clear audit trail that demonstrates due diligence and compliance with policies.
What I retain as a minimum
- Approval artifacts for invoices, refunds, and credits
- Contract versions that explain pricing and obligations
- Reconciliation workpapers for key balance sheet accounts
- Change logs for rate tables, GL mappings, and policies
Comprehensive documentation framework
I maintain a systematic approach to documentation across all finance functions:
Transaction documentation:
- Source documents for all transactions
- Approval chains with timestamps
- Supporting analysis and calculations
- Exception documentation and explanations
Communication records:
- Email threads related to financial decisions
- Meeting minutes with action items
- Phone call summaries with participants
- Instant messages related to approvals
Policy and procedure documentation:
- Internal policy changes and updates
- Training materials and certification records
- Process documentation and updates
- Compliance checklists and results
Legal risk is often a documentation problem
If an action is challenged, the record is the evidence. I keep clean files and consistent naming like:
- `close/2025-11/bank-recon.pdf`
- `ap/vendor-onboarding/acme-w9.pdf`
Electronic document management systems
I utilize technology to enhance document retention:
File organization:
- Consistent folder structures across all systems
- Clear naming conventions with dates and descriptions
- Version control for multiple iterations of documents
- Access controls to protect sensitive information
Search and retrieval:
- Metadata tagging for easy searchability
- Cross-referencing between related documents
- Indexing systems for quick access
- Backup systems to prevent data loss
Email retention policies and best practices
Email is a critical component of documentation:
Email filing system:
- Categorized folders by function and date
- Regular archiving of older emails
- Clear subject lines that describe content
- Regular cleanup of unnecessary emails
Email content guidelines:
- Include all relevant details in email bodies
- Reference supporting documents clearly

Quality control for documentation
I implement checks to ensure documentation quality:
Completeness reviews:
- Verify all required fields are filled
- Ensure supporting documents are attached
- Check that approval chains are complete
- Confirm all relevant details are included
Accuracy verification:
- Cross-reference with source systems
- Validate calculations and amounts
- Confirm dates and deadlines
- Ensure proper authorization levels
Digital preservation strategies
To maintain long-term access to records:
- Regular format migration to current standards
- Multiple backup locations for redundancy
- Regular testing of retrieval processes
- Documentation of file system changes
Audit preparation through documentation
Good documentation streamlines audit processes:
Preparation activities:

- Board meeting minutes and resolutions
Regulatory compliance in documentation
I ensure documentation meets regulatory requirements:
- SEC filing requirements for public companies
- SOX compliance for internal controls
- Tax documentation requirements
- Industry-specific regulations
Technology tools for documentation
I leverage various tools to enhance documentation:
Document management systems:
- Centralized storage with access controls
- Version control and change tracking
- Search and retrieval capabilities
- Integration with other business systems
Collaboration tools:
- Shared drives with proper permissions
- Cloud storage with security features
- Workflow tools for approval processes

Training and awareness
I ensure proper documentation practices throughout the team:
Training programs:

My rule
If it affects cash, revenue, taxes, or contracts, it deserves a paper trail. This principle guides my approach to documentation and ensures that all significant financial activities are properly recorded and supported.
