Features

Data Sources

Storage Architecture

• Location: ~/.billclaw/ (configurable)
• Format: Monthly partitioned JSON files
• Caching: TTL-based in-memory cache
• Deduplication: 24-hour window based on transaction ID
• Streaming: Efficient handling of large datasets

Export Formats

• Beancount: Double-entry accounting format
• Ledger: CLI accounting tool format
• CSV: Spreadsheet-compatible format

Security

• Platform keychain storage for credentials (keytar)
• Audit logging for all credential access
• Optional AES-256-GCM encryption
• Local-first architecture - your data never leaves your control

Configuration

Configuration is stored in ~/.billclaw/config.yaml:

accounts:
  - id: plaid-checking
    type: plaid
    name: "My Checking Account"
    enabled: true
    syncFrequency: daily

  - id: gmail-bills
    type: gmail
    name: "Bill Email Fetcher"
    enabled: true
    syncFrequency: daily

storage:
  path: "~/.billclaw"
  format: json

sync:
  defaultFrequency: daily
  retryOnFailure: true
  maxRetries: 3

Runtime Abstractions

The core package is framework-agnostic and uses runtime abstractions:

• Logger: Abstract logging interface
• ConfigProvider: Configuration management
• EventEmitter: Event system for sync operations

This allows BillClaw to work across different environments (CLI, OpenClaw plugin, future platforms).

Event System

BillClaw emits events for important operations:

• transaction.added - New transactions added
• transaction.updated - Existing transactions updated
• sync.started - Sync operation started
• sync.completed - Sync operation completed
• sync.failed - Sync operation failed
• account.connected - Account successfully connected
• account.disconnected - Account disconnected
• account.error - Account error occurred

Scripts

Troubleshooting

Issue: Plaid Link fails

Solution: Ensure Plaid credentials are configured:

billclaw config plaid --client-id <id> --secret <secret>

Issue: Gmail fetch returns no bills

Solution: Check Gmail filters and sender whitelist:

billclaw config gmail --filters "from:billing@service.com"

Issue: Export format incorrect

Solution: Verify account mappings:

billclaw export --format beancount --show-mappings
