Tips
- Keep a running list of disputes until credits show up.
- Paste totals and categories, not raw bank exports with account numbers.
- The AI drafts and organizes. Your accountant or CPA signs off on anything tax-related.
- Review every draft before you send it. You’re accountable for what goes out.
