Backup: Weekly export from Wave to encrypted Google Drive folder.
Human Oversight: AI suggests, you approve. Never give AI sole authority to move money.
FAQ: Your AI Finance Automation Questions
Q1: Is Wave really free forever? What's the catch?
A: Yes, accounting, invoicing, and receipt scanning are 100% free. They make money on payment processing (if you use their payments) and payroll services. For businesses processing under $50K/year, you can stay completely free.
Q2: I already use QuickBooks/Xero. Should I switch?
A: Not necessarily. Apply the same principles: Use your software's automation features, export data monthly to Google Sheets for AI analysis, and use ChatGPT for insights. The philosophy matters more than the specific tool.
Q3: How accurate is AI receipt scanning?
A: 2025 models achieve 95%+ accuracy on clear receipts. Always review for the first month, but after that, you'll mainly just confirm. The key: take clear photos in good light.
Q4: What about businesses with complex inventory or manufacturing?
A: Start with the cash flow and expense tracking automation. For inventory, consider free tools like Odoo (open-source) or paid upgrades when needed. The AI analysis layer (Google Sheets + ChatGPT) works regardless of complexity.
Q5: Can this handle multiple currencies?
A: Wave supports multiple currencies in paid tiers ($35/month). For free tier: Use Wise or Revolut for conversions, then record in your primary currency.
Q6: I'm not comfortable connecting my bank to any app. Alternatives?
A: Manual weekly CSV export from your bank → Import to Wave or Google Sheets. You'll still get AI categorization and analysis, just with more manual uploading.
Q7: How do I ensure this is tax-compliant?
A:
Choose AI tools that generate audit trails (Wave does)
Always have a human (you or your accountant) review quarterly
Keep digital copies of all receipts (Wave does this automatically)
Use AI for organization, not for tax advice
Q8: What happens if an AI tool mis-categorizes something?
A: You correct it once. The AI learns. Over 3 months, error rates typically drop below 5%. Always run a "Review Unusual Transactions" report before month-end closing.
Q9: Can I give my accountant access to this system?
A: Yes! Wave allows free accountant access. They get their own login with appropriate permissions. This actually saves them time (and saves you money on bookkeeping fees).
Q10: What's the biggest risk with AI finance automation?
A: Complacency. The system is designed to alert you to anomalies, but you must review key reports monthly. Think of AI as your super-efficient junior bookkeeper, not a replacement for your oversight.
