• Error Correction: $50-100 per error (duplicate payments, late fees)
• Storage & Archiving: $2-5 per invoice annually
• Opportunity Cost: Time not spent on strategic analysis

Calculate Your ROI

Use this framework to estimate your savings:

1. Count your monthly invoice volume
2. Calculate current processing cost (labor hours × hourly rate)
3. Estimate error correction costs (errors × resolution cost)
4. Project automation savings (typically 80-95% reduction)
5. Subtract automation costs (software + implementation)

Most businesses achieve positive ROI within 3-6 months, with ongoing savings compounding over time. The question isn't whether to automate—it's how quickly you can implement it.
