Cost of Vendor Errors
See formulas
Changed/week = items/week × (% changes ÷ 100)
Error $/week = changed/week × avg error value
Error $/month ≈ error/week × 4.3
Manual hours/month = (minutes/invoice × invoices/week × 4.3) ÷ 60
Receiving Time Savings
See formulas
Zaiko hours/month = invoices × minutes_zaiko × 4.3 ÷ 60
Hours saved/month = manual − zaiko
$ value/month = hours_saved × wage (if provided)
Breakeven vs Manual Entry
See formulas
Breakeven in weeks = price ÷ ((hours_saved ÷ 4.3) × wage)
Disclaimer: These are estimates. Real outcomes vary by distributor, invoice volume, and workflow. You can change the 4.3 factor in the script if you prefer.
