The Order Processing Cost Formula
Annual cost = labour + errors + channel overhead, where labour = orders a year x minutes per order / 60 x loaded hourly cost. Errors are orders a year x error rate x cost per error. Channel overhead adds a share of the labour for every order source beyond the first, because each format needs its own reading, logins and follow-up.
Worked example: 30 orders a day
Orders a year = 30 x 260 = 7,800Hours = 7,800 x 10 min / 60 = 1,300 (0.63 full-time staff)Labour = 1,300 x $22 = $28,600Errors = 7,800 x 2% x $50 = $7,800 (placeholder rate and cost: use your own)Channel overhead = (3 - 1) x $28,600 x 15% = $8,580Total = 28,600 + 7,800 + 8,580 = $44,980
Keying 30 orders a day by hand costs about $44,980 a year, or $5.77 an order, with the default error assumptions.
Where the Time Goes
| Step | What happens |
|---|---|
| Read | Open the email or PDF, find the PO number, ship-to and lines |
| Match | Map the customer's item codes and units to yours |
| Key | Type the header and every line into the ERP |
| Check | Compare prices, quantities and dates against the PO |
| Chase | Email or call about anything unclear or missing |
Errors cluster in the match and key steps: a wrong unit of measure or a transposed quantity ships the wrong goods.
