Search for the cost of manual order entry and you will find confident figures — a few dollars an order, a percentage error rate, a share of a CSR's day. Follow the citations and most lead to another vendor page quoting a third. We are not going to add to that pile.
What follows is the arithmetic to produce your own number. It takes about ten minutes and every input is something you already know or can measure this week. Your number is more persuasive internally than anyone's benchmark, because nobody can argue with it.
The four inputs
| Input | How to get it | Typical source |
|---|---|---|
| Emailed orders per day | Count one normal week and divide by five. Not a peak week and not a quiet one. | The shared inbox |
| Minutes per order, end to end | Time ten real orders from opening the email to the order being saved. Include the interruptions — they are part of the job. | A stopwatch and one afternoon |
| Loaded hourly cost of the people doing it | Salary plus employer taxes and benefits, divided by worked hours. Not the base rate. | Payroll |
| Rework rate | Of last month's orders, how many needed a correction, a credit, a re-ship or an apology call? | Credit memos and your own memory |
The direct cost
Orders per day × minutes per order ÷ 60 × loaded hourly cost × working days per year. That is the labour going into keying, and it is the number people usually stop at.
Work it through once. Forty emailed orders a day at nine minutes each is six hours of desk time daily — most of one full-time person, before anything goes wrong.
The cost that is larger and less visible
Rework is where the real money is, and it is systematically underestimated because its cost is spread across departments that never total it.
A single mis-keyed line does not cost nine minutes. It costs the picking time, the freight out, the freight back, the restocking, the credit note, the call, and a variable amount of goodwill with a customer who now checks their next three orders carefully. Multiply your rework count by an honest all-in figure per incident rather than by the order-entry time.
The question that produces the real number
Ask the person who fixes the mistakes, not the person who makes them. They know exactly how long a wrong shipment takes to unwind, and they have never been asked to add it up.
The cost nobody puts in the spreadsheet
Order entry scales with sales rather than with headcount. That is the wrong direction: a good quarter creates a worse desk, and the constraint on taking more business becomes how fast two people can type.
It also concentrates on specific individuals. When the person who knows what a particular customer's shorthand means is on holiday, the orders still arrive and the knowledge does not. That is a real operational risk that does not appear on any cost line.
What to do with the number
- If the direct cost alone is under a few thousand dollars a year, automation is not your problem and no honest vendor should tell you otherwise.
- If rework is the larger half, the thing to buy is accuracy and blocking, not speed.
- If the constraint is that growth requires hiring, that is the argument to make internally — it is about capacity, not cost saving, and it survives scrutiny better.
We would rather you ran this before talking to us. If the arithmetic says no, it says no, and finding that out from a spreadsheet is cheaper than finding it out from a pilot.
