Every vendor here shows a labour saving. Almost none show the error cost, which at real volume is the larger of the two. Here is both, using only numbers we can trace.
Take a wholesaler receiving 100 document orders a month. At about six minutes each that is 600 minutes, ten hours a month transcribing what a customer already wrote down. At about one minute each it is 100 minutes. The recovered time is roughly eight hours and twenty minutes a month, which you multiply by your own loaded hourly cost, the one number here we cannot supply.
Now the line nobody counts. At a 3% manual error rate, three of those hundred orders go out wrong every month. At about $250 each to unwind, averaged across the picking, the freight both ways, the credit note and the apology, that is $750 a month and $9,000 a year, never attributed to order entry. At the measured 0.5% rate, with a human approving every draft, the expectation falls to about one wrong order every two months, roughly $125 a month and $1,500 a year. The difference is about $625 a month, $7,500 a year, on errors alone.
Set that against the price. Growth is $250 a month for up to 100 orders, or $2,400 a year on annual billing, which saves 20 percent. The error saving alone covers it about three times over before a single recovered hour is counted. Hours are the number people quote in meetings. Errors are the number that shows up in the accounts.
Now run it backwards, at ten orders a month. Ten orders at six minutes is one hour a month, and automating one hour a month is not a business case. The error expectation is 3% of 120 orders a year, about four wrong orders, against about one at the assisted rate. A difference of roughly $750 a year: real money, but an expectation rather than a line on a statement. You may go a full year without an expensive mistake, the person keying ten orders knows those accounts well enough that their real rate beats the average, and the recovered hour has nowhere useful to go. Keep keying.
One more traced figure is worth having in view. On one operator handling one high volume customer, eight hours a day of order entry came down to 40 minutes.
