Most ops teams underprice this work because the time is spread across many people. A dispatcher keys a rate confirmation. An AP clerk keys an invoice. An account manager keys a submittal into a spreadsheet. None of it looks like a big project, so no one measures it, and the cost hides inside payroll.
The real damage is the error rate. A single transposed total on an invoice can stall a payment for a week. A wrong quantity on a purchase order ships the wrong count. When the same figure is typed by hand three times as it moves between systems, the odds that all three match are worse than they feel.
Slow re-keying also caps throughput. When volume spikes, the only lever a manual process has is more people or more overtime, and both take time you do not have during the spike. Automation changes the math: the pipeline absorbs the surge without a hiring cycle.
