How much time does manual data entry take you? Work it out
Before deciding whether to automate document entry, find out what it costs you today. A simple way to measure it, with your numbers rather than anyone else's.

Software vendors love big numbers: "80% time saved", "hundreds of hours a year". Those numbers were not measured at your desk, so they do not help you decide. What helps is one number of your own: how long typing up documents takes you today, and how much of it you could actually save. Here is how to measure it in a week.
What exactly to measure
Entering a document is not just typing. When you measure, include every step:
- Finding: opening the email, downloading the file, finding the page.
- Typing: copying each value into the system or sheet.
- Checking: going over the amounts and dates again.
- Fixing: dealing with mistakes that surface later, in a reconciliation or a report.
The last step is easy to forget because it happens days or weeks after the typing. One wrong digit in an amount can cost more time than the entire entry did.
One week of measurement
- Pick 20 typical documents from last month, covering every kind you type up.
- Start a stopwatch and enter them as usual, including the checking you normally do.
- For each document, note how long it took, how many values were typed, and whether anything had to be corrected.
- Count how many such documents arrive each month. If you do not know, count last month in your system.
The arithmetic
Documents per month times the average time per document gives the monthly time. Times the cost of an hour of work, it gives the cost.
What automatic reading does not save
Even with automatic reading, someone has to check the result. What changes is the kind of work: instead of typing every value, you go over values that are already filled in and correct the ones marked for review. How much that saves is something to measure, not assume.
Some things do not change at all: deciding which account an expense belongs to, handling exceptions, and the conversation with a supplier about a wrong invoice.
How to compare
Take the same 20 documents and run them through automatic reading. Time it from uploading the file to having checked data in your sheet. In OCR-AI you can do this without paying: 5 free pages every day, so the sample takes a few days. Now you have two real numbers to compare, and the price per page to finish the sum.
When it does not pay
- When there are few documents. Ten documents a month do not justify changing a process.
- When the data is already digital. If the supplier sends the invoice as a data file or straight into your system, there is nothing to read.
- When most documents are handwritten. Checking takes longer there and the saving shrinks. See handwriting and OCR.
