Accounts payable OCR has been in use long enough that the interesting questions are no longer about whether it works. It works. The questions are how much human review it leaves behind on your particular documents, what it does when unsure, and whether the parts of payables it does not touch are where your time actually goes. All three are answerable in a fortnight with your own invoices.
Judge it on review time, not accuracy
Accuracy figures average easy fields with hard ones and are not comparable between products or between document sets. The number that matters to you is how many minutes per invoice your team still spends after extraction, on your own invoices. Measure that during a trial and the comparison becomes straightforward and specific to you.
Interrogate the uncertain cases
Ask to see what happens when the software is unsure: whether it flags, what the review screen shows, whether the document is visible beside the field, and how quickly a correction can be made. This is the part of the product your team uses most and the part least visible in a sales demonstration, which is a good reason to insist on seeing it.
Check whether capture is your constraint
Time your process end to end before buying. If invoices take minutes to key and days to approve, capture is not the constraint and improving it will not change your elapsed time. This is the single most useful hour anybody can spend before an automation purchase, and it frequently redirects the project.
Questions people ask about accounts payable ocr
Is OCR still the right term?
It is used loosely to cover the whole extraction pipeline, most of which is no longer character recognition in the original sense. The label matters less than what the product returns and how it flags uncertainty.
How long does a fair trial take?
A fortnight of real documents is usually enough to see the review burden clearly, provided you include your difficult suppliers rather than only the easy ones.
What is the most common disappointment?
Expecting it to reduce exception handling, which it does not touch. Exceptions are about documents disagreeing, not about documents being read.
