KhaqanWhat is document OCR into an ERP?
Document OCR into an ERP is the pipeline that turns scanned or emailed documents, most often supplier bills, into structured ERP records: extract the text with optical character recognition, interpret the fields, match them to existing data and queue the result for human approval.
The classic version used OCR alone, with a template per supplier that mapped fixed positions on the page to fields, and it broke whenever a supplier changed its layout. The current version pairs OCR (or a PDF's own text layer) with a large language model that reads the extracted text and returns the fields as structured data: supplier, bill number, date, currency, line items, tax and total. The ERP side then matches the supplier to a partner record, the lines to a purchase order where one exists, and the totals to each other, before creating a draft bill.
It matters because supplier bills are high-volume, repetitive and consequential. Keying them by hand is slow and produces errors that surface at payment time or at audit; automating them badly produces the same errors faster. The design goal is not zero human time but human time spent only on the exceptions.
An example pipeline: bills arrive in a mailbox; a job fetches the attachments, runs extraction, validates the arithmetic (do the lines sum to the total, does the tax match the rate), checks the supplier against the ERP, and creates a draft with a confidence score. Anything below the threshold, or any bill with no matching purchase order, goes to a review queue where a person confirms or corrects it on a single screen. Corrections are logged, because they show which suppliers and which fields fail most.
The common mistake is to post bills automatically because the extraction looked accurate in testing. Handwritten notes, credit notes that look like invoices, duplicate submissions and a supplier's new bank details are exactly the cases a model gets confidently wrong. In practice every bill from an automated pipeline I run passes a person before it is posted.
