Quick summary

Use multilingual OCR to digitise purchase orders and delivery notes, then compare product codes, quantities and receiving exceptions. This guide gives you a clear, practical explanation before you use the related online tool.

1

Why these documents are difficult

Purchase orders and delivery notes often use supplier-specific layouts, abbreviated descriptions, handwritten receiving notes and mixed product identifiers.

2

Prioritise stable identifiers

After extraction, match barcode, SKU, supplier item code or internal product code before comparing descriptions. Product names can differ while identifiers remain stable.

3

Normalise quantities and units

Convert obvious unit variations such as pcs, pieces and each into a controlled unit dictionary. Do not assume a carton equals a fixed quantity unless pack size is known.

4

Detect receiving exceptions

Compare ordered and delivered quantity to find shortages, over-deliveries, missing items, unexpected items and possible duplicates.

5

Handle uncertain OCR

A low-confidence digit can turn 10 into 70 or alter a product code. Route uncertain lines for manual verification instead of forcing an automatic match.

6

Create the receiving decision

Record accepted quantity, rejected quantity, reason and final decision: accept, partial accept, hold or reject. Preserve the original source for audit.

Frequently asked questions

Can OCR compare a PO and delivery note directly?

OCR extracts text first; a matching engine then normalises and compares line items.

Does row order need to match?

No. Reliable comparison should use identifiers and normalised values, not row position.

Can handwritten notes be recognised?

Printed text is usually more reliable; handwriting quality varies significantly.

What should be manually checked?

Product codes, quantities, units, batch details and receiving decisions.
