How does the Purchase Order Number parser work?

Our "Purchase Order Number" parsing rule preset lets you create a parsing rule capable of detecting and extracting PO Numbers with only two clicks. Under the hood, a combination of pattern and keyword based recognition is used and you should be able to get reliable results without the need of tweaking the parsing rule options.

This intelligent filter does not rely on the position of your data inside the document. This means that the same parsing rule can be used to extract PO Numbers from a variety of different purchase & sales order layouts. 

How exactly does the parsing work?

Our PO Number extraction filter uses a combination of pattern and keyword based recognition. Basically we first extract anything which looks like an PO number and we then look for certain keywords nearby. Docparser comes with a ready-to-use keyword dictionary which aims to cover most PO layouts out of the box.

What can I do if my PO Numbers are not recognised?

Most of the time this means that our keyword dictionary is missing a certain keyword used in your purchase order template. We can alter our dictionaries easily and will be happy to resolve the problem for you. Please refer to this article on how to report issues with Invoice, Sales and Purchase Order parsing presets.
