How does the "Tax ID" parser work?
Our "Tax ID" parsing rule preset lets you create a parsing rule capable of detecting and extracting European, US, Australian, & Canadian tax numbers from Invoices and Purchase Orders with only two clicks. This will allow to easily extract European VAT, US Employee ID, Australian and Canadian Business Numbers from PDF Invoices.
Under the hood, predefined patterns are 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 tax IDs from a variety of different purchase & sales order layouts.
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 Tax-IDs are not recognised?
Most of the time this means that we do not know the format of the Tax ID to parse yet. We can however add new patterns 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.
