Is there a perfect invoice format?
There is no direct invoice layout, but certain keywords and unique designations improve the recognition rate.
How can I improve recognition?
In addition, it is easier for OCR recognition if all keywords (e.g., invoice no.) are in German. There is no list of keywords, as it depends on several factors in which value is finally extracted.
In principle, however, the clearer the designation, the easier the extraction. The gross amount, for example, is clearer than the final total. However, if the word gross amount appears several times on an invoice (e.g., in the course of individual items) and only the keyword final total appears on another invoice, then the final total is again clearer.
Recognition cannot be actively improved even for individual invoices. However, this is gradually improved over time, so that a better readout does not occur after a certain period, but simply over a longer period in general.
Do you receive more than 100 invoices per month from one supplier and want them to be recognized immediately and accurately? In this case, we can create an individual "template" for you and "train" the system on this one supplier. However, this is only possible if the invoices are received and processed digitally (no scanning).
