Customization of the OCR API

In certain cases our standard solutions might not be exactly what you are looking for. Luckily we can build custom OCR integrations via our API. 

The input is normally a stream of images or PDFs, the output is JSON (or a different format for structured data), including the extracted information per receipt, invoice, contract, passport, sales order, shipping document, packing slip or any other document. 

From these documents we extract information such as the name, address, date, Chamber of Commerce reference, invoice number, bank account number, total amount, VAT, date of birth and place of birth. 

What is the price of a custom OCR API? 

At Klippa we believe in adding value to our clients for a fair price. Our customization process always starts with identifying your needs during a first meeting. Based on your requirements we will prepare an offer. 

The offer normally includes a one-off setup fee (depending on the complexity of the documents that need to be processed) and a yearly license fee of the OCR API.
