The benefits resulting from reducing the time of registration include centralising documentation and easy yet supervised access, as well as relieving the accounting department from mechanical tasks of rewriting data. Instead, the accounting services may use a repository of images and metadata of invoices allowing for the monitoring of timeliness and cost analyses in important advance, i.e. before the invoice is be booked in the financial accounting system.

The registration of an incoming invoice itself can be carried out in the secretarial office immediately after receiving correspondence and described with the invoice data. If the OCR technology is used for this invoice description process, the benefits resulting from the acceleration of registration will be considerable. Moreover, the process of registration of an incoming invoice itself can be part of a general office process of correspondence registration.
