Outgoing invoices - 100% electronic and paperless!

The usage of the outgoing electronic invoice process (“e-invoicing”) leads to significant rationalisation potential in the accounts receivable department and is rightly at the top of the list of IT-oriented projects in many companies. Process costs of 4 to 6 Euros per classic paper invoice can be very quickly reduced to only a few cents by interposing the e-center.

The outgoing electronic invoice process completely eliminates the necessity of sending paper documents. e-integration offers the respectively optimal method for your situation in regard to concept, implementation and operation. You simply connect your ERP or financial accounting system with our e-center via one single interface and your invoice data is processed there as follows:

  • In the case of customers, who are not EDI compatible, - typically SME -, your invoices are converted into a PDF documents and sent as an attachment in an E-mail.
