ZUGFeRD is the national platform of associations, ministries and companies to promote electronic invoicing in Germany. The 'e-ZUGFeRD' Invoice' solution of e-integration optimally adapts as a cloud service to the requirements for outgoing and incoming invoices. e-integration provides all ZUGFeRD variations from 'basic' over 'comfort' up to 'extended' including PDF / A-3. So a maximum invoice amount of data can be realized. As a perspective a complete realization or implementation of a fully EDI solution is possible. e-ZUGFeRD is therefore in addition to the classic and proven transmission paths of EDI and portal solutions a new, cross-sectoral way to exchange invoices as easy as paper invoices.
