With a revenue of more than €15 billion, STRABAG is one of Europe's leading technology groups for construction services. The company's portfolio includes all areas of the construction industry and covers the entire construction value chain.
STRABAG had to create the conditions to offer not only a predominantly paper-based exchange of invoices with business partners, but also the email transmission of invoice documents and electronic exchange of invoice data in a structured and standardized manner in the European Group countries. One particular challenge is to implement the respective national regulations on invoice exchange in the individual Group countries in accordance with the law.
Moreover, it was necessary to take into account the fact that the changeover to invoice transmission to public-sector customers in a data record format that conforms to the EU standard, as required at B2G1 level in the EU, had to be solved optimally - extended by country-specific requirements of the individual EU Member States.
1 B2B means business-to-business, and B2G means business-to-government.
STRABAG has implemented Comarch EDI and Comarch E-Invoicing for the electronic exchange of invoices. Comarch guarantees compliance with all legal requirements in 17 EU countries at B2B and B2G levels.
The focus was on the exchange of electronic invoices, including the establishment of the associated technical infrastructure and organization. In order to quickly increase the volume of digital invoices, the first step was to implement PDF invoices via email.
Furthermore, the focus is permanently on B2G invoices, as there are legal requirements that must be complied with. After consulting with STRABAG on specific countries, Comarch takes care of the timely integration and implementation of country-specific formats and transmission channels.
As a further step in the project, B2B invoices are also to be implemented as a structured data record (EDI or XML). This functionality will be pushed until the end of 2021, the clear goal being to integrate only business partners with large invoice volumes (number of invoices).
Communication between Comarch and STRABAG takes place via an SFTP server provided by STRABAG. The exchange of invoice data with the STRABAG ERP system is handled via a standard in-house interface. Thus, there is a central interface that can transfer all invoice data from a wide variety of formats.
Due to the heterogeneous business partner structure at STRABAG, a simple variant of "onboarding" was chosen. If the conditions according to STRABAG's e-invoicing website are met, the PDF process is available to every B2B business partner without any additional agreement.
Using Comarch's self-onboarding platform, B2B business partners can integrate into the e-invoicing process should they wish to exchange a structured data set (EDI or XML). It is then possible to exchange electronic invoices quickly and smoothly via secured communication channels. This integration should be convenient and resource-saving for business partners and STRABAG.
