PEPPOL facilitates the pre-award and post-award procurement process with standardised components by focussing on the most complex eProcurement elements (marked yellow in the graphic below):

• validation of eSignatures based on electronic certificates issued by authorities
• a Virtual Company Dossier to submit standardised company information (evidence, certificates and attestations)
• an eCatalogue to submit offers about goods and services in a standardised format

• the eCatalogue to exchange information about goods and services offered under the contract
• eOrdering and eInvoicing providing the buyer and suppliers with defined procedures to share common business information
• the Transport Infrastructure, the foundation of all PEPPOL post-award services, based on common, national IT compatible standards and interconnecting eProcurement communities
