Would you say that you are familiar with eInvoicing in general (what is eInvoicing, what is an electronic invoice)?
Are you familiar with the requirements of EU Directive 2014/55/EU on the adoption of eInvoicing by Public entities throughout the European Union?
Are you aware of the upcoming eInvoicing European Standard, which is being developed by CEN, and its requirement for all Public Entities in the EU to comply with it?
Are your current invoicing, accounts payable management, and accounting systems (whether in-house or out-sourced) designed to be compliant, or are considered likely to be compliant with the eInvoicing European Standard (i.e. capable of receiving and processing invoice messages conforming with the semantic data model for the core elements of an electronic invoice and capable of receiving messages using the syntaxes that will (or will be likely to) comply with the European standard on electronic invoicing)?
