Reception & Validation
of XML E-Invoices via various channels (e-mail, web services, Peppol, EDI)
An E-Invoice is an electronic invoice that is treated like a paper invoice in the accounting system. It is mandatory in many countries worldwide for all goods and services transactions with government authorities. In Germany, these electronic invoices are sent to the federal government in XRechnung format.
Countries are now gradually obliging companies to use e-Invoices not only for the federal government, but for all B2B business transactions (see Germany below). This form of invoice creation and data transfer is therefore particularly important and a must for SAP system users when it comes to process automation.
EPO Consulting is one of the leading companies in the field of electronic invoicing worldwide. Thanks to years of experience and countless implemented projects, we can offer the right solution for every company, both for incoming and outgoing invoices!

Features at a glance
E-Invoice Viewer
Our EPO E-Invoice viewer can convert XML e-Invoices including embedded attachments into a readable HTML file within seconds, making processing much easier.
E-Invoice Validator
With our validator, you can check and validate the correctness of your created and received E-Invoices. This prevents potential errors and saves costs.
EPO e-invoicing for SAP as a global solution
We offer a simple solution for your SAP system and for all your users. Our EPO E-Invoice software is integrated into your existing SAP system using a print programme. This automatically generates an E-Invoice in the XML or PDF format requested by the customer and displays it in the SAP GUI. With a simple push of a button, this E-Invoice can be securely sent to the recipient in a fraction of a second. This saves time and costs.
You can use our solution for all your customers worldwide and send them the desired E-Invoice format directly via email, web service or PEPPOL. This way, the whole thing is rounded off and enables you to better monitor and control your incoming and outgoing payments.
We also offer E-Invoice solutions for countries such as Germany (XRechnung), Italy (FatturaPA) and Austria (ebInterface) that have been developed down to the last detail. The basic XML format is always UBL XML, which is converted into the respective target format.
E-invoicing mandatory in Germany from 2025
The German Federal Council’s approval of the Growth Opportunities Act (WCG) on 22 March 2024 paved the way for mandatory E-Invoicing in Germany. For companies, this means the following:
-
From 1 January 2025, companies based in Germany must be able to accept electronic invoices in accordance with EN16931. E-Invoices in accordance with the EN16931 standard must have a structured electronic format, be created and transmitted electronically and be able to be processed electronically. These requirements are met by the 2 purely electronic XML formats UBL XML and CII XML in accordance with EN16931.
-
The recipient’s consent to receive EN16931-compliant E-Invoices is no longer required. On the contrary: the invoice recipient must explicitly agree to the deviation from the E-Invoice obligation for “other” electronic formats (e.g. PDF).
-
-
From 1 January 2027, only e-invoices may be sent in B2B business transactions within Germany.
-
For companies with an annual turnover of less than 800,000 euros per year, this regulation will apply from 1 January 2028.
-
If you conduct B2B business in Germany and use SAP in your company, you must therefore integrate a system that enables you to receive E-Invoices within the next few months. By 2027, or 2028 at the latest, you must also be able to create and send E-Invoices from SAP.
Our EPO E-Invoice for SAP software enables you to do just that and combines additional features such as visualisation and validation in one product. So don’t hesitate and make an appointment today for a non-binding initial consultation.
If you are currently in the conversion phase from SAP R/3 ECC to S/4HANA, we can integrate the solution in parallel. Your invoice processing will continue to function smoothly until the changeover is complete.
