The switch to electronic invoices such as ZUGFeRD and XRechnung optimizes the invoicing process, saves time and reduces costs. But in order for the digital documents to be processed correctly by the recipient systems, they must meet a certain standard.
This is where validation comes into play. A validation checks whether your e-invoice is formally correct and compliant with the respective specification (e.g. EN 16931). Successful verification is key to avoiding rejections by the recipient and associated payment delays.
