Are you running a webshop with customer requirements for Peppol e-invoices? Often your customers require their Invoices to be sent via the Peppol network using the Peppol formats if they are public and based in Norway or Sweden. This can lead to complications. One of the ways to improve this is to have a run time Peppol lookup on the front of your webshop that helps to ensure that your customer is actually in the Peppol Network when they claim they are (often they are not). A Peppol Lookup service from e-tradesupport is an API allowing you to do these lookups so you can guide your customers correctly in terms of how they should be invoiced making sure that error handling and manual work is minimized.
