List of the Top 7 Billing and Invoicing Software for Peppol in 2026

PEPPOL facilitates the secure exchange of e-invoices and international government documents, providing a seamless connection for ERP systems through a user-friendly RESTful API. Utilizing e-invoicing offers significant cost savings, as sending e-invoices is 59% cheaper and receiving them costs 64% less compared to traditional methods. The inefficiencies of paper invoicing are evident, with e-invoices allowing for quick and economical transfers between bookkeeping systems entirely in the cloud, eliminating the need for physical handling. Additionally, PDF and paper invoices are not permissible for submission to governmental bodies like ministries or public entities, whereas Peppol enables the global transmission of e-invoices in compliance with the new European Directive. If you operate an ERP system or accounting software, integrating with our straightforward RESTful API empowers your customers to send and receive e-invoices directly through their existing applications, while also connecting them to the Peppol network for governmental transactions, enhancing both efficiency and compliance. This integration not only streamlines operations but also supports a more sustainable invoicing process.
