# What is an electronic invoice (e-invoice)?
An electronic invoice (e-invoice) is a digital invoice created, sent, received, and processed in a structured electronic format without paper. Unlike PDF invoices, e-invoices use standardized formats (like XML, EDI, UBL, or PEPPOL) that enable direct system-to-system data exchange between buyer and seller accounting systems. E-invoicing eliminates manual data entry, reduces processing costs by 60-80%, speeds up payment cycles, reduces errors to near zero, and provides real-time visibility. Many countries mandate e-invoicing for tax compliance. E-invoicing is becoming the global standard for B2B transactions, with the EU and many other regions requiring adoption.
