An electronic invoice, or e-invoice, is an invoice issued, transmitted, and stored in a structured digital format that enables automated processing by business and tax systems. Unlike a scanned image or PDF, a fully structured e-invoice contains machine-readable data fields for supplier, purchaser, line items, quantities, prices, taxes, and totals, allowing automatic validation and posting.

Common formats and standards include XML-based formats such as UBL 2.1 and UN/CEFACT Cross-Industry Invoice; the European EN 16931 semantic data model; mixed formats like Factur-X/ZUGFeRD which embed XML in a PDF document; and country-specific implementations such as Xrechnung in Germany. For cross-border and inter-organizational exchange, networks and profiles like PEPPOL enable standardized e-invoice transmission between buyers and suppliers across jurisdictions.

Legal and regulatory framework: In many jurisdictions, e-invoices have the same legal status as paper invoices if they preserve authenticity, integrity, and readability. The European Union has promoted e-invoicing for public procurement, with directives and related national laws to standardize formats and transmission. Tax authorities often require or encourage e-invoicing and electronic archiving to support VAT reporting and auditability.

Benefits and challenges: The primary benefits include faster processing, reduced manual data entry, improved accuracy and compliance, and easier long-term archiving. Organizations often realize lower administrative costs and faster payments. Challenges can include initial implementation costs, interoperability among systems and formats, data quality issues, and the need for supplier onboarding and ongoing governance.

Adoption and impact: E-invoicing is widely used in government procurement in Europe and is increasingly adopted in business-to-business workflows. Global adoption is growing as standards and networks mature, supporting cross-border commerce and more efficient financial operations.
