## What is eInvoicing?

The **eInvoicing** app gives Frappe and ERPNext native support for the **PEPPOL BIS Billing 3.0** standard. With it, you can generate, validate, send and receive structured electronic invoices through the PEPPOL network — instead of (or alongside) PDF or paper.

### Key features

- **PEPPOL BIS Billing 3.0**: Full implementation of the specification
- **UBL 2.1 XML**: Compliant generation for invoices and credit notes
- **Multiple document types**: Invoice and CreditNote (CreditNote auto-detected when `is_return = 1`)
- **Validation**: XSD schema + Schematron business rules (BR-CO-15, BR-CO-17, BR-IC-10/11/12, …)
- **HTML preview**: Visual preview of generated XML via XSLT transformations
- **Entity matching**: Incoming XML entities (supplier, items, PO) auto-match to ERPNext master data, with manual fallback
- **Code list management**: Automatic code list handling for PEPPOL standards
- **Profile-based architecture**: Extensible — add country-specific CIUS or other e-document standards via new profiles
- **Service provider integration**: Send and receive via B2B Router or Recommand (see [Service Provider Integration](/docs/edocument/integration/overview))

### Who this is for

- **Administrators** configuring the PEPPOL participant, code lists, and choosing which customers/suppliers exchange documents over PEPPOL
- **Accounting users** sending and receiving invoices day-to-day

### Architecture in one paragraph

The app uses a **profile-based system** so different e-document standards can coexist. Each profile (PEPPOL is the one shipped) defines six function paths: generator, parser, validator, preview, detector, matcher. Outgoing flow: Sales Invoice → generator → UBL XML → validator → attached to EDocument. Incoming flow: XML → detector (profile + company + target type) → validator → matcher (supplier, items, PO) → parser → Purchase Invoice.
