How the e-arve validator works

1

Upload your e-arve XML

Drag and drop the XML file. The root element must be <E_Invoice> with no XML namespace — the standard Eesti Pangaliit structure. The validator auto-detects e-arve and routes to the dedicated Estonian validator.

2

Schema validation + business rules

The validator reads the schema version from <Header><Version> and applies the matching XSD (1.11 or 1.2). Then it runs the EA-R001…R008 business rules covering registry codes, IBAN MOD-97 checksum, VAT consistency and amount totals.

3

Read the report

Schema errors come back with XSD line/column references; business-rule violations are reported with the Estonian rule code (EA-R001 through EA-R008) and a plain-English description.

What the e-arve validator checks

XSD schema (1.11 + 1.2)

Per-document version detection. If the file declares <Version>1.11</Version> the 1.11 XSD is used; if it declares 1.2 the newer EN 16931-aligned 1.2 schema is used. Structural errors fire with line and column numbers.

Estonian business rules (EA-R001–R008)

Invoice number presence (R001), invoice date validity (R002), Estonian 8-digit registry codes for seller and buyer (R003, R004), total amount consistency with line items (R005), VAT calculation correctness (R006), payment due date logic (R007) and IBAN MOD-97 checksum verification (R008).

Automatic format detection

The validator auto-detects e-arve from the <E_Invoice> root element. PEPPOL invoices and XRechnung invoices use different XML structures and get routed elsewhere — you never have to pick a format manually.

IBAN MOD-97 verification

Any IBAN value in PaymentInfo/PayToAccount or AccountInfo/IBAN is validated using the ISO 13616 MOD-97 checksum algorithm. Catches typo'd account numbers before the invoice goes out via banking channels.

Why a separate Estonian e-arve validator?

E-arve is the Estonian banking-channel e-invoice format published by Eesti Pangaliit (Estonian Banking Association). It predates PEPPOL adoption in Estonia and remains the dominant format for domestic B2B and B2G invoices exchanged via banking infrastructure (LHV, SEB, Swedbank) and Estonian e-invoice operators (Finbite, Omniva, Telema). The XML structure has nothing in common with PEPPOL UBL or EN 16931 CII — a different root element, different field names, no XML namespace at all. Generic PEPPOL or XRechnung validators reject e-arve documents as "invalid XML" because they don't recognise the structure.

The aiDoks validator handles e-arve as a first-class format alongside PEPPOL, XRechnung and Factur-X. Upload your e-arve XML, get the full validation report with both XSD schema errors and Estonian business-rule violations, and fix issues before submitting through your bank's e-arve channel.

Common e-arve validation errors

  • EA-R001 — Invoice number is missing or empty. The InvoiceNumber element under InvoiceInformation must be populated.
  • EA-R003 — Seller registry code is not 8 digits. Estonian company codes are always 8 digits — most often the issue is a leading-zero stripped by Excel during data entry.
  • EA-R005 — Total amount mismatch. The TotalSum in InvoiceSumGroup must equal the sum of line items within ±0.01 tolerance.
  • EA-R006 — VAT calculation inconsistent. VATSum must equal SumBeforeVAT × VATRate / 100 within ±0.01 tolerance.
  • EA-R008 — IBAN fails MOD-97 check. Usually a typo — the IBAN is structurally well-formed but the check digits don't match the rearranged account number. Banks will reject the payment outright.

For Estonian companies dealing with cross-border invoices

Many Estonian companies receive both domestic e-arve from local suppliers via banking channels AND PEPPOL invoices from cross-border EU suppliers via PEPPOL access points. Rather than running two validators, the aiDoks tool detects which format you uploaded and applies the matching pipeline. Same UI, same report structure, one less tool to maintain.

Estonian e-arve validator: FAQ

¿Qué es el formato e-arve estonio?

E-arve es el formato nacional estonio de factura electrónica publicado por Eesti Pangaliit (Asociación de Bancos de Estonia). Es distinto de PEPPOL — anterior a la adopción de PEPPOL en Estonia y sigue siendo el formato dominante para facturas B2B y B2G nacionales intercambiadas a través de canales bancarios (LHV, SEB, Swedbank) y operadores (Finbite, Omniva, Telema). El validador admite las versiones de esquema 1.11 y 1.2.

¿Por qué necesito un validador separado para el e-arve estonio?

E-arve utiliza una estructura XML completamente diferente a PEPPOL UBL o CII: el elemento raíz es <E_Invoice> sin espacio de nombres XML, y el diseño del documento sigue las convenciones bancarias estonias en lugar del modelo EU EN 16931. Los validadores PEPPOL o XRechnung no lo reconocen. El validador aiDoks detecta la raíz e-arve automáticamente.

¿Qué comprueba el validador e-arve?

Dos niveles: validación del esquema XSD (contra el esquema oficial e-arve, 1.11 o 1.2 según la versión declarada en la Cabecera del documento) más reglas de negocio implementadas en Java: presencia del número de factura (EA-R001), validez de fecha (EA-R002), códigos de registro estonios de 8 dígitos (EA-R003, EA-R004), coherencia de sumas (EA-R005), corrección del cálculo del IVA (EA-R006), lógica de la fecha de vencimiento (EA-R007) y suma de comprobación IBAN MOD-97 (EA-R008).

¿El validador admite tanto e-arve 1.11 como 1.2?

Sí. Cada documento subido declara su propia versión de esquema en <Header><Version>; el validador lo lee y aplica el XSD correspondiente. 1.11 sigue siendo la versión dominante en el tráfico bancario estonio; 1.2 es la variante más nueva alineada con EN 16931.

¿El validador e-arve estonio es gratuito?

Sí, gratuito y sin cuenta. Suba su XML e-arve y obtenga validación instantánea con errores de esquema y violaciones de reglas de negocio específicas de Estonia marcadas con códigos (EA-R001 a EA-R008).

¿Puedo validar también facturas estonias en formato PEPPOL o EN 16931?

Sí — el mismo validador aiDoks admite PEPPOL BIS 3.0, XRechnung, EN 16931 y Factur-X / ZUGFeRD además de e-arve estonio. Un solo validador cubre ambos mundos.
