A suite of purpose-built add-ons that bring full e-invoicing compliance to GravityForms: VAT validation, IBAN checks, EN 16931-compliant tax fields, ZUGFeRD output, and more.
e-Invoice Viewer
Render structured e-invoices directly inside WordPress — no external viewer needed. Supports all major formats as XRechnung, ZUGFeRD and PEPPOL BIS Billing 3.
VAT-ID Field
Adds a smart VAT-ID field that validates the number in real time against the EU’s VIES system — no manual lookup required.
IBAN & BIC Fields
Drop-in IBAN and BIC fields with format validation and live bank account verification before submission.
EN 16931 Tax Fields
Replaces generic tax inputs with EN 16931-compliant tax fields — the correct codes, structures, and values the standard requires.
Code Table Fields
Field types with built-in lookup and validation against UNTDID, ICD, and VATEX code tables — always in sync with the official lists.
ZUGFeRD Generator
Generates fully compliant ZUGFeRD 2.x e-invoices from GravityForms submissions — PDF/A-3 with embedded XML, ready for submission.
EasyBill Integration
Connects GravityForms directly to EasyBill — sync contacts, create invoices, and push billing data without leaving WordPress.
