What is Peppol?
Peppol (Pan-European Public Procurement Online) is the global standard for exchanging e-invoices and business documents securely — like SWIFT, but for invoices. InvoStaq connects your business to this network automatically.
How the 4-Corner Model Works
4-Corner Model
Peppol connects senders and receivers through certified Access Points — like postal hubs for digital invoices. InvoStaq acts as your Access Point partner.
BIS 3.0 Standard
Every invoice is automatically converted to Peppol BIS Billing 3.0 (UBL 2.1 XML) — the universal format accepted by all Peppol participants worldwide.
40+ Countries
Peppol is live in the EU, UK, Singapore, Australia, New Zealand, Japan, and expanding rapidly into the Middle East and Latin America.
Regulatory Compliance
Mandatory in Belgium (Jan 2026), rolling out across the EU via ViDA, and adopted by UAE FTA. Peppol is becoming the global default.
AS4 Encrypted Transport
Documents travel over the AS4 protocol — end-to-end encrypted, digitally signed, with full audit traceability and non-repudiation.
Any ERP, Any Size
Whether you use SAP, Dynamics 365, Odoo, or a custom stack — Peppol connects them all. No point-to-point integrations required.

A proven four-step process to install, configure, and activate your Intelligent E-Invoicing Solution guardrail — typically live within days.
Discovery & ERP Audit
