# Introduction

> Welcome to e-invoice.be - International Peppol Access Point

## What is e-invoice.be?

e-invoice.be is a **recognised Peppol Access Point and SMP** operating under the Belgian Peppol Authority (BOSA). We enable businesses worldwide to send and receive electronic invoices via the Peppol network.

### Switch to e-invoicing, keep your workflow

We've built comprehensive tools to make integrating e-invoicing as simple as possible - even for companies with legacy ERP systems. Our API lets you:

* Send invoices from **JSON** (simple integration)
* Upload **pre-generated UBL XML** (ERP compatibility)
* Create invoices from **PDF files** (legacy system support)
* Integrate via our **reseller programme** (for SaaS platforms)

As a member of the **Peppol Security Committee**, we're committed to maintaining the highest standards of security and compliance in e-invoicing.

## Who We Serve

We provide Peppol e-invoicing services to:

* **Individual companies** across many industries (manufacturing, services, retail, etc.)
* **Public and private listed companies**
* **SaaS companies** through our reseller programme ([contact us](mailto:support@e-invoice.be) for details)
* **Public and government agencies**
* **Companies with or without ERP systems**

<Note>
  Peppol is the international standard for electronic invoicing. E-invoices sent via Peppol are legally compliant with the EU's e-invoicing mandate (EN 16931) and recognized globally.
</Note>

## How Peppol Works

The Peppol network uses a **4-corner model** to enable secure, standardized e-invoice exchange between businesses:

1. **Corner 1**: Your business (the sender)
2. **Corner 2**: Your Access Point (e-invoice.be)
3. **Corner 3**: Recipient's Access Point
4. **Corner 4**: Recipient's business

e-invoice.be handles all the technical complexity of Peppol transmission, so you can focus on your business.
