In today's digital economy, electronic invoicing (e-invoicing) has evolved from a nice-to-have to a legal necessity in many countries. Governments around the world are enforcing e-invoicing standards to streamline tax reporting, curb fraud, and improve transparency in financial transactions. For businesses, this shift represents both a compliance obligation and an opportunity to enhance operational efficiency.
Odoo, a powerful open-source ERP platform, offers robust e-invoicing features that not only help organisations remain compliant with local and international regulations but also automate and optimise the invoicing process. In this article, we’ll explore how e-invoicing works, why it matters, and how Odoo empowers businesses to stay compliant and efficient.
Understanding E-Invoicing: A Quick Overview
Electronic invoicing, or e-invoicing, is the digital exchange of invoice documents between a supplier and a buyer using a standardised format. It eliminates the need for paper-based invoices or PDFs and ensures that the invoice data is transmitted, validated, and stored in a legally accepted manner.
Key Benefits of E-Invoicing:
- Regulatory compliance with national tax systems
- Faster processing and reduced manual errors
- Real-time tracking and better cash flow visibility
- Lower operational costs
- Improved data accuracy and security
Governments in the EU, India, Brazil, Mexico, Saudi Arabia, and many others have already mandated or are planning to mandate e-invoicing for B2B and B2G transactions.

Odoo offers built-in features that allow businesses to create, send, and manage e-invoices directly from its ERP platform. Its flexibility and modularity make it a perfect solution for companies of all sizes that need to comply with evolving e-invoicing regulations.

Global E-Invoicing Compliance with Odoo
Governments are enforcing e-invoicing in specific formats and timelines. Let’s look at how Odoo helps businesses stay compliant across different jurisdictions:
1. India
India’s e-invoicing mandate applies to companies above a specified turnover threshold. Odoo integrates with the Invoice Registration Portal (IRP) to:
- Generate IRNs (Invoice Reference Numbers)
- Include QR codes
- Push data to the GSTN network
2. Italy
Italy uses the Sistema di Interscambio (SDI) for B2B and B2G invoicing. Odoo enables:
- FatturaPA XML generation
- Submission to SDI
- Error-handling and feedback integration
3. Mexico
The Mexican government requires CFDI (Comprobante Fiscal Digital por Internet) format. Odoo supports:
- Automatic CFDI generation
- PAC (Authorized Certification Provider) integration
- Digital stamps and compliance checks
4. European Union (Peppol)
Odoo’s integration with Peppol ensures that EU businesses can exchange standardised e-invoices with public authorities and private businesses.
How E-Invoicing Works in Odoo: Step-by-Step
Implementing e-invoicing with Odoo is straightforward. Here’s a simplified step-by-step process:
Step 1: Create the Invoice
Using the Odoo Accounting or Sales module, generate an invoice just as you would with any traditional transaction.
Step 2: Validate and Convert
Odoo validates the data and automatically converts the invoice into the required XML or UBL format for submission.
Step 3: Digital Signature (if required)
The invoice is digitally signed to comply with legal requirements and ensure authenticity.
Step 4: Submit to Tax Authority or Network
Odoo connects to the required government portal (e.g., SDI, IRP, SAT) or network (Peppol) and submits the invoice for approval.
Step 5: Receive Acknowledgment
The system receives the status update—approved, rejected, or pending—and displays it in your Odoo dashboard.
Step 6: Share with Customer
Once validated, the invoice is automatically shared with the customer via email or electronic delivery systems.
