E-invoicing (electronic invoicing) is the exchange of invoice documents between a supplier and a buyer in an integrated electronic format. It replaces the traditional paper-based invoicing process and can be automated for improved accuracy, efficiency, and compliance. E-invoicing ensures that invoices are digitally transmitted and processed, reducing errors, manual intervention, and processing time.
Benefits of E-Invoicing:
1. Cost Savings: Reduces paper, printing, postage, and storage costs.
2. Efficiency: Streamlines invoice processing and approval workflows.
3. Accuracy: Minimizes manual data entry errors.
4. Compliance: Ensures adherence to regulatory requirements and standards.
5. Environmental Impact: Reduces paper consumption and waste.
6. Faster Payments: Accelerates the invoicing and payment cycle.
Architecture of E-Invoicing
The architecture of e-invoicing typically involves several key components and processes:
1. Invoice Generation:
- Supplier's ERP System: The supplier generates an invoice using their ERP or accounting system.
- Standardization: The invoice data is converted into a standardized electronic format, such as XML, EDIFACT, or UBL (Universal Business Language).
2. Transmission:
- E-Invoicing Network/Platform: The standardized invoice is transmitted via an e-invoicing network or platform, which acts as an intermediary between the supplier and the buyer.
- Communication Protocols: Secure protocols like AS2, SFTP, or API are used for data transmission.
3. Validation and Compliance:
- Validation: The e-invoicing platform validates the invoice against predefined rules (e.g., format, mandatory fields).
- Compliance: The invoice is checked for compliance with tax regulations and other legal requirements.
4. Delivery and Receipt:
- Buyer’s ERP System: The validated and compliant invoice is delivered to the buyer’s ERP or accounting system.
- Acknowledgment: The buyer's system may send an acknowledgment receipt back to the supplier.
5. Processing and Payment:
- Invoice Matching: The invoice is matched with purchase orders and goods receipt notes.
- Approval Workflow: The invoice goes through the buyer's internal approval workflow.
- Payment: Upon approval, the invoice is scheduled for payment.
6. Archiving:
- Digital Archive: Both supplier and buyer archive the e-invoices for future reference and compliance purposes.
Example of E-Invoicing Process Flow:
1. Supplier: Creates an invoice in their ERP system.
2. ERP System: Converts the invoice to a standardized electronic format.
3. E-Invoicing Platform: Transmits the invoice to the buyer.
4. Validation: The platform validates the invoice.
5. Compliance: The invoice is checked for compliance.
6. Delivery: The invoice is delivered to the buyer's ERP system.
7. Acknowledgment: The buyer’s system acknowledges receipt of the invoice.
8. Processing: The invoice is matched, approved, and scheduled for payment.
9. Archiving: The invoice is archived digitally.
E-Invoicing Standards and Protocols
1. Standards:
- PEPPOL: Pan-European Public Procurement Online, used widely in Europe.
- ANSI X12: Common in North America.
- EDIFACT: Used internationally for EDI (Electronic Data Interchange).
- UBL: Universal Business Language, a standard for e-business documents.
2. Protocols:
- AS2: Applicability Statement 2, a secure and widely used protocol for transmitting EDI messages.
- SFTP: Secure File Transfer Protocol, used for secure file transfers.
- API: Application Programming Interface, allows systems to communicate directly.
