Singapore is moving towards the use of a completely digital invoicing system with the introduction of the national e-invoicing program, which is called InvoiceNow and is based on the PEPPOL network. This framework was developed by the Infocomm Media Development Authority (IMDA) of Singapore to assist businesses in the efficient and effective sending and receipt of invoices in a structured electronic format.
With the introduction of GST and the need for GST reporting and validation in the near future, the use of the Singapore PEPPOL e-Invoicing system is an integral part of the businesses in the country. This framework assists the business in automating the invoicing system, which in turn helps in the efficient and effective processing of the invoices without the possibility of errors during the process.
In the article, the framework, compliance, integration, and the smarter way of using the Singapore PEPPOL e-Invoicing system will be discussed.
PEPPOL E-Invoice Structure
The e-invoice structure of Singapore under the PEPPOL follows an international interoperability network that facilitates the exchange of standardized invoices between organizations. This structure was adopted in Singapore as part of the country’s e-invoice system, making it the first non-European country to adopt the system. The structure is overseen by InvoiceNow, which allows organizations to send and receive invoices directly from their accounting systems.
The Singapore PEPPOL framework supports digital invoice exchange between businesses, allowing invoices to move directly from one system to another without manual intervention.
Key Components of the PEPPOL E-Invoice Structure
Supplier System:
This is usually the ERP system of the supplier, which generates structured digital invoices, usually in XML format.
PEPPOL Access Point Provider:
This is the gateway that the organization uses to access the PEPPOL network.
PEPPOL Network Routing:
This uses unique identifiers such as the UEN-based PEPPOL ID for routing the invoices.
Receiver’s Accounting System:
Here, the invoices are processed upon receipt.
Tax Authority Reporting Layer:
In the new structure adopted in Singapore, the possibility of data being sent to IRAS for GST has been included.
In the current structure, the five-corner model has been adopted, which allows for the sending of invoices to other organizations and even the taxman for validation.
Manual vs Automated Invoice Flow
The traditional way of processing invoices involves a series of manual activities, including creating, printing, sending, and processing invoices. This process has a higher chance of error, which might cause a delay in payment processing.
Manual Invoice Workflow
- Invoice created manually using accounting software
- Invoice sent via email or PDF
- Invoice data entered manually into the system by the recipient
- Invoice data might be incorrect, so corrections are necessary
- Invoice approval process delayed
This process makes the financial process slow, leading to increased costs.
Automated Invoice Workflow
However, Singapore has adopted a PEPPOL e-invoicing system, which facilitates automated invoices using a standardized digital format.
The automated process involves:
- Invoice created using the ERP system
- Invoice converted to a PEPPOL-compatible XML format
- Invoice sent using a PEPPOL access point
- Invoice automatically validated and sent
- Invoice automatically imported into the recipient’s accounting system
This automated process helps in the smart invoicing Singapore ecosystem, where invoices are processed automatically, thus avoiding manual intervention.
IMDA Compliance Requirements
To all businesses operating in Singapore, it is essential to comply with PEPPOL compliance standards when using e-invoicing services.
The Infocomm Media Development Authority (IMDA) is the PEPPOL authority for Singapore and is responsible for determining the technical standards and for accrediting access point providers.
Core Compliance Requirements
Use of Certified Access Point Providers
All businesses are required to use the services of approved providers by the Infocomm Media Development Authority (IMDA) to access the PEPPOL network.
Supported Invoice Format
The format for all e-invoices is either the SG PEPPOL BIS Billing 3.0 or the new PINT-SG format.
Unique Business Identifier
The Unique Entity Number (UEN) is used as the PEPPOL ID for all companies to send and receive invoices.
GST Reporting Integration
Certain types of businesses are required to use the services of InvoiceNow for the purpose of GST reporting.
Document Archiving
E-invoices are also archived for future use and for purposes of audit and regulations.
It is also worth mentioning that Singapore is slowly moving towards making PEPPOL e-invoicing a requirement for all GST registered companies and government suppliers while strengthening PEPPOL compliance standards.

ERP & Accounting Integration
The major advantage of using ERP e-invoicing SG solutions is the ability to integrate the PEPPOL framework directly with the ERP or accounting systems of the organization.The majority of ERP and accounting systems are capable of connecting to the PEPPOL network using APIs or middleware offered by access providers.
Integration Process
ERP Invoice Creation:
The invoice is generated using the ERP or accounting system.
Data Mapping:
The invoice data is mapped to the PEPPOL standard format, i.e., XML format.
Access Point Connection:
The invoice is sent to the PEPPOL network using an accredited access point.
Transmission & Delivery:
The invoice is delivered to the recipient’s access point.
Automatic Processing:
The invoice is automatically processed by the recipient’s ERP or accounting system.
Businesses implementing ERP e-invoicing SG systems can significantly improve automation, efficiency, and regulatory compliance in their invoicing processes.
Benefits of Real-Time Validation
One of the key benefits of the Singapore PEPPOL e-Invoicing system is the validation of invoices in real-time.
In contrast to traditional invoicing, which might take days for errors to be detected, the use of the PEPPOL system for invoicing occurs in real-time during the submission of the invoice.
This process also strengthens digital invoice exchange, ensuring that invoices are securely transmitted between systems.
