E-Invoicing Guides
Understand e-invoicing. Prepare for compliance. Get your business ready.
E-invoicing is changing how businesses create, exchange, and report invoices around the world.
But the requirements are different in every country.
Our E-Invoicing Guides explain the fundamentals in plain language — from what an electronic invoice actually is to country-specific requirements in Singapore, Malaysia, India, and Nepal.
Start with E-Invoicing Basics
What Is E-Invoicing?
An electronic invoice, or e-invoice, is invoice data created and exchanged in a structured digital format that allows it to be processed electronically.
It isn't simply a PDF invoice sent by email.
Depending on the country, businesses may also need to transmit invoice information through a government or approved e-invoicing network.
In this guide:
- What an e-invoice is
- E-invoice vs PDF invoice
- How e-invoicing works
- How ERP software connects with e-invoicing
- Common e-invoicing terminology
- How to prepare your business
How Does E-Invoicing Work?
The exact process varies by country, but the basic principle is simple.
Instead of creating an invoice in one system and manually entering or uploading it somewhere else, your ERP can connect the transaction with the required electronic invoicing process.
This can reduce duplicate entry while keeping invoicing connected to your accounting and business records.

E-Invoice vs PDF Invoice
They're not the same thing.
A PDF may look like an invoice to a person, but e-invoicing is designed so invoice information can also be understood and processed electronically.
| PDF Invoice | E-Invoice |
|---|---|
| Primarily designed to be read by people | Contains structured invoice data |
| Often emailed or downloaded | Electronically exchanged or transmitted |
| May require manual data entry | Designed for machine processing |
| Data may need to be re-entered into another system | Data can flow between connected systems |
E-Invoicing by Country
Singapore: InvoiceNow & GST InvoiceNow
Singapore's nationwide e-invoicing network is InvoiceNow, which is built on the Peppol framework.
Peppol→InvoiceNow→GST InvoiceNow
As Singapore expands GST InvoiceNow, affected GST-registered businesses will need to use InvoiceNow-ready accounting or ERP software to transmit required invoice data to IRAS.
FACT ERP.NG is an IMDA-listed InvoiceNow-Ready solution.

Malaysia: MyInvois
Malaysia's e-Invoice initiative requires businesses within the applicable implementation phases to create electronic invoices that are validated through MyInvois, the system operated by HASiL.
An e-Invoice is structured transaction data — not simply a PDF invoice.

- B2B, B2C and B2G transactions

India: GST E-Invoicing & Auto E-Invoice
India's GST e-Invoicing system requires applicable businesses to report specified invoice information to an Invoice Registration Portal (IRP).
Invoice→IRP→IRN + QR Code→Customer
The IRP validates the information and generates an Invoice Reference Number (IRN) and signed QR code.
With an integrated ERP, this process can happen as part of the invoicing workflow rather than requiring businesses to create the same invoice twice.

- What an IRP is

- Who needs to generate e-Invoices
- GST e-Invoicing turnover thresholds
- B2B vs B2C transactions

Nepal: Electronic Billing / e-Billing
Electronic billing is part of Nepal's move toward more digital tax and invoicing processes.
Businesses operating in Nepal need to understand the electronic billing requirements that apply to them and how their accounting or ERP system fits into those requirements.

Understanding E-Invoicing Technology
What Is Peppol?
Peppol is an international framework that enables businesses and organizations to exchange standardized electronic business documents.
Singapore's InvoiceNow network is based on Peppol.

E-Invoicing and ERP Software
Why integrate e-invoicing with your ERP?
E-invoicing shouldn't mean creating an invoice in your ERP and then entering the same information into another system. When e-invoicing is connected to ERP, invoice information can flow from the original business transaction into the required electronic invoicing process.
This keeps accounting, invoicing, and compliance connected.

Preparing for E-Invoicing
Is Your Business Ready for E-Invoicing?
E-invoicing readiness isn't just about knowing your country's deadline.
Is your software ready?
Your accounting or ERP system needs to support the relevant local e-invoicing requirements.
Is your business data accurate?
Structured electronic invoicing makes accurate customer, supplier, tax, and transaction information increasingly important.
Will you need another system?
Consider whether e-invoicing is built into your ERP or requires a separate tool and duplicate processes.
Are your teams prepared?
Finance, accounting, sales, and operations teams should understand how invoicing workflows may change.
