# E-Invoicing - Overview

## Introduction

Singapore is introducing mandatory electronic invoicing (e-invoicing) for B2B transactions. Starting 1 November 2025, newly incorporated companies that apply for voluntary GST registration within six months of incorporation will be required to send invoice data to IRAS. From 1 April 2026, this requirement will extend to all businesses applying for new voluntary GST registration, regardless of their incorporation date or business structure.

**Note:** E-invoicing is available in Zoho Billing only if you integrate your Zoho Billing organization with Zoho Books.

### What is an e-invoice?

An e-invoice is a machine readable invoice issued by a supplier in a structured data format, allowing for automatic processing. This allows the buyer to import it directly into their system, eliminating the need for manual data entry.

### Who is required to send e-invoices?

You are required to adopt e-invoicing if all the following apply:

*   You are applying for voluntary GST registration on or after 1 November 2025.
*   Your business was incorporated within 6 months before the date of your GST registration application.

## How does e-invoicing work in Zoho Billing?

PEPPOL (Pan-European Public Procurement Online) is a standard that allows businesses and governments to securely exchange electronic documents like invoices and credit notes across borders.

In Zoho Billing, when you send an invoice via PEPPOL:

*   The invoice is validated to ensure all required fields are entered.
*   It is then sent from your organization’s PEPPOL access point, Storecove, which handles the secure transmission of the document through the PEPPOL network.
*   The system uses the recipient’s PEPPOL ID to locate their access point.
*   The invoice is delivered through the PEPPOL network to the recipient’s access point.

## Enable E-Invoicing

**Prerequisite:** You can enable e-invoicing only if you’ve enabled taxes in your Zoho Billing organisation.

To enable e-invoicing:

*   Go to _Settings_.
*   Select **E-Invoicing** under _Taxes & Compliance_.
*   Click **Enable E-Invoicing**.
*   Click **Enable E-Invoicing** in the _Enable E-Invoicing_ pop-up that appears.
*   Read and agree to all the terms and conditions in the _Terms and Conditions_ pop-up.

Now, e-invoicing will be enabled for your organization.

## Push Transactions via PEPPOL

To send an invoice or a credit note to a customer via PEPPOL:

**Note:** When transaction approval is enabled, invoices must be approved before they can be pushed to the PEPPOL network. If multi-level approval is configured, invoices can only be pushed after final approval has been obtained.

*   Go to _Sales_ on the left sidebar and select **Invoices**.
*   Select the invoice you want to push to the PEPPOL portal.
*   Click **Send to Customer**.
*   Click **Send** in the pop-up that appears.

The invoice will be sent to your customer through the PEPPOL network.

## Statuses of Transactions in E-Invoicing

The status of each transaction will be displayed in the transaction’s overview page. The statuses of the transactions in e-invoicing are:

## Disable E-Invoicing

Here’s how you can disable e-invoicing in Zoho Billing:

*   Go to _Settings_ on the top-right corner.
*   Select **E-Invoicing** under _Taxes & Compliance_.
*   Click **Disable E-Invoicing** in the top-right corner.
*   Click **Disable** in the pop-up that appears.

E-invoicing will be disabled for your organization.
