Which Accounting Software in Singapore Is InvoiceNow-Ready?

Quick Answer: Singapore businesses can explore InvoiceNow-enabled accounting software such as Xero, ABSS, Sage, Financio and QuickBooks through supported integrations. However, businesses must verify the specific product and version against IMDA's current accredited InvoiceNow-Ready Solution Provider list and confirm that GST invoice data submission to IRAS is supported.

Singapore is progressively making GST InvoiceNow mandatory for GST-registered businesses. This means businesses need accounting or invoicing systems capable of transmitting prescribed electronic invoice information through Singapore's Peppol-based InvoiceNow network.

The right software should support everyday bookkeeping while meeting the applicable GST reporting requirements.

1. What Is InvoiceNow-Ready Accounting Software?

InvoiceNow-Ready software connects businesses to Singapore's nationwide electronic invoicing network.

InvoiceNow allows companies to exchange structured electronic invoices through compatible systems rather than manually processing emailed documents.

For businesses covered by the GST InvoiceNow Requirement, the solution must also support prescribed invoice data submission to IRAS.

Important capabilities include:

• Sending and receiving structured electronic invoices.

• Registering or connecting a Peppol ID.

• Processing invoices and credit notes.

• Supporting applicable Singapore invoice specifications.

• Submitting prescribed GST invoice data to IRAS.

• Providing submission status and error information.

Important: Ordinary Peppol e-invoicing functionality alone does not prove that a particular software version meets every GST InvoiceNow reporting requirement.

2. Which Accounting Software Supports InvoiceNow in Singapore?

The following software products have published InvoiceNow capabilities or appeared in official IMDA provider listings.

Verification note: This is not a claim that every edition or subscription of these products is currently accredited for mandatory GST submission. Businesses should check the current IMDA listing, supported product version and available IRAS submission features before choosing.

3. Which InvoiceNow Software Is Suitable for Small Businesses?

Small businesses should first identify whether they need full accounting functionality or only basic electronic invoicing.

A freelancer may primarily need customer invoices, expenses and payment tracking.

A trading business may require inventory management, supplier invoices and purchase reconciliation.

A larger company may need ERP connectivity, approval workflows and multiple user permissions.

For example, Xero may appeal to businesses preferring cloud accounting, while ABSS may suit organisations accustomed to more traditional accounting workflows.

The most useful solution is one that supports both the business's daily operations and its applicable compliance obligations.

4. Are Free InvoiceNow-Ready Solutions Available?

Yes. Singapore provides free-of-charge basic InvoiceNow solution packages to help qualifying businesses adopt the network.

According to IRAS, these packages are available through 31 March 2031, with provider lists and package terms published for specified periods.

Free solutions may provide basic electronic invoicing and required GST InvoiceNow functions.

However, a free e-invoicing package may not include advanced accounting, inventory management or bank reconciliation.

Businesses should check:

• Eligibility for the free package.

• Invoice or usage limits.

• Included GST reporting features.

• Data export and backup options.

• Charges for additional services.

Free electronic invoicing should not be confused with a permanently free, full-featured accounting system.

5. How Can Businesses Verify Whether Software Is InvoiceNow-Ready?

The most reliable approach is to check the current IMDA-accredited provider directory.

Businesses should:

1. Visit the official IRAS GST InvoiceNow Requirement page.

2. Open the current IMDA-accredited InvoiceNow-Ready Solutions list.

3. Search for the software product and provider.

4. Confirm the supported product version.

5. Ask whether GST data submission to IRAS is included.

6. Verify whether additional modules or charges apply.

7. Test successful invoice data submission.

This prevents a business from purchasing software based only on an advertisement stating that it supports Peppol.

6. Is InvoiceNow Mandatory for All GST-Registered Businesses?

Singapore is implementing the GST InvoiceNow Requirement in phases.

Specified overseas entities and reverse-charge-only registrants are excluded.

Businesses should confirm their assigned implementation date rather than assuming the same deadline applies to every company.

7. Can InvoiceNow Software Also File GST F5 Returns?

Some accounting systems support Singapore GST return preparation or electronic filing, but not every InvoiceNow-enabled product offers direct GST F5 submission.

The two functions are different.

Businesses should verify these features individually.

IRAS's Accounting Software Register Plus provides additional information about certain accounting software products and their listed tax-related capabilities.

8. How Should Businesses Choose InvoiceNow-Ready Software?

Businesses should prioritise verified Singapore compliance, reliability and ease of use before making a purchasing decision.

A suitable system should support accurate invoices, appropriate GST categorisation, customer and supplier records, financial reporting and accessible transaction history.

For businesses with basic accounting requirements, Vinimay offers general invoicing, purchase tracking, customer management and accounting records.

However, Vinimay's Singapore InvoiceNow accreditation, Peppol integration and GST submission capabilities have not been independently verified. Businesses should not rely on it for mandatory Singapore GST InvoiceNow compliance without confirmation.

The practical approach is to shortlist products, verify their accreditation and test the required invoice submission process before committing.
