Best invoicing software in Singapore for businesses (2026)

In 2026, invoicing solutions for small businesses in Singapore increasingly focus on IRAS compliance and InvoiceNow (Peppol) integration.

1. Xero

Xero is a cloud-based accounting software that includes comprehensive invoicing capabilities. Being cloud-based means you need an internet connection to access its full functionality, but this also allows you to manage your finances from anywhere, with mobile access available.

The platform can integrate with your bank account to automatically import transactions, reducing manual data entry. One notable feature is that Xero doesn’t limit the number of users who can access the account, which can be valuable for growing teams.

Key strengths:

• Cloud accessibility from multiple devices and locations
• Unlimited user access on all plans
• Strong integration ecosystem with various business tools
• Automated bank feeds for transaction reconciliation
• Built to meet GST reporting requirements and support InvoiceNow (Peppol) e-invoicing.

Considerations:

• Pricing increases with additional features and transaction volumes
• May have a learning curve for users new to accounting software
• Requires a stable internet connection for optimal performance

2. QuickBooks

QuickBooks is another cloud-based accounting solution widely used in Singapore. Like Xero, it enables collaboration across devices, allowing multiple people to work on your company's finances simultaneously. 

The software provides pre-designed invoicing templates that let you create professional invoices, sales receipts, and estimates quickly. This template-based approach can help maintain consistency in your client communications while saving time on document creation.

Key strengths:

• Professional invoicing templates for quick customisation
• Multi-device collaboration capabilities
• Comprehensive reporting features for financial insights
• Mobile app for on-the-go invoice creation
• Built for GST readiness, with automated tax tracking and integration with local banks.

Considerations:

• Additional charges apply for more than two users
• Pricing tiers can become expensive as business needs grow
• Its InvoiceNow capability often requires third-party access point connectors, which incur additional fees.
• Some features may be more complex than needed for simple invoicing

3. ABSS (formerly MYOB)

ABSS (formerly known as MYOB Singapore) is a long-established accounting software suite popular with small and medium-sized businesses in Singapore. It offers comprehensive invoicing, GST compliance, and broader accounting capabilities. It’s designed to help you manage financial operations in one place.

Key strengths:

• Built-in GST compliance and formatting tailored for Singapore tax reporting.
• InvoiceNow e-invoicing support through ABSS Accounting & Premier Connect for faster, structured invoice delivery and receipts.
• All-in-one accounting suite covering invoicing, payables, receivables, inventory, and financial reporting.
• A.I. Scan and interactive dashboards in cloud-connected versions to streamline data capture and performance insights.
• Flexible pricing with both cloud-connected and traditional on-premise options available
•  Supports InvoiceNow e-invoicing, allowing you to send and receive structured electronic invoices over the Peppol network directly from within the software

Considerations:

• The hybrid desktop/cloud model may not offer the same seamless mobile experience as fully cloud-native platforms.
• Integration options with other business tools (e.g., e-commerce or CRM platforms) are more limited compared with Xero or Zoho Books.
• Some businesses may find the broader accounting feature set more than what’s needed for simple invoicing tasks.

4. Zoho Books

Zoho Books is a cloud-based accounting and invoicing solution designed to help Singapore businesses manage finances, stay GST compliant, and streamline e-invoicing. Its platform supports invoicing, expense tracking, banking, reporting, and more, all within one unified system.

With Zoho Books, you can create professional invoices that automatically apply GST based on customer location and tax settings, reducing manual errors and speeding up billing. The software also integrates Peppol e-invoicing, enabling seamless digital delivery of invoices in compliance with evolving Singapore standards.

Key strengths:

• GST-ready invoicing with automated tax codes and F5 compliance tools
• PEPPOL e-invoicing support for efficient digital transmission
• Cloud-based access with mobile apps for invoicing and accounting on the go
• Comprehensive accounting suite combining invoicing, banking, expenses, and reporting
• Customisable invoice templates and automation for recurring billing

Considerations:

• Full accounting features may be more than needed if you only require simple invoicing
• Some advanced automation and integration options may involve a learning curve for new users
• InvoiceNow submission in Singapore may require third-party connectors for full IRAS compliance in certain workflows

5. Financio

Financio is a cloud-based accounting and invoicing software designed for small and medium-sized businesses, with features to help automate bookkeeping, manage finances and stay compliant with local tax requirements in Singapore. Its platform combines invoicing, expense tracking, reporting, and GST compliance in one system.

Key strengths:

• GST-ready invoicing with InvoiceNow support for faster, compliant invoice transmission.
• Cloud-based access with mobile app support via Financio CONNECT for on-the-go accounting and invoice management.
• Automated bookkeeping: create invoices, record payments and expenses while Financio generates tax records automatically.
• Dashboards and real-time sales/purchase insights help you track business performance at a glance.
  Integration with local bank feeds (e.g., DBS & Maybank) for smoother reconciliation.

Considerations:

• While Financio covers invoicing and accounting well, businesses needing highly advanced features (e.g., deep project accounting or extensive third-party app marketplaces) may find the ecosystem more limited than larger platforms.
• Entry-level pricing plans may cap invoice volumes or reports, incentivising upgrades for heavier use.
• Users new to accounting systems may require a short onboarding period to fully utilise automation and reporting tools.
• Financio’s mix of cloud accessibility, GST compliance, and support for digital invoicing makes it a strong contender for Singapore SMEs seeking a simple yet capable invoicing and accounting platform.

Each option serves different business needs, from free basic functionality to comprehensive cloud-based solutions with extensive integration capabilities.

Benefits of using an invoicing software

Invoicing software offers several practical advantages for small businesses. 

• Improved accuracy: Automates calculations and reduces manual data entry, lowering the risk of billing errors and client disputes.
• Time savings: Uses templates and recurring invoices to avoid repetitive manual work, freeing up time for core business activities.

How to choose invoicing software for your business in 2026

Choosing the right invoicing software means matching your business needs with the features and limitations of each solution. When comparing options, focus on the factors below to determine which platform fits your workflow, budget, and future growth.

Ease of use

The interface should be intuitive enough for you and your team to use with minimal training. Complicated systems can slow down daily operations and increase the risk of mistakes.

Core invoicing features

Look for tools that cover essentials such as recurring invoices, payment tracking, expense recording, and basic financial reporting. These features reduce manual work and help maintain accurate records.

GST compliance

For businesses in Singapore, the software should apply GST correctly, generate GST compliant invoices, and maintain records suitable for IRAS reporting. This helps reduce compliance risks and simplifies tax filing.

Business size and scalability

Your current needs may be simple, but your software should still support growth. Solo businesses with low invoice volumes might manage with basic tools, while growing businesses often benefit from cloud platforms that handle higher transaction volumes and automation.

Integration capabilities

Consider how well the software connects with your existing tools, such as bank accounts, payment gateways, and accounting systems. Strong integrations reduce double entry and improve data accuracy.

Team collaboration

If multiple people handle invoicing or finances, choose software that supports multi-user access. Also, check whether extra users increase subscription costs.

Accessibility

Cloud-based platforms allow access across devices, including mobile, which is useful for businesses that operate remotely or on the go. Desktop-only systems may be more limiting.

Technical comfort level

Some platforms require more accounting knowledge than others. If you prefer straightforward systems with guidance and customer support, commercial solutions may be more suitable than free or open source tools.

Pricing and overall value

Free tools can lower upfront costs but often involve more manual work and fewer features. Subscription software has ongoing fees, but the time saved and errors avoided may justify the expense. Evaluate both cost and efficiency gains.

Free trials and testing

Many providers offer 14 to 30 day trials. Use this period to test the software with real invoices and client data. This helps you assess whether the interface fits your workflow, the features meet your needs, and integrations work smoothly in practice.

By reviewing invoicing software across these criteria, you can make a more informed decision based on how well each option supports your daily operations, compliance requirements, and future growth.

The bottom line

Managing invoices effectively is fundamental to maintaining healthy cash flow in your business. The right invoicing software can streamline this process, reduce administrative burden, and provide clearer visibility into your financial position.
