Free accounting software can work for Singapore micro-businesses under SGD 1M turnover, but most lack GST compliance and advanced reporting. Upgrade to premium tools when scaling beyond simple invoicing and expense tracking.
Starting a business in Singapore comes with real compliance costs. You'll need to file GST returns with ACRA (if turnover exceeds SGD 1M), manage CPF contributions, and maintain audit trails for five years. For freelancers, sole proprietors, and early-stage startups, free accounting software can bridge the gap between spreadsheets and expensive enterprise systems.
However, most free tools available globally weren't designed for Singapore's 9% GST system or local banking integrations with DBS, OCBC, and UOB. This guide reviews which free solutions work—and where they fall short.
Before comparing tools, understand your core needs:
Wave is completely free and widely used by Singapore freelancers. It supports multi-currency (including SGD), unlimited invoices, and expense tracking. The interface is intuitive and mobile-friendly.
Limitations: Wave's GST support is basic—you'll need to manually calculate GST on invoices. There's no direct bank feed integration for Singapore banks, so you'll import transactions manually. Advanced reporting and financial forecasting are limited.
ZipBooks offers a free tier with core invoicing, expense categorization, and basic financial reports. The dashboard is clean and the mobile app is responsive. It's particularly useful if you invoice international clients.
Limitations: GST compliance isn't built in, and Singapore bank integrations are not standard. Tax reporting is generic and won't align with ACRA requirements. The free tier caps features significantly; most Singapore users upgrade within 6 months.
GnuCash is open-source and free forever. It's desktop-based and highly customizable, with strong multi-currency support and detailed accounting control. Suitable for users comfortable with accounting fundamentals.
Limitations: No cloud sync, outdated UI, steep learning curve, and zero GST or Singapore-specific compliance. Not recommended for non-accountants.
| Tool | Free Tier Cost | GST Support | Bank Integration | Best For |
|---|---|---|---|---|
| Wave | SGD 0/month | Manual only | No Singapore integration | Freelancers, micro-invoicing |
| ZipBooks | SGD 0/month | Manual only | Limited (US-focused) | Small service businesses |
| GnuCash | SGD 0/month | No | No | Accountants, power users |
| Zoho Books | SGD 0/month (limited) | Yes, GST compliant | DBS, OCBC, UOB | Growing SMEs |
Zoho Books deserves special mention because its free tier—while limited—is the only one built for Singapore compliance. It supports GST tracking, integrates with all major Singapore banks (DBS, OCBC, UOB), and generates ACRA-aligned reports. The free version is capped at 1,000 invoices and 2 users.
When to upgrade: Once you exceed 1,000 invoices annually (roughly 80–100/month), Zoho's paid plans start at SGD 29/month and remain competitive for growing SMEs.
Free tools work well if you're a single-person operation with fewer than 50 monthly invoices and minimal expenses. But growth brings complexity. If your business hits any of these milestones, it's time to invest in paid software:
If free software falls short, Xero is the market-leading choice for Singapore businesses. It has full GST compliance, automatic bank feeds from DBS, OCBC, and UOB, mobile invoicing, and expense automation. Pricing starts at SGD 12/month for the Starter plan and scales with features. Most Singapore SMEs use Xero for payroll integration with CPF and annual compliance.
Free software gets you started, but Xero grows with your business. Connect your Singapore bank, automate GST returns, and simplify tax time.
