If you run a small business in Singapore, you’ve probably had this moment: the work is done, the invoice is sent … and then?

Nothing. No payment. No follow-up. Just silence.

Late payments aren’t just frustrating; they can quietly choke a business. A recent report from the Singapore Commercial Credit Bureau (SCCB) revealed that slow payments are becoming more common among Singapore businesses¹.

And when you’re a small business, that cash flow gap can hurt. You put hiring on hold. You delay marketing plans. You hesitate over that new piece of software you need. All because someone hasn’t paid you yet.

That’s where a reliable invoicing software designed for a small business can make a huge difference. It takes the guesswork out of getting paid by giving you templates, auto-filled client details, and built-in checks, making invoices easy to send, easy to pay, and hard to ignore.

In this guide, we’ll walk you through:

What invoicing software does (and why small businesses need it)

Here’s an awkward truth that often gets overlooked:

Slow payments aren’t always the client’s fault.

Maybe the invoice got buried. Maybe the client didn’t have an easy way to pay. Or maybe you accidentally sent the wrong invoice (with the wrong amount, due date, or client) and didn’t realise until it was too late.

Invoicing software helps you create, send, and track invoices. But when you’re running a small business, it solves much more than that:

You can invoice from anywhere. On-site, in a taxi, or in-between meetings? Most invoicing software Singapore solutions are cloud-based, which means you can invoice from your phone, wherever you are.
Clients pay you faster. Offer online payment options (such as card, Stripe, or PayNow) so clients can pay on the spot, keeping your cash flow moving smoothly.
You avoid awkward mistakes. No more sending the wrong invoice, billing twice, or forgetting to include something — it keeps things clear and professional.
Makes you look credible. Polished invoices help you come across as reliable and established, even if you’re a one-person team.

Details correct at time of research — 27th May 2025

Xero

Best if you want:

A powerful, professional platform that handles invoicing, payments, and collaboration with optional add-ons for advanced business functions.

Why it works for you:

If you’re looking for an invoice software for your small business that does more than send bills, Xero² delivers built-in quotes, recurring billing, and payment reminders.
You can add unlimited users on every plan, making it ideal if you collaborate with accountants or admin staff.
It seamlessly integrates with Stripe, PayPal, and local banks, making it easy to accept payments and automatically reconcile them.
Xero also integrates with Wise Business, which allows you to get account details to receive payments like a local, and then sync them directly into your accounts.
If you need more than just basic invoicing, you can add claim expenses (starting from S$6 per month) to track out-of-pocket spending and project tracking (starting from S$10 per month) to manage time, costs, and profitability.

Limitations:

Those advanced features (project tracking and expense management) aren’t built into the standard plans; they’re add-ons with additional fees.
Xero is feature-rich, which is great long-term, but there’s an initial learning curve if you’re new to cloud accounting.

QuickBooks Online

Best if you want:

Something simple, flexible, and easy to run from your phone, whether you’re on your own or have a small team.

Why it works for you:

QuickBooks Online⁷ is one of the most popular picks when choosing an invoicing software suitable for a small business because of its intuitive interface and mobile-first design.
Multi-currency support is included in the Essentials, Plus, and Advanced tiers — perfect if you’re billing overseas clients or paying vendors in different currencies.
You can scale up as your business grows, adding features and users as needed.
Plans are priced in SGD, making them easy to budget for locally.
If you’re using Wise Business, QuickBooks Online lets you sync bill payments directly. That means if you need to pay invoices billed in a foreign currency, you can pay at the mid-market rate using Wise and match them in QuickBooks automatically for easy reconciliation.

Limitations:

The base plan (Simple Start) only supports 1 user, plus an accountant; you’ll need to upgrade to collaborate with teammates.
Features like inventory tracking and time tracking are only available in the higher tiers.
While customisable, it offers fewer deep automation options than platforms like Zoho or Xero.

NetSuite

Best if you are:

Scaling fast or already operating across multiple entities, and need complete control across your business.

Why it works for you:

NetSuite¹⁰ isn’t just an invoice software designed for a small business; it’s a full ERP platform that helps you manage operations, revenue, and reporting from one place.
You can handle advanced billing types, such as subscriptions, tiered pricing, or consolidated client invoices.
If you’re juggling multiple departments or global operations, it centralises everything into one clean system.

Limitations:

Pricing is custom, and not small-business friendly unless you’re managing a high operational volume.
Requires setup and training; not a plug-and-play solution.
May be too heavyweight if you’re just trying to get invoices out the door.

FreshBooks

Best if you are:

A freelancer, solo consultant, or creative service provider who invoices by project or tracked time.

Why it works for you:

You can track your hours, log expenses, and turn everything into a branded invoice in just a few clicks.
Clients have their own portal to review, approve, and pay invoices, eliminating the need for back-and-forth communication.
You can set up recurring invoices or retainers for regular clients and even create proposals directly in the platform.
The mobile app is lightweight and functional — perfect for those who bounce between meetings or clients.

Limitations:

The Lite plan only supports 5 clients and 1 user, which can become limiting quickly.
Pricing is in USD, so Singapore businesses might need to factor in foreign transaction fees and hidden exchange rate markups when paying their FreshBooks bill.
Lacks deeper features like multi-user team collaboration or native inventory tools.

💡Whether you're paying for overseas business transactions such as your SaaS subscriptions or travel expenses, the Wise Business Card lets you spend online or in-store in 40+ currencies and 150+ countries.

Zoho

Best if you want:

Powerful automation, deep customisation, and a free plan to get started, especially if you’re already using other Zoho tools.

Why it works for you:

Zoho Books¹³ is one of the few invoicing software for small business tools that offers a genuinely usable free plan — great if you’re just starting out.
You can automate almost everything, including reminders, approvals, recurring invoices, and workflows based on invoice size or client history.
As you grow, you can unlock project tracking, advanced analytics, and support for up to 15 users.
If you’re already in the Zoho ecosystem (CRM, Projects, Inventory), everything talks to each other smoothly.

Limitations:

Pricing for paid plans is in USD, so again, you will need to factor in the costs of foreign transaction fees and exchange rate markups if you're going to pay your subscription using a corporate bank card.
The dashboard is packed with features, which can be overwhelming for first-time users.
Limited third-party integrations compared to tools like Xero.

How to pick the right invoicing software for your small business

Let’s be honest. You likely don’t need the fanciest invoice software on the market. You just need something that makes sense for the way you work, whether that’s sending a few invoices a month or managing multiple recurring clients across borders.

Here’s what to consider when picking the right invoicing software for your small business:

Only sending a handful of invoices per month? You don’t need to pay for a full-blown accounting suite. A simple option, such as Zoho Books’ free plan or the Wise invoice generator, might cover exactly what you need.
Handling monthly retainers or subscription clients? If your revenue comes in regularly, go for invoicing software Singapore businesses trust for recurring billing. Tools like FreshBooks and Zoho Books let you automate those invoices, so you never forget to bill (and your client never forgets to pay).
Working with overseas clients or planning to scale globally? Multi-currency support isn’t just a nice-to-have. It’s essential. QuickBooks (Essentials and above) and Xero both support invoicing in different currencies. Plus, they integrate with Wise Business multicurrency account which allows you to receive payments in multiple major currencies like USD, EUR, or GBP like a local.
Planning to grow your team or collaborate with others? Many invoicing software for small business plans limit you to one user unless you upgrade. If you’ve got a bookkeeper or are planning to outsource admin, tools like Xero (which allows unlimited users from the start) save you from awkward permission workarounds or extra fees later.

Bottom line: the best invoicing software Singapore businesses choose is the one that fits your current stage, but won’t hold you back when things start moving faster.

Conclusion

Choosing the right invoicing software for your small business isn’t just about making admin easier; it’s about setting your business up to grow.

Because when invoicing is manual, inconsistent, or locked inside spreadsheets, it doesn’t just waste your time — it stalls your momentum. Payments get delayed. Things fall through the cracks. You hesitate to scale because the back-end can’t keep up.

The right software changes all that.

It helps you stay on top of payments, look professional from day one, and handle more clients without adding more hours to your day.

And when you do grow, whether that means bringing on a team, billing in multiple currencies, or entering new markets, the right tool grows with you.

💡 But here’s the thing. While researching what’s the best invoicing software Singapore businesses rely on, it’s just as important to consider whether your business account integrates easily with the software you choose. That’s where Wise Business really shines. It syncs with popular tools like Xero and QuickBooks, making reconciliation faster and more accurate. You can connect your accounts in real-time, which means no more manual matching and no more late nights sorting through spreadsheets.

But the benefits of Wise Business go far beyond clean integrations.

Used together with the Wise Business card, you can hold, receive, send, and spend in multiple currencies, always at the mid-market rate. You won’t have to worry about monthly account fees, bloated exchange rate markups, or surprise foreign transaction fees eating into your margins. Whether you’re invoicing your first client or managing a growing list of global accounts, pairing the right invoicing software for your small business with Wise gives you more than convenience — it gives you confidence, control, and room to scale.
