Trusted by Singapore founders and growing businesses

John-Guy Park

Founder & CEO, Workfutur Pte Ltd.

“I started using Sleek just for this free invoice generator because Excel was driving me crazy. The PDFs look incredibly professional. Eventually, as my business grew, I moved all my accounting over to them. Best software decision I’ve made.“

Andrew Lai

Owner, Aetna insurance Brokers Pte. Ltd.

“I used to spend 20 minutes per invoice in Excel, double-checking my GST math. Now it takes me 90 seconds and I know it’s IRAS-compliant every time. Sleek just works.”

Sophie Chhuon

Founder, POASIA

“Getting the 9% GST and UEN formatting right on manual templates was a headache. This tool takes 60 seconds, and it’s perfectly compliant. When we needed proper corporate tax filing later, Sleek was already there for us.”

Frequently Asked Questions

Is this tax invoice generator really 100% free?

Yes—completely free to create and download as many tax invoices as you need. No account, no credit card. If you want to save your client details for next time and track payments, you can create a free Sleek Accounting account.

Does this template meet IRAS requirements for a Tax Invoice?

Yes. If you are a GST-registered business in Singapore, IRAS requires you to issue a “Tax Invoice” that includes your UEN, the words “Tax Invoice”, and the GST amount clearly separated. Our tool includes all these fields by default and auto-calculates 9% GST.

Can I use this if I'm a freelancer or sole proprietor?

Absolutely. This tool is built for freelancers, consultants, and sole proprietors in Singapore who need to send a professional, compliant bill without paying for expensive accounting software.

What payment methods can I include on the invoice?

There’s a dedicated “Bank Details” section at the bottom of the generator. We recommend adding your PayNow UEN or QR code alongside your corporate bank account number to help clients pay you faster.

What happens to my data after I generate the invoice?

If you use the tool as a guest, your data stays in your browser only—nothing is stored on our servers. If you want your invoices securely saved in the cloud for future access, create a free Sleek account after downloading.

Is this invoice valid for non-GST registered businesses?

Yes. If you are not GST-registered, simply toggle off the GST switch. The tool will generate a standard invoice without GST fields. You can still include your UEN for identification.

Can I add PayNow or bank transfer details?

Yes. The Bank Details section lets you add PayNow UEN, QR code instructions, or standard bank transfer information (bank name, account number, branch code) so your client knows exactly how to pay you.
