OCTIS vs Xero vs QuickBooks for Singapore businesses
Prices, plan limits and the InvoiceNow rule that now decides which software you can use.

Otty's short answer
Xero publishes Singapore prices of S$42, S$77 and S$99 per month, with an 80% off first-3-months offer for new customers. QuickBooks lists four plans for 1, 3, 5 or 25 users but its page did not show Singapore prices when we read it. Both offer a 30-day trial. Whichever you pick, GST-registered firms will need InvoiceNow-ready software. Xero suits small teams on price. QuickBooks suits teams that need more users.

What the table does not show
The InvoiceNow rule
IRAS says GST-registered businesses must send invoice data through InvoiceNow-Ready Solutions, in phases. Companies that register for GST voluntarily within 6 months of incorporation started on 1 November 2025. Other voluntary registrants from 1 April 2026. New compulsory registrants and existing firms with supplies of S$200,000 or less follow on 1 April 2028, then S$1 million or less in 2029, S$4 million or less in 2030 and the rest in 2031. Check the IMDA accredited list before you subscribe.
What it will cost you
Xero's Singapore page lists Starter at S$42, Standard at S$77 and Premium at S$99 per month including GST, with 20 invoices and 5 bills on Starter, and multi-currency on Premium only. New customers get 80% off the first 3 months with a promo code, which has no end date on the page. QuickBooks Online has Simple Start for 1 user, Essentials for 3, Plus for 5 and Advanced for 25, each with a 30-day trial. Its pricing page showed no S$ price when we read it.
GST and support
The GST rate in Singapore is 9%, per IRAS. The IRAS page lists IMDA transition grants of S$1,000 for SMEs with free solution packages available until 31 March 2031. Your accountant may prefer one tool, so ask before you choose, and ask who will activate the InvoiceNow submission and register your UEN in the SG Peppol Directory. Aspire lists direct integration with Xero and QuickBooks, and Airwallex lists both too.
Where OCTIS fits
Software does not replace a bookkeeper who understands GST. OCTIS sells accounting and bookkeeping in Malaysia and Hong Kong only, so it does not file GST or keep books for a Singapore company. If your Malaysian or Hong Kong company has a Singapore subsidiary on Xero or QuickBooks, OCTIS bookkeeping can take the foreign figures into the home books. OCTIS is not a bank and has no partnership with any software vendor here. Ask about 10–30% off your current bill.
Frequently asked questions
Is Xero or QuickBooks better in Singapore?
Xero publishes Singapore prices from S$42 per month and an 80% intro discount. QuickBooks offers up to 25 users and multi-currency from its second plan, but its Singapore prices were not visible on its page. Test both on a 30-day trial with your bank feeds and GST.
What is the GST InvoiceNow requirement?
It requires GST-registered businesses to send invoice data to IRAS through InvoiceNow-Ready Solutions on the Peppol network. It is phased: voluntary registrants from 2025 and 2026, then compulsory and existing firms from 1 April 2028 to 2031 by supply size.
Do I need InvoiceNow if I am not GST-registered?
The IRAS requirement applies to GST-registered businesses. If you are not registered, you are not bound by it. Overseas entities and firms liable only under the reverse charge are exempt. Check whether you will register for GST before choosing software.
How much is GST in Singapore?
IRAS lists the current GST rate as 9%. GST-registered businesses charge it on standard-rated sales unless the supply is zero-rated or exempt. Both Xero and QuickBooks add local tax to the plan price, so check whether a price includes GST.
Is there a grant for InvoiceNow software?
IRAS lists IMDA transition grants of S$1,000 for SMEs and S$5,000 for larger businesses, plus free solution packages until 31 March 2031. Terms and eligibility are on the IMDA and IRAS pages, so confirm before you buy.
