Choosing Accounting Software for a Singapore Company: Xero vs QuickBooks Online
Last updated: 6 September 2026 · Author: SBC Team
The accounting software decision for a Singapore company is settled by seven local criteria, not by the feature list on the vendor’s homepage. The first is GST. Once your taxable turnover passes S$1 million over a 12-month period you must register with the Inland Revenue Authority of Singapore (IRAS) within 30 days, and from that point your software has to produce a return that maps to the boxes on the GST F5 at the current 9% rate, with zero-rated and exempt supplies coded separately.
This guide covers the criteria that matter here, compares Xero and QuickBooks Online against them, notes when you need neither yet, and explains how to move off spreadsheets.
The Seven Criteria That Decide It in Singapore
Global comparisons rank these products on invoice templates, mobile apps and dashboard design. Those differences are real and they matter very little. What follows is what breaks when your first GST return and your first ACRA filing come due.
1. GST Handling and the F5 Return
The GST F5 is the return every GST-registered business files with IRAS, quarterly by default, one month after the accounting period ends. It is a box-by-box form: standard-rated supplies, zero-rated supplies, exempt supplies, taxable purchases, output tax due, input tax claimed, and the net figure. Your software has to produce a report whose lines you read straight onto it. Three things decide whether it does:
- The rate is applied per transaction line at 9%, with historical rates handled correctly for prior-period adjustments.
- Zero-rated supplies (most exports and international services) and exempt supplies (broadly, certain financial services and the sale or lease of residential property) sit in separate boxes, so they need separate tax codes, not one blanket “no GST” code.
- Reverse charge and imported services, where they apply to you, have their own treatment.
The failure mode is not that the software refuses. It is that everything gets coded to one generic zero-rate code, the boxes come out wrong, and nobody notices until IRAS asks. Read the current F5 requirements on the IRAS website and reconcile a test quarter line by line before you commit.
2. The IRAS Accounting Software Register
IRAS publishes a register of software that meets its technical requirements, including generating the IRAS Audit File requested during a GST audit. The listing is narrower than it looks. It is not an endorsement, it does not certify your books, and it does not make your returns correct. It says the product can produce the file IRAS will ask for, in the expected format, for that version. Entries are recorded by product and version and they change, so check the register on iras.gov.sg rather than trusting any comparison table, including this one.
IRAS has also been phasing in a requirement for GST-registered businesses to transmit invoice data through InvoiceNow, Singapore’s Peppol-based e-invoicing network, starting with new voluntary registrants. Check the current scope and dates on the IRAS site, and ask your vendor how they connect to Peppol.
3. Multi-Currency
If you invoice overseas customers or pay overseas suppliers, multi-currency is not optional. Check how the software posts realised and unrealised exchange differences, whether it revalues foreign-currency balances at period end, and whether GST reporting still comes out in Singapore dollars. In both products this is typically a higher-tier feature, so confirm it is in the plan you are quoted.
4. Bank Feeds With Singapore Banks
A bank feed pulls transactions into the ledger automatically. Without one, someone imports statements by hand every month and reconciliation quietly stops happening. Ask the vendor for their current Singapore list, covering DBS, OCBC, UOB and the digital business accounts many founders use, and ask whether each is a direct connection or a file import dressed up as a feed.
5. Payroll and CPF
This is where global comparisons mislead most often. Singapore payroll means Central Provident Fund (CPF) contributions for Singapore Citizens and Permanent Residents at rates that vary by age and wage, the Skills Development Levy on all employees including foreigners, and the IR8A employment income return, which most employers submit through the Auto-Inclusion Scheme.
Neither Xero nor QuickBooks Online ships a Singapore CPF payroll module in the core product. Payroll runs in a connected application that posts journals back into the ledger — well-trodden, but a second subscription and a second implementation. CPF contributions are due by the 14th of the following month, and current rates sit on the CPF Board website.
6. Statements Your Filer Can Convert to XBRL
Most Singapore companies that file financial statements with the Accounting and Corporate Regulatory Authority (ACRA) file them in XBRL against ACRA’s taxonomy, lodged through BizFile. Smaller companies file a simplified version, and whether you file statements at all depends on your company type and solvency.
No general accounting package files XBRL for you. It has to produce a clean trial balance, profit and loss statement and balance sheet, with an account structure your corporate secretary or auditor can map onto the ACRA template without re-keying. Ask them which reports they want before you design the chart of accounts. Requirements sit on the ACRA website; filings go through BizFile.
7. Access for Your Accountant or Corporate Services Provider
Both products let an external accountant work directly in the file, which removes the monthly ritual of emailing spreadsheets. Confirm that adviser access carries no extra per-user charge, and that the company owns the subscription. If the file sits under your provider’s account, changing providers becomes a negotiation. Our tax and accounting services work inside whichever file you own.
Xero and QuickBooks Online Against Those Criteria
Both are mature double-entry systems used by Singapore SMEs, and neither is disqualified by any of the seven criteria. The last column matters most, because capability changes faster than articles do.
| Singapore criterion | Xero | QuickBooks Online | Verify by |
|---|---|---|---|
| GST report in F5 shape | Built around the F5 boxes | Equivalent, at tax-code level | Test quarter vs current F5 |
| Zero-rated and exempt codes | Available; discipline on you | Available; same caveat | Post an export and an exempt item |
| IRAS register and Audit File | Check the entry | Check the entry | Register, by product and version |
| InvoiceNow / Peppol | Feature or access point | Same pattern | IRAS scope for your registration |
| Multi-currency | Higher-tier feature | Higher-tier feature | The plan you are quoted |
| Singapore bank feeds | Direct feeds, several banks | Varies; some file import | Current bank-by-bank list |
| Payroll with CPF | No native module | No native module | CPF, SDL and IR8A output |
| XBRL-ready statements | Standard TB, P&L, balance sheet | Standard TB, P&L, balance sheet | Your filer’s required format |
| Accountant access | Adviser access standard | Accountant access standard | No extra fee; you own the file |
The honest differentiator is not in the table. It is your accountant. Xero is the file our team and most Singapore corporate services providers encounter most often locally, and familiarity shortens month-end close. QuickBooks Online is more often right when group reporting or investors sit in the United States. Choosing the one your finance support cannot work in is the clear mistake.
One further check: confirm the product is actively sold and supported in Singapore. Vendors have withdrawn accounting products from Asian markets before, and Intuit closed QuickBooks Online in India in 2023. That is not a prediction about Singapore. It is a reason to ask about regional commitment and data export before you put five years of records inside a system.
The Other Options, and When You Need Neither Yet
Singapore SMEs also run Zoho Books, Sage, MYOB and ABSS, and several locally focused packages appear on the IRAS register. If your accountant is fluent in one and it clears the seven criteria, use it.
There is also a real case for using neither. A dormant or pre-revenue company with a handful of transactions a year and no GST registration does not need a subscription. A spreadsheet plus the bank statements is enough, provided you keep the records for the statutory five years. Three signals the spreadsheet has run out of road:
- You have registered for GST, or the S$1 million threshold arrives within two quarters.
- You are past roughly 30 to 50 transactions a month, or invoicing in more than one currency.
- You have hired an employee, which brings CPF, payroll records and IR8A into the picture.
Migrating Off Spreadsheets: What to Bring and When
Pick the cutover date first, and make it the first day of a financial year. A mid-year migration carries two sets of records through one reporting period, and every reconciliation gets done twice. What you bring across on day one:
- An opening trial balance at the cutover date, agreed to the prior year’s statements.
- Open customer invoices and supplier bills individually, so aged receivables and payables are real from the start.
- Bank and card balances agreeing to the statement at the cutover date.
- The fixed asset register with cost, accumulated depreciation and remaining useful life.
- A chart of accounts designed for the reports you file, not the software’s default list.
- Customer, supplier and tax-code setup, each tested on a live transaction first.
What you do not do is import years of history for its own sake. You still have to keep the underlying records for five years under the Companies Act, the Income Tax Act and the GST Act, and switching systems does not discharge that. Keep the old file exported and readable for the full period.
If the books are behind, fix that before you migrate — moving a bad trial balance relocates the problem. Our guide to bookkeeping services in Singapore covers what a clean monthly cycle looks like.
The Mistakes That Cost Money Later
Four patterns account for most of the remediation work we see, and none of them are software faults.
No chart of accounts discipline. When accounts get created ad hoc for each unusual transaction, the ledger fills with near-duplicates and the mapping to the ACRA XBRL template becomes a manual exercise every year. Design it once against the statements you must produce, then control who can add accounts.
GST coding errors. Exports coded as standard-rated, exempt supplies lumped in with zero-rated, input tax claimed where the claim is blocked. Each error is small and the pattern is expensive, because correcting it means restating past returns rather than fixing one entry. Review the GST report before every filing.
Mixing personal and company transactions. The company is a separate legal person and its bank account is not your wallet. Personal spending run through it creates a director’s balance that has to be reconciled and explained, and it is one of the first things an auditor or bank reviewer pulls on.
No reconciliation habit. Software that is not reconciled is a filing cabinet with better fonts. Monthly bank reconciliation, within about 15 working days of month-end, is what turns the ledger into something you can file from, and it catches duplicate payments and missing income.
Software Does Not Make You Compliant
No accounting package files anything with ACRA or IRAS on your behalf. The deadlines stay with the company, which in practice means the directors:
- Estimated Chargeable Income — IRAS, within 3 months of financial year-end unless waived.
- Annual return — ACRA, within 7 months of financial year-end for non-listed companies.
- Corporate tax return (Form C-S, C-S Lite or C) — IRAS, by 30 November for the preceding year of assessment.
- GST F5 — IRAS, one month after each accounting period ends.
The corporate tax rate is 17% on chargeable income, with exemptions that reduce the effective rate for qualifying new and small companies. Good software makes those numbers reliable and available on time. It does not file them, and it does not notice when the books are three months behind.
Frequently Asked Questions
Is Xero or QuickBooks better for a Singapore company?
Both clear the Singapore criteria: GST coding for the F5 at 9%, multi-currency on higher tiers, local bank feeds, and reports your filer can map to XBRL. Xero is the file most Singapore accountants and corporate services providers encounter locally. QuickBooks Online suits businesses whose group reporting or investors sit in the United States.
What does it mean if software is on the IRAS accounting software register?
It means IRAS has assessed that product and version against its technical requirements, including generating the IRAS Audit File requested during a GST audit. It is not an endorsement, it does not certify your books, and it does not make your returns correct. Listings change, so check the register on iras.gov.sg.
Do Xero and QuickBooks handle CPF payroll in Singapore?
Not in the core product. Neither ships a Singapore CPF payroll module, so payroll runs in a connected application that posts journals into the ledger. Budget for the second subscription, and confirm it produces CPF contributions, the Skills Development Levy and IR8A output for the Auto-Inclusion Scheme.
Can accounting software file my ACRA financial statements in XBRL?
General accounting packages do not file XBRL for you. They produce the trial balance and statements your corporate secretary or auditor maps onto ACRA’s taxonomy and lodges through BizFile. Design your chart of accounts with that mapping in mind, and ask your filer which reports they want.
When should I move from spreadsheets to accounting software?
Move when any one of three things happens: you register for GST or see the S$1 million turnover threshold arriving within two quarters, you pass roughly 30 to 50 transactions a month or start invoicing in a second currency, or you hire your first employee. A dormant company can stay on a spreadsheet.
When is the best time to switch accounting systems?
The first day of a new financial year. A mid-year cutover means running two sets of records through one reporting period and reconciling everything twice. Bring across an opening trial balance, open invoices and bills individually, bank balances agreed to statements, and the fixed asset register.
If you want the software choice made against your actual filing obligations rather than a feature list, our tax and accounting services cover system setup, monthly bookkeeping, GST returns and corporate tax filing.
