Most Singapore business owners see a full set of accounts once a year, sign them, and file them. By that point the numbers are history, and any problem they reveal has been running for months. Tracking a short list of monthly KPIs closes that gap, and it needs neither expensive software nor a finance director.
This article sets out the monthly KPIs worth tracking, why each earns its place, and how to build a reporting habit that survives a busy quarter.
Who this applies to
Monthly KPIs suit almost any trading business, but they matter most if you fall into one of these groups:
- Owner-managed private limited companies where the director is also the main decision maker
- Sole proprietorships and partnerships that have outgrown the bank balance as a guide
- Businesses approaching the S$1 million taxable turnover mark and needing to plan for GST registration
- Companies that pay a bookkeeper but only receive a year-end file, with nothing in between
Key rules and requirements in Singapore
No Singapore statute tells you which KPIs to track, and IRAS does not audit your dashboard. KPI tracking is a management practice, not a compliance obligation.
What the law does require is the raw material that makes KPIs possible:
- Proper accounting records. Section 199 of the Companies Act requires accounting records that sufficiently explain a company’s transactions and financial position, retained for five years. Records good enough to satisfy this are good enough to produce monthly KPIs.
- IRAS recordkeeping. Supporting records must generally be kept for five years from the relevant Year of Assessment. Reconstructing a year of transactions in March costs far more than closing each month as you go.
- Estimated Chargeable Income. ECI is generally due within three months of your Financial Year End, subject to the waiver conditions IRAS applies. Estimating it is guesswork if you have not tracked profitability during the year.
- GST registration. Compulsory registration is triggered when taxable turnover exceeds S$1 million, assessed on both a retrospective and a prospective basis. Businesses that ignore rolling turnover tend to find the threshold after crossing it.
- CPF contributions. Employer CPF contributions are payable monthly and due by the 14th of the following month, with late payment interest after that.
- Directors’ duties. Directors must act in the interests of the company, which is difficult without a current view of cash and profitability.
Nobody will fine you for skipping monthly KPIs. But these obligations already force you to maintain the underlying data, so turning it into a one-page monthly view costs very little.

Step-by-step process
Step 1: Close the month properly, and quickly. Aim to reconcile the previous month within ten working days: bank accounts, sales invoices, supplier bills, payroll with employer CPF, and obvious accruals. KPIs built on an unreconciled ledger are worse than none, because they carry false confidence.
Step 2: Choose eight to ten measures and stop there. This set covers most owner-managed businesses in Singapore.
Profitability
- Revenue growth, month on month and against the same month last year. The year-on-year view strips out seasonality.
- Gross profit margin. The single most diagnostic number in most businesses. A falling margin at rising revenue usually means pricing has slipped or delivery costs have crept up.
- Net profit margin, read as a trend rather than a monthly verdict, because overheads land unevenly.
Cash
- Operating cash flow, the cash actually generated by trading, as distinct from accounting profit.
- Cash runway, closing cash divided by average monthly cash outflow. In months, it is the number most likely to change a director’s behaviour.
- Debtor days. A rising figure is the earliest reliable warning that a cash squeeze is coming.
- Creditor days. If you pay suppliers faster than customers pay you, you are financing your own customers.
Compliance early warnings
- Rolling 12-month taxable turnover, watched against the S$1 million GST registration threshold.
- Payroll as a percentage of revenue, including employer CPF, usually the largest and least flexible cost line.
Customers and productivity
- Revenue per employee, a rough test of whether headcount growth is paying for itself.
- Customer concentration. Anything above roughly a third of revenue from one client is a risk worth naming out loud.
Step 3: Write down each definition and set a baseline. Decide once whether debtor days uses month-end receivables or an average, then never change it midstream. Three months of history shows what normal looks like, and your own trend matters more than another company’s benchmark.
Step 4: Fix a date and act on two things. Put a recurring review in the calendar, read the pack, and pick the two worst-moving numbers to act on. Reviewing ten metrics and changing nothing is reporting, not management.
Common mistakes to avoid
- Watching revenue alone. It is the easiest number to grow, and the easiest to grow unprofitably.
- Treating profit as cash. A profitable month with slow debtors and upfront supplier payments can still empty the bank account.
- Closing the month six weeks late. By then the numbers are commentary, not a decision tool.
- Redefining metrics. Quietly changing how a ratio is calculated makes the trend meaningless.
- Ignoring rolling turnover. Late GST registration creates backdated liability and avoidable penalties.
Practical examples
A services firm watching its margin. A consultancy records September revenue of S$180,000 against direct delivery costs of S$99,000. Gross profit is S$81,000, a margin of 45 per cent. Operating expenses of S$63,000 leave a net profit of S$18,000, or 10 per cent. Revenue is up on August, so the owner is pleased. But gross margin was 52 per cent three months ago. The extra revenue came from a discounted client consuming too much senior staff time.
The same firm reading its debtor days. Trade receivables at month end are S$220,000. Against September revenue of S$180,000, debtor days work out at roughly 37, up from 28 the previous month. At about S$6,000 of revenue a day, those nine extra days leave close to S$54,000 sitting in customers’ accounts. Nothing in the profit and loss account flags this.
A retailer approaching the GST threshold. A shop tracks rolling 12-month taxable turnover and reaches S$870,000 in September, climbing by roughly S$25,000 a month. That puts the S$1 million threshold about five months away. Seeing it coming leaves time to review pricing, update the point-of-sale system and register on schedule rather than retrospectively.

How a corporate secretary can help
A corporate secretary’s core role sits on the statutory side: maintaining registers, preparing AGM and annual return filings within ACRA deadlines, and keeping records accurate on the BizFile+ portal. That work depends on accurate underlying data, which is why corporate secretarial and accounting support sit together.
Raffles Corporate Services can join the two up: monthly bookkeeping and management accounts, so the KPI pack falls out of the close rather than becoming a separate chore, monitoring of rolling turnover against the GST registration threshold, payroll with correct CPF contributions, and ECI, the corporate tax return and unaudited financial statements at Financial Year End. One team seeing both the monthly numbers and the annual filings removes most of the reconciliation pain owners otherwise absorb in March.
Requirements may change, so always check the latest guidance from ACRA, IRAS or MOM, or consult a professional adviser.
Frequently Asked Questions
How many KPIs should a small company track?
Between five and ten. Fewer than five and you will miss something material. More than ten and the review becomes a reading exercise rather than a decision-making one.
Are monthly management accounts required by law in Singapore?
No. The Companies Act requires proper accounting records and, for most companies, annual financial statements, but it does not mandate monthly reporting. Monthly accounts are a management choice that makes the annual obligations easier to meet.
How do I calculate debtor days?
Trade receivables at month end, divided by revenue for the month, multiplied by the days in the month. Whichever formula you choose, apply it consistently so the trend stays comparable.
When do I need to register for GST?
Compulsory registration applies once taxable turnover exceeds S$1 million, assessed retrospectively over the past calendar year and prospectively where you reasonably expect to cross it. Tracking rolling 12-month turnover is the practical way to see it coming. Confirm current rules on the IRAS myTax Portal.
Key takeaways
- No Singapore law requires KPI tracking, but the Companies Act, IRAS and CPF obligations already require the records behind them.
- Close each month within roughly ten working days. Stale numbers cannot drive decisions.
- Track a short list: revenue growth, gross and net margin, operating cash flow, cash runway, debtor and creditor days, payroll as a share of revenue, and customer concentration.
- Watch rolling 12-month taxable turnover against the S$1 million GST registration threshold before you cross it.
- Define each KPI once and keep it fixed, so the trend stays meaningful.
