ACCOUNTING GUIDE · SINGAPORE
Outsourced accounting for Singapore SMEs
Clean books, reliable filings and useful financial reporting—without having to build an accounting department before your business needs one.
What outsourced accounting actually means.
Outsourced accounting means an external team runs some or all of your finance function under an agreed scope. That can begin with monthly bookkeeping and expand to management accounts, corporate tax, GST, payroll and CFO-level advice.
You still make the business decisions. The difference is that the records, reporting and filing process no longer depend on you finding a quiet weekend to catch up.
WHEN TO OUTSOURCE
Four signs the current setup is costing you.
Your books are always catching up
Bank reconciliations, receipts and invoices pile up until a filing deadline forces everything to the top of the list.
You cannot see the numbers clearly
You know what is in the bank, but not which customers owe you, where margins are moving, or what tax is coming.
Compliance lives in one person’s head
Deadlines depend on the founder, an administrator or a spreadsheet reminder rather than a repeatable process.
The work has outgrown DIY bookkeeping
GST, payroll, multiple sales channels or a growing transaction count have made the old setup fragile.
WHAT CAN BE INCLUDED
One scope, built around the work you need handled.
Day-to-day bookkeeping
Transactions categorised, accounts reconciled, and records kept current instead of rebuilt at year end.
Management reporting
Regular profit and loss, balance sheet and useful reporting so decisions are based on more than the bank balance.
Tax and statutory filing
ECI, corporate income tax and relevant ACRA reporting prepared from books that are already in order.
GST support
Registration guidance, transaction treatment and GST returns for businesses that are registered or approaching the threshold.
Payroll coordination
Monthly payroll, CPF submissions, payslips and employee tax reporting when included in your scope.
A financial sounding board
Someone who can explain what the numbers mean and flag issues before they become filing-season surprises.
OUTSOURCED VS IN-HOUSE
The right answer depends on the work, not company size alone.
| Factor | Outsourced accounting | In-house accounting |
|---|---|---|
| Best fit | SMEs that need a reliable finance function without building a full internal team. | Businesses with enough daily complexity and volume to keep finance staff fully occupied. |
| Coverage | Access to bookkeeping, tax, GST and payroll capability within an agreed scope. | Depends on the skills and seniority of each person hired. |
| Management | The provider manages the accounting workflow; you provide timely records and approvals. | You recruit, train, supervise and provide cover during leave or turnover. |
| Control | Clear service scope, reporting rhythm and access arrangements need to be agreed. | Direct day-to-day control and closer physical access to the finance function. |
| Scaling | Scope can expand as transactions, GST, payroll or reporting needs grow. | Capacity usually grows by changing roles or adding headcount. |
A hybrid model can work too: internal staff manage daily operations while an external firm handles reporting, tax and specialist compliance.
MOVING THE WORK
A clean handover in four steps.
Understand the current state
Review your entity, financial year end, filing status, accounting records, bank accounts, payroll and GST position.
Agree the scope
Define who handles invoicing, payments, bookkeeping, payroll, filings, reporting and document collection.
Clean up and migrate
Bring opening balances and overdue reconciliations into order, then establish access to the agreed systems.
Set a monthly rhythm
Choose cut-off dates, document handover, review points and reporting dates so the process stays predictable.
What to ask before choosing a provider.
- Exactly what is included, excluded and charged separately?
- Who owns each monthly task, and what must your team provide?
- How often will the books be closed and reports delivered?
- Who reviews the work and answers accounting or tax questions?
- How are records, approvals and account access protected?
- What happens when transaction volume or business complexity increases?
- How will historical errors or overdue filings be handled?

Common questions.
How much does outsourced accounting cost in Singapore?
The cost depends on transaction volume, filing requirements, payroll, GST, reporting frequency and the condition of the existing books. Synergy’s starting packages currently range from $90 to $650 per month, with bespoke quotes where the scope differs.
Is outsourced accounting only for very small businesses?
No. It can suit early-stage companies that need basic compliance as well as established SMEs that need monthly reporting, payroll, GST and advisory support without building a full finance department.
Do I lose control of my finances when I outsource?
You should retain access to your accounting records and visibility over approvals, filings and reports. The engagement should make responsibilities, access and reporting dates explicit.
Can I outsource only bookkeeping?
Yes. The scope can cover bookkeeping alone or combine it with tax, GST, payroll, financial statements and advisory work. The right scope depends on what you can manage reliably in-house.
When should I move from outsourced accounting to an internal team?
Consider an internal hire when the business has enough daily finance work, operational complexity and management need to justify dedicated capacity. A hybrid model is also common: internal staff handle daily operations while an external firm handles reporting, tax or specialist work.
