Answers

Common questions

How much does outsourced accounting cost in Singapore?

Most small companies pay S$300–1,500 a month depending on transaction volume, GST and payroll. Our plans start at S$350 a month, with a fixed quote after a free call.

Do you file GST F5 returns?

Yes. We reconcile input and output GST at 9% and prepare your GST F5 each quarter, ready for you to submit or for us to file with your authorisation.

Can you prepare XBRL and Form C-S?

Yes. We prepare your financial statements and XBRL for ACRA, and the ECI and Form C-S or Form C working papers for IRAS.

Is outsourcing cheaper than hiring an accountant?

Usually. A full-time accountant in Singapore costs S$4,000–6,000 a month with CPF; most SMEs need a fraction of that time.

Which software do you use?

Xero and QuickBooks Online most often; we can work in your existing software.
