The GST cash trap#

With Singapore's GST at 9 percent (as of 2024), a business collecting $50,000 in monthly revenue accumulates $4,500 in GST liability every month — $13,500 per quarter. Many SME owners treat this collected GST as part of their cash flow, spending it on operations. When the quarterly filing comes due, they face a sudden $13,500 outflow that can trigger overdrafts, delayed payments to suppliers, or even missed payroll.

How AskBiz tracks it#

Upload your invoicing data or accounting export. AskBiz calculates your accumulated GST liability as of today — output tax collected minus input tax credits on your purchases — and shows you exactly how much you should have in reserve. It updates this number as you add new invoices. Ask: 'How much GST do I owe this quarter so far?' and get an instant, accurate answer. No more surprises on filing day.

Real scenario: a renovation contractor in Jurong#

Wei Ming runs a renovation firm doing $120,000 per month in revenue. His quarterly GST remittance averaged $27,000 after input credits. Three times in two years, he had to take an emergency line of credit to cover the GST payment because he'd used the cash for materials purchases. After connecting AskBiz to his invoicing data, he set up a weekly check: 'What is my current GST reserve requirement?' The answer helped him move the exact amount into a separate account each week — $6,750 per week on average. He hasn't needed the emergency credit line since, saving $3,200 annually in interest charges.
