Institutional Trust, Human Warmth & Measurable Outcomes
Founded in Singapore in 2013, One Accounting Services Singapore Pte Ltd combines 12+ years of direct local operational practice with senior consultants possessing over 20 years of background in finance, taxation, and corporate governance.
A One-Stop Corporate Advisory Built for Modern Business
Operating from the iconic Golden Mile Tower along Beach Road, One Accounting Services Singapore was founded with a singular conviction: corporate administration, accounting, and compliance should never hold entrepreneurs back from growth.
Unlike impersonal multinational firms with rigid fee structures or understaffed sole practitioners, our 20-strong team functions as an agile extension of your company. We balance direct face-to-face consultations at our Beach Road headquarters with rapid, frictionless WhatsApp messaging and encrypted cloud accounting.
ACRA-Registered Filing Agent Status
Direct electronic integration with ACRA BizFile+ enables us to lodge company formations, annual returns, and share transfers with zero third-party delays.
IRAS Tax Master & SFRS Adherence
Our financial accountants continuously audit your ledgers against Singapore Financial Reporting Standards (SFRS) and latest IRAS corporate tax updates.
The 60%–70% Overhead Reduction Framework
Hiring full-time in-house bookkeepers in Singapore entails high fixed salaries, CPF contributions, software licenses, and management training. Outsourcing to OAS delivers superior compliance at a fraction of the cost.
Drastic Cost Savings
Eliminate in-house junior accountant wages (SGD $3,500–$5,000/mo) and employer CPF levies. Our retainers start from just $50/month with zero software markups.
Reclaim 15+ Hours Each Week
Founders spend up to 70% less time organizing receipts, reconciling bank lines, calculating CPF schedules, or answering ACRA inquiries.
Zero Statutory Penalties
Our automated compliance tracking guarantees you never miss an ECI, Form C-S, GST F5, or Annual Return filing deadline.
