ST Accounting & Consultancy (STAC) is a Singapore-based firm providing company incorporation, corporate secretarial, accounting, bookkeeping, tax and GST services to startups, small business owners and small-medium enterprises. Its main office is at 203 Henderson Road, Level 05-01, Henderson Industrial Park, and the firm also has a presence near North Buona Vista. Enquiries can be made via the website's free consultation channel or by email.
The firm positions itself as a one-stop, in-house back office for growing companies. Everything from taxation to GST to audit work, STAC says, starts with good bookkeeping and accounting — so its services span the full corporate lifecycle: incorporation with business and Corppass registration, company secretarial work including AGMs and ACRA annual returns, monthly/quarterly/annual bookkeeping, compilation of financial statements and unaudited reports, XBRL filing via BizFinx, financial ratio analysis, cash flow management and budgeting, income tax filing and GST submission to IRAS.
Work is carried out by certified professionals and closely supervised by a member of the Institute of Singapore Chartered Accountants (ISCA) and the Association of Chartered Certified Accountants (ACCA), with ongoing professional education recognised by both bodies. STAC is also a QuickBooks Online ProAdviser and helps businesses move to cloud accounting, leveraging technology for cost efficiencies it passes on to clients. Service is backed by a 14-day money-back guarantee (after deducting fees payable to ACRA), and the firm shares updates and promotions through a free newsletter.
ST Accounting & Consultancy — usually shortened to STAC — is a Singapore-based accounting and corporate services firm built on a simple conviction: business owners should spend their time growing the business, not wrestling with ledgers, filings and tax deadlines. From its main office at 203 Henderson Road, Level 05-01, Henderson Industrial Park, with a presence near North Buona Vista as well, the firm supports startups, small business owners and small and medium-sized enterprises across the full span of back-office work.
The firm's own material puts it plainly: everything from taxation to GST to audit work starts with good bookkeeping and accounting. Without detailed records, companies cannot make wise decisions when it is time to grow. That belief is why STAC positions itself as a one-stop, in-house solution — a team of professional accountants managing the numbers so founders and SME owners can focus on the business itself, while saving the time and cost of recruiting and training an in-house finance function.
STAC's service list covers the corporate lifecycle from day one. New companies can engage the firm for incorporation, which includes business registration and Corppass registration. Once a company is up and running, the corporate secretarial team handles the ongoing statutory rhythm — statutory updates with ACRA, annual general meetings, circulation of financial reports and filing of annual returns — along with ad-hoc resolutions when special situations arise.
The accounting side is deliberately flexible. Bookkeeping can be taken monthly, quarterly or annually depending on transaction volume, and the same records feed into compiled financial statements: income statements, balance sheets, statements of owner's equity and cash flow statements, together with unaudited annual reports for companies that qualify for audit exemption under ACRA's small company concept. Where ACRA requires financial statements in structured form, STAC handles XBRL filing through the BizFinx filing system.
Beyond compliance, the firm offers analysis that turns records into decisions: financial ratio analysis covering profitability, liquidity, solvency and business efficiency, plus cash flow management and budget and forecast work. On the revenue side, income tax filing covers preparation of the tax Form C/S and review of financial statements, while GST services handle monthly or quarterly submissions to IRAS.
STAC is candid about credentials, and that matters in this field. The team consists of highly experienced, certified professionals who are familiar with Singapore's regulations, procedures and policies, and all work is closely supervised by a member of the Institute of Singapore Chartered Accountants (ISCA) and the Association of Chartered Certified Accountants (ACCA). As Chartered Accountants, the team maintains professional competence through Continuing Professional Education recognised by ISCA and ACCA.
The firm also has a clear view of what makes a good bookkeeper: someone who takes the initiative to understand the business process, asks sensible questions rather than guessing, and stays technology-savvy as the industry modernises. Clients' work, STAC says, is done according to plans and on schedule by a team with a can-do attitude.
Technology is central to how STAC keeps service affordable. The firm is a QuickBooks Online ProAdviser and helps businesses set up and transform their operations with cloud solutions — online accounting software that lets owners access the same data over the internet, with records easily retrieved wherever they are. By leveraging technology to achieve significant cost efficiencies, the firm says those savings are passed on to clients, keeping pricing reasonable without compromising quality or timeliness.
Engagement is deliberately low-friction. Prospective clients can book a free consultation through the website, browse the published fee schedule, and sign up for a free newsletter carrying updates and promotions. As a service commitment, STAC backs its work with a 14-day money-back guarantee (after deducting fees payable to ACRA). For startups and SME owners in Singapore who would rather grow the business than chase receipts, STAC presents a tidy proposition: hand the back office to certified professionals and keep your eyes on the road ahead.
