CAS Accounting Management and Services is a Singapore-based accounting firm with more than 20 years of experience helping small and medium-sized enterprises, start-ups and self-employed professionals keep their finances in order. Operating from Primz Bizhub in Woodlands Close, the firm offers professional and affordable accounting and bookkeeping services designed to streamline financial operations, so owners can spend less time on compliance and more time growing their business.
Its core services span full-set bookkeeping on monthly, quarterly, bi-annual or annual cycles, compilation of financial statements in line with Singapore Financial Reporting Standards, and a complete GST suite covering voluntary and compulsory registration, quarterly GST F5 returns, Form F7 filings and responses to IRAS queries. On the tax side, CAS completes and submits corporate income tax returns, files Form C and C-S, prepares Estimated Chargeable Income submissions and handles personal tax computations for sole proprietors, the self-employed and partnerships.
Beyond bookkeeping and tax, the team manages payroll with monthly salary and CPF computation and year-end IR8A forms, company incorporation for sole proprietorships, partnerships and Pte Ltd entities, professional consultation on accounting practices and SOPs, XBRL preparation for ACRA filing, and corporate secretary services. All-in-one bundles scale from basic solutions for self-employed individuals to comprehensive packages for medium-sized businesses.
The firm's stated mission is to empower SMEs with Client-focused, Accurate and Steadfast accounting services, and long-standing clients — some of whom have relied on CAS for over a decade — describe prompt, professional service that takes the stress out of accounting deadlines and requirements.
CAS Accounting Management and Services operates from an office in Primz Bizhub along Woodlands Close, where for more than two decades it has quietly handled the ledgers, tax filings and payroll runs of businesses across Singapore. The firm positions itself as a third-party accounting partner for small and medium-sized enterprises, start-ups and self-employed professionals — clients who typically cannot justify an in-house finance team but still need their compliance handled accurately and on time.
The practice's name doubles as its mission statement: to empower SMEs with **C**lient-focused, **A**ccurate and **S**teadfast accounting services that reduce financial complexity. Its vision is to be the preferred third-party accounting service partner for SMEs in Singapore, and client testimonials — including customers who have stayed with the firm for over a decade — suggest it comes close to that goal.
What stands out is the breadth of industries behind that 20-year figure. CAS's client base spans construction and engineering, food and beverage, hair salons, wholesale, retail outlets, recycling, manufacturing, interior design, non-profit organisations, and various service and education industries. That variety matters in bookkeeping, where the quirks of each sector shape how the books should be kept.
Three promises anchor the service. First, timeliness: the firm states that your deadlines are its top priority and that it delivers accurate results, fast. Second, experience: its professionals bring a wealth of industry knowledge accumulated over two decades. Third, transparent pricing: affordable, all-inclusive fees with no hidden costs.
The core offering is bookkeeping and GST. CAS maintains full sets of accounting entries on monthly, quarterly, bi-annual or annual cycles, compiles management reports — balance sheets, profit and loss statements, trial balances, general ledgers — and sets up cloud or desktop accounting software. At year end, the team compiles financial statements in compliance with Singapore Financial Reporting Standards, reviews year-end transactions and adjustments, and liaises with auditors. On the GST side, it handles voluntary and compulsory registration and deregistration, quarterly GST F5 returns, Form F7 filings and IRAS queries.
Corporate tax is the second pillar. The firm completes and submits corporate income tax returns, files Form C and C-S, prepares Estimated Chargeable Income submissions, and computes personal tax for sole proprietors, the self-employed and partnerships. It also helps structure investments and business transactions around local incentives such as group relief and allowable deductions to minimise tax liabilities.
A third service stream covers back-office essentials: payroll with monthly salary and CPF computation and year-end IR8A forms; company incorporation for sole proprietorships, partnerships and Pte Ltd entities; professional consultation on developing and enhancing accounting practices and SOPs in line with GAAP; financial statements in full or partial XBRL format for ACRA filing; and corporate secretary services.
CAS packages its work into four all-in-one bundles: Basic Solutions for self-employed individuals and LLPs with low transaction volumes, New Business for start-ups needing compliance and foundational management, Small Business for growing teams, and Medium Business for high-volume operations seeking robust, comprehensive support. Every bookkeeping bundle includes account code system setup, transaction recording, multi-currency and GST transactions, journal entries, payables and receivables, bank reconciliation and monthly management reports. Clients who take a QuickBooks Online package alongside monthly bookkeeping receive an additional 5% discount each month.
Enquiries go through the website's form, by phone or WhatsApp at +65 9724 4218, or by email at contact@casaccountingsg.com. Clients describe prompt, responsible service with no delays — the kind of steady back-office presence that lets owners stop worrying about filing deadlines and get back to running the business itself.
