HONEST COMPARISON · UPDATED SEPTEMBER 2026
Looking for a Sleek alternative in Singapore?
Sleek is a good platform — this page is not here to tell you otherwise. It is here to show you, with both firms' published prices side by side, what changes when your whole finance function is run by AI agents under a named accountant, at a fixed monthly fee, instead of on a platform with expense-banded pricing. Ours costs more; here is what it buys.
THE SHORT VERSION
Two different models, both legitimate.
Sleek is a venture-backed platform: one dashboard for incorporation, secretarial work, banking and accounting, priced by your annual-expense band and billed annually. Synergy Accounting is an owner-led Singapore practice, established 2013, whose Principal Accountant has been in practice since 2008, that now runs its clients' books with AI agents under a named accountant's review, at a fixed monthly fee. Neither model is wrong — they suit different businesses, and the honest job of this page is to help you work out which one is yours.
SIDE-BY-SIDE
Published pricing, compared.
| Sleek | Synergy Accounting | |
|---|---|---|
| Entry plan | Annual Filing & Bookkeeping — from S$68/mo | Essentials — S$490/mo, monthly bookkeeping with a named accountant |
| Mid plan | Accounting Essentials — from S$90/mo | Growth — S$1,190/mo, monthly accounts, GST, payroll and a review call |
| Top plan | Accounting Premium — from S$250/mo | Fractional Finance Team — S$2,490/mo, adds cash-flow forecasting and CFO advisory |
| What moves the price | Your annual-expense band — six bands from under S$30,000 to S$900,000 and above | The work itself — transaction volume, payroll headcount, GST and reporting frequency |
| Billing | Billed annually per financial year | Monthly at the published price, or annually at 20% off — both published |
| Who does the work | Assigned accountant on a platform team | AI agents do the volume work; the named accountant on our About page reviews and signs off |

WHERE SLEEK FITS
When Sleek is probably the better choice.
You want one platform for everything
Sleek bundles incorporation, corporate secretary, a registered address with a digital mailroom, business banking, nominee director and Employment Pass support alongside accounting. If you want a single vendor for the whole company stack, that breadth is genuinely useful.
You are software-first
Sleek's own accounting software, e-signatures and app-based workflow suit founders who prefer to manage everything in a dashboard and rarely need to talk to a person.
You are incorporating from overseas
Nominee director and visa support matter most to foreign founders setting up in Singapore — a use case Sleek serves directly and we do not.
WHERE WE FIT
When Synergy is probably the better choice.
You want a finance function, not a filing service
Every package includes monthly bookkeeping run by AI agents and reviewed by the named accountant on our About page; Growth adds monthly management accounts, GST, payroll and a review call. That is a different scope from an annual-filing plan, and the price reflects it.
You want a fee that does not step up with your revenue
Our packages are priced on the work — transactions, payroll, GST, reporting — not on how much you earn or spend. Growing revenue with the same workload does not move you into a higher band.
You want a person who knows your file
Questions go to the accountant who reviewed your numbers, on WhatsApp, phone or email — not a support queue. Nothing is filed with IRAS or ACRA without her sign-off and your approval.
Essentials
For smaller SMEs that need their books and filings handled properly.
Growth
Your full finance function for a growing team.
Fractional Finance Team
Senior finance leadership, on demand.
SWITCHING
Already with Sleek? Switching is simpler than it looks.
Moving accountants in Singapore is a routine handover, not a renovation: collect your ledgers, financial statements and filing access, appoint the new firm, and time the cut-over around your financial year end where you can. We wrote a step-by-step guide to doing it cleanly — including the handover file to request and the questions to ask before you commit to anyone, us included.
Common questions.
Is Sleek a good accounting provider in Singapore?
Yes — Sleek is an established, well-funded platform serving thousands of Singapore companies, and its incorporation-to-accounting bundle is genuinely convenient. The comparison is not about quality but about model: a software platform with banded pricing and a support team, versus an owner-led firm where a named accountant handles your file at a fixed monthly fee.
How does Sleek's pricing compare with Synergy Accounting's?
Sleek advertises accounting from S$68/mo (Annual Filing & Bookkeeping), S$90/mo (Accounting Essentials) and S$250/mo (Accounting Premium), with the final price set by your annual-expense band and billed annually per financial year. Synergy's packages are S$490, S$1,190 and S$2,490 per month, billed monthly and priced on workload. Ours cost more: they buy monthly bookkeeping by AI agents, a named accountant reviewing and signing off, and — from Growth — monthly management accounts, GST, payroll and a review call. If you need an annual filing done cheaply, Sleek's entry plan is the better fit; if you need your finance function run every month, compare like with like.
Does Sleek lock you into annual billing?
Sleek's published accounting prices are billed annually per financial year. Synergy bills monthly at the published price, with no annual commitment required; if you prefer to pay for the year upfront, the annual rate is 20% lower.
How do I switch from Sleek to another accountant?
Switching accountants in Singapore is routine: appoint the new firm, hand over your ledgers, financial statements and IRAS/ACRA access, and time the change around your financial year end where possible. Our step-by-step handover guide covers the documents to collect and the questions to ask before you move.
Can Synergy take over mid-year from Sleek?
Yes. We review the state of your books first, quote any catch-up bookkeeping as a one-off, and take over the compliance calendar from the next filing. Nothing needs to wait for a new financial year, though a year-end handover is cleanest.
