HONEST COMPARISON · UPDATED AUGUST 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 accounts are handled by a named ISCA practitioner at a flat fee instead of a platform with expense-banded pricing.
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 ISCA member firm, established 2013: a named practitioner does the work, the fee is flat and published, and you can bill monthly. 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$90/mo (S$79/mo billed annually) |
| Mid plan | Accounting Essentials — from S$90/mo | Growth — S$280/mo (S$250/mo billed annually) |
| Top plan | Accounting Premium — from S$250/mo | Established — S$650/mo (S$580/mo billed annually) |
| 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, or annually at a discount — both published |
| Who does the work | Assigned accountant on a platform team | The named ISCA practitioner on our About page |

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 named person who knows your file
Your accounts are handled by the ISCA practitioner named on our About page — not routed through a support queue. Questions get answered by someone who has seen your numbers before, on WhatsApp, phone or email.
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 monthly billing and a published price
Every tier is on the website with a monthly option. No annual lock-in required to get the advertised rate, and no quote call before you see a number.
Essentials
For dormant or small companies and early-stage startups.
Growth
For growing SMEs that need tax, GST, and payroll handled.
Established
For established businesses wanting advisory and dedicated support.
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 ISCA practitioner handles your file at a flat published 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$90, S$280 and S$650 per month (S$79, S$250 and S$580 when billed annually), priced on workload rather than expense bands, with monthly billing available. At the smallest expense band Sleek's entry plan is cheaper; the models diverge as your volumes grow.
Does Sleek lock you into annual billing?
Sleek's published accounting prices are billed annually per financial year. Synergy offers both monthly and annual billing, with the annual option discounted — the monthly price is the published price, not a premium.
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.
