The booksare the startof the conversation.
Most accountants close your books. We help you decide what to do next. Rengo brings accounting, tax, advisory, corporate services, and audit support together in one team, built for Singapore SMEs who want more than compliance.

- Built for SMEs that big firms ignore and small firms outgrow
- One team across accounting, tax, advisory, corporate services, and audit
- Transparent on price. First conversation is free
One firm. Four practices.
Accounting, tax, advisory, corporate services, and audit. Under one roof. The advice on one side is informed by the numbers on the other.
We talk strategy, not just statements.
Four things our clients say at the end of year one. Verbatim. Cleaned up only for brevity.
- 01
We talk strategy, not just statements.
Other firms hand you a P&L. We use it to tell you what to do next. Our consultants are operators first. They have helped SMEs decide, expand, pivot, and exit.
- 02
We have lived inside Singapore's regulatory landscape.
IRAS reviews, MOM applications, ACRA filings, GST disputes. We have handled them all. Not from a textbook. From the work.
- 03
One team. Not five vendors.
Strategy, audit, tax, books, payroll, work passes. Under one roof. The advice on one side is informed by the numbers on the other.
- 04
Transparent on price. Quoted before we start.
No teaser pricing. No surprise bills. Every engagement is scoped and quoted before a single hour is billed. You will know the cost of the work, the shape of what you are getting, and what falls outside the scope.

Other firms keep your books. We help you write the story your books should tell.
Bookkeeping firms hand you spreadsheets. Big firms quote you out of the room. Rengo sits in the middle. Modern, strategic, and grounded in real Singapore SME experience. The books are the start of the conversation, not the end of it.
Built for the SMEs that big firms ignore and small firms outgrow.
Names withheld out of professional discretion. Sectors and tenure as stated. Real engagements, real outcomes.
- Property DeveloperClient since 2018
“Property development in Singapore sits on top of one of the more complicated revenue recognition regimes out there. Build-to-order pre-launches, the SFRS 115 call between over-time and point-in-time, capitalised interest on construction loans. When our statutory auditor comes back with queries on any of it, Rengo is the firm we send those queries to. We have never had to bring a Big Four in for this.”
Finance Director - Engineering & MEP ContractorClient since 2012
“Government contracts come with their own quirks. GST on every variation order, retention sums, the audit trail through to project sign-off. Rengo has been our external tax and accounting advisor since 2012. They are the firm we call when the auditor or IRAS comes back with a question we cannot answer on our own.”
Group CFO - Interior Design & Renovation StudioClient since 2014
“Our financial year always closes with a stack of work-in-progress to be allocated correctly before the audited accounts can go out. Rengo is the firm that walks our auditor through it every year. Ten years in, January has stopped being the month we dread.”
Managing Director - Multinational F&B GroupClient since 2020
“Running across multiple outlets and an overseas arm means our group filing is never simple. FX translation, intercompany positions, GST across legal entities. We engaged Rengo at the group level for audit, tax, and the consolidation work that sits above the day-to-day, which is where it actually matters.”
