Senior advisory for owner-led businesses in Singapore.
Rengo sits between the Big Four firms that quote SMEs out of the room and the bookkeeping shops that hand them spreadsheets. Modern, strategic, and grounded in the real Singapore SME work that has been our practice for over four decades.

Four things we will not move on.
- 01
Strategy without numbers is hope.
Numbers without strategy is paperwork. We do both. That is the entire reason this firm exists.
- 02
SMEs deserve real advisory.
Not just compliance. Not just a Big Four budget quote that excludes them from the conversation.
- 03
Singapore's regulatory landscape rewards practitioners.
Not theorists. We have been in the rooms with IRAS, MOM, and ACRA. From the work, not the textbook.
- 04
You should not have to manage five vendors.
Accounting, tax, audit, corporate secretarial, payroll. One team, one mandate, one accountable senior contact.
Led by senior practitioners, built around the work.
Rengo (Private) Limited was established in 1981. Today its practice is led by Gillian Pok, our Principal Consultant and Managing Director.
Gillian holds a Master of Professional Accounting and is a Certified Practising Accountant (CPA Australia) and a Singapore Certified Management Consultant (CMC). Her career began inside a listed multinational, where she spent twelve years as Financial Controller responsible for the books of two manufacturing plants across Singapore and Malaysia, operating under SOX (Sarbanes-Oxley) controls and reporting monthly to senior management. In 2012 she moved into independent practice.
Across thirteen years of independent practice she has advised over two hundred Singapore SMEs on the financial structures, forecasting, internal controls, M&A, and tax-planning work that owner-led businesses rarely get from compliance-only firms. Our team brings together accounting, audit, tax, and management consulting expertise, anchored on senior practitioners with deep operating experience.

Four operating principles.
- 01
First conversation is free.
We figure out whether we are the right firm for you. If we are not, we will say so and point you somewhere better.
- 02
One named senior contact.
Not a help-desk queue. The person you meet is the person on the file.
- 03
Plain language.
We translate IRAS-speak, ACRA-speak, and finance-speak into decisions you can actually take.
- 04
Transparent on price.
Every engagement is scoped and quoted before any work begins, against a defined deliverable. No teaser pricing. No surprise mid-engagement bills. You will know the cost of the work, the shape of what you are getting, and what sits outside the scope.
Other firms keep your books. We help you write the story your books should tell.
Tell us what is on your mind.
Growth, books, audit, a tax letter you do not understand. We will tell you whether we are the right firm for you. First conversation is free.
