S3 Group

S3 Group helps businesses turn complex commercial and operational problems into practical systems that work. Established in 2004 and led by Jonathan Chak, we bring more than 20 years of experience supporting over 500 businesses, from founders and owner-led SMEs to major organisations.

We combine business consulting, operations transformation, technology strategy, solution architecture and implementation. We uncover how work actually happens, clarify rules and exceptions, redesign workflows, and lead delivery across AI-enabled automation, custom platforms and ecommerce.

Our experience includes AI-enabled property arrears management implemented around existing core systems without adding administrative headcount; transformation of quotation, ecommerce and fulfilment, including WordPress-to-Shopify migration; and partner and customer platforms for Panasonic and McDonald's. The McDonald's promotion recorded 1.5 million registrations.

We also bring commercialisation experience spanning financial and ROI modelling, capital raising advisory and investor portals. Jonathan's founder and government-advisor background includes reviewing more than 500 MVP Grant applications.

Our strength is connecting commercial priorities with operational detail and technology execution, from discovery and solution design through implementation. Named testimonials on our website include Fuji Xerox Australia, Daikin Australia, Senstra and Deepmeds.
