About William Wu

Principal - Cost Control

William has a long track record serving clients, having spent over 25 years in various advisory roles in the energy, manufacturing, technology, healthcare, construction, property management, non-profit, and any service-related industries.  William’s career started in public accounting at Arthur Andersen where he then transitioned to technology consulting with Price Waterhouse implementing global ERP solutions.  Prior to Optimal Profit Solutions, he was a founding shareholder at Rand Group, where he helped the company become one of the larger Microsoft resellers in North America for the emerging and middle market.  Throughout his work history, he has always readily relied on business data to help drive business decisions.  This led him to launch Optimal Profit Solutions, with a focus on expense reduction for his clients by analyzing organizational spend and identifying cost optimization opportunities. This can be strategic through cost control and supplier management, or tactical by identifying better pricing or renegotiating existing terms.  With his background, he can also help clients determine where to best invest their technology dollars to achieve the highest returns and to ensure clients do not overpay for those IT investments.

William offers clients a no risk value proposition to maximize EBITDA by reducing prices paid for goods and services.  Optimal Profit Solutions has expert analysts monitoring market prices in over 50 different expense categories across North America and uses that data to help clients secure better rates.  Optimal Profit Solutions can perform a spend assessment for the entire organization or a deep dive analysis on just a single specific expense area.
