Is your organization facing one of these questions?

  • What is the right solution and vendor for this purchase?
  • Are there areas where we can save money without losing quality?
  • Does our team have the skill and time to negotiate effectively?

Buying Excellence helps clients answer these questions and get the maximum benefit from their vendor expenses through RFP facilitation, competitive sourcing, negotiation support, and buyer training. The results are measurable and often dramatic:

  • “We are saving over seven figures every year on professional services because of Buying Excellence.”
    – Jim Harris, CFO of National Non-Profit
  • “Jack led us to 50% savings in an area where I thought our costs were in line.”
    – Jeff Martello, CEO of Construction Company
  • “Buying Excellence helped us decide that outsourcing was the right decision, then find best vendor.”
    – Jerry Dowless, CEO of Government Contractor
  • “As a direct result of our project, we reduced our cost 19% on our biggest expense, without changing vendors.”
    – Tom Freiling, CEO of Internet Retailer

Jack Quarles leads Buying Excellence clients through a structured process of defining value, increasing options, and then selecting the right solution. In many cases this involves a competitive sourcing process such as an RFP.
