The Around the World programme offers trips for two people with opening bids starting significantly lower than the usual retail price.
Travellers can bid for incentive travel packages with five- to seven-day itineraries in 14 worldwide destinations including Asia, Europe, and the US.
The money raised will go towards education and research in the motivational events industry.
Kurt Paben, Site International Foundation president, said: "What makes this opportunity unique is that bidding is open to everyone, not just Site members.
"These experiences offer the same top-notch accommodations that are offered through motivational travel incentive programmes. Our members and partners believe in the power of rewarding workplace performance and want to help educate the public of that value."
Incentive trips, meetings and events account for 15% of all travel spending, which creates 2.4 million jobs, £144bn in spending and £23bn in tax revenue, according to the US Travel Association.
