Group Purchasing Partner Resources

Group purchasing enables organizations to combine their spending in a particular category (such as office supplies, power and energy, or maintenance services) and use that larger volume to negotiate lower prices and preferable terms with product and service providers.

Power & Energy

CJP has selected two power and energy providers that help organizations save money by aggregating demand and using that larger demand to negotiate preferential pricing with suppliers.

PowerOptions is a woman-run nonprofit that exclusively serves nonprofits. To explore opportunities with PowerOptions, please contact Derek Howell.

Best Practice Energy is a for-profit provider serving both for-profit and nonprofit organizations. To start the conversation with Best Practice Energy, please contact Jordan Berman.

We recommend that interested organizations contact both providers to learn how they can help save money and/or set fixed pricing for a specified period.

Visit our Power and Energy page for more information and updates.

Why group purchasing?

In addition to saving money, group purchasing can:

  • Save your organization both time and effort by eliminating the need to negotiate terms or shop around to compare prices
  • Eliminate budget uncertainties by fixing some prices for a given time period
  • Give smaller organizations access to services or pricing generally only available to larger organizations

How did CJP choose these preferred vendors?

In July 2020, CJP formed a Group Purchasing Pilot steering committee of leaders from 10 partner organizations to explore how to better use the collective size of our ecosystem of organizations to provide added value to our partners. The pilot committee focused on group purchasing and zeroed in on two initial categories — office supplies and power and energy. The participation of partners in the pilot initiative was critical and we were fortunate to have committee members with deep purchasing and procurement expertise. In the search for preferred providers, the pilot committee prioritized vendors that could provide excellent discounts and preferred terms, strong customer service, and a commitment to expanding and deepening the relationship in the years to come. The effort now continues through the Community Collaborations offerings that are part of CJP’s Partnerships and Services work.

Please contact Kimberlee Schumacher with any questions about group purchasing or suggestions of new categories of purchasing.
