Q: What is group purchasing and how does a group purchasing organization work?

A: Group Purchasing Organizations create and manage contracts for indirect services and goods, and direct materials and commodities that are mutually beneficial to both the GPO suppliers and members.

To do this, GPOs first create a membership base that's comprised of companies looking to channel their spend using the GPO's agreements. The combined spend of these member companies creates leverage. It's this leverage that continues to attract GPO supplier partners and motivates them to offer their best pricing and service levels to GPO members.

As spend increases, a GPO can continue to strategically source more agreements with suppliers that have the ability to provide better pricing and agreements than GPO members could achieve on their own. GPO suppliers will actually forgo margin opportunities because their involvement in a GPO will greatly reduce the amount of money they need to spend acquiring new business.

At the end of the day, members rely on GPOs to help solve their procurement and sourcing concerns and suppliers rely on GPOs to build strong buyer relationships with a diverse portfolio of companies from many industries.

GPO membership ultimately allows both parties to save time, money, resources and simplify the buying process so they can concentrate on the projects that are most important to their respective companies and bottom lines.

Q: What does GPO mean and how does a GPO add value?

A: A GPO is a Group Purchasing Organization. As Group Purchasing Organization members continue to use GPO contracts – that are being constantly managed by the GPO – value increases for both members and suppliers.

More member spend means more spend flowing through agreements, which allows GPOs to negotiate even deeper discounts and continue to improve terms and conditions with suppliers. And as these supplier relationships mature, a GPO can likely further mitigate risk by engaging multiple people at various levels throughout supplier organizations.

While it's true that this level of engagement saves all GPO participants money, time and resources, a GPO goes beyond those impressive benefits to produce sustainable value. This is because even if savings diminish over time, a GPO will be constantly looking for new ways to enhance agreements and supplier performance.

Suppliers who engage at this deeper level will also see sustainable value. The large, diverse portfolio of members they get access to, the long-term relationships they build, the collaborative engagement they see and the in-depth industry knowledge they receive will continue to pay dividends.

What is a buying group?

A buying group is another term often used for a Group Purchasing Organization or GPO. A buying group or Group Purchasing Organization uses the buying power of a group of organizations to create cost savings and value-driven pricing for members, in addition to better terms & conditions.  

Q: What industries do GPOs operate in?

A: GPOs can operate in countless industries. However, they've been found to be extremely effective in many core industries, including:

  • Industrial manufacturing
  • Retail
  • Hospitality
  • Foodservice
  • Electrical
  • Plumbing
  • Non-profits
  • Education
  • Government

What enables GPOs to thrive in these sectors is the sheer number of companies that occupy the space. By combining the spend of these companies, both the members' buying power and the suppliers' market share become greater.

Q: How do I choose a GPO?

A: Because all GPOs provide access to leveraged agreements, the level of contract management is the differentiator. An advanced GPO manages the lifecycle of supplier contracts by:

  • Monitoring changing buying patterns in the market
  • Continually seeking opportunities for improvement and potential savings
  • Ensuring that the terms of the contract are being followed
  • Reviewing and auditing price files
  • Implementing a thorough supplier relationship management program

These activities require an extensive time investment when performed correctly, and being part of a GPO removes that time expenditure from member companies.

Additionally, the most sophisticated GPOs have partner-based relationships with their suppliers that focus on the total value of the contract instead of simply offering the lowest price.

Q: Do GPOs only cover standard “Off-the-Shelf” categories and products?

A: The OMNIA Partners GPO contract portfolio does include these types of products, but we also cover many core spend categories as well, including direct and indirect materials, value-added services like IT & telecom, human resources and much more. Our portfolio of GPO solutions continuously evolves to ensure an array of non-standard categories are always available to our members.

Q: Does a GPO take the place of my company’s purchasing department?

A: OMNIA Partners will become an extension of your procurement team, not a substitution. Strategic Sourcing is still done in-house by your company and OMNIA Partners does not in any way assume the role of the purchasing department. We serve as an additional resource for sourcing teams to increase productivity and efficiency. By joining a GPO, a company’s procurement function actually expands its scope of control, as well as enhances its strategic relevance to the organization.

“We can take advantage of what OMNIA Partners has already negotiated so we can focus on areas where we don’t currently have a presence. It’s taking our small team and growing it to a large team.”

- Paul Stasco, Senior Director of Corporate Supply Chain, Curtiss-Wright

Q: What if we can realize greater savings on our own for certain categories?

A: This question illustrates an important advantage of OMNIA Partners. In the engagement process, new members determine which pre-negotiated agreements they want to participate in. There's no requirement or obligation for a member to partake in any given agreement. However, OMNIA Partners is a resource that creates value for its members in numerous ways aside from savings.

Q: Does joining a GPO mean I can only purchase from suppliers in the group?

A: Members of OMNIA Partners always have complete autonomy to purchase from any supplier they choose. There's no obligation and no minimum. Members have the choice to opt in or opt out of each pre-negotiated supplier offering. This motivates suppliers to create attractive programs to provide additional value. Members can leverage category offerings and other resources based on their unique needs and where they find the most value can be driven.

Q: Our business is unique – can a GPO still benefit us and our specific requirements?

A: OMNIA Partners operates within a flexible framework that allows members to enjoy all the benefits of group leverage while retaining the ability to negotiate adjustments and incorporate options that address specific needs. Our members participate in structuring our supplier agreements so that we can create options best suited for their goals, no matter how unique those goals may be.

Q: My purchasing department is tasked with finding the best solutions for our organization all while saving money. How can a GPO help?

A: By joining OMNIA Partners, your company will be bypassing time-consuming RFP and sourcing procedures while gaining the flexibility to impact other areas of spend so that you can focus on more strategic initiatives. We also help create change management timelines and implementation plans to improve performance and to help you achieve savings faster and maintain continuous program compliance. Because we shoulder so much of the process, OMNIA Partners saves you a substantial amount of time and headaches in the end.

Q: How can I implement a GPO strategy for my organization?

A: After filling out a short GPO membership form, OMNIA Partners will help analyze your current spend to locate areas where we can enhance your current procurement strategies. Then we’ll assist in any change management efforts, which will be followed by continuous supplier management and market checks. Joining is free, the process is easy and we do all the heavy lifting for you and your company.

Q: What is a GPO Contract and what are the benefits of a GPO contract versus going out for bid/submitting an RFP?

A: GPO Contracts are pre-negotiated or pre-leveraged contracts with supplier partners that create cost savings for strategic spending. GPO contracts are:

  • Vetted by similar organizations for a common goal
  • Act as an extension of the organization to manage categories in the best interest of their members
  • Allow for configuration to support unique requirements
  • Have terms and conditions to stay within market pricing throughout the duration of the agreement

Q: How is a GPO Funded?

A: Typically, a GPO is funded via membership fees, administrative fees or some combination of the two. A membership fee can be a one-time payment that's paid upon joining the GPO. Alternately, the membership fee can be structured as an annual dues-based payment. In some cases, GPOs waive membership fees if a member participates in a certain number of agreements or surpasses a spend threshold.

Suppliers always pay GPOs administrative fees. Regardless of whether the fee is a flat rate or based on the amount of spend passing through the agreement, a GPO's funding structure is always transparent to its members. For example, OMNIA Partners does not require a membership fee, minimum order or spend obligation in order to join the collective membership and benefit from the leverage.
