TL;DR

  • Nothing matches a GPO on speed for common indirect categories, because it skips the sourcing cycle entirely rather than running it faster.
  • Una members save an average of 18 to 22%, with pricing access often live within 30 to 60 days and full onboarding inside 90.
  • Real member results back it up: 27 percent average across categories in weeks, 23 percent on shipping worth over $650,000 a year, and up to 15 percent on food costs.
  • Strategic sourcing, e-auctions, and supplier consolidation can all produce strong savings, but each runs its own months-long sourcing cycle first.
  • A deep strategic sourcing effort can match or beat a GPO's average in one specialized category, at the cost of months of internal resources.
  • Bottom line: a GPO isn't competing with the rest of the procurement toolkit. It frees up the time to use that toolkit properly on the categories that justify it.

Procurement has no shortage of proven levers for driving savings. Strategic sourcing, e-auctions, supplier consolidation, and deep category management maturity all have a track record of impressive results, and together, they make up the “craft” of procurement.

But can any of them beat a group purchasing organization (GPO) like Una on the two things that matter most when a business needs results: how fast the savings show up, and how large they are?

We’re obviously biased here, so we’ll do our best to avoid creating a rigged comparison. Each strategy has earned its place in a mature procurement function for good reason. 

The GPO Benchmark

Let’s start with the numbers we’re most proud of. At Una, our members save an average of 18 to 22% across core indirect categories, with onboarding fully complete within 90 days from first conversation to fully active membership, and discounted pricing often accessible within 30 to 60 days.

Real member results back that up. A behavioral health network with no formal procurement function saved an average of 27% across food, office supplies, uniforms, and JanSan, within weeks of connecting to contracts. One member saved 23% on shipping, worth more than $650,000 a year. A meal program operator serving over 150 locations cut food costs by up to 15% while keeping its existing local supplier relationships intact. A national YMCA purchasing network saved 10 to 15 percent on food costs alone across its full location base.

None of this required an RFP, a vendor evaluation cycle, or months of internal alignment. The contracts were already negotiated. Members simply connected to them.

The Contenders

  • Strategic sourcing and RFPs: Procurement's deepest, most tailored lever can produce savings that genuinely outperform a GPO average in a single category, especially one specific to the business. The tradeoff is time. A full RFP cycle, from issuing the request to signing a contract, typically runs several months per category, and that's before accounting for internal stakeholder alignment.
  • E-auctions. Once running, an e-auction compresses pricing fast, sometimes within a single event. But getting there requires upfront work: qualifying suppliers, finalizing specifications, and building a category profile detailed enough to run a fair auction. That prep work alone can take weeks before the actual savings event happens.
  • Supplier consolidation and renegotiation. Reducing supplier count and using consolidated volume as leverage produces real, durable savings. It depends on a clean spend analysis first, to see where the duplication and leverage sit, followed by negotiation cycles with each remaining supplier. It’s definitely a worthwhile exercise, but slow to execute properly.
  • Spend analysis and category management maturity. The other strategies on this list all depend on this one being done well first. Savings from a maturing category management function tend to show up over quarters, as strategy compounds, not within weeks of starting.

Strategic sourcing wins when a category is core to the business and worth the deeper, slower investment. E-auctions win when a category is already mature and well specified, and the only thing left to extract is price tension between qualified suppliers. Consolidation wins when the real problem is supplier sprawl rather than price itself.

What none of them do is beat a GPO on speed for common indirect categories, because none of them start from a contract that’s already negotiated. Every one of these strategies runs its own version of the sourcing cycle. A GPO skips it entirely.

The Verdict

For pure speed, nothing beats a group purchasing organization for the indirect categories it covers. Other strategies might source faster or better in specific circumstances, but we’re not comparing apples with apples here. A GPO membership means you aren’t doing the sourcing at all: it simply hands you the outcome of sourcing that’s already happened.

On savings percentage, the honest answer is more nuanced. A deep, well-run strategic sourcing effort can sometimes match or exceed a GPO's average in a single, highly specialized category, particularly one where customization and supplier relationship matter more than volume leverage. But getting there can tie up internal resources for months.

With that in mind, here’s the verdict: Use a GPO for speed and breadth across indirect spend, freeing the internal capacity to run strategic sourcing, e-auctions, and consolidation properly on the categories that justify that level of investment. A GPO shouldn’t compete with the rest of the toolkit. It can make using the toolkit affordable in terms of time, because every hour not spent negotiating office supplies or shipping is an hour available for the category that moves the business forward.
