TL;DR
- Delaying a GPO decision has a real cost: every month spent "getting to it next quarter" is a month of paying full retail on categories that could already be discounted.
- The math is simple: apply Una's average member savings of 18–22% across core indirect categories (office supplies, shipping, food service, JanSan) to your annual spend to get a monthly cost of delay.
- Real member examples show the gap adds up fast; one member's shipping savings alone were worth roughly $54,000 per month in delay.
- Una's onboarding is fast (discovery call, free cost analysis, contract connection), with no RFP, no lengthy evaluation, and no minimum commitment.
- Membership is free with no purchasing requirements or exclusivity; you keep full control over which contracts to use.
- Bottom line: run the math on your own spend, put a number next to "next quarter," and use that as the business case for your CPO/CFO then validate it with Una's free cost analysis.
Opportunity cost is the value you give up by choosing one option over another, even when that option was to do nothing. Delaying a decision to join a Group Purchasing Organization (GPO) carries this exact cost.
Here's how to calculate opportunity cost, so you can build the case for GPO membership to your CPO or CFO with a real number.
The Opportunity Cost Math
Most GPO conversations stall at “we'll get to it next quarter.” But every month that decision to join a GPO sits in the backlog, you're probably paying full retail on categories that could already be discounted, and that gap shows up on the P&L whether anyone's tracking it or not. What’s needed is a number to put next to that delay.
The math is simple enough to run in your head. Una members save an average of 18 to 22 percent across core indirect categories. Take your annual spend in office supplies, shipping, food service, and JanSan, apply that % range, and you have a rough monthly cost of doing nothing.
Monthly Cost of Delay For Core Indirect Categories
Here are a few real examples that make the size of that gap harder to ignore.
- One member's biggest headache was shipping. After a cost analysis against real contract terms, they landed on savings of 23 percent, which worked out to more than $650,000 a year. Break that down and every month of delay before signing was worth roughly $54,000 in shipping costs alone in a single category.
- A network of behavioral health centers had no formal procurement function and unmanaged spend across food, office supplies, uniforms, and JanSan. Within weeks of connecting to pre-negotiated contracts, they were saving an average of 27 percent across those categories combined. The delay cost here included full-price purchasing across four categories at once, multiplied by however long the decision had already been sitting on someone's desk.
- A national YMCA purchasing organization saw 10 to 15 percent savings on food costs alone, spread across a large network of locations. Yes, the cost of delay was relatively small on a single order, but it was substantial once multiplied across every location, every week, for as long as the decision waited.
Speed to Savings
What makes the delay especially costly is how little time the alternative takes. Una's onboarding runs on a speed-to-savings model: a discovery call, a free cost analysis against your real spend data, and a connection to relevant contracts, often complete within weeks. There's no RFP process, no lengthy vendor evaluation, no minimum commitment locking you in if it doesn't work out.
In other words, the gap between deciding and saving is short.
None of this requires disrupting how you currently buy. Membership is free, with no purchasing requirements or exclusivities, and you keep full control over which contracts to use. The only real cost is the one already showing up quietly in your indirect spend line every month you wait.
Run the math on your own spend. Multiply your indirect categories by even the low end of that 18 to 22 percent range, and put a number next to "next quarter." That number is the business case. Take it to your CPO or CFO, then talk to Una and see what a free cost analysis says the real figure looks like, with no obligation attached.
