Why I stopped buying on unit price (and started tracking total cost of care)

It started with a stack of old catheters

I walked into our supply closet one Tuesday in March 2024 to do my quarterly inventory check. What I found wasn't pretty—a whole shelf of Coloplast catheters that had expired six months earlier. Fifteen boxes. $2,400 worth, sitting there because our clinical team kept ordering more than they needed, and nobody was rotating stock.

I'm the procurement manager for a 40-person outpatient urology clinic. We spend about $180,000 annually on medical supplies—catheters, wound care, continence products—and I've been tracking every invoice for six years now. So when I saw that waste, something clicked. I wasn't just overpaying on unit prices. I was bleeding money on stuff we never used.

The moment I realized unit price is a trap

For years, I compared vendor quotes by unit price. Vendor A: $4.50 per catheter. Vendor B: $3.95. Easy choice, right? That's what I thought too. Until I started tracking total cost per patient episode.

Here's what I found: the cheap catheters had a higher failure rate. Patients would come back for re-insertions, using two or three catheters per visit instead of one. The product itself cost less, but the waste—and the staff time—added up fast.

I remember thinking, "The numbers said go with Vendor B. My gut said stick with Vendor A. Something felt off about the responsiveness of Vendor B's reps." Turns out, that slow response was a preview of reliability issues I hadn't accounted for.

What I learned from tracking 200+ orders over 6 years

After analyzing our spending patterns, I noticed a few things that changed how I buy everything now—not just catheters, but also things like hospital beds, surgical lights, and even patient education materials like what is a biosensor handouts.

• Setup fees eat your lunch. One vendor charged $75 per color for offset printing on our patient instruction sheets. That 'free' die cut? Not free. We paid $175 in hidden setup costs on a $400 order.
• Rush fees are a behavioral tax. When we needed a coloplast self catheterization video printed on a brochure insert for a patient education event, the rush charge was 60% above standard. Three days earlier planning would've saved us $240.
• Small orders pay the same setup. A $200 order of custom-printed supplies costs the same setup as a $2,000 order. So every time we split a bulk order into multiple small ones, we doubled the setup cost.

The turning point: when I compared TCO across 8 vendors

In Q2 2023, I did a full cost comparison for our catheter supply contract. Eight vendors over three months. I built a spreadsheet with columns for unit price, setup fees, shipping (which varied wildly), rush charges, and—this was the key—estimated waste rate based on product returns and complaints.

The cheapest vendor by unit price was actually the most expensive by TCO: $52,000 annually vs. $44,800 for a mid-priced vendor with better reliability. That's $7,200 a year—enough to fund a part-time clinical educator.

That's when the Coloplast catheters how to use training program we offered to patients became a major factor. The vendor that included patient education materials and video guides (like their self-catheterization video) saw lower waste rates because patients were using the product correctly. That's not something you see on a quote.

Small orders, big potential

I'll be honest: when I first started in this role, I thought small orders were a hassle. A $200 order of printed coloplast self catheterization video booklets? Not worth the paperwork, I thought. But here's what I've learned: the vendors who treated my small orders as seriously as my large ones—they're the ones I trust now with our biggest contracts.

I remember one vendor said to me, "We don't do quotes for orders under $500." I never called them again. A few months later, I placed a $15,000 quarterly order with a competitor who had answered my tiny $180 request within an hour.

That's the thing about being a small customer: you're looking for partners, not order-takers. And partners don't discriminate by order size.

Bottom line: cost isn't just the price tag

After six years of tracking every invoice, I've come to believe that total cost of ownership is the only metric that matters. And that includes the cost of hidden fees, waste, and missed opportunities from poor vendor relationships.

So the next time you're comparing quotes, don't just look at unit price. Ask about setup fees. Ask about rush charges. Ask about return policies and defect rates. And if a vendor doesn't want your small order today, remember: today's $200 order is tomorrow's $20,000 contract.

(Oh, and one more thing: I built a cost calculator spreadsheet after getting burned on hidden fees twice. It's saved us about $8,400 annually. Mental note: I should share that template.)
