I'm the Guy Who Signs the PO: Why Your Small ResMed Order Deserves (and Gets) My Full Attention

Small Orders Aren't Small to Me

I'm a procurement manager at a mid-sized healthcare group. I've managed our medical equipment budget — roughly $180,000 annually — for six years. I've negotiated with 30+ vendors, tracked every single invoice, and I can tell you: the vendor who treats a $200 order like it matters is the vendor I trust with a $20,000 contract.

Let's get this straight. I'm not talking about the big capital purchases — the hospital beds, the anesthesia machines. Those get attention by default. I'm talking about the stuff that keeps those machines running: the ResMed AirSense 10 power supply replacement, the patient monitor cables, the specific anesthesia machine components that no one thinks about until they fail.

Here's the reality that gets oversimplified: when I'm sourcing a replacement power supply for an AirSense 10, I'm not just buying a part. I'm testing a vendor. How quickly do they respond? Do they stock the exact model I need? Is the pricing transparent? (Ugh, hidden fees are my pet peeve.) That small order is a trial run. And if you treat it like an afterthought, you've failed the test.

The Dollar Logic: Why 'Small' Can Be a Smart Investment

Total Cost of Ownership (TCO) Over Unit Price

It's tempting to think you can just compare unit prices for a CPAP power supply. But look closely. I almost went with Vendor B on a $45 power supply quote — until I calculated the TCO. Their 'low' price excluded the specific adapter needed for our older AirSense 10 model. That was another $18, plus a $12 'hazardous materials' shipping fee for the lithium battery component. Total: $75. Vendor A quoted $62, all-in. A 17% difference hidden in the fine print.

That's why I track this stuff. In Q2 2024, I audited our spending on 'small' replacement parts. I found that 28% of our budget overruns on those items came from exactly this: incomplete quotes on components like power supplies and monitor cables. We implemented a policy requiring itemized breakdowns for any order over $100. Overruns dropped by 40% in the following quarter.

The Vendor Relationship is the Real Asset

When I was starting out in procurement, I made a mistake. I chased the absolute lowest price for a batch of patient monitor leads. The vendor? A nightmare to deal with. Wrong specs shipped twice. No responsiveness on returns. That 'cheap' option resulted in a $1,200 redo when we had to rush-order the correct parts from a more reliable source.

I still kick myself for that. If I'd spent a few more dollars and built a relationship with a vendor who cared about the order — even a small one — I'd have saved hours of my time and actual money. The goodwill I'm working with now on our major equipment contracts took three years to develop. It started with a $250 order for CPAP masks.

Future Proofing: The Big Potential of Small Clients

The vendors who treated my $200 order for an AirSense 11 power supply with respect? They're on my shortlist for our next capital equipment purchase. Because I learned something: their service level is consistent regardless of order size.

When a vendor tells me 'sorry, our minimum is $500 for that component,' I'm not offended. I understand logistics. But if they tell me, 'we can do that, but the setup fee means you'll pay more per unit' — and they explain it clearly — that's a green flag. They're not hiding costs. They're being transparent. Contrast that with the vendor who accepts the order but ships it three weeks late because 'it's a small item, it wasn't a priority.' That vendor lost my future business.

What About the 'Cost of Service' Argument?

I get it. Some vendors will argue that processing a small order has the same overhead as a large one. True. But here's the thing: that overhead is the cost of acquiring future revenue.

Look, I'm not asking for a discount on my 50-unit order of anesthesia components because I placed a trial order first. I'm asking for competent, timely, transparent service on the trial order. (Mental note: I really should formalize a vendor evaluation scorecard based on small-order performance.)

The 'cheap' vendor who dismisses my small order isn't saving money. They're losing a potential $20,000 annual account. The 'premium' vendor who treats it with care is making an investment in a relationship.

My Bottom Line: Fairness Isn't About Size

I've spent six years analyzing over $180,000 in cumulative supply costs. My conclusion is simple: the vendors who win my long-term loyalty are the ones who treat every order — no matter the dollar value — as a test they need to pass.

When I say 'small doesn't mean unimportant,' I am not being naive. I'm being strategic. The next time a clinician needs a ResMed power supply replacement at 4 PM on a Friday, or a specific anesthesia machine component for a scheduled surgery, I'm calling the vendor who already proved they can handle it. Not the one who ignored my first call because it was 'just a small order.'
