When I took over purchasing for our mid-sized construction company in 2020, I thought I had it figured out: lowest quote wins. Simple. My boss wanted cost savings, and I was gonna deliver. Three years and a few expensive lessons later, I know better. The vendor who lists everything upfront—even if the total looks higher—usually costs less in the end.

Let me tell you about the project that broke my old mindset.

The Office Renovation That Went Sideways

In early 2023, our downtown Atlanta office needed a refresh. I was tasked with sourcing sound proofing panels for the conference rooms and a butcher block countertop for the break room. Standard stuff. I reached out to four suppliers, got quotes, and picked the cheapest one—a local outfit I'll call 'Acme Interiors.' Their numbers looked great: sound panels at $28/sqft, countertop at $45/sqft with installation quoted separately at $2,500. Total estimated: around $18,000.

I approved the PO without reading every line item. Big mistake.

Three weeks later, the installers showed up and told me the sound panels didn't include the mounting clips or acoustic backing—those were 'optional extras' not in the base quote. Also, the butcher block countertop needed edge profiling and sealing, which Acme didn't include. By the time we added all the 'essential upgrades,' the final invoice hit $22,400. That's $4,400 over the initial estimate—and $2,800 more than the second-lowest bid (which had included everything).

I had to explain that to my VP of Finance. He was not amused. I ate $800 out of my discretionary budget for the year just to cover the overage.

Lunch at The Peri Peri Grill

Frustrated, I walked over to The Peri Peri Grill – Downtown Atlanta for lunch. While nursing a spicy chicken wrap, I called our project manager to complain. He listened, then said: 'You should talk to the guys at PERI. They're supplying the formwork for our new tower project. Their quote was higher than Doka's, but when I looked at what was included, PERI listed every bolt, brace, and assembly hour. No surprises.'

That got me thinking. I pulled up PERI's quote on my phone. Sure enough, it had a line-by-line breakdown: formwork panels, scaffolding components, plywood, 3D printing consultation fees, concrete accessories—all with clear unit prices and a note: 'All items include standard hardware and delivery to site. Any variations will be quoted before execution.'

It was the opposite of Acme's vague 'installation separate' fine print.

Applying the Lesson

For our next office-related purchase—laptop stands and monitor arms—I used a new rule: before asking 'what's the price?', I ask 'what's NOT included?' If a vendor couldn't tell me in one sentence, I moved on. It saved us roughly $1,200 on that small order alone (no 'assembly required' upcharge, no 'expedited shipping' surprise).

I also started applying this to our construction material buys. PERI's transparent pricing became a benchmark. When I heard a supplier say 'we'll figure out the extras later,' I'd think about that $4,400 overage and politely decline.

The Little Moment That Sealed It

Last month, I was working from home on a Sunday, trying to figure out how to change wallpaper on my Mac (my daughter wanted unicorns). While clicking through System Settings, it hit me: setting a wallpaper is simple because the options are right there. No hidden steps. No extra downloads. That's how procurement should work—all the info upfront.

My experience is based on about 200 mid-range orders with maybe 15 different vendors across office supplies and construction materials. If you're sourcing luxury finishes or high-volume fabricated parts, the specifics may differ. But the principle holds: transparency saves time, money, and stress.

What I Tell Every New Buyer

Don't get me wrong—I still chase competitive pricing. But now I add one question to every RFP: 'Can you send me a complete price list including all potential add-ons?' The vendors who can answer clearly are the ones I trust. The ones who say 'it depends' get a follow-up: 'Then please tell me what it depends on.'

PERI taught me that a higher upfront number with zero surprises is way cheaper than a lowball quote with a ton of asterisks. And that's a lesson I'm not gonna forget.
