Why This Checklist Exists
I'm the office administrator for an 80-person design-build firm. I manage roughly $1.2 million a year in purchasing—engineered wood, framing lumber, job site supplies, janitorial products, and occasionally things that make me question my job title, like the time someone asked me to source Salt & Stone soap for the office gym showers.
It took me about 150 orders and four years to realize I needed a real vetting process. I've had vendors who couldn't produce a proper invoice, a subfloor order that arrived three days late because I ignored the delivery window, and a "great deal" that cost us a full day of rework.
This is the checklist I actually use now. If you're a project manager, office manager, or anyone who handles purchasing for a small to mid-size company, keep it handy.
The Checklist
1. Check the manufacturer's financial health
Before I spec a brand-name material, I look at the company's public numbers. This isn't stock analysis—it's answering one question: will they still exist next year, and can they actually supply the volume?
Take Weyerhaeuser. They're one of the big names in engineered wood, but I still check. In their annual report, Weyerhaeuser's 2023 net sales came in at about $7.6 billion, down from roughly $10.2 billion in 2022. That drop doesn't make them risky; timber markets are cyclical. But it tells me they have the scale to ride out the down cycles, which means my project won't get stuck mid-shipment. I don't need to be a financial analyst—I just want to see whether the segment we buy from is core to their business, and whether the product line is still actively listed on their site.
Rule of thumb: if a product depends on a manufacturer that can't survive a market dip, the real cost shows up later as supply disruption.
2. Match the product to the actual job
This seems obvious, but it's the most common miss I see. For subfloor, the spec might say "Weyerhaeuser Gold subfloor," and someone on site thinks "any 23/32-inch OSB works." It doesn't.
Weyerhaeuser Gold subfloor is a tongue-and-groove OSB panel made for floor applications. Standard OSB without the interlocking profile doesn't handle the same loads, and if you're installing a panel system that relies on the edge connection, swapping it to save $1.50 a sheet can turn into hours of labor and a call-back when the floor squeaks.
I keep a spec sheet for every product we use regularly and send it with the purchase order. It takes ten minutes and eliminates a ton of problems.
3. Order cleanup and finishing supplies before the crew arrives
This one came from a bad Thursday. We finished the subfloor in the morning, and the crew realized the old adhesive residue was still everywhere. Nobody had ordered adhesive remover.
Now I include cleanup supplies in the same purchase order as the materials. I also check the MSDS sheets before ordering anything chemical, because some job sites have restrictions on VOC levels—another hidden cost to catch early. The two products that saved us the most time:
- A citrus-based adhesive remover for scraping off residue from concrete and old flooring.
- Sprayway glass cleaner. I know it sounds unrelated, but when you're finishing a space with glass partitions, the last thing you want is construction dust and fingerprints all over the glazing. Sprayway cleans well and doesn't leave that filmy haze.
It's the boring part of the job, but it's the difference between a clean handoff and a punch-list full of smudges.
4. Take the off-topic requests seriously
Not everything you buy is construction material. Last year, HR asked me where to buy Salt and Stone for the locker room baskets. I'd never heard of the brand. My first instinct was to pass it back. But I've learned these requests show up in every office, and treating them like they don't matter just makes more work later.
The process is the same: verify the vendor, check their invoicing, compare cost per unit, and ask about minimum order quantity. I found Salt & Stone through their wholesale program, set up monthly fulfillment, and stopped getting the question five times a day.
The broader point is to build a flexible supplier list. Just because a product is uncommon doesn't mean it should take three weeks to source. That's a cost no one budgets for.
5. Estimate the total cost, not the sticker price
I'll say it plainly: the cheapest quote is rarely the cheapest purchase. When I compare vendors, I use a simple spreadsheet with these columns:
- Unit price
- Shipping
- Minimum order quantities
- Restocking fee if we over-order
- Lead time
- How many crew days it adds or saves
That last column is the one everyone forgets. If a subfloor panel is $0.80 cheaper but takes three extra days to arrive, the crew's downtime burns through the savings fast. A $1,000 materials win can easily become a $3,000 labor loss.
I got burned once on a $2,400 expense that finance rejected because the vendor only provided a handwritten receipt. Now I verify billing capability before I order, not after. Finance doesn't give me a lot of exceptions, so invoicing accuracy matters from day one.
Mistakes I Still Make
A few things I've learned the hard way:
- Don't trust a promised delivery window if it's not in writing.
- Don't assume the whole product line from a big brand is the same quality. Match the grade to the application.
- Don't let a convenient vendor get complacent. We consolidated to eight vendors, but I still spot-check prices twice a year.
- Don't skip the invoice check. If a vendor can't provide proper itemized invoicing, walk away.
Looking back, I should have built this checklist on day one. At the time, I didn't know what I didn't know. But the process stays the same whether you're buying Weyerhaeuser engineered wood or figuring out where to buy Salt & Stone for the office gym. Verify the source, calculate the real cost, and put the delivery and cleanup logistics in writing.
Bottom line: the boring stuff is where the money and the headaches hide.
