The Cost Controller's Checklist: 7 Things I Check Before Approving an Education Supply Order

If you approve purchase orders for a school, lab, or small district, this checklist is for you. It's not a supplier evaluation framework. It's the exact list I run through before I hit approve—and it's saved me more than once.

I've managed our education supplies budget for 6 years now. That's about $180,000 in cumulative spending across lab materials, office supplies, printer consumables, and the occasional last-minute order. I'm not a procurement consultant and I don't have a certification. What I have is a spreadsheet full of invoices and the scars from a few bad decisions.

Here's the thing: the cheapest quote is rarely the lowest total cost. But you don't have to learn that the expensive way. Run these checks first.

Step 1: Verify you're actually on the supplier's official website

Before you log in, type the URL yourself. If you search for Nasco Education official website, look for the domain to match before you enter any school or PO details. I've had staff ask me, Is Nasco Education legit? My answer: I check three things—the domain, the contact page, and whether the order process matches what a legit distributor would ask for.

I'm not a cybersecurity expert, so I don't pretend to do deep technical verification. But a legitimate education supplier will have a clear business address, a phone number you can call, and a purchase order process that doesn't require gift cards. That last one matters more than you think.

Per FTC business guidance on advertising (ftc.gov), a company's claims about itself have to be substantiated. I apply the same standard to every supplier. If a catalog says discounted, I want to know what the discount is based on. If it says in stock, I ask for a delivery date.

Step 2: Use the right calculator for what you're comparing

I'm a spreadsheet person, so I don't mean a literal calculator app. I mean you need the right model for the decision.

Think about a Starbucks calorie calculator and an APUSH score calculator. Both are useful, but you wouldn't use one for the other. The same is true for supplier price comparisons. A unit price comparison won't tell you the real cost of an order. You need a total cost of ownership model:

• Product price
• Freight and handling
• Minimum order fees
• Restocking or return fees
• Admin time to handle backorders or damage

I built this cost calculator after getting burned on hidden fees twice. The second time, I realized the problem wasn't the vendor—it was my checklist.

Step 3: Look for the fees that aren't on the price list

Small orders are the ones that get hit with the weird charges. I've sat through enough vendor meetings to know that going under $100 often triggers something that should have been disclosed upfront. That's not always malicious; sometimes it's just buried in the terms.

When I was starting out, the vendors who treated my $200 orders seriously are the ones I still use for $20,000 orders. Small doesn't mean unimportant—it means potential. And a vendor that adds a $25 processing fee to a $150 order without flagging it? That tells me how they'll treat a big order too.

Ask about:

• Minimum order thresholds
• Small-order surcharges
• Setup or fulfillment fees
• Return restocking percentages

Write them down. If a quote says free shipping but the invoice has a handling charge, that's not free shipping.

Step 4: Clean the printer heads before you reorder cartridges

This one sounds unrelated to procurement, but it's where I've saved the most money. If someone submits a request for a new printer cartridge because the printer prints blank pages, don't approve the order yet. Learn how to clean printer heads first.

Most inkjet printers have a built-in cleaning function. You can run it from the printer's software or the display panel. Here's the quick method I use:

1. Open the printer utility and find the print head cleaning option, usually under maintenance or settings.
2. Run the cleaning cycle once, not ten times. Over-cleaning wastes ink.
3. Print a test page. If the missing lines come back, run the cycle once more.
4. If that doesn't work, try a manual clean with a lint-free cloth and a tiny bit of distilled water on the print head—the details should be in your printer's manual, not my memory.

I'm not a printer technician, so I can't speak to every model. But I can tell you from a budget perspective: replacing a cartridge because the old one wasn't cleaned is a $30 mistake multiplied by every classroom printer. A cleaning cycle costs almost nothing.

Step 5: Check your own inventory before you reorder lab supplies

This is the step people skip because it's boring. Before you place an order, have someone check what's actually in the storage closet. For science lab materials, expiration matters. If you use prepared lab cultures—like the bacillus subtilis culture our biology section orders—check the date on the vial before you add it to the cart.

I wish I had tracked our lab inventory more carefully from the start. I can tell you anecdotally that we're out usually means we can't find it about 20 percent of the time. That's not a hard number. I don't have perfect data on findability versus actual stockouts. But after six years of watching orders arrive for things we already owned, my sense is that the number is high enough to check.

If you're ordering through Nasco Education or another broad-line supplier, make one person responsible for the inventory list. It doesn't need to be fancy. A shared spreadsheet works if someone keeps it current.

Step 6: Compare quotes with the same assumptions

When I compare vendors, I don't compare Vendor A's best price to Vendor B's quoted price. I put every quote into the same template. That sounds obvious, but it's not what most people do.

After comparing 8 vendors over 3 months using our TCO spreadsheet, I found that a $3,200 quote was actually cheaper than a $2,900 quote because the lower quote didn't include freight, had a higher minimum, and required a $150 delivery window fee for our address. The difference was 11 percent in the fine print.

That's the reason I built the template. It's also why our procurement policy now requires quotes from three vendors minimum for anything over $500.

Step 7: Add a 10 percent buffer and ask what you're missing

Before I approve any order, I add 10 percent to the total in my head. If the budget is tight, I ask the supplier one direct question: What else is this order going to cost that isn't on the quote?

I don't have hard data on how often that question saves money, but it's saved me from at least four surprise invoices. That's enough for me to keep asking.

And if a vendor makes you feel small because your order is small? Move on. A good supplier—one you can trust for a $200 order or a $20,000 order—will treat your budget like their own.
