The Back to School Procurement Checklist Every School Admin Buyer Needs

Office administrators at schools don't get a slow season. But back to school is its own animal. Between supply orders, budget spreadsheets, and the inevitable wireless printer meltdown, the six weeks before classes start are a marathon.

I've managed purchasing for a K-8 school of about 400 students since 2020—roughly $150,000 a year across 15 vendors. I report to both operations and finance, so I've learned to plan carefully and check every invoice. I didn't learn that overnight. The mistakes below are the ones that taught me.

This is the back to school procurement checklist I follow every August. Five steps, in order. Step 2 is the one most people skip, and it's saved me the most money.

Step 1: Inventory what you actually have before ordering

Walk every classroom. Count tape dispensers, scissors, glue sticks, markers, construction paper. Open every cabinet. What you think needs replacing is rarely what actually needs replacing.

In 2021, I ordered 40 replacement glue guns because a teacher mentioned that the supply closet was nearly empty. Turns out there were 60 in a locked cabinet in the art room. I sent the order back and paid a restocking fee. $250 wasted because I trusted a passing comment instead of checking a shelf.

Schedule the inventory walk two weeks before you plan to order. That gives teachers time to request what they need and gives you time to consolidate requests into one order instead of three. I keep a simple shared spreadsheet for this: teacher names down the side, items across the top. It prevents the "I asked for it, where is it?" conversations later. The spreadsheet also doubles as a paper trail for next year—when the same requests come up again, you can see what actually got used.

Step 2: Use a dividend calculator to allocate budget per classroom

This is the step most schools skip, and it's the source of most budget fights.

It's tempting to think you can just take your total supply budget, divide it by the number of classrooms, and be done. But a kindergarten room doesn't need the same materials or quantities as a 5th-grade science room. Split it evenly and you'll be out of money by October.

To do this right, use a dividend calculator. I don't mean the stock-market kind. In math terms: the dividend is what you're dividing up. Your total supply budget is the dividend. Your classroom count is the divisor. The quotient is each classroom's baseline share. This gives you a defensible number before emotions enter the conversation.

Then weight it:

• Early childhood classrooms: 1.3× the baseline
• Science classrooms: 1.15× (consumables go fast)
• General classrooms: baseline

Example: $30,000 budget across 20 classrooms gives you a $1,500 baseline. Kindergarten gets $1,950. The science room gets $1,725. Everyone else gets $1,500.

Write these numbers down before you order. When a teacher asks for extras, point at the classroom's share. The numbers do the arguing. And after the order arrives, track what each room actually used, so next year's dividend calculation gets more accurate.

Step 3: Time your Lakeshore Learning back to school sale order

Once the inventory is done and the budget is allocated, the next thing is actually buying the supplies. I order most classroom staples from Lakeshore Learning. The Lakeshore Learning back to school sale runs every summer, and the teacher discount stacks on top of sale prices. (Their teacher discount was 15% as of 2024—the terms are worth verifying each year.)

But the sale becomes a trap if you let the timeline control you.

In 2023, I delayed a large order for three weeks, waiting for steeper discounts. Then the email arrived: "Last day of the back to school sale!" I panic-placed the order and paid $80 for expedited shipping. The discount was $37. I lost money. I bought the rush, not the deal.

The lesson: when the Lakeshore Learning back to school sale goes live, order early. Historically, the sale runs from mid-July through late August (accurate as of 2024—verify the dates since they shift slightly). Lock in the price and confirm the delivery date. In back to school, the calendar isn't negotiable.

While you're ordering, don't ignore the boring items. Construction paper, bulletin board rolls, chart paper, laminating sheets—those run out faster than anyone predicts. And the tape dispenser is the best example of buying right. For years, I bought cheap single-pack dispensers from a big-box store. They'd crack by November and need replacement again by spring. Then I switched to a Lakeshore Learning tape dispenser. The one I ordered in 2022 is still on a teacher's desk today. Same goes for scissors and pencil sharpeners—buy the better version once.

Step 4: Get your wireless printer back online before day one

Every year, at least one teacher discovers on the first day that the printer isn't working. It's rarely a hardware problem. It's a timing problem—they notice it at the worst possible moment.

Wireless printers go offline for three standard reasons:

• The printer is connected to a different Wi-Fi network than the computer
• The printer dropped into sleep mode and isn't waking up
• The printer's IP address changed after a network update

Here's how to get printer back online with four quick checks:

1. On the printer's control panel, open the network menu and check Wi-Fi status. If it's disconnected, rejoin the same network your computers use.
2. Press the power button twice. It might just be sleeping. (Not great design, but very common.)
3. On Windows: Settings → Devices → Printers & Scanners. Remove the printer, then click "Add a printer" to re-detect it.
4. On Mac: System Preferences → Printers & Scanners. Remove the printer, then add it back.

If it's still offline, restart both devices at the same time. Turn them off, count to 30, power them back up. It sounds like a superstition. It works often enough.

Do this one week before school starts, not the day before. If a printer needs to be replaced, you want time to order a new one without paying rush shipping. Certainty beats speed—but only if you plan it.

Step 5: Confirm invoices and delivery dates in writing

This step protects you when something goes wrong. I learned it the hard way.

In 2022, I found a bulk pricing deal from a new vendor—$600 cheaper than my usual supplier. I placed the order without checking their invoicing process. The invoice arrived as a handwritten receipt with no tax ID. Finance rejected the expense report. I ate $600 out of the department budget. The cheapest price is meaningless if you can't prove you paid it.

Now I verify invoicing capability before placing any order. And I confirm delivery dates in writing—not the "estimated" dates on the checkout page. A written confirmation of the exact delivery date.

In March 2024, we needed a rush order for a school event. I had two hours to decide: pay $400 extra for guaranteed delivery, or take the cheaper estimate and hope. Normally I'd get three quotes and run a comparison. There was no time for that. I made the call based on a vendor I trusted and paid the premium. I regretted the cost for a week. The delivery date was confirmed in writing, the order arrived on time, and the event went off without a hitch. The $400 was cheap insurance—the event was worth $15,000.

Three Mistakes That Cost More Than the Sale Saves

1. Waiting until the last day of the sale. The Lakeshore Learning back to school sale is a deadline, not a suggestion. The sale is the event. Your ordering deadline is a separate date you set yourself. If you miss both, don't compound the mistake by waiting until you need expedited shipping to fit the delivery window. Rush shipping eats your savings faster than any discount. When USPS adjusted ground rates in July 2024, those expedited options got even pricier. If you're late, accept it, pay for guaranteed delivery, and move on. The cheap option that arrives after the first day of school isn't cheap.

2. Skipping the inventory walk. You will order glue guns you already have. They will sit in a cabinet until 2026. Thirty minutes of walking around saves hundreds of dollars.

3. Ignoring the printers. "Maybe it'll work on day one" is not a plan. Test the wireless printers in August. If one won't stay online, replace it before the first day. Replacing a printer during the first week of school is a different, much more painful project.
