A 6-Step Pre-Order Checklist (Born From 3 Expensive Mistakes)

I manage procurement for a mid-sized mining equipment supplier. For about 2 years, I thought I knew what I was doing. Then, within a single quarter in 2022, I made three separate mistakes that collectively cost us over $12,000 in rework, expedited shipping, and lost client goodwill. That's when I stopped relying on memory and started using a pre-order checklist.

It's not sexy. It's a list. But since implementing it, our error rate has dropped by roughly 80%. Here's the checklist I wish I'd had. If you're placing orders for custom parts, field equipment, or specialized tooling—especially if you're dealing with tight margins and tighter deadlines—this is for you.

When to Use This Checklist

Use this checklist before you press 'send' on any purchase order that meets these criteria:

• Involves custom specifications or made-to-order items
• Exceeds $1,500 in value
• Has a hard deadline (tied to a project or installation)
• Comes from a new or infrequently used supplier

If your order hits any two of those, run the checklist. It takes about 15 minutes and will save you the headache I went through.

Step 1: Confirm the Technical Specs (Out Loud)

This sounds obvious. But my first $5,000 mistake happened because of it. I ordered a custom hydraulic hose assembly. The part number was correct on the PO. The supplier's system accepted it. Two weeks later, the wrong hoses arrived. Turns out, the part number was for the previous revision.

The fix: Before you finalize the PO, take the spec sheet and read the key numbers out loud to the supplier. Not email. Not text. A phone call. Say: 'Confirm you have Revision C of drawing 47-992 for the 6-foot assembly with the 90-degree fitting.' Get a verbal confirmation. It forces you to double-check and catches human error on both sides.

It also forces you to check the units. I once saw an order for 1" steel plate. They ordered 1 cm. (circa 2023, we caught it before it went through).

Step 2: Confirm the Delivery Promise (In Writing)

My second costly error. I had a verbal agreement with a supplier—'It'll be there by the 15th.' I didn't get it in writing. On the 14th, I called to confirm. They said, 'Oh, we're backlogged; it's shipping on the 19th.' No proof of the original promise. My mistake. That delay caused a 3-day installation postponement and a $2,000 penalty clause.

The fix: After your verbal call (Step 1), send a short confirmation email: 'Just to confirm our call today—you said the order for PO# 12-345 will be dispatched by [DATE] via [CARRIER] with delivery by [DATE]. Please confirm.' You need a paper trail. It's not about distrust; it's about eliminating ambiguity.

Step 3: Check the Total Cost (Not Just the Unit Price)

The $500 quote looked cheap. But after adding: shipping ($85), a hazardous materials surcharge ($40), and a revision fee because the drawing wasn't clear ($120)—the total was $745. The competitor's all-inclusive quote was $680. I learned this the hard way (the $12k quarter).

I now calculate Total Cost of Ownership (TCO) before comparing. The checklist item is simple: ask for a final 'all-in' price including every fee. Don't be shy. Say: 'Is there any chance my final invoice could be higher than this quote?' If they hesitate, there's a hidden charge waiting for you.

Step 4: Verify the Payment Terms (Yes, This One)

I almost skipped this. I knew I should review the terms but thought, 'what are the odds?' The odds caught up with me when a supplier applied a 3% surcharge for using a credit card—which I had to do because their net-30 terms actually required payment within 14 days, and our AP cycle was 30 days. (Surprise, surprise).

The fix: Three quick questions:

1. What are the exact payment due dates? (Not 'Net 30'—what's the specific date?)
2. Are there any surcharges for any payment method?
3. What happens if we need to pay in 45 days? (The answer tells you how flexible they are.)

Step 5: Run a 'Worst Case' Scenario

This is the step most people ignore. When you're excited about the project, you plan for success. I now force myself to ask: What's the worst thing that could happen with this order?

It's usually one of three:

• It arrives late. What's our backup plan? (Notify the client early, have a workaround.)
• It arrives wrong. How long will a replacement take? (Ask the supplier their re-order lead time.)
• It's damaged in transit. Who pays? (Are we insured? Who files the claim?)

Skipping this step because you're rushing is a classic overconfidence fail. I know because I've done it. 'It'll be fine' are the four most expensive words in procurement.

Step 6: Do the 'Fresh Eyes' Review

When you've looked at a PO for three days, you stop seeing errors. I said 'standard size' in one order. The supplier heard 'SAE standard.' I meant 'metric standard.' We discovered this when the order arrived and nothing fit our existing materials. $450 in rework and a week delayed.

The fix: If you can, have someone else review the final PO. Someone who hasn't been involved. Ask them to read it as if they were the supplier. If your colleague doesn't understand something, the supplier probably won't either.

We've caught 47 potential errors using this checklist in the past 18 months. That's a lot of headaches avoided. (Not that we're counting—actually, yes, we are. It helps justify the process.)

A Few Notes on Execution

• This is not a suggestion. Make this a mandatory gate in your procurement workflow. If Step 2 (written confirmation) isn't done, the order doesn't go out.
• Under USPS regulations (effective January 2025), if you're shipping physical items, a standard letter costs $0.73. A large envelope for documents (like packing slips) is $1.50. Don't overpay for shipping.
• Per FTC guidelines, any claims about 'quickest delivery' or 'best service' need to be substantiated. Don't make promises on behalf of your supplier that you can't back up.

The checklist looks simple. That's the point. The errors I made weren't complex; they were failures of process, not knowledge. A $500 mistake taught me that. (This was back in 2022, and things have changed, but the lesson stuck.)
