I've been handling packaging procurement orders for 6 years. I've personally made (and documented) 11 significant mistakes, totaling roughly $3,200 in wasted budget. This checklist is the result. Use it before you place your next order.
This checklist is for you if you're ordering custom packaging—flexible pouches, rigid containers, or specialty cartons—and you're not a packaging engineer. The people who need this most are brand managers, product developers, and procurement specialists who place packaging orders a few times a year. Not enough to have a dedicated checklist, but often enough that a mistake hurts.
There are 5 steps. Follow them in order.
Step 1: Verify the Material Specification Against What You Actually Need
The most expensive mistake I made was ordering a beautiful, glossy, multi-layer flexible pouch for a product that needed to be frozen. The pouch looked great. It also shattered in the freezer after a week.
Most buyers focus on the visual spec—color, finish, print—and completely miss the functional spec. The question everyone asks is 'can you print this design?' The question they should ask is 'what's the storage and distribution environment for this product?'
Checklist items for this step:
- What is the temperature range the packaging will experience? (e.g., -20°C freezer to 40°C warehouse)
- Will the product be shipped? What are the handling risks (drop, crush, vibration)?
- Does the packaging need a barrier? For oxygen? Moisture? Light?
- Is this for a new product? If so, the R&D specification is a starting point, not a finished spec.
In my first year (2017), I ordered 5,000 custom-printed polybags for a client's skincare line. The material spec said 'standard polyethylene.' It was fine on my screen. The result came back—the bags didn't have an oxygen barrier. The product oxidized in 3 months. 5,000 bags, $1,200, straight to the trash. That's when I learned to always ask about the product's shelf life requirements.
Step 2: Validate the Dimensions with a Physical Mock-Up (Not Just a CAD File)
CAD files lie. Or rather, they tell the truth perfectly, which is not the same as reality. A CAD file doesn't account for the thickness of a zipper closure, the take-up from a heat seal, or the fact that your product isn't a perfect cylinder.
I once ordered 2,000 rigid plastic containers for a powdered supplement. The CAD file showed the container, the lid, and the scoop fitting perfectly. In reality, the scoop was 2mm too long to fit inside the closed container. The error wasn't caught until the first production run. Cost: $450 in redo plus a 1-week delay.
Checklist items for this step:
- Get a physical mock-up—at least 3 units—before approving production.
- Test the mock-up with the actual product, including any inserts or components (scoops, spoons, leaflets).
- Check the fill line. If the package is supposed to look full, does the product reach the right height?
- Test the closure. Open and close it 10 times. Does the lid crack? Does the zipper seal properly?
I should add that many online printers and packaging suppliers offer digital mock-ups that are free or cheap. They're better than nothing. But a physical sample is never optional for a first-time order.
Step 3: Clarify the Quoted Price—What's Included and What Isn't
This was true 10 years ago when pricing was more opaque. Today, most suppliers are upfront, but the devil is in the unspoken line items. The $500 quote turned into $800 after shipping, setup, and revision fees. The $650 all-inclusive quote was actually cheaper.
From my perspective, the most commonly overlooked cost is the revision fee. Many suppliers include 1-2 rounds of revisions for free. After that, it's $50-150 per revision hour. If your design team is iterative, that adds up fast.
Checklist items for this step:
- Get a fully itemized quote: material, printing, setup/die charges, shipping, packaging, and any revision fees.
- Ask about minimum order quantities (MOQs). Some suppliers have low unit prices but high MOQs. The TCO might not work for your volume.
- Clarify payment terms. Net 30 is standard. If they want 50% upfront, ask why.
- Ask about rush fees explicitly. Don't wait until you need the order faster.
I now calculate TCO before comparing any vendor quotes. The cheapest per-unit price often comes with the highest hidden costs. It's a framework that's saved me thousands.
Step 4: Establish a Clear Approval Process for Proofs
This is the step that sounds obvious but is almost always where the error lives. The problem isn't that people don't look at proofs. It's that they look at the wrong things.
The question everyone asks about the proof is 'does the color look right?' The question they should ask is 'is every element exactly where it's supposed to be?' Color can be off and still acceptable. A barcode placed 2mm too close to the edge can render the entire package unsellable.
Checklist items for this step:
- Create a proof review checklist that includes: barcode position and readability, copy accuracy (including legal disclaimers), seal area clearance, and die-line position.
- Assign one person to be the final approver. Too many cooks = errors.
- Use a red pen (or digital annotation tool) to mark changes. Verbal approvals are dangerous.
- Send the proof to 2 people—preferably one who knows the design and one who knows the production requirements. They will catch different things.
After the third rejection in Q1 2024, I created our pre-check list. We've caught 47 potential errors using this checklist in the past 18 months. The most common: copy errors and barcode placement.
Step 5: Plan for the 'What If'—Lead Time, Buffer, and Backups
Had 2 hours to decide before the deadline for rush processing for a key client's product launch. Normally I'd get multiple quotes, but there was no time. Went with our usual vendor based on trust alone. In hindsight, I should have pushed back on the timeline. But with the product team waiting, I made the call with incomplete information.
Luckily, the order arrived on time. But it was a close call, and it taught me a lesson: always build a buffer into your timeline.
Checklist items for this step:
- Ask the supplier for their standard lead time and their worst-case lead time. Budget for the worst-case.
- Plan a buffer of at least 1 week for standard orders, 2-3 days for rush orders.
- Have a backup supplier vetted and ready. You don't have to use them, but you should know who they are and have a quote on file.
- If the order is for a critical launch or event, consider a split order—20% from a secondary supplier, 80% from the primary. It adds cost but removes risk.
Common Mistakes to Watch For
Here are the most common errors I see that don't fit into the 5 steps above:
- Ignoring the shipping packaging. You ordered beautiful boxes. They arrived crushed because the outer shipping carton was too thin. Ask about how your order will be packaged for shipment.
- Assuming 'standard' means 'same as last time.' It doesn't. Verify every time.
- Forgetting about the c/o envelope. If you're shipping samples in a box, the address label matters. A single wrong character can cause a 3-day delay.
- Ordering a perfume gift box without checking the insert. The box fits the bottle. The bottle doesn't fit the foam insert. Common.
And a final note on pricing: as of January 2025, the setup fees for custom packaging are fairly consistent. Expect $15-50 per color for offset plates, and digital setup is often free. Rush fees, if you need them, add 25-50% over standard pricing. Verify current rates with your supplier, as these can shift.
