I've been handling packaging and print orders for Berlin Packaging for about six years now. In that time, I've personally made—and more importantly, documented—over a dozen significant mistakes that collectively wasted roughly $5,000 of our budget. That's not counting the embarrassing ones that just cost time. I now maintain a checklist for our team, and honestly, it's saved us way more than it cost to create. This article is basically that checklist in story form, plus the specific errors that taught me each point.
Who this is for: Anyone ordering packaging or print materials for a small business. If you're buying boxes, flyers, business cards, or even custom tape for the first time, you're in the right place. I'm gonna walk you through the five biggest mistakes I've made (so you don't have to), and then give you a simple checklist to run through before your next order.
Step 1: Get the exact specs, not just a vague idea
This sounds obvious. It isn't. My first major mistake was ordering 500 custom-printed boxes for a product launch in 2018. I told the supplier, "I need a box that fits this widget." They asked for dimensions, I gave them rough measurements. The boxes arrived, and the widgets didn't fit. They were about a quarter-inch too small.
The mistake: I didn't account for the thickness of the product's packaging inside the box. I measured the widget itself, not the widget in its retail sleeve. The result: $450 worth of boxes that were useless, plus a 1-week delay while we ordered replacements. The lesson? Always provide the exact internal dimensions you need, including any internal packaging. If you're not sure, order a sample first—it's cheap insurance. And use a ruler, not your eyes.
Real talk: When I compared our Q1 and Q2 results side by side—same vendor, different specifications—I finally understood why the details matter so much. The quarter-inch difference made our product look unprofessional. That's a bad look for a brand.
Step 2: Calculate weight and postage before you order
This one cost me about $300 in extra postage over six months. I was ordering padded envelopes and bubble mailers for our customer shipments. I assumed that because a standard #10 envelope weighs about 0.16 ounces empty, a bubble mailer would be similar. Wrong.
The bubble mailer I was using weighed 0.8 ounces empty. Add a product and some paperwork, and suddenly it weighed 1.2 ounces. That pushed it into a higher postage bracket. So I went from paying $0.73 per letter (for a regular envelope) to $1.16 per package (for the bubble mailer)—which was fine, but the $0.73 to $1.16 jump was a surprise that ate into our margins.
The fix: Weigh everything. Literally everything. Get a small postal scale (they're like $20-30 on Amazon). Weigh your empty box or envelope. Weigh your product with all its inserts. Add 10% for tape and labels. Then check the postage rates for that weight. You can find current rates at the USPS website.
And if you're wondering how many stamps you need for a standard envelope weight, the answer is: usually one Forever stamp for up to 1 ounce. But if it weighs more, you need additional postage. I've had customers call asking about that exact question, and I always recommend they use the USPS postage calculator. It's free and accurate.
Step 3: Get a proof, and actually check it
In 2021, I ordered 1,000 barber flyer templates for a local shop. They were using one of our standard templates. I approved the digital proof, but I didn't zoom in on the barber's phone number. It was a typo—one digit off. When the flyers arrived, the number was wrong. The barber was not happy.
Cost of that mistake: $180 for the reprint (the supplier kindly gave me a discount after I admitted fault) plus the embarrassment of delivering misleading information. I still cringe thinking about it.
The procedure now: Always print the proof on your own printer at home. Look at it. Check every number, every URL, every email address. Run your finger under each line of text. Read it out loud. If you're ordering a large quantity, get a physical sample from the printer. Most online printers offer this for a small fee. It's worth it.
Business card pricing comparison for reference (500 cards, 14pt cardstock, standard turnaround): Budget tier runs around $20-35, mid-range $35-60, premium up to $120. But regardless of the tier, a typo is a typo. Proofing doesn't cost extra; not proofing does.
Step 4: Don't just look at the unit price—look at the total cost
I ordered 2,000 sheets of vinyl wrap for a project. The base price was okay, but I didn't check the shipping cost or the setup fee. Shipping ended up being $80, plus there was a $25 setup fee for the custom cut. I saved $0.05 per sheet by choosing the "budget" option, but the total cost was actually higher than the mid-range vendor who offered free shipping on orders over $100.
Saved $100 by going budget? Ended up spending an extra $55 on shipping and setup. Net loss: $55, plus the headache of dealing with slow shipping. I call this the "penny wise, pound foolish" mistake. It's super common.
The checklist item: Before you click "order," add up the base price, shipping, setup fees (if any), and any taxes. Compare the total cost across at least two suppliers. Don't assume the cheapest per-unit price is the cheapest total.
Setup fees in commercial printing typically include plate making ($15-50 per color), digital setup ($0-25 for online printers), and die cutting setup ($50-200). Many online printers include setup in their quoted prices now, but not all. Always ask.
Step 5: Always include a buffer for shipping time
In 2023, I needed a rush order of custom-printed boxes for a trade show. I ordered them with standard shipping, thinking the 5-day turnaround was enough. But I didn't account for the fact that the supplier's "5 business days" didn't include the day I placed the order. And then there was a holiday. And then FedEx was slow. I ended up paying an additional $200 for expedited shipping to get them there on time.
The math: Standard 5-day turnaround + 2 days for production + 3 days for shipping = 10 days. I had planned for 7. The rush fee cost me $200, plus the stress.
Rush printing premiums: Next business day usually adds 50-100% over the base price. 2-3 business days adds 20-50%. Same day is rare but can cost double. My rule now? Always add at least 3 days to whatever the supplier's estimate is. If they say 5 days, plan for 8. If it arrives early, that's a win.
Final checklist for your next order
- Specs: Internal dimensions, weight, material thickness. Write them down. Confirm with supplier.
- Proof: Print it at home. Check all details. Read out loud.
- Postage: Weigh your complete package. Use a postal scale. Verify rates.
- Total cost: Add up base price + shipping + fees. Compare with at least one other supplier.
- Timeline: Add 3 days to the supplier's estimate. Plan for delays.
- Supplier: Read reviews. Ask for references if you're doing a big order.
These mistakes cost me about $5,000 over five years. That sounds like a lot, and it is. But I've caught 47 potential errors using this checklist in the past 18 months alone. So the checklist has paid for itself many times over.
One last thing: Don't be afraid to call the supplier. If you're not sure about something, ask. I've had reps at Berlin Packaging explain things like the difference between coated and uncoated paper stocks, or the best way to package a heavy product. They're usually happy to help. And if they're not, that's a red flag.
Good luck with your next order. You've got this.
