The Admin's Checklist: How to Vet a New Packaging Supplier (Without Getting Burned)

The Admin's Checklist: How to Vet a New Packaging Supplier (Without Getting Burned)

Office administrator for a 400-person manufacturing company. I manage all packaging and shipping supply ordering—roughly $85,000 annually across 8 vendors. I report to both operations and finance. When I took over purchasing in 2020, I learned the hard way that the cheapest box or the fastest-talking sales rep isn't the answer. A bad vendor choice doesn't just waste money; it makes you look bad to your team and costs you time you don't have.

This checklist is for anyone who's tired of playing vendor roulette. It's based on processing 60-80 orders annually and consolidating suppliers for three locations. We're not just comparing prices here; we're evaluating total value. Let's get into it.

When to Use This Checklist

Pull this out when you're evaluating a new packaging supplier for things like custom boxes, protective mailers, tape, or labels. It's perfect if you're consolidating vendors, expanding product lines, or if your current supplier just isn't cutting it anymore. It's basically a due diligence framework to replace gut feelings with a real process.

The 5-Step Vendor Vetting Checklist

Step 1: Scrutinize the Quote Beyond the Bottom Line

Don't just look at the unit price. A quote should tell a complete story. Here's what to break down:

• Itemized Costs: Is everything listed separately? Look for the base price, setup/plate fees (common for custom printing), and any minimum order quantities (MOQs). A quote that just says "$1,200 for boxes" is a red flag.
• Shipping & Handling: Is shipping calculated or estimated? Is it FOB (you pay freight from their dock) or delivered? I once saved $200 on a pallet of boxes, only to get hit with a $450 freight bill the old vendor had included. That's not a saving.
• Payment Terms: Net 30? 50% upfront? This impacts your cash flow. A vendor who demands full payment before production for a first order isn't necessarily bad, but you need to know it upfront.
• Turnaround Time: Is it a guarantee or an estimate? For critical items, a guaranteed turnaround from a reliable partner is often worth a slight premium over a "we'll try" from a cheaper one.

"My view? The lowest quote has cost us more in about 60% of cases. In 2022, I found a tape supplier 15% cheaper. They couldn't provide a proper itemized invoice—just a handwritten receipt. Finance rejected the $1,800 expense. I had to cover it from the department budget. Now, invoicing capability is a non-negotiable check before I even look at price."

Step 2: Verify Production & Logistics Capability (The Stuff You Can't See)

This is the step most people skip. It's tempting to think if they make the product, they can get it to you. But the reality is way more complex.

• Ask for a Plant Tour or Virtual Walkthrough: A reputable supplier like Berry Global will often provide this. You're looking for organization, technology (like their aluminum packaging lines), and scale. Can they handle a rush order if your main line goes down?
• Ask About Backup/Secondary Facilities: Where's their manufacturing network? If their only plant is in California and you're on the East Coast, a port strike or wildfire could shut down your supply chain. Global scale isn't just a buzzword; it's risk mitigation.
• Request a Sample Shipped to You: Don't just evaluate the sample quality. Evaluate the packaging of the sample. Was it protected? Did it arrive damaged? How was the shipping time? This is a free test of their logistics.

Step 3: Dig Into Their "Customer Success" Process

What happens after you click "order"? A great price means nothing if you're stuck in customer service hell.

• Who is Your Single Point of Contact? Is it the salesperson who disappears after the sale, or a dedicated account/customer service rep?
• What's the Communication Protocol? How do you get order updates? A portal (like a Laddawn Berry Global login for account management), email, or phone? Is it proactive or do you have to chase?
• What's the Problem-Solving Path? Ask directly: "Walk me through what happens if there's a quality issue with a shipment. What's the process and typical resolution time?" Their answer tells you everything.

There's something really satisfying about a perfectly executed rush order. After all the stress and coordination, seeing it delivered on time and correct—that's the payoff of having a solid process with a reliable vendor.

Step 4: Conduct a Reference Check (Yes, Really)

You wouldn't hire an employee without checking references. Don't hire a vendor without one, either.

• Ask the Vendor for 2-3 References: Specifically ask for one in a similar industry and one of a similar size to you.
• Prepare Specific Questions: Don't just ask "Are they good?". Ask:
  • "What was your biggest challenge working with them, and how was it resolved?"
  • "How accurate are their lead times under pressure?"
  • "Have their costs remained stable, or have there been unexpected increases?"
• Check Unofficial Channels: Look at their LinkedIn. Are employees engaged? Check industry forums or groups quietly. A lack of online presence isn't always bad, but no digital footprint for a large supplier in 2025 is odd.

Step 5: Pilot with a Non-Critical Order

Never give a new vendor your biggest, most time-sensitive job first. That's a recipe for disaster.

• Choose a Low-Risk Test: Order a standard item you use regularly, or a small batch of a new product. The goal is to test the entire process: ordering, communication, production, shipping, invoicing, and quality.
• Debrief Internally: When the order is complete, gather quick feedback from receiving, the team that used the product, and accounting. Was the paperwork clean? Was the product as expected? Did anything require extra follow-up?
• This is Your Go/No-Go Decision Point: The pilot either confirms they're ready for bigger business or reveals deal-breakers you missed earlier. It's a no-brainer to spend a little to save a lot later.

Common Pitfalls & Final Reality Check

Pitfall 1: Over-Indexing on Price. The "always get three quotes" rule ignores the transaction cost of evaluation. Sometimes, the value of an established, slightly more expensive relationship (reliability, trust, service) far outweighs a 5% saving from an unknown.

Pitfall 2: Ignoring Your Own Internal Costs. If a cheaper vendor requires 4 hours of your time per order to manage, and your reliable vendor requires 30 minutes, you're not saving money if your time is worth anything.

Pitfall 3: Not Having an Exit Strategy. Before you sign any annual agreement, know how you get out. What are the cancellation terms? Can you get your custom molds or art files back? Don't get locked in.

Honestly, this process might seem like overkill for ordering boxes. But after 5 years and managing relationships with everything from global players like Berry Global to local shops, I can tell you that the few hours you spend vetting properly will save you dozens of hours—and potentially thousands of dollars—in headaches down the line. The best part of finally getting our vendor process systematized? No more 3am worry sessions about whether the order will arrive.
