How to Vet a Packaging Vendor Before Your First Big Order: A 9-Step Checklist

How to Vet a Packaging Vendor Before Your First Big Order: A 9-Step Checklist

Office administrator for a 340-person company here. I manage all packaging and materials ordering—roughly $85,000 annually across 6 vendors. I report to both operations and finance, which means I get squeezed from both sides when something goes wrong.

This checklist exists because I learned the hard way. In 2021, I found a great price from a new packaging supplier—$1,200 cheaper than our regular vendor for a quarterly order. They couldn't provide a proper invoice (handwritten receipt, no line-item breakdown). Finance rejected the expense report. I ate $1,200 out of the department budget and had to explain it to my VP.

Nine steps. That's it. Run through these before placing any order over $2,000 with a new vendor, and you'll avoid the mistakes I made.

Step 1: Verify Invoice and Documentation Capability

Before anything else—before samples, before pricing negotiations—confirm they can provide documentation your finance team will accept.

Ask for: a sample invoice from a comparable order. Not a quote. An actual invoice they've sent to another customer (redacted if needed).

Check for:

• Line-item breakdown (materials, labor, shipping separated)
• Tax ID or business registration number
• Net payment terms clearly stated
• PO reference field

What most people don't realize is that "we'll figure out invoicing later" always means problems. If they hesitate on this request, walk away. The vendor who couldn't provide proper invoicing cost us $2,400 in rejected expenses over two orders before I caught on.

Step 2: Request Physical Samples—And Pay for Them

Free samples are marketing materials. Paid samples are production samples.

Here's something vendors won't tell you: free samples often come from a different production run than your actual order. They're cherry-picked. I learned this after ordering 10,000 flexible pouches that looked nothing like the beautiful samples I'd approved.

Request a paid sample run of 50-100 units using the same materials and process as your production order. Yes, it costs $200-500. Yes, it's worth it.

For packaging specifically, check:

• Seal integrity (actually try to tear it open)
• Print registration accuracy
• Material consistency across samples
• How it performs under your storage conditions

Step 3: Confirm Production Capacity for Your Volume

From the outside, it looks like any vendor who quotes your job can handle it. The reality is many suppliers quote jobs they'll need to outsource or squeeze into an already-full schedule.

Ask directly: "What percentage of your monthly capacity would my order represent?"

If your order is more than 30% of their capacity, you're at risk. They're either going to rush it, outsource part of it, or bump you when a bigger customer calls.

According to packaging industry benchmarks, healthy vendor utilization runs 60-75% of capacity. Above 85%, expect delays. This isn't vendor-bashing—it's physics. Machines break. Staff gets sick. Buffer matters.

Step 4: Get Timeline Commitments in Writing

Verbal promises mean nothing. I've been burned twice by "probably on time" promises.

Get written confirmation of:

• Art approval turnaround (usually 2-3 business days)
• Production start date after approval
• Production duration
• Shipping method and transit time
• What happens if they miss the deadline

That last one is critical. A vendor confident in their timeline will offer something—rush priority on the next order, partial refund, credit. A vendor who won't put consequences in writing is telling you something.

In March 2024, we paid $400 extra for guaranteed delivery from a vendor like Amcor's Shelbyville facility. The alternative was missing a $15,000 product launch event. The certainty was worth every penny.

Step 5: Check References—But Ask the Right Questions

Everyone asks for references. Almost nobody asks useful questions.

Don't ask: "Were you satisfied with their service?" (They'll say yes—these are handpicked references.)

Ask:

• "What's the biggest problem you've had with them, and how did they handle it?"
• "Have they ever missed a deadline with you? What happened?"
• "If you had to switch vendors tomorrow, what would you miss most?"

The most frustrating part of reference checks: everyone's on good behavior. You'd think references would be honest, but they're performing too. Listen for hesitation. Listen for what they don't say.

Step 6: Understand Their Supply Chain Exposure

This step is one most people skip. It matters.

Ask: "Where do your raw materials come from? Do you have backup suppliers?"

After the 2021-2022 supply chain disruptions, I started asking every packaging vendor about their material sourcing. One vendor admitted 90% of their specialty film came from a single overseas supplier. We passed—and six months later, they had a three-month backlog when that supplier had production issues.

Large packaging companies like Amcor PLC (which operates facilities across multiple continents, including the Shelbyville location) typically have more supply chain redundancy than regional players. That's not a knock on smaller vendors—it's just a factor to weigh. Per Amcor's company profile, they maintain global manufacturing footprint specifically for supply continuity. Whether that matters depends on your risk tolerance.

Step 7: Verify Sustainability Claims

People assume "recyclable" on packaging means it's recyclable. What they don't see is the fine print.

Per FTC Green Guides (16 CFR Part 260), a product claimed as "recyclable" should be recyclable in areas where at least 60% of consumers have access to recycling facilities that accept it. Many flexible packaging materials technically can be recycled but aren't accepted by most municipal programs.

If sustainability matters to your brand (or your customers), ask:

• What certification backs this claim? (Look for How2Recycle, FSC, or similar)
• What percentage of consumers can actually recycle this through curbside programs?
• What's the post-consumer recycled content percentage?

I'm not saying reject vendors without perfect sustainability credentials. I'm saying verify what they're actually claiming. "Sustainable packaging" without specifics is marketing, not a specification.

Step 8: Test Their Communication Responsiveness

Before you need them urgently, test how they respond to non-urgent requests.

Send an email with a moderately complex question—something that requires them to check with production, not just forward a spec sheet. Time the response.

My benchmarks after 5 years of managing these relationships:

• Under 4 hours: Excellent
• Same business day: Good
• Next business day: Acceptable
• More than 48 hours: Concern

Now multiply that response time by the stress of an actual problem. That unreliable supplier who took 3 days to answer a simple question made me look bad to my VP when we needed an emergency reorder and couldn't get confirmation for 72 hours.

Step 9: Start Small, Document Everything

Even after all this vetting, don't go all-in on the first order.

Place a smaller initial order—maybe 20-30% of your typical volume. Document:

• Actual delivery date vs. promised date
• Quality compared to approved samples
• Any communication issues
• Invoice accuracy
• How they handled any problems (there's always something)

I still kick myself for not doing this with a vendor in 2022. Went straight to a full production order based on samples and a good sales call. Quality was inconsistent, and by the time we knew, we had $8,000 in packaging we couldn't use for premium products.

Common Mistakes to Avoid

After the third time making the same category of error, I wrote these down:

Mistake 1: Prioritizing price over reliability for critical deadlines. The cheapest quote is worthless if it arrives late. For our Q4 product launches, we now budget for guaranteed delivery rather than trusting estimates.

Mistake 2: Assuming "industry standard" means anything. There's no universal standard for packaging turnaround times, quality tolerances, or communication protocols. Get specifics in writing.

Mistake 3: Not building relationships before you need them. Granted, this requires more upfront work. But the goodwill I'm working with now took three years to develop. When I need a rush order, I have vendors who'll prioritize me because I've been consistent and fair.

Mistake 4: Skipping the finance compatibility check. Your vendor relationship doesn't matter if your accounting team rejects every invoice. Verify invoicing compatibility in Step 1—not after you've placed the order.

The Bottom Line

Nine steps. Takes maybe 2-3 hours total for a new vendor evaluation. Saves you from the $1,200+ mistakes I made learning this the hard way.

Is this overkill for a $500 order? Probably. Use your judgment. For anything over $2,000 or anything tied to a hard deadline, run the checklist.

Don't hold me to this, but I'd estimate this process has saved our company $15,000-20,000 in avoided problems over the past four years. Rough math, but the rejected invoices alone were trending toward $3,000 annually before I implemented the documentation check.

The checklist isn't about distrusting vendors. It's about verifying before you need to trust them.
