How I Actually Evaluate Packaging Vendors Now (After Getting It Wrong for Years)
Office administrator for a 340-person manufacturing company. I manage all packaging and shipping supplies ordering—roughly $180,000 annually across 6 vendors. I report to both operations and finance, which means I get heat from both sides when something goes wrong.
This checklist is for you if you're evaluating industrial packaging suppliers—flexible packaging, rigid containers, aluminum packaging, that kind of thing. If you're buying office supplies or promotional items, some of this applies, but honestly, the stakes are different. I've only worked with B2B packaging vendors serving manufacturing and consumer goods companies. Can't speak to how this applies to retail or food service.
Total steps: 7. Most people skip step 4. Don't.
Step 1: Verify Invoice Compatibility Before Anything Else
In 2022, I found a great price from a new packaging vendor—$4,200 cheaper than our regular supplier for a quarterly flexible packaging order. They couldn't provide invoices in the format our ERP system accepts. Finance rejected the expense report twice. I spent 11 hours over three weeks getting it sorted. The "savings" cost me more in time than it was worth.
Now I verify invoicing capability before placing any order. Ask specifically:
- Can they generate PO-matched invoices?
- What formats do they support? (PDF minimum, EDI if you need it)
- Do they itemize shipping, handling, and any setup fees separately?
If they hesitate on any of these, that's your answer.
Step 2: Request a Quote for Your Actual Order—Not Their Sample Size
Vendors love quoting their sweet spot quantities. "10,000 units at $0.12 each!" Great. I need 2,400 units quarterly. What's THAT price?
Get quotes for:
- Your typical order quantity
- Your minimum likely order (slow quarter)
- Your maximum likely order (busy season)
The spread between these three numbers tells you more about a vendor than their marketing materials ever will. Some vendors penalize small orders heavily. Others don't scale well. You won't know until you ask.
Step 3: Map Out Total Cost—Not Just Unit Price
I've learned to ask "what's NOT included" before "what's the price."
Total cost of ownership includes:
- Base product price
- Setup fees (tooling, plates, dies—especially for aluminum packaging)
- Shipping and handling
- Rush fees if you ever need them
- Minimum order penalties
- Storage fees for scheduled releases
The vendor who lists all fees upfront—even if the total looks higher—usually costs less in the end. I didn't fully understand this until a "cheap" aluminum packaging quote ended up costing 34% more than the "expensive" one after setup charges.
Step 4: Test Their Specification Process (Most People Skip This)
Everyone warned me about spec errors with that vendor. I didn't listen. A $6,800 order of rigid containers came back with the wrong closure threading. Completely unusable. That failure in March 2023 changed how I think about vendor qualification.
Before committing to a major vendor relationship:
- Send them a spec sheet with one deliberate ambiguity
- See if they catch it and ask for clarification
- Request a written confirmation of specifications before production
- Ask about their proof/sample process for custom work
Good vendors ask questions. They push back on specs that don't make sense. That friction upfront saves you from expensive mistakes later.
Step 5: Check Lead Time Consistency—Not Just Speed
A vendor who delivers in 14 days every time is more valuable than one who promises 7 days and delivers in "7 to... uh, maybe 21."
Ask for:
- Standard lead time for your product type
- Rush capability and what it costs
- Their on-time delivery rate (good vendors track this)
- What happens when they miss a deadline
That last question is telling. Some vendors have actual policies—credits, expedited reshipping, whatever. Others just say "we'll do our best." The difference matters when you've got a production line waiting.
Step 6: Verify Their Sustainability Claims
Per FTC Green Guides, environmental claims like "recyclable" must be substantiated. A product claimed as "recyclable" should be recyclable in areas where at least 60% of consumers have access. Source: FTC 16 CFR Part 260 (Green Guides).
If a packaging vendor claims:
- "Recyclable materials"—ask where and what certifications
- "Sustainable sourcing"—ask for chain of custody documentation
- "Reduced carbon footprint"—ask compared to what baseline
I'm not saying vendors lie. I'm saying some marketing teams get ahead of what's actually verifiable. Your compliance team will thank you for asking these questions upfront.
Step 7: Run a Pilot Order Before Volume Commitment
This was accurate as of Q4 2024. The packaging market changes fast, so verify current lead times and pricing before budgeting.
Even if you're confident, run a small order first:
- Pick a product that represents your typical needs
- Order enough to see their actual process (not their "special treatment for new customers" process)
- Track every touchpoint: order confirmation, production updates, shipping notification, delivery, invoice
When I took over purchasing in 2020, I inherited two vendors who'd been grandfathered in for years. Ran pilot orders with three alternatives. One was clearly better. One was about the same. One was a disaster. That $1,200 test saved us probably $15,000 in the first year.
Common Mistakes I Still See (And Have Made)
Choosing the vendor your predecessor used "because they've always used them." Maybe there's a good reason. Maybe there's inertia. Test it.
Assuming bigger vendors are always more reliable. Global scale and manufacturing network matters—Berry Global's reach is genuinely useful for multi-location companies. But a regional specialist might serve you better for specific product categories. Match vendor scale to your actual needs.
Forgetting that your contact person might leave. Evaluate the company's systems, not just your sales rep's responsiveness. What happens when Sarah goes on maternity leave or takes another job?
Not documenting why you chose a vendor. In 2024 vendor consolidation project, I had to explain decisions my predecessor made with zero documentation. Now I keep a one-page summary for every vendor relationship: why we chose them, what they're good at, what to watch out for.
My experience is based on about 400 orders over five years managing relationships with 8 vendors for different packaging needs. If you're working with specialty materials or extremely high volumes, your evaluation criteria might differ significantly. But the core principle holds: verify everything that matters to your specific operation before you commit.
