I manage purchasing for a mid-size company—about 300 employees across two locations. I place orders for packaging, tape, janitorial supplies, and the occasional odd request like foam inserts or custom containers. Roughly $250,000 annually across 8-10 vendors. I've been doing this since 2020, and I’ve made enough mistakes to have a system now.
This checklist is for other admin buyers or operations people who handle packaging and supply orders—not one-off purchases, but repeat, B2B-scale orders. If you’re consolidating vendors, onboarding a new supplier (like a dart container facility if it fits your network), or just tired of surprises on invoices, this is for you. Here’s my 5-step process. I use it for every new vendor relationship.
Step 1: Confirm the Vendor’s Operational Footprint
Before you even talk pricing, figure out where your orders will actually come from. I learned this the hard way in 2022. I assumed a vendor had a single national warehouse. Turns out, their “national coverage” meant they drop-shipped from 3 different facilities, and one of them was perpetually behind schedule.
What to verify:
- Do they have multiple plants or distribution centers? For example, if you’re looking at a packaging supplier with locations like Waxahachie, Corona, Leola, or Chicago, you might be able to split orders for faster delivery.
- Can they confirm which facility will fulfill your order before you place it?
- What’s their actual coverage radius? (Local vs. national vs. regional)
This matters most for bulky items—like corrugated boxes or industrial containers—where shipping costs can eat up any product savings. I’ve had quotes change by 25% just because the fulfillment location was 400 miles further than I assumed.
Step 2: Check the Spec Confirmation Process
This is the step most people rush. In packaging, a “standard” box size or “standard” tape grade isn’t universal. I once ordered duct tape from a new vendor—just standard industrial grade. What arrived was a thinner, less tacky product that wouldn't hold on our corrugated boxes. The vendor claimed it met “industry standards,” but there’s a difference between general-purpose and heavy-duty.
What I do now:
- Ask for a spec sheet or data sheet before any purchase.
- Clarify tolerances. For boxes: burst strength, edge crush test (ECT), flute type. For tapes: adhesion strength, backing thickness, temperature range.
- Request a sample—even if they charge for it upfront. I’ve found samples save headaches. A $20 sample fee beats a $2,000 restocking fee.
Example from my experience: In Q3 2024, a vendor quoted us on “standard shipping boxes.” I asked for the spec sheet. Their “standard” was a single-wall box with lower ECT than we needed. We caught it before the order. 5 minutes of asking saved us from boxes that would’ve crushed under weight.
Step 3: Verify Critical Order Information (Don’t Assume)
This is the step I’m most paranoid about. I’ve made this mistake three times, and I finally created a checklist for it. The most common errors I’ve seen:
- Shipping address is wrong. I once sent 500 boxes to our old office. The freight company couldn’t redirect. I paid $400 to have them re-delivered. The vendor’s invoice? Non-negotiable because “address provided by customer.”
- Product code / SKU mismatch. Duct tape—specifically, “duct tape isaac” or “buy duct tape” type searches—can have dozens of variants. One digit off in the SKU changes the adhesive type.
- Unit of measure confusion. “Pallet” vs. “case” vs. “each” on a quote can cost you. I’ve seen quotes where 1 pallet = 50 cases, but the buyer thought 1 pallet = 100 cases. Read the fine print.
My rule: Before hitting submit, I do a verbal confirmation via phone or internal chat with the vendor rep. Email is too easy to misread. I say: “I’m about to order [product A, quantity B, ship to C]. Can you confirm I’ve got it right?”
Step 4: Get Clear on Invoicing & Hidden Costs
Nothing makes you look bad to finance faster than an invoice that doesn’t match the quote. This is where vendor relationships fall apart. I’ve had a vendor who couldn't provide a proper invoice—handwritten receipt only. Finance rejected the expense report. I ate $1,200 out of the department budget.
What I check now:
- Do they provide an itemized invoice, or just a total?
- Are setup fees or tooling charges included? In packaging, die-cutting or custom print setup can be $50-200. Digital setup fees vary. Verify up front.
- What’s the minimum order quantity (MOQ)? If it’s higher than you need, you might be stuck with inventory.
- Rush fees: For packaging, rush orders for next-day can add 50-100%. Standard 2-3 day rush: 25-50%. Ask specifically.
I also ask for the order cancellation policy. Not all vendors allow cancellations after 24 hours. And check their lead time in writing. We’ve had suppliers say “2 weeks” but then add “depending on production schedule.” That’s not a lead time.
Step 5: Test the Vendor’s Support & Documentation
This is the step most people skip. You find out how good a vendor is when something goes wrong. I test this before committing to a large order.
My test:
- Send a simple question via phone or email. How quickly do they respond? What’s the tone?
- Ask about a reorder process. Some vendors require manual reorder forms. Others offer digital portals. For high-volume buyers, digital portals that reduce manual data entry are worth their weight in gold. I’ve seen vendors who allow online reordering cut our processing time from 40 minutes to under 10.
- Check if they offer order tracking. If they don’t, expect to waste time finding out where your shipment is.
Unexpected benefit: When I consolidated our packaging orders to a vendor with a solid digital system, I eliminated about 6 hours of manual data entry per month. That’s roughly 3 days per year saved. Not bad for a “non-critical” step.
Common Mistakes & Final Notes
If you’re evaluating a new vendor (including a dart container facility or any packaging supplier), don’t skip the spec confirmation. It’s the most common source of waste. A 12-point pre-order checklist—even a simple one written on a sticky note—can save you from $1,000+ in rework fees.
Here’s what I wish someone told me earlier:
- Don’t assume “standard” means the same thing across vendors.
- Always ask about shipping costs upfront. Packaging is heavy; freight costs can be significant.
- If you think the price is too low, ask why. There’s usually a hidden cost (lower quality, less support, shorter lead time).
This worked for us, but our situation is a mid-size B2B company with predictable ordering patterns. If you’re a seasonal business with demand spikes, or if you're dealing with international shipping, your mileage may vary. I can only speak to domestic operations. Things may have evolved since I built this checklist in 2023. Always verify current pricing and policies before committing.
