This checklist is for anyone responsible for bringing a new packaging supplier on board and making sure they can actually deliver: no invoice problems, no delivery surprises, no internal friction. I manage procurement for a mid-size CPG company, and after handling accounts with Amcor’s Miramar (FL) flexible packaging plant and their rigid plastics facility in Evansville (IN), I’ve boiled the process down to five steps. Roughly sequencing these will save time and a lot of headaches.
Step 1: Verify Their Invoicing Setup Before Anything Else
I can't stress this enough. In 2024, I found a great price on custom-printed stand-up pouches from a small vendor—$0.18 cheaper per unit than our Amcor Evansville contract. I ordered 5,000 units. They shipped perfectly. But their invoice was a handwritten receipt. Our finance team rejected the expense. I spent three weeks fighting that, and the $900 difference ate a chunk of my annual budget.
So, for Step 1: send the new vendor your company’s onboarding form. This should include your legal entity, remit-to address, and tax ID. Ask them if they can send a PDF invoice, an EDI 810, and integrate with your AP portal (like Coupa or SAP). Don't just assume they can. If they can't provide a proper PDF invoice with a purchase order number field, it's a red flag. Have them send a test invoice now—before you place any real orders. This is the single most common point of failure I see, especially when moving from a large established provider like Amcor Miramar to a smaller specialist.
Step 2: Establish the Communication Protocol (Who? How? When?)
Don't just take the general sales number. You need a named person. I manage relationships with roughly eight vendors. For critical packaging lines, like the ones supplied from Amcor’s Evansville plant, I know the account manager, the customer service rep, and the plant logistics coordinator. But I didn’t build that in a day.
For a new vendor, establish this:
- The order taker: The person who receives and processes your PO.
- The order fixer: The person you contact if the order is wrong or late.
- The payment fixer: The contact for accounts payable issues.
I'd argue this is more important than price. A vendor who can't route a simple question will make you look bad to your operations team. Set a weekly 15-minute call for the first month to review open orders. This stops problems before they happen. In my experience, the vendors who proactively set this up are the ones who last.
Step 3: Test the Ordering System with a Small, Low-Stakes PO
This gets into systems integration territory, which isn't my absolute expertise. What I can tell you from a procurement perspective is that you should not place a $50,000 order as your first test. Send a PO for a single item—something you stock anyway, like a standard roll stock film. Use the exact format your internal system generates (e.g., a standard ERP PO).
I'm not 100% sure why some systems glitch, but my best guess is it comes down to file format and field mapping. Have the vendor confirm they received the PO with all line items matching. Map the fields: buyer code, item number, quantity. A failure here is better discovered on a $200 test than a $20,000 one. That unreliable online print shop I worked with in 2023 cost me my VP's confidence when the material arrived with the wrong SKU coding. Don't let that be you.
Step 4: Define the Quality and Compliance Checkpoints
Before the big order, have a clear checklist of what “success” is. I don’t just mean “it’s the right color.” I mean:
- Physical specs: Gauge, seal strength, barrier properties (for flexible packaging like Amcor's films).
- Regulatory compliance: Per FDA or EU regulations. For instance, if you need to print “FDA approved for food contact” on the artwork, verify the regulation number they are following. As of mid-2024, we explicitly verify the CFR 21 section for indirect food additives with any new film supplier.
- Packaging and labeling: Tote weight, box quantity, label format. If your warehouse uses a specific scan system, the vendor's label must match. I'm not a logistics expert, so I can't speak to carrier optimization, but I can tell you from weeks of confusion that a mislabeled pallet costs $200 in warehouse labor to fix.
Passing this step is the green light for a full-scale purchase order. If you need samples, ask for them with the test order. The sample is the test order. Don't separate those stages.
Step 5: Consolidate and Automate (The Real Efficiency Gain)
Our company consolidated its vendor list from 12 to 6 in 2024. I had to standardize processes for those 6 vendors for operations across 3 locations. Using a simple digital order form template cut our ordering time from an average of 45 minutes per order to under 15 minutes, and nearly eliminated the PO entry error issue where numbers got transposed.
Once the first full order with the new vendor completes without a hitch (matching docs, on-time delivery, finance paid), ask them if they have a customer portal. If they do, get yourself and one backup person trained on it. This eliminates email-based order errors. The vendor who couldn't provide proper online access was dropped in our 2025 vendor consolidation project—it simply wasn't worth the manual tracking.
Common Errors & Final Reminders
- Don't skip Step 1 for smaller vendors. Larger companies like Amcor have standardized billing. Smaller shops may not. Verify their invoicing capability.
- The accounting team's happiness is your shield. If you make their job easy, they'll protect you from getting blamed for a late shipment. If you cause them $2,400 in rejected expenses like I did, you'll be on their radar forever.
- Roughly speaking, this whole process takes 4-6 weeks for a new, small vendor. A large established vendor like Amcor (Miramar or Evansville) can be set up in a week because the systems are proven. Adjust your expectations accordingly.
Prices as of December 2024 for standard film are for general reference. Verify current pricing and setup requirements directly with the vendor. This is a general guide from my experience; actual technical integrations—like EDI file mapping—may require your IT team's input.
