Why Most Packaging RFPs Miss the Real Cost (And How to Fix It)

Stop chasing the lowest unit price on your packaging RFPs

After 6 years and about 180 purchase orders tracking every dollar our mid-size manufacturing company spent on packaging, I can tell you the single biggest mistake buyers make: they optimize for the wrong metric. Unit price is not total cost. And total cost—including shipping, setup fees, minimum order quantities, and quality-related rework—is what hits your P&L.

I manage a roughly $80,000 annual packaging budget across corrugated boxes, folding cartons, shoe boxes, and some specialty wine packaging. Over the years, I've built a cost-tracking spreadsheet that logs every quote, every invoice, and every "surprise" fee. It has fundamentally changed how I evaluate suppliers—and it might change how you do, too.

What my data revealed about packaging sourcing

In Q1 2024, I did a deep dive comparing 8 vendors for a recurring order of custom-printed folding boxes. The raw quotes ranged from $0.52 per unit to $0.84 per unit. Easy choice, right? The $0.52 vendor. Except when I added in their setup fee ($180), their standard shipping ($220 per order for our location), and the fact that their minimum order quantity was 2,000 units vs. a competitor's 500 units—the picture changed. The $0.52 vendor's total annual cost for our needs was $4,800 (including overstock we couldn't use). The $0.84 vendor's total was $4,500. That's a 6.25% savings by choosing the "expensive" vendor.

It took me about 3 years and maybe 150 orders to really understand this. At first, I thought it was about negotiating the lowest unit price. Now, I know it's about evaluating the entire cost structure. Here's something vendors won't tell you: the first quote often has hidden variables they assume won't apply to you... but they do.

The four hidden cost drivers I track

• Setup and tooling: One folding box manufacturer quoted a $0.63 unit price but had a $350 setup fee. A competitor at $0.71 had no setup fee. For a 500-unit order, the difference was $315 vs. $355 total—pretty close. For a 5,000-unit order, setup becomes almost negligible.
• Shipping by weight vs. volume: This sounds small, but I've seen it add 12-18% to an order. For wholesale packaging supplies like corrugated cases, shipping often costs more than the boxes themselves. Always ask: is shipping flat-rate or dimensional-weight?
• Minimum order quantities (MOQs): A paper bag supplier might offer a great unit price—but only if you buy 10,000 bags. If your actual need is 3,000, you'll either overstock (cash tied up in inventory) or pay a "short-run" penalty that can add 25% to the unit cost.
• Rush fees and versioning: Need one custom color on your shoe box vs. the standard? That's an extra $0.04 per unit? Not always. Some vendors charge an entirely different rate for non-standard spec. I once paid $450 extra because I didn't specify "standard" vs. "premium" board stock.

How to build your own vendor scorecard

I use a simple spreadsheet. For every potential supplier, I collect:

• Unit price (for our actual quantity, not the reference MOQ)
• Setup costs per order (and if they waive them after X orders)
• Shipping cost estimate (get a real quote, not a calculator)
• Past quality issues (track these! I keep a log)
• Payment terms (Net 30 vs. Net 60 affects cash flow)

I run this for every RFP that's over $2,000 now. It takes about 1 hour per vendor, but I've consistently found that choosing the lowest TCO vendor saves 8-15% compared to just going with the lowest unit price. Put another way: I've saved roughly $8,000 annually by doing this analysis—money that would have been lost in "inexpensive" packaging that wasn't actually cheap.

A real-world example with rigid boxes

Last year, I bid out a luxury rigid boxes program for our premium wine packaging line. Three vendors. Vendor A quoted $1.12 per box with free setup. Vendor B quoted $0.98 per box plus $220 setup. Vendor C quoted $1.18 per box, all-inclusive, but with a 30-day lead time vs. 15 days. A quick TCO analysis: Vendor A's total for 1,200 boxes was $1,344. Vendor B: $1,396 (the setup fee ate the unit price advantage). Vendor C: $1,416. Seemed clear, right? Except I factored in our cash flow timing—Vendor A offered Net 60, while B and C were Net 30. That moved Vendor A from "lower cost" to "almost clearly better" for us. But Vendor C's longer lead time meant we'd need to order earlier, which changed our inventory holding costs. In the end, Vendor A won because their combination of low TCO and favorable payment terms fit our operational model.

When the lowest quote is the best choice

I'm not saying the cheapest is never the answer. For commodity items—like standard corrugated shipping boxes where specs are identical across suppliers—the lowest price is probably fine. But as soon as there's any customization, any setup, any printing, or any specialty material? You need the full picture. To be fair, many procurement folks don't have time to do this deep dive for every purchase. I get it. For orders under $500? Don't bother. For orders over $2,000? Invest the hour. It pays off.

Granted, my approach has limits. I'm tracking data for a mid-size manufacturer. If you're a one-person operation ordering 100 shoe boxes, vendor relationships work differently. A big supplier like Greif offers global networks and product breadth—but if you only need a small run, their minimums might not fit. That's not their fault; it's your scale. The key is awareness: understand what drives your actual cost, and choose a supplier whose model aligns with your needs.

So next time you get a quote for packaging, ask yourself one question before signing: what am I not being quoted? Because whatever it is, that's where the real cost lives.
