The biggest co-packing mistake
new brands make —
and how to avoid it.

We've seen it happen more times than we can count. A founder has a great product — real, differentiated, genuinely good. They find a co-packer willing to run it. The co-packer has minimums. Big ones. So the founder orders 50,000 units to get the per-unit cost down, commits to raw materials to fill them, and launches.

Six months later, half that inventory is sitting in a warehouse. The formula needed tweaking. The channel they planned for didn't pan out. The flavor that tested well with friends didn't move at retail. And now there's a six-figure inventory problem sitting between them and any ability to pivot.

This is the most common way early-stage supplement and food brands die. Not from bad products. From too much product, too soon.

Why co-packers push large minimums

Let's be honest about what's happening on the other side of that negotiation. Large minimum order quantities benefit the co-packer, not the brand. Here's why:

• 01
  Machine economics. A production run has fixed costs regardless of how many units come off the line — setup, labor, facility overhead, changeover time. The more units per run, the lower the cost per unit to the facility. Minimums protect their margin.
• 02
  Relationship leverage. Once you've ordered 50,000 units and committed to the raw materials to fill them, you're locked in. You can't easily switch co-packers. You can't easily change your formula. The large minimum creates dependency.
• 03
  PE ownership incentives. Many large co-packers are private equity owned. PE-backed businesses are optimized for revenue and margin, not for whether your brand survives the process. They don't make money when you prove a concept on 3,000 units — they make money when you're committed to 50,000.

None of this is necessarily malicious. It's just that their incentives are not aligned with yours, especially in the early stages. Knowing that changes how you should approach the conversation.

What "proving your concept" actually means

Proving your concept doesn't mean making a few hundred units by hand in a commercial kitchen. It means running a real production run — professionally filled, properly sealed, in your actual packaging — and putting it in front of real buyers or real customers in your actual channel.

That might be 2,000 units for a DTC test. It might be 5,000 for a regional retail pitch. It might be 8,000 for an Amazon launch. What it almost never needs to be is 50,000 units before you know if the product moves.

Specifically, here's what you're trying to learn before you scale:

• 01
  Does the formula taste and perform the way you expect at scale? Things change when you go from hand-mixed batches to machine-filled production runs. Fill weight consistency, powder flow, and flavor profile can all shift. You want to discover that on 3,000 units, not 50,000.
• 02
  Does the channel actually work? Amazon ranking, retail buyer interest, DTC conversion — none of these are guaranteed. A small run lets you test before you're sitting on a warehouse full of product you can't sell.
• 03
  Is this the right flavor / format / size? Consumer feedback on a real product in real packaging is more valuable than any focus group. A small run lets you iterate. A 50,000-unit commitment makes iteration extremely expensive.
• 04
  What is your actual velocity? How fast does the product sell in your channel? That number determines your reorder cadence and your next run size. You can't know it until you've actually sold something.

The math that nobody shows you

Co-packers will show you the per-unit cost at 50,000 units versus 5,000 units. It looks compelling. At 5,000 units, your per-unit packaging cost might be $0.80. At 50,000, it drops to $0.35. That's real.

What they don't show you is the total cost of being wrong.

If you order 50,000 units and 30,000 sit in a warehouse for 18 months — factoring in raw materials, packaging, storage, and capital cost — the "savings" on per-unit packaging cost disappear fast. The brands that survive are the ones that optimize for total cost of learning, not per-unit cost of production.

A $3,500 production day for 5,000 units is expensive per unit. It is also an extremely cheap way to find out if your product and channel work before you bet real money on them.

How to actually scale — the right sequence

Here's the sequence that works for most supplement and food brands:

• 01
  Small proof-of-concept run (2,000–5,000 units). Get a real production run in your actual packaging. Test the formula at scale. Launch in your primary channel. Learn what happens.
• 02
  Iterate if needed. Formula tweak, flavor adjustment, packaging change — whatever the market tells you. This is cheap at 5,000 units. It is catastrophic at 50,000.
• 03
  Validate velocity. Once you know the product works and the channel works, you have real sell-through data. Now you know what your reorder cadence looks like and you can plan production runs accordingly.
• 04
  Scale with confidence. Now a larger run makes sense — because you know what you're selling, to whom, at what rate. The per-unit savings on a 20,000-unit run are real when you know 20,000 units will actually sell.

What to ask any co-packer before you commit

Whether you work with Overgang or someone else, here are the questions to ask before signing anything:

On minimums:

What is your actual minimum run? What happens if I want to run less? Is there a penalty? Get this in writing.

On pricing:

What is the all-in cost per production run? Are there setup fees, changeover fees, or minimum unit charges on top of the quoted price? Ask for a sample invoice from a previous customer if they'll share one.

On flexibility:

Can I change my formula between runs? Can I change my packaging? What's the lead time and cost if I need to make adjustments?

On what happens when something goes wrong:

This is the question nobody asks until it's too late. What is your policy if there's a fill weight error? A contamination issue? A run that doesn't meet spec? How have you handled it in the past? The answer to this question tells you everything about whether a co-packer actually has your interests in mind.

A good co-packer will answer these questions directly and without defensiveness. A bad one will get vague, redirect to the contract, or tell you it's never been an issue. That vagueness is the warning sign.

The bottom line

The brands that make it are the ones that stay lean until they know something is working. Every dollar you don't spend on inventory you can't sell is a dollar you can spend on the run that proves your concept, the marketing that drives your first sales, or the formula adjustment that unlocks your market.

Scale it. Prove it. Move it. In that order.

And find a co-packer whose incentives are aligned with that sequence — not one who makes more money when you're locked into a commitment you're not ready for.
