Co-Manufacturer or Your Own Line? The Decision Most Food Brands Get Backwards

We get two kinds of calls about this. The first is a pre-revenue founder who wants to build a plant because owning production feels like owning the business. The second is a $15M brand still paying a co-manufacturer 30% margin on every case, wondering why they can't get ahead. Both are asking the same question at the wrong time — and usually in the wrong direction.

Here's how we'd think about it if we were sitting on your side of the table.

Start with what each option actually is

A co-manufacturer sells you variable cost and no capital. You pay per case, they own the equipment, the labor, the food-safety program, the downtime, and the headaches. In exchange you give up margin, control over your schedule, and — critically — the ability to make anything their equipment can't.

Your own line sells you fixed cost and control. The equipment is yours, so is the margin, so is every 2 AM breakdown. Your cost per case drops as volume rises and rises as volume falls. And you can make whatever you can engineer.

Neither is better. They're priced for different stages, and the mistake is almost always a stage mismatch.

The build-too-early trap

Pre-revenue brands build because it feels like progress and because investors can see a plant. But a production line is a fixed cost with a utilization requirement. A $600K line that needs 60% utilization to hit its cost-per-case target is a liability at 15% utilization — which is where most new brands sit for the first two years. The line eats cash while you're still learning what sells.

There's a second, quieter cost: you freeze the product before you've finished inventing it. A brand at kitchen scale changes formulation, format, and pack size constantly — that's how it finds the version the market wants. Equipment locks all of that. We've seen brands spend six figures on a line built for a 4 oz cup, then discover the 12 oz sells three to one.

If you're pre-revenue or under about $2–3M in sales, the answer is almost always a co-manufacturer. Use the margin you're giving up as tuition.

The outsource-too-late trap

The opposite failure is subtler. A brand grows to $10M, $20M, $40M and keeps co-manufacturing because it's working. Meanwhile:

• The co-man's margin — often 25–35% of COGS — is now the single largest cost line in the business.
• Your products are constrained to their equipment. Every innovation is a negotiation.
• Your schedule is their schedule. Peak season, you're in a queue.
• Your process knowledge is theirs. If they raise prices or exit the category, you're starting over.

At that scale, the capital for a line is often less than two years of co-man margin. The math has flipped and nobody re-ran it.

The question that settles it

Strip away the emotion and there's one calculation: at your realistic volume over the next three years, what is your cost per case each way — including the cost of being wrong?

For the co-man side, that's straightforward: their price plus your freight and QA overhead.

For the own-line side, it's harder and people fake it. You need: equipment and installation (get a real number, not a vendor's brochure); facility, utilities, and permitting; labor at a realistic crewing level; maintenance and spares (budget 3–5% of equipment value per year — more for washdown environments); food-safety program and certification; and utilization risk — what happens to cost per case if volume comes in 40% under plan. Most models skip that last one, and it's the one that closes plants.

When you run this honestly, the crossover for most food categories lands somewhere between $5M and $15M in annual sales, depending on how equipment-intensive the product is. Below it, co-manufacture. Above it, the line usually pays — if you can staff it.

The middle path most brands miss

This isn't binary. Three hybrids are worth knowing:

• Own the unique step, outsource the rest. If your product has one process nobody else can do — a novel fill, a proprietary cook, an unusual form — build that machine and place it in a co-manufacturer's plant. You own the moat; they own the boring parts. We've built exactly this arrangement, and it's often the highest-return option available.
• Toll manufacturing. You buy the equipment; a co-man runs it in their facility for a per-case fee. Lower capital exposure than a plant, more control than pure co-man.
• Buy used, start small. A first line built around used and modified equipment can come in at a third of new. It won't be pretty and it won't be your forever line — but it's a real line, and it's reversible.

Signs you're at the crossover

You're probably ready to bring production in-house when at least three of these are true: sales above roughly $5M and growing; a product or format your co-man can't or won't run; co-man cost is your largest single line item and you've re-quoted it in the last year; you have — or can hire — someone who has actually run a plant; and you can fund the line without betting the company on year-one utilization.

If fewer than three are true, stay with your co-manufacturer and put the energy into selling more. That's not a failure. It's the right stage.
