The True Cost of Co-Manufacturing: Hidden Fees to Watch For

When a co-manufacturer quotes you $2.80 per unit, that number feels concrete and comparable. You can plug it into your margin model, compare it against other co-mans, and decide whether the economics work. But that per-unit price is rarely the full story. By the time you factor in setup fees, changeover charges, waste allowances, storage costs, and a half-dozen other line items, your true per-unit cost might be $3.40 or higher.

The gap between the quoted price and the actual cost is where CPG margins quietly erode. Understanding these hidden costs is not just about saving money — it is about making accurate financial decisions about pricing, channel strategy, and whether co-manufacturing is even the right model for your brand long-term.

The Cost Components Beyond Per-Unit Price

Setup and Changeover Fees

Every time the co-man runs your product, they need to set up the line. This includes cleaning equipment from the previous run (especially critical for allergen management), calibrating machinery for your specifications, and loading your packaging materials. Setup fees typically range from $500 to $3,000 per run, depending on the complexity of your product and the size of the facility.

If you are running small batches — say 5,000 units per run — a $2,000 setup fee adds $0.40 per unit. Run 50,000 units and that same fee is only $0.04 per unit. This is why minimum order quantities exist: they protect the co-man from losing money on setup for tiny runs, and they should inform your production planning.

Minimum Order Quantities and Overrun Charges

Most co-mans set MOQs that reflect their breakeven point on a production run. If their MOQ is 10,000 units and you only need 6,000, you are either paying for 10,000 or paying a short-run premium. Some co-mans will accommodate smaller runs at a 15-30% markup on the per-unit price, while others simply will not run below their minimum.

On the other end, overruns are common. A co-man might produce 3-5% more than the ordered quantity to ensure they hit the target after accounting for quality rejects. You will typically be charged for these overrun units. Make sure your contract specifies the acceptable overrun percentage and whether you are obligated to purchase excess production.

Waste and Shrinkage Allowances

Every production run generates some waste — product that does not meet spec, packaging that gets damaged during filling, and raw materials lost during startup and shutdown. Co-mans handle this differently. Some build a waste allowance into their per-unit price (typically 2-5%), while others charge you for raw materials consumed regardless of how many finished units are produced.

Always ask how waste is accounted for in your co-man agreement. If you are supplying your own raw materials, a 5% waste rate on a $100,000 ingredient order is $5,000 of product that never made it into a sellable unit.

Storage and Warehousing Fees

Your co-man is not a free warehouse. If finished goods sit at the facility for more than a few days after production, most co-mans charge pallet storage fees ranging from $15 to $40 per pallet per month. Similarly, if you ship raw materials or packaging to the co-man weeks before a scheduled run, you may be charged for inbound storage.

These fees add up quickly if your logistics are not tightly coordinated. A brand holding 200 pallets at a co-man for three weeks beyond the production date could easily incur $1,500 to $4,000 in unplanned storage charges.

R&D and Trial Run Costs

Before your first commercial production run, most co-mans require one or more trial runs to validate the recipe, dial in equipment settings, and ensure quality standards are met. These runs are not free. Expect to pay for the ingredient costs, labor, and a reduced setup fee. Depending on the complexity of your product, R&D runs can cost $3,000 to $15,000 — and you may need two or three before the co-man is comfortable running at full scale.

Certification and Compliance Costs

If your product requires specific certifications — organic, kosher, non-GMO, gluten-free — the co-man may pass through the cost of maintaining those certifications or charge a premium for certified production lines. Some facilities charge a flat annual fee for organic certification maintenance, while others build it into the per-unit price. Either way, understand exactly what you are paying for.

Calculating Your True Per-Unit Cost

To understand what your product actually costs to produce through a co-man, you need to tally every production-related expense over a defined period (usually a quarter or a year) and divide by the total units produced. Here is a framework:

Base production cost: Per-unit price multiplied by total units produced
Setup and changeover fees: Total fees across all production runs in the period
Waste and shrinkage: Value of raw materials consumed but not converted to sellable product
Storage fees: All warehousing charges at the co-man facility
Overrun charges: Cost of excess units produced beyond your order
R&D and trial costs: Amortized over the first year of production
Freight to co-man: Inbound shipping of raw materials and packaging
Freight from co-man: Outbound shipping of finished goods to your warehouse or 3PL

Divide the total by units produced, and you have your fully loaded per-unit cost. This is the number that belongs in your margin model — not the quoted price on your co-man agreement.

Negotiating Better Terms

Co-man contracts are more negotiable than most emerging brands realize. Once you understand the full cost structure, you have leverage to push on specific line items:

Volume commitments for lower per-unit pricing: If you can guarantee a minimum annual volume, many co-mans will reduce their per-unit price by 5-10%.
Consolidated production runs: Reducing the number of runs per year (larger batches, fewer setups) saves on changeover fees and often improves per-unit economics.
Shared waste risk: Negotiate a waste cap — for example, the co-man absorbs waste up to 3%, and anything above that is split 50/50.
Free storage windows: Many co-mans will offer 7 to 14 days of free storage post-production. Get this in writing.
Payment terms: Net-30 is standard, but some co-mans will offer net-45 or net-60 for established relationships. Better payment terms directly improve your working capital position.

Red Flags in Co-Man Contracts

Not all co-man agreements are structured fairly. Watch for these warning signs:

Exclusivity clauses that prevent you from working with other co-mans or bringing production in-house without a lengthy notice period
Automatic price escalation tied to vague cost increase justifications rather than specific indices like CPI or commodity benchmarks
No quality guarantee or remediation process for production defects — if they produce off-spec product, who pays?
IP ownership ambiguity around recipes, processes, or formulations developed during the relationship
No cap on ancillary fees for storage, overruns, or administrative charges

When to Consider Bringing Manufacturing In-House

In-house manufacturing is a major capital investment, but for some brands it makes financial sense once volume reaches a certain threshold. The general inflection point is when your annual production spending with co-mans exceeds $500,000 to $1 million and your product complexity is low enough to operate with a small team.

Before making the leap, model the full cost of in-house production: equipment, facility lease, labor, insurance, certifications, utilities, maintenance, and quality control. Compare the fully loaded in-house cost per unit against your fully loaded co-man cost per unit. If the in-house number is 15% or more lower and you have the capital to fund the transition, it is worth serious consideration. Below that threshold, the operational complexity of running your own facility usually is not worth the marginal savings.

Understanding the true cost of co-manufacturing is one of the most impactful financial exercises a CPG brand can undertake. It informs your pricing, your margin expectations, your channel strategy, and ultimately your path to profitability. Do not let an artificially low per-unit quote mask the real cost of getting your product made.
