Protein Bar Contract Manufacturing: Deposits, MOQs, and Financing the Gap

This guide maps the cash mechanics of a co-man contract: MOQs, deposit and balance structures, ingredient prepays on volatile inputs like whey, and how purchase order financing sequences against each payment milestone. The numbers are ranges, not quotes. Your actual terms depend on formulation, packaging, and volume.

According to IMARC Group’s protein bar market report, the global protein bar market was valued at USD 3.93 billion in 2025 and is projected to reach USD 5.89 billion by 2034, a compound annual growth rate of 4.6%. That growth pulls more brands into national retail, and national retail runs on volume commitments most early brands are not capitalized to fund alone.

MOQ reality for protein bars

A minimum order quantity (MOQ) is the smallest run a co-manufacturer will accept. In our experience working with CPG founders, MOQs at established co-mans commonly fall in the 100,000 to 250,000 bar range per SKU. Smaller shops run pilot batches as low as 5,000 to 25,000 bars, but per-unit costs at those volumes are steep enough to wreck your margin on a retail order.

Bar lines run high because a bar is an assembled, multi-ingredient product: slurry gets mixed, formed or extruded, cut, enrobed, cooled, then wrapped and cased. Each step involves setup, sanitation, and changeover. A co-man loses money on a run too short to cover that overhead, so the minimum protects their margin, not punishes yours.

The upside of a high MOQ is unit economics: cost per bar drops as fixed setup spreads across more units. The downside is cash. A 150,000 bar run can tie up six figures before the retailer pays. That gap is what this article is about.

Deposit structures: where the cash actually goes

A deposit structure is how the co-manufacturer splits your payment across the production timeline. In the co-man contracts we see from CPG borrowers, the upfront deposit frequently runs 30% to 50% of the run cost. That money secures your calendar slot and funds the co-man’s early commitments to labor and materials.

1. Deposit at booking. You pay 30% to 50% to reserve line time. Many co-mans invoice this weeks before production, and the date is not guaranteed until it clears.
2. Balance on completion. The remaining balance comes due when the run finishes, often before goods release for pickup or shipment.
3. Net terms, if any. Established brands sometimes negotiate short net terms on the balance. First-time customers rarely get them.

Two details matter for cash planning. The deposit lands weeks before you produce anything, so cash leaves before the order generates a dollar. And the balance often gates release: the co-man holds finished goods until final payment clears, which means you cannot ship, invoice, or start the retailer’s payment clock until you have covered the full run.

Ingredient and whey prepays

An ingredient prepay is a separate payment the co-manufacturer requires to purchase volatile or long-lead raw materials before production, on top of the run deposit. Whey protein is the usual trigger. It is typically the single largest ingredient cost in a bar formulation, and its price swings with dairy markets outside anyone’s control.

Whey comes from cheese production and needs specialized processing before it becomes usable powder. When demand rises faster than supply, concentrate and isolate prices climb and stay firm, a pattern the USDA Agricultural Marketing Service’s Dairy Market News tracks weekly. A co-man will not carry that price risk. If whey has to be locked in at today’s price for a run eight weeks out, the co-man wants the ingredient money committed now.

The same logic applies to specialty coatings, functional additives, or custom packaging with its own minimums and lead times. For more on financing the raw material layer, see our guide to raw material and ingredient financing. The point here is timing: prepays stack on top of your deposit and pull cash forward even further.

How PO financing sequences with the co-man schedule

Purchase order financing funds supplier and production costs tied to an incoming retail order, paying your co-manufacturer directly instead of putting cash in your account. Its value is timing. A PO facility releases funds in tranches that match the co-man’s milestone schedule.

1. Ingredient prepay tranche. The facility funds the whey and long-lead input prepay so you do not front it from reserves.
2. Production deposit tranche. When the 30% to 50% deposit invoice arrives, the facility covers it, and your calendar slot holds.
3. Balance-on-completion tranche. When the run finishes and the balance gates release, the facility clears it so finished goods ship on schedule.
4. Repayment on retailer payment. After you deliver and the retailer pays, the facility is repaid from those proceeds. The remainder is yours.

The co-man’s payment schedule and the retailer’s payment schedule sit at opposite ends of a long gap. Major retailers like Walmart, Costco, and Kroger typically pay on Net 60 to Net 90 terms. Add production and shipping time, and the stretch from deposit to cash-in-hand can run several months. A facility built around the order absorbs that gap without a daily debit against your operating account.

Inventory facility vs PO facility for the build

Both structures can fund a production build, but they solve different problems. The right choice depends on whether you are funding a specific incoming order or building stock ahead of demand.

Use purchase order financing when you have a specific order. The facility underwrites the retailer’s credit, not just your balance sheet, which is why growth-stage brands often qualify when a bank line is out of reach. It pays the co-man directly and clears on the retailer’s payment.

Use inventory financing when you are building stock against forecast demand, for example pre-building safety stock ahead of a promotional window. It advances against inventory you own, and you control how the cash gets deployed. For a deeper decision framework, see our guide to inventory financing for CPG builds. Many bar brands use both across a season: inventory financing to pre-build, then PO financing when an incoming order lands.

FAQs

What is a typical MOQ for a protein bar contract manufacturer?

At established co-manufacturers, protein bar MOQs commonly land in the 100,000 to 250,000 bar range per SKU. Each run involves setup, sanitation, and changeover costs that a short run cannot absorb profitably. Smaller co-mans offer pilot runs as low as 5,000 to 25,000 bars, but at a much higher cost per unit.

How much deposit do co-manufacturers require?

Based on the co-man contracts we review from CPG borrowers, food co-manufacturers frequently require 30% to 50% of the run cost upfront, with the balance due at or shortly after completion. The deposit usually lands weeks before production begins. Established brands sometimes negotiate short net terms on the balance, but first-time customers rarely do.

Why do co-mans require ingredient prepays on whey?

Whey protein is typically the largest single ingredient cost in bar formulations, and its price swings with dairy markets. Because whey comes from cheese production and requires specialized processing, tight supply keeps prices volatile. A co-manufacturer will not carry that price risk, so it requires the ingredient money committed before locking in a purchase for a future run.

Can PO financing cover both the deposit and the balance?

Yes. A purchase order facility can release funds in tranches matched to the co-manufacturer’s schedule: an ingredient prepay tranche, a production deposit tranche, and a balance-on-completion tranche. Repayment comes from the retailer’s payment after delivery, so the financing spans the full gap from deposit to cash-in-hand.

Is PO financing or inventory financing better for a production run?

Purchase order financing fits when you have a specific incoming retail order, because it underwrites the retailer’s creditworthiness and pays the co-man directly. Inventory financing fits when you are building stock ahead of forecast demand, because it advances against inventory you own. Many brands use both across a selling season.

Fund the production build against your Walmart order

The deposit, the ingredient prepay, and the balance all come due before your retailer pays. Bridge is a direct lender for Walmart-focused purchase order financing, and the program also supports Sam’s Club suppliers. We fund up to 100% of cost of goods sold on approved transactions, paying your co-manufacturer directly so production starts on schedule. Repayment is aligned with the retailer’s payment cycle, subject to underwriting, so financing tranches sequence against your co-man’s milestones instead of fighting them.

If you have an upcoming Walmart order, buy plan, or buyer commitment and a co-man contract to fund, request financing to see if your order qualifies. Bridge is the official financing partner of Walmart’s Purchase Order Financing Program.
