Custom Manufacturing vs Contract Manufacturing: What CPG Founders Need to Know

The Most Misunderstood Decision in Product Development

If you're launching a beauty or CPG brand, you've probably encountered these terms: custom manufacturing, contract manufacturing, private label, white label, co-packing, toll manufacturing.

They're often used interchangeably. They shouldn't be.

The difference between these approaches determines whether you own your formulas, how differentiated your products can be, what your margins look like, and whether you can ever switch manufacturers without starting over.

This guide cuts through the confusion. By the end, you'll know exactly which approach fits your brand—and the questions to ask before you sign anything.

Definitions: What These Terms Actually Mean

Let's start with clear definitions, because the industry uses these terms loosely.

Contract Manufacturing (CM)

Definition: A third-party manufacturer produces products according to your specifications, under your brand name.

Key characteristics:

• You provide the formula (or they develop it for you)
• They handle production, filling, and packaging
• You own the finished goods
• IP ownership varies by agreement (this is critical)

Also called: Contract manufacturer, CM, third-party manufacturer

Custom Manufacturing

Definition: A type of contract manufacturing where the formula is developed specifically for your brand, from scratch.

Key characteristics:

• Unique formula created for you
• Significant R&D investment
• Full product differentiation
• IP ownership typically included (but verify!)

The key difference: Custom manufacturing is a subset of contract manufacturing—it specifically refers to developing new formulas, not just producing them.

Private Label

Definition: Pre-made, stock formulas that you purchase and sell under your own brand name.

Key characteristics:

• Formula already exists (you didn't develop it)
• Minimal to no customization
• Fast time to market
• Low development costs
• You do NOT own the formula IP

Also called: White label, stock formula, off-the-shelf

Toll Manufacturing

Definition: You provide the complete formula and all raw materials; they only provide labor and equipment.

Key characteristics:

• Maximum control over formula
• You source all ingredients
• Lower per-unit cost (no material markup)
• Higher operational complexity
• Full IP ownership (you created it)

Co-Packing

Definition: Packaging and assembly of finished products (often used for food/beverage).

Key characteristics:

• Product is already manufactured
• They handle filling, labeling, packaging, kitting
• Common in food/beverage, supplements
• Sometimes combined with manufacturing

The Comparison Matrix

Here's how these approaches stack up across the factors that matter:

---

The IP Question: Why Formula Ownership Matters

This is the single most important factor most founders overlook.

The Scenario

You launch with a contract manufacturer. Your product takes off. Sales grow 300% year over year. Then:

• Your CM raises prices 40%
• Lead times slip from 4 weeks to 12 weeks
• Quality becomes inconsistent
• You want to switch manufacturers

If you don't own your formula: You can't take it anywhere. Your CM owns it. You either stay (and accept their terms) or start over with a new formula—which your customers may not recognize or accept.

If you own your formula: You thank them for their service, take your formula documentation, and move to a new manufacturer. Your products stay identical. Your customers never know the difference.

How to Verify Formula Ownership

Don't assume. Check these three things:

1. Master Services Agreement (MSA) Look for language like:

• "All formulations developed shall be the exclusive property of [Your Company]"
• "Client retains all intellectual property rights"

Red flag language:

• "Formulas are proprietary to [Manufacturer]"
• "Client receives a license to use formulas"
• "Formulas may not be disclosed to third parties"

2. Formula Documentation You should receive:

• Complete INCI ingredient list with percentages
• Manufacturing instructions (batch procedure)
• Raw material specifications
• Stability testing data

If they won't provide percentages or procedures, you don't own the formula.

3. Transfer Rights Explicitly confirm:

• "Can I take this formula to another manufacturer?"
• "Will you provide batch records if we part ways?"
• "Is there a fee to transfer the formula?"

When to Choose Each Approach

Choose Private Label When:

✅ You're testing market demand before investing heavily ✅ Speed to market is critical (launching in weeks, not months) ✅ You're building audience before building product (influencer launches) ✅ Your differentiation is in branding/marketing, not formula ✅ Budget is extremely limited (<$5,000 total)

❌ Avoid if: You want long-term brand equity, plan to sell the business, or need product differentiation

Choose Contract Manufacturing (Their Formula) When:

✅ You want some customization (fragrance, color, minor adjustments) ✅ Speed matters but you want slight differentiation ✅ You're okay being somewhat dependent on this manufacturer ✅ Budget is limited but you want better quality than pure private label

❌ Avoid if: IP ownership is important, you anticipate switching manufacturers, or product uniqueness is part of your brand story

Choose Custom Manufacturing When:

✅ You're building a brand for the long term ✅ Product differentiation is part of your value proposition ✅ You want to own your formulas outright ✅ You may sell the business someday (IP matters for valuation) ✅ You have specific claims or performance requirements

❌ Avoid if: You need to launch immediately or have very limited capital

Choose Toll Manufacturing When:

✅ You already developed the formula (or have a chemist) ✅ You want maximum cost efficiency at scale ✅ You prefer to source your own ingredients ✅ You're producing high volumes (10,000+ units) ✅ You have operational capacity to manage suppliers

❌ Avoid if: You're new to manufacturing, want turnkey solutions, or lack supply chain expertise

The Hidden Costs of Each Approach

Beyond the obvious pricing, each approach has hidden costs:

Private Label Hidden Costs

• Rebranding later: When you switch to custom, your product changes—customers may not follow
• Margin compression: Everyone has access to the same products; price competition is fierce
• No moat: Competitors can offer identical products

Contract Manufacturing Hidden Costs

• Switching costs: If you don't own the formula, switching means reformulating
• Relationship dependency: Your business is tied to their capacity, quality, and pricing
• Limited leverage: They know you can't easily leave

Custom Manufacturing Hidden Costs

• Time investment: 8-16 weeks to develop, iterate, and finalize formulas
• R&D fees: $2,000-10,000+ for formula development (though platforms like Genie eliminate this)
• Testing requirements: Stability, micro, challenge testing ($1,500-4,000)
• Iteration cycles: Multiple sample rounds before you get it right

Toll Manufacturing Hidden Costs

• Operational complexity: You're managing ingredient suppliers + manufacturer
• Inventory risk: You own raw materials; if formula changes, you're stuck with inventory
• Quality variability: Different ingredient lots can affect consistency
• Minimum scale: Most toll manufacturers only work at high volumes

How to Evaluate a Contract Manufacturer

Whether you choose custom or contract manufacturing, vet your manufacturing partner carefully:

Non-Negotiable Requirements

1. Certifications and Compliance

• FDA registered facility
• GMP (Good Manufacturing Practice) certified
• Relevant category certifications (organic, cruelty-free, etc.)

2. Insurance

• Product liability insurance ($1M+ per occurrence)
• General liability
• Willingness to add you as additional insured

3. Documentation

• Certificate of Analysis (COA) for each batch
• Batch records and traceability
• Stability testing protocols

Due Diligence Questions

About Their Business:

1. How long have you been in business?
2. What brands do you work with? (Ask for references)
3. What's your specialty? (Some focus on skincare, some on color, etc.)
4. What percentage of your capacity is currently utilized?

About Production: 5. What's your typical lead time? 6. What happens if you miss a delivery date? 7. How do you handle quality issues or rejects? 8. What's your batch failure rate?

About IP: 9. Who owns the formulas you develop? 10. Can I take my formula elsewhere if we part ways? 11. What documentation will I receive? 12. Is there a formula transfer fee?

About Pricing: 13. What's included in your per-unit quote? 14. Are there setup fees? Per SKU or per order? 15. How does pricing change at higher volumes? 16. What's not included that I should budget for?

Making the Decision

Here's a simple framework for choosing your approach:

If you answer YES to most of these, go Custom:

• I'm building this brand for 5+ years
• My product story includes what's in the product, not just branding
• I might sell this business someday
• I want flexibility to switch manufacturers
• I have specific performance claims or ingredient requirements

If you answer YES to most of these, go Private Label (for now):

• I need to launch in the next 30 days
• I'm testing if there's demand for this product category
• My total budget is under $5,000
• My differentiation is my audience/brand, not the product itself
• I'm okay transitioning to custom formulas later

If you answer YES to most of these, go Toll:

• I already have formulas developed
• I'm producing 10,000+ units per order
• I have supply chain management experience
• I want the lowest possible per-unit cost
• I can manage multiple vendor relationships

Key Takeaways

1. Contract manufacturing and custom manufacturing aren't the same thing. Contract manufacturing is who makes your product. Custom manufacturing is whether they made the formula specifically for you.

2. Formula ownership is the most important decision. It affects your ability to switch manufacturers, your company valuation, and your long-term leverage.

3. Private label is fine for validation—not for building. Use it to test demand, then invest in custom formulas for products that work.

4. Ask the IP questions before you sign. Assume nothing. Get formula ownership in writing. Verify you'll receive full documentation.

5. Platforms like Genie change the equation. Custom formulation no longer requires $5,000 R&D fees and 3-month timelines.
