Selecting a third-party logistics partner is one of the most consequential operational decisions a brand can make.

Yet most 3PL proposal comparisons break down for one simple reason:

They are not structured to be compared.

Different rate formats. Different assumptions. Different definitions of scope. Different ways of calculating costs.

If you are evaluating multiple 3PL proposals, you do not need more spreadsheets.
You need a framework.

Below is a simple, structured approach for comparing 3PL proposals in a way that surfaces long-term fit—not just the lowest price.

Why Comparing 3PL Proposals Is So Difficult

When brands issue a fulfillment RFP, they typically receive:

• Rate cards with different fee structures
• Inconsistent assumptions around order volume and SKU count
• Varying definitions of value-added services
• Different carrier discount models
• Divergent onboarding timelines

Even sophisticated operators struggle to normalize proposals across providers.

The result?
Teams debate line items instead of evaluating operational fit.

A better approach starts with structure.

The 5-Part Framework for Comparing 3PL Proposals

Instead of starting with pricing, evaluate proposals across five consistent dimensions.

1. Scope Alignment: Are We Comparing the Same Thing?

Before reviewing rates, confirm that each 3PL is pricing the same scope.

Validate:

• Monthly order volume assumptions
• Average units per order
• SKU count and velocity mix
• Storage profile (pallet, bin, case)
• Returns handling assumptions
• Value-added services (kitting, labeling, subscription builds)
• Channel mix (DTC, wholesale, retail routing guide compliance)

If assumptions vary, the pricing will vary.

Most “low bids” simply reflect narrower assumptions.

Key question:
Did every 3PL quote against a standardized data set?

2. Cost Structure: What Drives Total Cost Per Order?

Rather than debating pick fees alone, model the total cost per order (CPO).

Break pricing into categories:

• Inbound receiving
• Storage
• Pick and pack
• Packaging materials
• Returns processing
• Value-added services
• Account management / tech fees
• Accessorials

Normalize all proposals into:

Projected monthly cost at stated volume
Projected cost per order (CPO)

This removes emotional debate over individual line items and centers the conversation around total economic impact.

A $0.10 difference in pick fee often matters less than storage methodology or returns complexity.

3. Operational Capability: Can They Actually Support Your Model?

A proposal can look clean on paper and fail in practice.

Evaluate:

• Multi-node footprint alignment with your customer geography
• OMS / WMS integration capabilities
• EDI capability for wholesale
• International shipping support
• Peak season capacity
• SLA structure and reporting cadence
• Inventory accuracy thresholds

This is where many brands optimize for cost but underweight operational compatibility.

The cheapest provider is not the best partner if they cannot support your next stage of growth.

4. Risk & Contract Structure: What Happens When Things Go Wrong?

Every 3PL proposal should be evaluated for risk allocation.

Review:

• Liability limits
• Insurance requirements
• Inventory shrinkage thresholds
• Term length and termination rights
• Rate escalation language
• Volume minimum commitments
• Exit and transition terms

Cost matters.
But long-term flexibility and risk clarity matter more.

A slightly higher CPO may be worth it if the contract structure reduces downside risk.

5. Long-Term Fit: Will This Work in 3 Years?

The most overlooked dimension in 3PL comparisons is durability.

Ask:

• Does this 3PL typically support brands at our scale?
• Are they optimized for margin or volume?
• Will we be a priority account?
• Do they have the infrastructure to support expansion (new channels, new regions)?

Switching fulfillment providers is disruptive and expensive.

The goal is not to “win” the RFP.
The goal is to build a partnership that lasts.

A Structured Comparison Template (What to Build Internally)

Your internal comparison model should include:

1. Standardized assumptions tab
2. Normalized cost model (monthly + CPO)
3. Capability scorecard
4. Risk and contract summary grid
5. Executive summary view

When proposals are structured consistently, decisions become calmer and clearer.

When they are not, internal debates replace objective analysis.

Common Mistakes Brands Make When Comparing 3PLs

• Comparing rate cards without standardizing assumptions
• Optimizing for lowest pick fee
• Ignoring returns cost impact
• Underestimating onboarding complexity
• Failing to model 12–24 month growth

Structure removes noise.

The Real Advantage: Removing RFP Drudgery

For many brands, the hardest part of comparing 3PL proposals is not analysis—it is normalization.

Manually aligning assumptions, reformatting rate sheets, and chasing clarifications consumes weeks of internal labor.

This is exactly why structured RFP infrastructure matters.

Instead of debating mismatched spreadsheets, brands can evaluate:

• Comparable cost models
• Transparent assumptions
• Capability alignment
• Long-term fit

Calm decisions require structured inputs.

Final Takeaway: Structure Creates Confidence

Comparing 3PL proposals should not feel like guesswork.

When you evaluate:

1. Scope alignment
2. Total cost per order
3. Operational capability
4. Risk structure
5. Long-term fit

—you move from rate comparison to partnership selection.

And that is the real objective.

If your team is currently evaluating fulfillment partners and struggling with inconsistent proposals, the issue is rarely intelligence.

It is structure.

Fulfillment decisions are complex.
They do not need to be chaotic.
