Introduction

If outbound shipping isn’t the top operational expense for ecommerce businesses, then it’s always second or third. Few areas have more meaningful impact on margin and profitability than reducing outbound shipping. ...

This playbook will walk ecommerce operators through the best practices for negotiating carrier rates to reduce overall spending.

Who is this playbook for?

Read this if you are in charge of establishing contracts with shipping carriers and want to know how to negotiate shipping rates to secure the cheapest per-parcel pricing possible.

The challenge of carrier rate negotiation

Many difficulties exist when it comes to carrier rate negotiation. Almost all problems can be summarized by (a) purposeful complexity, and (b) asymmetric data giving carriers an advantage over you. We’ll break down the problems in more detail below.

Overly complex contracts

Negotiating carrier rates is confusing — at least it appears that way. The reason is complexity. The more variance with package dimensions or weights, package types, ...

Inconsistent carrier contract terms

If you accept that shopping carrier rates is smart, the next challenge is found in the inconsistencies between contract structures. ...

Asymmetric data for negotiation

Carrier sales reps often have some incentive around increasing margins generated per contract. ...

Contract ownership

The last problem is the confusing landscape of who owns the contract. ...

What matters to ecommerce?

With the common problems laid out, the final point to highlight centers around the unique business models of ecommerce. ...

The Plays

As we build out the best collection of plays for negotiating carrier rates, let’s discuss how a typical contract works.

Every package you ship has the following properties:

Weight and dimensional size, or dim-weight when calculated.
Fulfillment center address that you are shipping from, which defines the Zones.
Customer destination address, which exists in a Zone relative to the FC chosen.
Speed requirements, such as “promised to customer in 3 days.”

Importance of benchmarking data

You lose the negotiation if you lose the asymmetric data game. ...

Create a shipping matrix

Build a multi-dimensional matrix by creating separate tables and overlaying the data. ...

Apply carrier contract optimization across multiple shipping profiles

Taking our matrix above, another strategy is optimizing certain profiles for certain contracts.

Engage with multiple carrier contracts

Working with multiple carriers gives you leverage in a few key areas. ...

Skip the RFP

The typical way to open a contract negotiation is to send an RFP to a carrier. ...

Position a change in the company as a reason to negotiate

Ultimately, what matters to carriers is volume because they have poor margins and only make meaningful profits at scale. ...

The ideal standard for ecommerce

Make sure you have as much data about yourself as the carrier as on you
Make a shipping matrix along with multiple shipping profiles based on that data
Isolate specific areas across shipping profiles that will have the biggest impact on operating cost or performance, and seek out the best carrier method for that profile
Lean into the complexity of securing and managing multiple carrier contracts
Optimize across carriers for at least one fast option for customers, and one free option for customers
Readily renegotiate and play carriers off each other

Gotchas

Understand contract durations

There is a balance between the value of short-term and long-term contracts. ...

Watch for minimum spend misalignment

You may be enticed by a 50% discount on a certain profile, but if the average rate for that Zone/Dim-weight profile is $10 ...

Avoid any and all rebates

If you have to choose, don’t do rebates, do discounts. ...

Protect your rights

Carriers will want you to waive many rights. ...

Metrics

Cost-per-package: Track this, and add as much granularity for pivot possibilities as possible (rate per zone, etc.).
Cost-per-pound: Same thing, but measure per pound.
Cost-per-dim-weight: Same, but per dim-weight.
SLA performance of carriers: Track how often carriers don’t deliver at the times they say they will ...
Zone distribution: Breakdown of package volumes, costs, performance, etc by zone.
