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, geographies, fulfillment locations, and time requirements, the harder it is for you to create consistent processes and policies around static pricing. Carriers know this, which is why they charge a premium to eliminate complexity. Here are common negotiation tactics you may hear from a carrier rep: - “We will give you this special price if you go with this single shipping method.” - “Use us for all your shipping, and we will give you a discount once you hit a high volume.” - “Sign this two-year contract to lock in a price so you know it won’t change on you.” - “Use this discounted rate for this type of parcel profile, and you’ll save more compared to any other option.” But all carrier rep tactics are designed to lock you into their ecosystem at a price higher than you realize. The result? Higher shipping prices. #### Inconsistent carrier contract terms If you accept that shopping carrier rates is smart, the next challenge is found in the inconsistencies between contract structures. Here are four properties found in every contract across any carrier: - **Base shipping rates**: The per-package rate across zones and dim weights. The heavier, faster, and farther the shipments, the more it costs. - **Minimum charges**: All carriers set a floor of how much they will charge. You pay the higher value between this minimum charge or the computed charge. - **Dimensional weight (dim weight) divisor**: Dim weight is how carriers standardize across size and weight for easy computations. Multiply the length, width, and height, then divide by the dimensional divisor. - **Surcharges / Accessorials**: Charges that have been added over time to increase margins. #### Asymmetric data for negotiation Carrier sales reps often have some incentive around increasing margins per contract, giving them access to more data about your business than you have. For example, you might be offered an enticing flat fee for US-wide shipping that may not be in your best interests depending on your shipping profile. ### Contract ownership The last problem is understanding who owns the contract. Here are some options: - Create an account directly with a carrier. - Use a 3PL who has a contract with a carrier and resells those rates. - Work with your ecommerce store platform that has a contract with carriers. #### Importance of benchmarking data You lose the negotiation if you lose the asymmetric data game. Carriers will know averages for a company your size, but you have to benchmark comparables to know what to ask for. ### Create a shipping matrix Build a matrix by charting zones and typical package weights, and overlay historical shipping data and costs to find patterns. ### Apply carrier contract optimization across multiple shipping profiles Negotiate different rates with different carriers based on your shipment's size and weight profile to minimize costs. ### Engage with multiple carrier contracts Working with multiple carriers gives you leverage during negotiations. ### The ideal standard for ecommerce 1. Collect as much data about your shipping as possible. 2. Create a shipping matrix. 3. Isolate specific areas to negotiate. 4. Manage multiple carrier contracts. 5. Ensure at least one fast and one free shipping option for customers. 6. Regularly renegotiate and leverage competition between carriers. ### Gotchas - Understand contract durations and minimum spend requirements that can affect perceived discounts. - Avoid rebates in favor of upfront discounts.
