Summary

Two years is a long time in parcel. The agreement that fit your business two years ago can cost you real money once peak arrives, when higher volumes magnify every mismatch between your contract and how you ship. Here is where those gaps hide, and how to close them before November.

Key Takeaways

• If your volume commitments were built around your business two or more years ago, you can either fall below your discount thresholds or send the carrier more volume than your current rates reflect.
• Carrier discounts focus on specific weight breaks, zones, and service levels that may no longer match how you ship.
• Peak surcharges scale with volume, so any misalignment in your base rates costs the most in the fourth quarter.
• A package-level review of your trailing 12 months, done before peak, still leaves time to reset minimums and rebalance tiers.

If you signed a parcel agreement two or more years ago, it reflects the business you were running then. Your volumes, packaging, and network probably look a lot different now. You almost certainly run a different operation, and in ways nobody could have predicted then.

Your contract, meanwhile, has not changed at all, except that your rates have climbed with the annual General Rate Increases (GRIs) and other carrier rate changes since. Why does that matter right now? Peak season is when higher costs and higher volumes make every extra shipment especially expensive. And the pain comes from a mix of factors that reach well beyond rates. Here are the ways the details inside your agreement can compound the problem.

How do volume commitments create peak-season risk?

Most carrier agreements tie discounts to minimum volume or revenue commitments. If your volumes have declined during the past two years, you may be at risk of falling below those thresholds, which can mean losing discount tiers or triggering repricing provisions, often at the worst possible moment. If your volumes have grown, the problem cuts the other way. You may be delivering more revenue to the carrier than you committed to, without any corresponding improvement in your rates. Either way, the commitment was calibrated to a business that no longer exists.

Earned discounts work on a sliding scale: the more revenue you run through a carrier, the deeper your discount, with each step tied to a defined volume band. In an aging carrier agreement, those bands were set against your previous run rate. If shipping has grown, you may be locked a tier or two below the discount your current volume would earn in a fresh negotiation. If you have diversified into regional carriers or consolidators since then, you may be hovering just above a tier boundary, at risk of dropping through it mid-peak, precisely when you are spending the most.

What happens when your package profile changes?

Carrier discounts are not spread evenly. They focus on specific weight breaks, zones, and service levels, and a well-negotiated contract aligned them with where you were at the time. If your average package has gotten lighter, if a new fulfillment location has changed your heaviest zones, or if your service mix has moved between ground and air, your deepest discounts may now sit in bands you rarely use. This matters most at peak, when the bulk of your volume flows through the bands you use today while your contract is still built around the ones you used just a couple of years ago.

Peak surcharges compound the problem. Demand surcharges layer on top of your base rates during the fourth quarter, and they scale with the same volume that exposes every other misalignment. When your base rates are misaligned, everything layered on top costs more too. A contract that leaks 2 or 3 percent in June leaks much more in November, because peak concentrates a disproportionate share of the year's shipping costs into a handful of weeks.

How does a changing network affect your parcel costs?

Your shipping network can change just as significantly as your volumes and package profile. Origin drives a large share of your parcel costs, so an agreement negotiated around your former network can price today's shipments very differently.

The same is true on the destination side. Customer locations can change as you expand into new markets or pull back from certain regions. The last mile is where much of your delivery cost is applied: McKinsey research puts it at half or more of total parcel delivery cost, and it climbs with distance and delivery density. A growing share of shipments to distant zones, for example, can push more volume into higher-cost bands the original agreement barely addressed. A more regional customer base may leave your best rates concentrated in zones you no longer ship to as often.

If your origin and destination mix has changed, the discounts and incentives that once looked competitive may no longer align with where your shipments are moving.

Why does this review need to happen now?

Analyze your shipping patterns now, and you still have room to act. You have time to reset minimums, rebalance discount tiers, or realign incentives before peak season hits. But doing the analysis well takes more than pulling a report and comparing totals. The most useful review combines detailed shipment data, contract terms, and the technology to model how changes in your business affect your transportation costs.

This is where working with a parcel contract negotiation partner can help. The right partner can use technology to analyze the previous 12 months of shipment data at the package level and identify where your agreement is misaligned with how you ship today.

Most companies are surprised by what they find. Nothing was done wrong when the contract was signed; two years is simply a long time in parcel. You can be sure the carriers continuously re-run this math on their side. Companies that use the right technology and expertise to do the same at least once a year stay better positioned to keep their agreements aligned with current needs.

Before peak 2026 exposes cost differences on every package invoice, it is worth knowing whether your contract still reflects where your business is today.

FAQs

How often should I review my parcel carrier contract?

At least once a year. Carriers continuously re-run the math on their side, and a yearly review keeps your agreement aligned with how you ship today.

What data do I need to evaluate my contract before peak?

The most useful review combines a trailing 12 months of shipment data at the package level, your current contract terms, and technology to model how changes in your business affect your costs.

Is it too late to make changes before peak 2026?

Not if you start now. There is still time to reset minimums, rebalance discount tiers, and realign incentives before peak volume hits.

Why does peak season make contract misalignment worse?

Peak concentrates a large share of the year's shipping costs into a few weeks, and demand surcharges scale with that volume. Any misalignment in your base rates costs the most exactly when you ship the most.
