How UPS & FedEx Contracts Work
Shipping contracts with UPS and FedEx govern every aspect of your pricing relationship with those carriers — base rates, discounts, surcharge treatment, minimum commitments, and contract duration. Unlike published tariff rates (which are list prices with no customization), negotiated contracts apply agreed-upon discount structures to your account, reflecting your volume, package profile, and competitive situation.
Most shippers significantly underestimate the complexity of their carrier contracts. A standard UPS or FedEx agreement contains 250+ individually negotiable line items, including service-level discounts, minimum charges, surcharge caps, incentive tiers, and early termination provisions. Understanding the terminology in these agreements is the prerequisite to negotiating them effectively.
Earned Discounts
An earned discount is a percentage reduction off the carrier’s published tariff rate that a shipper earns based on their weekly shipping revenue. Earned discounts are tiered — as your weekly revenue with the carrier increases, you move into higher discount bands and receive greater percentage reductions.
The earned discount structure is one of the most impactful components of a carrier contract. It is often the single largest source of savings relative to list rates. However, earned discount structures are often set based on volume at the time of negotiation — if your volume grows, you may have outgrown your discount tier without realizing it.
Portfolio Tier Incentive (PTI)
The Portfolio Tier Incentive (PTI) is a UPS-specific contract feature that rewards shippers for using multiple UPS service lines — ground, air, international — rather than concentrating volume in a single service. PTI discounts are layered on top of base earned discounts and apply across the portfolio of services.
Shippers sometimes inadvertently fall out of their PTI tier by shifting volume to a competitor for a specific service, triggering retroactive discount reductions across all services. Understanding your PTI thresholds before making service changes is critical.
Flat Rate Pricing
Flat rate pricing sets a fixed price for specific shipments regardless of actual weight or distance, up to defined limits. Both UPS and FedEx offer flat rate products (UPS Simple Rate, FedEx One Rate) for smaller parcels using standardized packaging and a single price per package for any qualifying destination within the continental United States.
Flat rate pricing can offer significant savings for shippers with high-zone or heavyweight packages. However, flat rate products have package size and weight limits, and they typically do not allow contract discounts to be applied on top.
Minimum Charge
The minimum charge (also called the minimum billable weight or floor charge) is the lowest amount a carrier will bill for any single shipment, regardless of the calculated rate. If a shipment’s calculated transportation charge falls below the minimum charge, the carrier bills the minimum instead.
For lightweight, short-zone shipments, minimum charges can represent significant overcharges relative to the actual rate calculation. Shippers with a large proportion of very light packages should audit their invoices for minimum charge exposure and negotiate minimum charge thresholds in their contracts.
Minimum Commitment
A minimum commitment (or minimum revenue commitment) is a contractual obligation to ship at least a specified revenue amount per week with the carrier. If your actual weekly revenue falls below the committed minimum, the carrier may reduce your discounts, charge back incentive payments, or reclassify your account.
Shippers should negotiate minimum commitments that are realistic and achievable, with appropriate relief provisions for business disruptions, seasonal volume swings, or carrier service failures.
Contract Term and Duration
The term of a carrier contract is the period during which its pricing and conditions are in effect — typically 12 months, though longer terms (2 to 3 years) are sometimes offered in exchange for guaranteed volume commitments or more favorable rate structures.
Longer terms provide pricing stability but reduce flexibility to renegotiate as your business grows or as competitive alternatives emerge. In a rising rate environment, locking in rates for multiple years can provide meaningful protection against annual General Rate Increases (GRIs).
Grace Period
A grace period in a carrier contract is a defined window (typically 30 to 90 days) at the start or end of the contract during which reduced performance against minimums does not trigger penalties or discount reductions. Grace periods provide time for volume ramp-up at the start of a new agreement, or wind-down buffer when transitioning carriers.
Grace periods are frequently negotiable and worth including in any contract with minimum commitments — they protect against penalties during legitimate business disruptions.
Early Termination Clauses
An early termination clause defines the consequences if either party ends the contract before its agreed expiration date. For shippers, early termination typically involves repaying some or all incentive payments or discounts received during the contract period — a significant financial exposure that can reach hundreds of thousands of dollars for large-volume shippers.
Key questions to ask: What triggers early termination? How are repayment amounts calculated? Are there carve-outs for carrier service failures? What notice period is required? Early termination language should always be reviewed by an expert before signing.
Tariff Rates
A tariff in domestic shipping refers to the carrier’s published base rate structure — the list prices from which discounts are calculated. UPS and FedEx publish their tariffs annually (effective January 1), incorporating their annual General Rate Increases. Contract discounts are applied to tariff rates, not to the final invoiced amount. If carriers raise tariff rates by 5% in a GRI while your discount structure stays fixed, your net cost increases proportionally.
Money-Back Guarantee / Guaranteed Service Refund (GSR)
Both UPS and FedEx offer a Guaranteed Service Refund (GSR) — also called the money-back guarantee — for late deliveries on eligible express and time-definite services. If a qualifying shipment is not delivered on time, the shipper is entitled to a full refund of transportation charges.
Filing for GSR refunds requires identifying late shipments and submitting claims within the carrier’s deadline (typically 15 days of invoice). Many shippers leave substantial GSR refunds unclaimed due to the manual effort required. Shipware’s invoice audit service identifies and claims GSR refunds systematically as part of ongoing parcel audit operations.
Service Guide
The service guide is the comprehensive reference document published annually by each carrier that describes available services, rate structures, surcharge schedules, terms and conditions, and packaging requirements. When negotiating contracts, shippers should always compare their contracted rates against the current year’s service guide to verify that discount calculations are applied correctly.
How Shipware Renegotiates Carrier Contracts
Carrier contracts are renegotiated every 1 to 3 years, but most shippers negotiate without market intelligence, benchmarking data, or knowledge of what is actually achievable for their account profile. Shipware brings former UPS and FedEx pricing executives to every negotiation, with access to benchmarking data from hundreds of similar accounts and direct knowledge of where carrier flexibility exists.
