Your FedEx Rate Sheet Is Not Where Your FedEx Costs Are Decided.

FedEx prices your volume across separately named products and separately named charges. The rules for those charges sit in the FedEx Service Guide, which your pricing agreement incorporates by reference, with the agreement controlling if the two conflict.

ShipSigma models your own FedEx invoice and shipment data against live market data and puts a dollar figure on what your volume should cost. You see the number before you negotiate anything.

See your savings. No obligation, no carrier disruption.

If ShipSigma identifies savings and you engage, the fee structure is performance-based: ShipSigma is paid from savings delivered, not from a flat retainer.

FedEx Names These Structures Separately. Your Invoice Adds Them Together.

Most of the structures below are published by FedEx and priced on their own terms, independent of the base rates in your pricing agreement. FedEx Ground Economy is the exception.

Commercial and residential delivery run as two named products, FedEx Ground and FedEx Home Delivery. Those two set their own length threshold for an unauthorized package while sharing the general weight ceiling (FedEx Service Guide, 2026).
FedEx Ground Economy, formerly SmartPost, is a contractual service with no published rate table. It carries a lower weight and size ceiling than Ground and Home Delivery, and signature proof of delivery is not available on it at all (fedex.com, FedEx Ground Economy).
The demand surcharge FedEx applies to the Residential Delivery Charge applies only to shippers moving more than 20,000 residential and Ground Economy packages combined in a calculation week, and only above a floor set at 105% of a fixed June 2026 baseline. Above that threshold, it is recalculated every week and applied two weeks after the week it measures. A contracted discount or cap on the Residential Delivery Charge does not apply to it (fedex.com, Demand Surcharges, September 2026).
One charge name, Demand Surcharge, covers both U.S. domestic and U.S. international shipments, and FedEx sets demand surcharges for each market. The name on the invoice does not tell you which set of rules produced the amount.
Hundredweight is not a separate charge in FedEx's structure. Multiweight is a shipment-level rating method with its own published rate tables, triggered at 100 pounds total weight (200 pounds for Express Saver). Ground Multiweight is contract-only (FedEx Service Guide, 2026).
FedEx Freight became an independent public company on June 1, 2026, trading on the New York Stock Exchange as FDXF. Volume heavy enough to leave parcel now moves to a separate company, under a separate agreement.

An invoice tells you what FedEx billed. It does not tell you which of these structures set the amount, or what the amount should have been.

FedEx Can Re-Rate a Shipment With No Deadline. Your Side Runs on a Clock.

FedEx reserves the right to audit shipments to verify service selection, weight and dimensions, and to adjust the charges at any time. Where shipment information is missing or entered incorrectly, FedEx bills on its own estimate of the number of packages transported and either the standard dimensional factor at the time of billing or a default weight-per-package estimate set at FedEx's sole discretion (FedEx Service Guide, 2026).

A request to adjust an overcharge runs the other direction. It has to reach FedEx inside 180 days of the invoice date (or ship date if prepaid by cash, check, money order, or credit card) on a U.S. shipment, and inside 60 days on an international one, through the channels FedEx names. Claims of unauthorized account use run on a separate 30-day window.

FedEx also ties that obligation to your own account standing. An account that is, or has been, more than 60 days past due sits outside FedEx's obligation to refund an overcharge.

Cost work runs on the same invoice data those windows govern. That is where an analysis starts, rather than with a rate sheet.

Half a Million a Year. Almost 28% With the Same Carrier.

Half a million in annual savings, from under four hours of client time.

It took less than 4 hours of my time for my company to see half a million in annual savings. No headaches, no feet-dragging negotiations, no confusing documents. It was so easy.

Todd M., Vice President, Food Manufacturer and Distributor

Almost 28% in annual shipping savings, with the same carrier.

The cost modeling and rate simulation let us know the exact savings we would see, down to the last cent. After running our historical data, ShipSigma was able to find us almost 28% in annual shipping savings with our same carrier.

FedEx Publishes What It Charges. It Does Not Publish What You Should Pay.

Most of the structures above are published. FedEx Ground Economy is the exception: it has no published rate table at all. What no carrier publishes is what a shipper at your volume and shipping profile should be paying, which is why that number cannot be read off a rate sheet or a surcharge table.

ShipSigma rebuilds your shipping profile from your own shipment and invoice data and models it against live market data. The output is a dollar figure for what your FedEx volume should cost, and ShipSigma's savings guarantee is quantified from your own analysis.

Nothing about how you ship changes. No carrier change, no service-level change, and ShipSigma does not contact FedEx.

How the Analysis Works

Step 1

You share your FedEx invoice data, exported from your carrier portal.

Step 2

ShipSigma rebuilds your shipping profile at the line-item level and models it against live market data.

Step 3

You get a dollar figure for what your FedEx volume should cost, before any agreement or commitment.

Who This Is For

ShipSigma works with shippers spending $1.5M to $200M a year on parcel. That is the range where the savings a cost analysis identifies are worth the work of finding them.

On the FedEx side, exposure concentrates in a few places. Residential volume that crosses 20,000 residential and Ground Economy packages combined in a week carries the demand surcharge on residential delivery. Oversized and long product meets the Oversize and unauthorized-package thresholds. Volume sitting in Ground Economy has no published rate table to price against.

Small parcel is the core of the work, and freight is covered as well, which matters more now that FedEx's LTL business is a separate company.

Questions Buyers Ask

Do I have to leave FedEx or change service levels?

No. The work is built around no operational change, without changing carriers or service levels. Your FedEx account and your service selections stay as they are.

How is this different from the pricing my FedEx rep already gives me?

ShipSigma prices from your own data: your shipment and invoice data, rebuilt at the line-item level and modeled against live market data. That produces a figure you can hold against what you are quoted.

We ship FedEx Ground Economy. Can you price volume that has no published rate?

Yes. FedEx Ground Economy is a contractual service with no published rate table, so the only way to price it is from your own invoice data. That is what the analysis runs on.

What happens to our FedEx LTL freight?

FedEx Freight became an independent public company on June 1, 2026, so LTL now sits with a separate company under a separate agreement. ShipSigma covers freight as well as small parcel.

Does this include auditing our FedEx invoices?

The analysis is built by rebuilding your invoices at the line-item level, so billing errors and misapplied charges surface as part of it. An ongoing parcel invoice audit is a separate ShipSigma service. Separately, FedEx's own adjustment windows bound how far back a correction can reach.

What does it cost, and how much of my time does it take?

The analysis is no-cost and no-obligation, and ShipSigma is paid from savings delivered rather than a flat retainer. Client time is measured in hours.
