The signal
Total business inventories rose 0.8 percent in July 2026 to $2,764.7 billion, the largest one month build since March, according to the Census Bureau's Manufacturing and Trade Inventories and Sales report released September 16. Sales rose 0.3 percent for the month, so inventories outgrew sales in July. The inventories to sales ratio ticked up to 1.30 from 1.28 in May, still below last July's 1.37. The build is not even across segments. Merchant wholesalers' ratio moved from 1.15 in May to 1.20 in July, the sharpest segment move in the data. Manufacturers have held flat at 1.47 for three straight months, and retailers have barely moved, holding between 1.25 and 1.27 since February. Meanwhile warehouse and storage payrolls peaked in June at 1,845,800 jobs and have fallen for two straight months, landing at 1,837,400 in August, back to the April level.
Why it matters to shippers
More inventory sitting against flat to declining warehouse headcount is a receiving capacity story, not just a balance sheet one. Wholesalers are the segment absorbing the build, their inventory to sales ratio has risen more than the other two tracked segments since May, and the same warehouses handling that inbound volume have two fewer months of staff than they had in June. When receiving gets busier with fewer hands, the step most likely to get compressed is the one that decides whether a shortage is recoverable: comparing what a purchase order ordered, what the bill of lading says was tendered, and what was actually counted on the dock. Skip that comparison under time pressure and an inbound shortage does not just sit unresolved, it becomes permanent inventory variance, because the units are absent from stock while the paperwork still says they arrived.
The playbook
Shipping: with wholesaler inventories having built more than the other two tracked segments since May, expect inbound volume to hold or grow into the next reporting cycle. Confirm that whoever receives freight is still logging a classification on every shortage, not just a generic short note, because that classification is the record any later recovery depends on.
Warehouse: two straight months of headcount decline running into rising inbound volume is a setup for skipped steps. Build the three way comparison, purchase order against bill of lading against actual count, into the receiving screen itself rather than a later audit, since spare staff to run one may not exist.
Finance and procurement: a rising inventory to sales ratio means more capital is sitting in inventory. Some of that balance may include shortage variance that was never billed back to anyone. Ask whether unclassified shortages are being absorbed silently into inventory counts rather than tracked as a recoverable loss.
One question answered
What does classifying an inbound shortage actually decide? It decides whether the missing units are recoverable, and from whom. A carrier shortage means the purchase order and the bill of lading agree on the piece count, but fewer pieces arrived than the bill of lading lists, so the carrier received those pieces and did not deliver them. A supplier short-ship means the bill of lading itself already shows fewer pieces than the purchase order called for, meaning the vendor never tendered them and the carrier delivered exactly what it was given. Both can occur on one shipment. One caveat matters here: most inbound freight is vendor routed, so the vendor, not the receiver, typically holds the contract of carriage and is the practical party to pursue, even when the evidence points to a carrier shortage. Who may pursue a carrier directly depends on the freight terms and varies by shipment.

LanePilot field note: fuel surcharge movement
On highway diesel averaged $6.285 a gallon for the week ending September 14, 2026, up 31.8 cents from the prior week and up $2.546 from a year earlier, according to the Energy Information Administration's weekly Gasoline and Diesel Fuel Update. Diesel has climbed 68.6 cents in the two weeks since August 31, when it stood at $5.599. A move that size flows straight into whatever fuel surcharge table a shipper is billed against, but not every invoice draws from the table the contract actually names. Carriers publish more than one fuel surcharge schedule, and rate agreements typically specify which schedule applies by name and by the base price that triggers each step. When diesel moves this fast, it is worth pulling the current invoice's surcharge percentage and checking it against the exact schedule named in the contract or rate confirmation, not against whatever table happens to look current online.
