Two cost pressures are hitting 3PL operations at the same time, and they're pushing in opposite directions.
Tariff-driven inventory volatility is driving volume up. Abandoning just-in-time (JIT) strategies, at least for now, brands are buffering 60 to 90 days of inventory to combat uncertainty. They're shifting sourcing and sending bigger inbound shipments to warehouses that weren't designed for that complexity. More products. More SKU variations. More pressure on receiving.
At the same time, rising labor costs mean every hour of operational friction is more expensive than it was last year. Warehouse wages have climbed steadily nationwide. An inefficient shift eats into margins faster than ever.
When they happen together, these problems compound. There's more inventory to move, with more expensive labor moving it, through systems and processes that simply don't have the supply chain visibility to keep up.
Faced with these challenges, it's easy to jump into problem-solving mode. But first, ask yourself and your team these questions: What does your on-hand inventory look like for your top three clients? How much was billed last week to each client? And if a client added 50 new SKUs tomorrow, how long would it take to get them set up?
If you consulted a spreadsheet or a supervisor, or had to dig through more than one system to find the answer, read on.
When price-and-volume stress hits, receiving slows down. ASN volumes increase. Inbound shipments arrive with new SKU configurations because brands have changed suppliers.
It's an expensive delay, because inventory sitting on the dock isn't sellable, can't be billed for storage and simply isn't accounted for in the system until someone works through the backlog.
Slotting plans go stale faster. SKU velocity that made sense in Q1 conflicts with Q3 reality. Routing built for last quarter's pattern means pickers walk further on every order.
And as operations grow more complex, so does the manual coordination required to hold it all together. Every workaround adds time. Every manual handoff adds risk. With labor costs climbing, that friction is no longer just an operational inconvenience. It's a margin problem.
Most traditional warehouse management systems are built for predictable inventory flow. They tend to fail in three critical places when too much changes at once.
Receiving capacity. If the ASN process can't handle bigger inbound volumes or unfamiliar SKUs at scale, the dock becomes a bottleneck. Your team works longer to catch up. Labor costs climb to handle the same volume you've always managed.
Replenishment logic. Static pick assignments fail to adapt when SKUs move differently than expected. Manual workarounds can keep things running, but consume hours that add up shift after shift.
Billing capture. With manual reconciliation of new charges, special handling or modified workflows, charges slip through the cracks. The more your operation changes, the wider the gap gets.
Today's 3PLs need to be adaptable to stay ahead — and that means running systems that absorb variability without forcing teams to compensate or dramatically change their workflows.
Flexible pick assignments. When SKU velocity changes, the system needs to allow replenishment from multiple overflow locations without a manual workaround. If a single SKU now needs to be picked from two zones, modern systems route inventory and pickers accordingly. With labor costs climbing, route efficiency is margin efficiency.
Automated routing rules. In complex warehouse environments, inventory placement can shift from day to day. Advanced warehouse management software automatically adjusts routing, protecting picker productivity even when the underlying operation is in flux.
Granular billing capture. Manual billing catch-up is always a losing race. Your WMS should capture billable work at the moment it happens, rather than relying on end-of-month reconciliation.
Carrier rate-shopping built into the workflow. Carrier rate increases hit your margin directly when rate-shopping isn't part of the label creation process. All major carriers are raising rates in 2026, and selecting the right one for each shipment can make a measurable impact on your bottom line.
Lot-level traceability. Just-in-case inventory strategies mean older stock can sit alongside newer arrivals. For food, beverage, pharma and any highly regulated category, FIFO and FEFO compliance becomes harder to track by hand. The system should enforce it at the pick, every time.
When inventory volume jumps, a new SKU profile shows up or a carrier raises rates mid-quarter, the operations that absorb the change fastest are the ones whose systems handle the variation automatically. The ones that don't add headcount, workarounds and manual coordination every time something shifts. That's the difference between a system that scales with your business and one that becomes the bottleneck.
InfoPlus was built for exactly this kind of complexity: variable inventory, billing accuracy at scale and the kind of operational flexibility that growing 3PLs actually need.
