U.S. business backlogs are rising again, creating a familiar challenge for supply chain and distribution leaders: how do you increase warehouse capacity when demand increases without committing to permanent labor that may not be needed six months from now?
New economic data released in October 2026 shows that order backlogs across the U.S. services sector have climbed to their highest level since July 2022.
For warehouse and distribution center operators, that matters.
A growing backlog is not simply an economic indicator. Eventually, more business activity translates into more freight arriving at docks, more inventory moving through facilities, more orders requiring fulfillment, and greater pressure on the people responsible for keeping product moving.
The question becomes:
If 20% more work arrived at your distribution center next week, where would the additional capacity come from?
For many operations, the answer cannot simply be “hire more people.”
Why Are Supply Chain Backlogs Rising in 2026?
According to Reuters, U.S. services-sector order backlogs increased in September 2026 to their highest level since July 2022.
At the same time, businesses are contending with higher input costs, fuel expenses, supply constraints and ongoing global supply chain disruption.
The pressure is appearing across logistics as well.
Reuters reported separately on October 6 that global supply chain disruption and resilient freight demand are increasing demand for higher-value logistics services, including warehousing.
Together, those trends point toward an important operational reality:
Companies may need more supply chain capacity at precisely the time they are under greater pressure to control costs.
That creates a difficult balancing act for distribution center operators.
Adding too little labor can create service failures and bottlenecks.
Adding too much permanent labor can leave the operation carrying unnecessary fixed costs if volumes change.
The answer is not necessarily more headcount.
The answer may be more flexible capacity.
What Happens When Higher Volume Reaches the Warehouse?
Freight does not stop creating cost or operational pressure once it reaches the distribution center.
A facility must still have enough capacity to:
-
Unload inbound trailers
-
Receive product
-
Move inventory out of staging areas
-
Complete put-away
-
Replenish pick locations
-
Select orders
-
Prepare outbound shipments
-
Load trailers
-
Maintain required service levels
When one part of that process begins falling behind, the impact can spread rapidly through the building.
An unloading delay can create dock congestion.
Dock congestion can slow receiving.
Receiving delays can prevent inventory from becoming available for picking.
Picking delays can affect outbound orders.
And suddenly, a facility that technically has enough physical space and inventory does not have enough operational capacity.
That distinction is increasingly important.
Inventory Availability Is Not the Same as Operational Capacity
Supply chain planning often focuses heavily on whether a company can obtain inventory and move it through transportation networks.
But having product available does not automatically mean a distribution center can process it efficiently.
Operational capacity depends on several interconnected resources:
Labor capacity. Are enough productive associates available when the work arrives?
Leadership capacity. Is there sufficient frontline supervision to manage additional people and volume?
Dock capacity. Can inbound freight be processed quickly enough to prevent congestion?
Throughput capacity. Can receiving, replenishment, picking and shipping keep pace with one another?
Management capacity. Does the existing leadership team have the bandwidth to solve labor issues while also running the broader operation?
A constraint in any one of these areas can become the bottleneck for the entire facility.
Why Permanent Hiring May Not Be the Best Response to a Backlog
When volume rises, the instinctive response is often to increase hiring.
Sometimes that is appropriate.
But permanent hiring carries risk when the duration and magnitude of increased demand remain uncertain.
A company may face:
-
Recruiting costs
-
Training expenses
-
Additional supervision requirements
-
Higher benefits costs
-
Overtime during the ramp-up period
-
Turnover before new employees become fully productive
-
Excess labor expense if volume later declines
There is also a timing problem.
Traditional hiring may take weeks or months.
The freight may already be arriving.
For operations experiencing temporary surges, unpredictable inbound volume, labor shortages or sudden increases in demand, a more flexible labor model can provide additional capacity without permanently increasing the organization’s internal headcount.
How Can Distribution Centers Add Warehouse Capacity Without Adding Permanent Headcount?
Distribution centers can increase capacity by outsourcing specific warehouse functions to a managed labor provider or, where broader support is needed, engaging a third-party logistics provider to assume greater operational responsibility.
The right model depends on where the constraint exists.
1. Outsource High-Labor Warehouse Functions
A facility does not necessarily need to outsource its entire operation.
Many companies begin with specific labor-intensive functions such as:
-
Receiving support
-
Put-away
-
Replenishment
-
Loading
-
Cross-docking
-
Returns processing
This allows internal leadership to maintain control of the broader operation while transferring responsibility for a defined function to an outside partner.
2. Increase Capacity Through Managed Warehouse Labor
Managed warehouse labor differs from traditional temporary staffing.
Rather than simply providing workers, a managed labor model can include recruiting, training, frontline supervision, productivity management and accountability for designated warehouse functions.
That distinction becomes particularly important during periods of higher volume.
Adding ten temporary workers still requires someone inside the customer’s organization to supervise those ten workers.
Managed labor adds both workforce capacity and operational management capacity.
3. Use Contingency Labor for Sudden Volume Surges
Some warehouse challenges cannot be predicted months in advance.
Facilities may experience:
-
Unexpected inbound surges
-
Labor shortages
-
Severe weather disruptions
-
Facility start-ups
-
Seasonal peaks
-
Second- or third-shift coverage needs
-
Operational recovery situations
Rapid-deployment contingency labor can help operations respond without permanently expanding the workforce.
The objective is straightforward:
Match labor capacity to the work that actually needs to be completed.
4. Consider Full 3PL Warehouse Management When the Constraint Is Broader Than Labor
Sometimes the underlying problem is not simply workforce availability.
An operation may also be struggling with:
-
Productivity
-
Turnover
-
Frontline leadership
-
KPI management
-
Workflow execution
-
Safety performance
-
Process consistency
-
Management bandwidth
In those situations, adding additional associates may treat the symptom without solving the broader operational challenge.
Full 3PL warehouse management transfers greater responsibility for day-to-day warehouse execution to an experienced operating partner.
That can include labor, leadership, unloading, receiving, inventory movement, order fulfillment, shipping, safety, performance management and continuous improvement.
The company gains capacity without having to internally build every layer of infrastructure required to support that growth.
How Do You Know If Your Warehouse Is Approaching a Capacity Problem?
The warning signs often appear before a major service failure occurs.
Distribution center leaders should pay attention when they begin seeing:
-
Increasing overtime
-
Trailers waiting longer to be unloaded
-
Growing inbound staging areas
-
Receiving falling behind
-
Product waiting for put-away
-
Rising labor turnover
-
Missed productivity targets
-
Supervisors spending most of their time covering labor gaps
-
Increasing dependence on temporary staffing
-
Higher detention exposure
-
Missed outbound cutoffs
-
Customer service issues caused by warehouse delays
Individually, each issue may appear manageable.
Together, they may indicate that warehouse capacity is no longer aligned with business demand.
The Question Supply Chain Leaders Should Ask Now
Current economic conditions make forecasting particularly difficult.
Businesses are seeing continued demand while also facing higher operating costs and supply chain disruption.
That makes one question especially important:
How much additional volume could your warehouse absorb today without sacrificing service, increasing overtime or permanently adding headcount?
If the answer is unclear, the operation may have less flexibility than leadership assumes.
Supply chain resilience is not simply the ability to source goods or secure transportation.
It is also the ability to flex the operation inside the four walls when conditions change.
Companies that build variable capacity into their distribution strategy can respond to increased demand without waiting for a traditional hiring cycle—or carrying unnecessary permanent labor when volumes normalize.
Building Flexible Warehouse Capacity With FHI
For more than three decades, FHI has supported distribution and supply chain operations with workforce and warehouse execution solutions designed around the needs of individual facilities.
Depending on the operational challenge, FHI can support companies through:
Unloading services for facilities that need greater consistency and productivity at the inbound dock.
Managed warehouse labor for companies that want an experienced partner to recruit, manage and oversee designated warehouse functions.
FHI NOW contingency labor for operations requiring rapid workforce support during unexpected shortages, surges or operational disruptions.
Full 3PL warehouse management for organizations seeking broader responsibility for warehouse labor, leadership and day-to-day operational execution.
The goal is not simply to put more people in a building.
It is to create enough productive, accountable capacity to keep freight and inventory moving as business conditions change.
Because when supply chain backlogs begin growing, the companies best positioned to respond are not necessarily the ones with the largest workforce.
They are the ones with the greatest ability to flex.
Frequently Asked Questions
How can a warehouse increase capacity without hiring more employees?
A warehouse can increase capacity without adding permanent employees by outsourcing specific functions such as unloading, receiving, put-away, replenishment, picking or loading. Managed warehouse labor and contingency workforce solutions can provide additional labor and supervision while allowing the company to avoid permanently increasing internal headcount.
What is flexible warehouse capacity?
Flexible warehouse capacity is the ability to increase or decrease operational resources as workload changes. It can include scalable labor, managed warehouse services, contingency workforce support, additional shifts and third-party warehouse management.
What is the difference between temporary staffing and managed warehouse labor?
Temporary staffing typically provides individual workers that remain under the customer’s supervision. Managed warehouse labor generally includes workforce recruiting, training, supervision, productivity management and accountability for designated warehouse functions.
When should a company consider outsourcing warehouse labor?
Warehouse labor outsourcing may be worth considering when a facility experiences persistent turnover, overtime, labor shortages, inconsistent productivity, seasonal demand, inbound congestion, difficulty recruiting or sudden increases in workload.
Can outsourced warehouse labor support only part of an operation?
Yes. Companies can outsource individual warehouse functions rather than the entire facility. Common starting points include unloading, receiving, put-away, replenishment, picking, loading, cross-docking and returns.
When should a company consider full 3PL warehouse management?
Full 3PL warehouse management may be appropriate when operational challenges extend beyond labor availability and include leadership bandwidth, productivity, safety, workflow execution, KPI accountability or overall warehouse performance.
How can warehouses prepare for unexpected increases in volume?
Warehouse operators can prepare by identifying their likely capacity constraints, tracking labor productivity and overtime, creating contingency workforce plans, evaluating scalable labor partners and determining which functions could be quickly expanded or outsourced if volumes increase.
