Fulfillment centers are under continuous pressure to do more with less. As e-commerce order volumes grow and client expectations for real-time inventory visibility rise, warehouse operators are managing an expanding administrative workload alongside the physical demands of picking, packing, and shipping. In 2026, virtual assistants are filling a growing share of that back-office capacity.
The Operational Scale of Warehousing in the U.S.
The Warehousing Education and Research Council (WERC) reports that warehousing and distribution is among the fastest-growing segments of the logistics sector, with fulfillment center capacity additions accelerating to meet e-commerce demand. The Bureau of Labor Statistics places warehousing and storage sector employment above 1.9 million workers, and CBRE's industrial real estate research has tracked record-level warehouse construction and leasing activity through the mid-2020s.
That growth creates administrative scale. A 100,000-square-foot fulfillment center managing 20 or more e-commerce client accounts must coordinate inbound purchase orders, maintain accurate inventory records across hundreds of SKUs per client, produce daily or weekly reporting on inventory levels and order fill rates, and reconcile billing against complex multi-tier rate cards. These tasks, handled by operations coordinators or account managers, represent a significant fixed cost that scales with client count rather than order volume.
Where Fulfillment VAs Add Value
Inventory Discrepancy Coordination
Cycle count discrepancies, receiving errors, and damaged goods reports generate administrative follow-up that operations staff must complete without interrupting floor operations. VAs receive discrepancy reports from warehouse management system (WMS) alerts, coordinate with receiving and inventory control teams to gather documentation, prepare discrepancy reports for client review, and track resolution status. WERC benchmarking data notes that inventory accuracy rates and shrink performance are among the top KPIs evaluated by fulfillment clients in annual reviews.
Inbound Purchase Order Management
Client purchase orders arriving from vendors require advance shipment notice (ASN) receipt, appointment scheduling with inbound carriers, and update logging in the WMS. VAs manage this inbound coordination workflow, reducing the time operations supervisors spend on administrative PO management versus directing floor labor.
Client Reporting
E-commerce fulfillment clients expect visibility into inventory on hand, open orders, shipments by carrier, return receipts, and billing by billing period. VAs compile this data from WMS exports or client portals, format it to account-specific templates, and distribute reports on schedule. For fulfillment operators running 15–30 client accounts, weekly reporting can represent 20 or more hours of coordination time—time that is well-suited to a dedicated VA.
Billing and Invoice Administration
Fulfillment billing typically combines storage fees (charged by pallet position or bin slot), handling fees (per inbound and outbound unit), and accessorial charges for value-added services. Reconciling these charges against WMS activity records, preparing client invoices, and following up on past-due balances is procedural but exacting work. VAs trained on fulfillment billing models reduce invoice error rates and accelerate collections.
WMS Familiarity Is a Key Hiring Criterion
Fulfillment VAs need working knowledge of WMS platforms commonly used in the sector: ShipBob, 3PL Central (now Extensiv), Fishbowl, or Manhattan Associates WMS. Agencies that screen for WMS experience and logistics administrative workflows provide immediately productive candidates with minimal onboarding ramp.
Cost Impact at Mid-Size Operators
The Bureau of Labor Statistics places logistics coordinators at median annual wages above $47,000, with benefits adding 20–30% to total employment cost. For fulfillment operators running thin margins on transactional e-commerce accounts, the cost differential between a qualified VA and a domestic coordinator hire directly affects profitability per client.
For warehouse and fulfillment center operators looking to scale client account management without proportional back-office growth, Stealth Agents provides virtual assistants with WMS experience and fulfillment administration skills.
