Fulfillment centers operate on thin margins and high volume. The pressure to process orders accurately, invoice clients correctly, and respond to merchant and end-customer inquiries quickly is relentless—particularly during peak shipping seasons when order volume can spike 200–400% above baseline. In 2026, fulfillment centers of all sizes are integrating virtual assistants to manage the administrative layer of their operations, freeing warehouse managers and operations leads to focus on physical throughput and quality control.
The Administrative Burden Behind the Warehouse Floor
Every order processed by a fulfillment center generates administrative activity: order receipt confirmation, client billing entry, shipping confirmation, returns processing documentation, and customer communication management. According to a 2025 report by the Warehousing Education and Research Council (WERC), administrative overhead—including billing, reporting, and client communications—accounts for 15–20% of total operating hours in mid-size fulfillment operations, a proportion that grows during peak periods when exception volume spikes.
What Virtual Assistants Manage in Fulfillment Centers
Order Processing Administration
VAs are handling the administrative tasks surrounding order processing: order import and entry into fulfillment management systems, exception flagging for orders with missing or incorrect data, backorder notification management, and order status update communications to merchants. While the physical picking, packing, and shipping requires warehouse personnel, the administrative coordination surrounding each order is well-suited to remote VA support.
Client Billing
Fulfillment center billing is complex—storage fees, pick-and-pack fees, special handling charges, returns processing fees, and outbound shipping costs must all be tracked by merchant and invoiced accurately. Billing disputes are a leading cause of merchant churn in the fulfillment industry. VAs are managing monthly billing compilation, invoice preparation, fee reconciliation, and payment follow-up. According to the Fulfillment Association, invoice accuracy improvements of 5–10% can reduce client dispute resolution time by 30–40%, directly protecting merchant relationships.
Customer Communications
End-customer inquiries about order status, delivery issues, and returns are routed through merchants but often require fulfillment center coordination to resolve. VAs are managing the merchant-facing communications layer: responding to merchant inquiries about specific orders, coordinating returns authorization processes, communicating carrier exception resolutions, and managing customer refund documentation. This responsiveness improves merchant satisfaction scores and reduces the escalation rate of routine shipping issues.
Operations Coordination
VAs are supporting operations leads with scheduling coordination, vendor communication management, carrier contract administration, and internal reporting compilation. This administrative support layer frees operations managers to spend more time on floor supervision, quality control, and process improvement—the activities that directly drive throughput and accuracy rates.
The Peak Season Capacity Problem
Fulfillment centers face a well-known staffing problem during peak seasons: warehouse headcount can be scaled through temporary workers, but administrative capacity is harder to flex. When order volume triples, billing volume triples, customer inquiry volume triples, and exception handling volume spikes. VAs provide administrative surge capacity that can be scaled with order volume, avoiding the cycle of administrative backlogs that damage merchant relationships during the most commercially critical periods of the year.
Financial Impact
A fulfillment center administrative coordinator earns $38,000–$52,000 annually. A VA providing comparable administrative support costs $1,200–$2,200 per month—savings of $23,000–$35,000 per year per position. For multi-merchant fulfillment centers, deploying one or two VAs to cover administrative operations can meaningfully reduce cost-per-order processed.
For fulfillment centers looking to scale merchant capacity without proportional administrative headcount growth, Stealth Agents provides virtual assistants familiar with fulfillment operations workflows and merchant billing administration.
