Last-mile delivery — the final leg of a shipment's journey from a distribution center to the customer's door — is both the most visible and the most operationally complex segment of the delivery chain. McKinsey & Company estimates that last-mile delivery accounts for 41 to 53 percent of total supply chain costs, driven by the density challenges of residential delivery, high failed-delivery rates, and the labor intensity of managing large delivery driver networks. In 2026, last-mile operators are turning to virtual assistants to reduce the administrative overhead that compounds these inherent cost pressures.
Why Last-Mile Operations Need Administrative Support
A regional last-mile delivery company handling 500 to 2,000 deliveries per day operates a complex daily cycle. Routes must be planned and dispatched, drivers must be briefed and tracked, customer delivery windows must be communicated, exceptions must be managed in real time, and failed deliveries must be rescheduled. After the day's routes complete, delivery confirmations must be reconciled, client invoices must be generated, and driver performance data must be logged.
This operational and administrative cycle repeats every day, and for small to mid-size last-mile operators, it typically falls on a handful of operations staff who are simultaneously managing driver calls, exception escalations, and client communications. Virtual assistants provide structured support for the administrative components of this cycle, allowing operations staff to focus on the real-time decisions that keep deliveries moving.
Dispatch Support and Route Communication
Virtual assistants in last-mile operations handle several dispatch-adjacent functions. Before routes launch, VAs confirm driver availability, communicate route assignments and any special delivery instructions, and verify that customer contact information in the routing system is current. During active delivery windows, they manage inbound customer inquiries about delivery status, relay exception information from drivers to clients, and coordinate redelivery scheduling for failed attempts.
The Bureau of Labor Statistics (BLS) reports that last-mile delivery employment grew by over 18% between 2022 and 2025, but driver turnover rates in the sector remain high — often exceeding 70% annually. This turnover creates continuous onboarding and communication load for operations teams. VAs support new driver orientation by sending route briefing documents, collecting required documentation, and maintaining driver records in the company's fleet management system.
Customer Communication and Exception Handling
Customer expectations for last-mile delivery have been shaped by the experiences of Amazon, FedEx, and UPS — real-time tracking, proactive exception notifications, and same-day redelivery scheduling. Regional last-mile operators competing for e-commerce shipper contracts must match these service standards.
Virtual assistants manage the customer communication layer: sending pre-delivery notification messages, responding to delivery status inquiries via email and chat, processing address correction requests, and handling post-delivery complaints or damage claims. The National Retail Federation (NRF) reports that failed delivery management — communicating with customers and scheduling redeliveries — accounts for a disproportionate share of last-mile customer service costs. VAs handling this function reduce the per-exception cost significantly.
For delivery-as-a-service contracts with e-commerce retailers, VAs maintain the client communication cadence — providing daily delivery summaries, exception reports, and weekly performance data — that supports contract compliance and renewal.
Billing, Invoicing, and Client Reconciliation
Last-mile billing involves per-stop rates, zone-based pricing, residential delivery surcharges, failed attempt fees, and account-specific rate agreements. For a company serving multiple e-commerce clients simultaneously, billing complexity multiplies with each account.
Virtual assistants trained in last-mile billing generate invoices aligned with each client's rate agreement, apply applicable surcharges and adjustments, attach delivery confirmation data, and submit invoices on the client's required billing cycle. They monitor accounts receivable and follow up on outstanding invoices on defined schedules.
McKinsey's supply chain research notes that last-mile operators with automated or well-structured billing processes collect payment 15 to 20 days faster than those with manual, error-prone billing workflows — a cash flow impact that is material for asset-intensive delivery companies operating on thin margins.
Performance Data and Client Reporting
E-commerce clients contracting with last-mile providers demand performance visibility: on-time delivery rates, first-attempt success rates, customer satisfaction scores, and exception rates by route or zone. Virtual assistants compile this data from routing software and delivery management platforms such as Bringg, Onfleet, or Circuit, format it into client report templates, and distribute reports on weekly or monthly schedules.
Consistent, data-backed reporting supports contract renewals and justifies rate discussions — making VA-supported reporting a revenue protection function, not just an administrative one.
The Scalability Advantage
Last-mile volume is seasonal and event-driven, with significant spikes around holidays, promotional events, and product launches. A VA support model allows last-mile operators to scale administrative capacity during peak periods without the cost and complexity of seasonal hiring. VAs working extended or split-shift schedules can also provide coverage during evening delivery windows when customer inquiries peak.
Last-mile delivery companies looking to reduce administrative overhead and improve client service metrics can explore trained VA solutions through Stealth Agents, which provides virtual assistants experienced in delivery operations and logistics.
