Last-mile delivery is the most expensive and operationally complex segment of the supply chain, accounting for an estimated 53 percent of total shipping costs according to McKinsey's research on last-mile economics. In 2026, as e-commerce volumes continue to grow and merchant expectations for delivery transparency increase, last-mile delivery operators are under pressure to improve both billing efficiency and driver workforce management — without proportionally increasing operating costs.
Virtual assistants are emerging as a key lever for last-mile companies seeking to manage administrative complexity without expanding fixed headcount.
Delivery Fee Billing for Merchant Shippers
Last-mile delivery billing involves more complexity than a simple per-package rate. Merchant shippers are billed on delivery attempt counts, successful delivery rates, zone-based pricing, fuel surcharges, and accessorial charges for returns, re-delivery attempts, and oversized packages. Producing accurate invoices from high-volume delivery data requires systematic reconciliation.
Virtual assistants trained in delivery billing workflows can pull delivery data from dispatch systems, apply contracted rate schedules, generate itemized invoices, and send billing packages to merchant accounts on schedule. They also handle billing disputes — researching specific delivery events when merchants contest charges — without pulling operations managers into time-consuming case resolution.
FreightWaves has reported that billing disputes are a significant source of merchant churn in the last-mile sector, making accurate, timely invoicing a retention priority, not just a finance function.
Merchant Shipper Account Administration
Each merchant shipper account requires ongoing administrative management: onboarding new shipping locations, updating delivery address whitelist configurations, processing volume commitment changes, and managing integration credentials for order management system connections. As last-mile operators grow their merchant base from dozens to hundreds of accounts, this administrative surface area expands rapidly.
Virtual assistants maintain merchant account records, process configuration change requests, coordinate new location setups with operations teams, and manage the documentation required for new merchant onboarding. Dedicated account managers can focus on relationship development and volume growth rather than administrative backlog.
Driver Onboarding: Speed as a Competitive Requirement
Last-mile delivery companies depend on large, frequently replenished driver workforces — gig drivers, independent contractors, and employed couriers. Driver onboarding requires background check coordination, vehicle insurance verification, app account setup, training completion tracking, and payment method enrollment. In high-turnover delivery markets, the speed of driver activation directly affects capacity availability.
According to Gartner's research on gig workforce management, companies with streamlined contractor onboarding processes achieve driver activation in 24 to 48 hours, compared to industry averages of five to seven days for companies relying on manual processes.
Virtual assistants manage driver onboarding workflows: sending document request packages, following up on missing items, coordinating background check status, and notifying operations when drivers are cleared for dispatch. The result is a faster pipeline from driver application to active status.
Driver Account Maintenance and Compliance Tracking
Active driver management requires ongoing administrative attention beyond initial onboarding. Insurance renewal reminders, vehicle registration expiration tracking, app re-credentialing for policy updates, and payment dispute resolution are recurring tasks that consume dispatch and operations staff time.
Virtual assistants maintain driver compliance calendars, send proactive renewal reminders, flag expiring documents before they become compliance gaps, and process routine payment inquiries. This keeps the active driver fleet in compliance without requiring dispatch teams to double as HR administrators.
Returns Processing and Reverse Logistics Billing
Returns are an increasingly large component of last-mile delivery operations, particularly for e-commerce merchants with high return rates in apparel and electronics. Returns pickups require separate billing workflows — per-return fees, label generation coordination, and merchant credit reconciliation — that are distinct from outbound delivery billing.
Deloitte's analysis of reverse logistics operations has highlighted administrative complexity as a major cost driver in returns management, particularly for last-mile operators handling returns for multiple merchant accounts simultaneously.

Scaling for E-Commerce Volume Growth
E-commerce growth shows no structural ceiling in 2026, and the last-mile operators capturing share are those that can scale merchant accounts and driver capacity without corresponding back-office headcount growth. Virtual assistants provide the administrative infrastructure that makes this scaling possible.
