PrepVia OS - 2026 Pricing, Features, Reviews & Alternatives

PrepVia OS is a proprietary, cloud-based warehouse management system (WMS) built to power Amazon FBA prep and fulfillment operations for e-commerce sellers and 3PL providers. The platform centralizes inbound shipment processing, inventory tracking, FBA labeling, bundling, and outbound logistics into a single operational environment, eliminating the need for disconnected spreadsheets or manual workflows across warehouse teams.

PrepVia OS supports the full FBA prep lifecycle, from receiving and inspection through kitting, polybagging, labeling, and carrier-ready shipment creation. The system provides real-time inventory visibility across SKUs and storage locations, with role-based access controls that allow warehouse staff, account managers, and clients to interact with relevant data at appropriate permission levels. Client-facing portals give sellers direct visibility into their inventory status, prep progress, and shipment history without requiring manual reporting from warehouse teams. Integration with Amazon Seller Central allows shipment plans and FBA requirements to be pulled directly into the workflow, reducing compliance errors and rework.

Designed for growing 3PL operations and high-volume FBA sellers, PrepVia OS scales across multi-client warehouse environments. Billing and invoicing modules are built into the platform, automating fee calculation based on configurable prep service rates, storage duration, and unit volumes. Reporting tools surface operational throughput, client activity, and cost-per-unit metrics, giving operators the data needed to optimize staffing, pricing, and capacity. PrepVia OS positions warehouse operators to run leaner, more transparent FBA prep businesses without reliance on generic WMS tools not designed for Amazon's compliance requirements.
