Zenventory

Zenventory is a purpose-built warehouse management system designed from the ground up for third-party logistics providers. Unlike generic inventory tools adapted for multi-client use, Zenventory natively supports segregated client inventory, white-label client portals, automated 3PL billing, and built-in multi-carrier shipping, all within one unified platform. Trusted by over 1,200 companies, Zenventory enables 3PLs to manage complex, multi-warehouse fulfillment operations without stitching together disconnected software tools or relying on spreadsheet workarounds.

The platform's standout capability is its integrated shipping engine, ZenShip, which connects to 10+ carriers including UPS, FedEx, USPS, DHL eCommerce, Amazon Shipping, GLS, OnTrac, and more. ZenShip automatically rate-shops every shipment before a label prints, delivers up to 90% off published rates, and consolidates all carrier billing into a single view.

Combined with barcode-driven pick, pack, and ship workflows, a free Android companion mobile app, and robust order automation with 40+ conditions and 15+ actions, Zenventory helps 3PLs reclaim up to 60 hours per week while maintaining 99%+ inventory accuracy and a 95%+ on-time delivery rate.

Zenventory differentiates itself with a pricing model that includes unlimited users, unlimited clients, unlimited products, and unlimited integrations on every plan, meaning 3PLs are never penalized for growth.

The platform also offers automated client billing that captures storage, handling, receiving, and accessorial fees as warehouse work happens. Additional capabilities include lot and serial number tracking, expiration date management with FIFO/FEFO controls, kitting and assemblies, vendor management with purchase orders and PAR levels, and a robust REST API.

Zenventory's support team is Phoenix-based and staffed by actual humans, with hold times that average under a minute during business hours. So you get enterprise-grade functionality without the enterprise-grade support runaround.
