Multi-Carrier Shipping Built for 3PLs

Automatic rate shopping across 10+ carriers

Before any label prints, Zenventory checks every connected carrier against your configured rules. The qualifying option with the lowest rate wins. Your staff does not choose a carrier. The system does.

Carrier tiers for every shipment type

Not every package needs UPS Next Day. Not every client accepts a 6-day transit. Zenventory's carrier tiers let you route by service level, cost target, and client requirement — set once, applied to every shipment automatically.

One invoice for all 10+ carriers

All carrier billing flows into a single Zenventory view. Residential vs. commercial misclassifications are flagged. Overcharges are surfaced. Month-end carrier reconciliation goes from a four-hour exercise to a 20-minute review.

Return labels at your outbound rates

Generate return labels for customers across all 10+ carriers at the same negotiated rates you use for outbound shipments. Your clients' customers get a professional return experience. You do not pay retail.

Inventory sync

With Zenventory connected to all your platforms and marketplaces, automated inventory syncing keeps every sales channel updated with the same accurate stock levels. That way, you're always in control. (optional, you can turn this on and off). 

Built for the warehouse

The Zenventory UI is purpose-built for ease of use and efficiency in real-world warehouse settings. And since all Zenventory plans include unlimited user accounts, the whole team gets to reap the benefits.

Batch/lot number tracking

Zenventory tracks lot numbers from the time they are received through their storage life cycle and all the way to the customer who receives them at the end of the process. Our reporting also keeps you compliant and ready for recalls. 

Kitting/assemblies

Serial numbers (for high-value items & electronics)

Track every item you sell individually. Zenventory logs and tracks serial numbers per unit when inventory is received and shipped to the customer.

Expiration dates (with timely alerts for expiring stock)

Zenventory fully supports expiration dates and can prevent you from accidentally sending out expired products. Zenventory's allocation rules can also assign inventory to support a FEFO strategy automatically (first expiring, first out).
