MULTI-CHANNEL. MULTI-WAREHOUSE. ACCURATE INVENTORY. 

Real-time inventory tracking across warehouses & clients

To run a modern 3PL, you need to see what's happening the moment it happens. Zenventory's inventory software gives you the power by allowing you to:

  • Track inventory by client, SKU, lot, or warehouse: See your stock levels organized by client, item, lot number, or specific warehouse location.
  • Know your real numbers: View exactly what you have in stock, what’s already promised to customers, and what’s ready to ship in real time.
  • Stop overselling: Prevent selling items you don't have across all your different platforms, marketplaces, and locations.

  • Monitor your stock across warehouses: Keep an eye on how items are moving from one warehouse to another.
  • One centralized dashboard: Manage all your different warehouse locations from a single, central dashboard.

ENSURE COMPLIANCE. MINIMIZE SPOILAGE. 

Lot, expiration & FIFO/FEFO controls 

Many 3PLs manage food, supplements, cosmetics, or regulated products. Basic quantity tracking isn’t enough.

Zenventory’s 3PL inventory management system includes:

  • Lot number tracking by client: Keep track of specific batches (lot numbers) for every client.

  • Expiration date monitoring: Automatically monitor when products are going bad so you can move them out in time.

  • Smart shipping rules (FIFO): Use "First-In, First-Out" logic to make sure the oldest stock you received gets shipped first.

  • Smart shipping rules (FEFO): Use "First-Expired, First-Out" rules to prioritize shipping items that will expire soonest.

  • Lot-level reporting and traceability: Get detailed reports on any specific batch to see exactly where it came from and where it went.

This ensures compliance, minimizes spoilage, and protects your clients from costly recalls or expired shipments.

ENTERPRISE-LEVEL VISIBILITY WITHOUT THE ENTERPRISE-LEVEL COST

Multi-client architecture built for 3PL complexity

Most inventory systems are designed for single-brand businesses.

Zenventory is different.

We built our platform specifically for 3PLs to help you handle multiple clients at once:

  • Segregated client inventory: Organize and store each client’s inventory in its own secure space.

  • Client-specific billing rules: Set up unique billing rules for every client so you never miss a charge.

  • Role-based permissions: Give your team members specific access levels based on their jobs.

  • White-label client portals: Give clients a dedicated login area featuring your own branding.

INCREASE YOUR MARGIN

Integrated shipping:
Why disconnected systems kill accuracy

Most 3PLs try to manage inventory in one system and shipping in another. This usually leads to:

  • Sync delays: Your systems don't talk to each other fast enough.
  • Double entry: You have to enter the same data twice.
  • Reconciliation errors: Your numbers don't match up, leading to errors.
  • Margin blind spots: It’s hard to see your true costs and margins.

Zenventory includes built-in shipping (ZenShip), allowing inventory, order management, and shipping to operate within one platform.

When labels are created, inventory updates instantly.

That’s operational zen, not patchwork software.

INVENTORY MANAGEMENT, SIMPLIFIED

The ultimate solution for accurate inventory

Zen Logo
Item management

Easily import your initial items, including item numbers, SKUs, UPC, EAN, category, and initial stock levels to get up and running fast. Set up multiple units of measure and create variants. Upload one or more pictures per item. Assign to one or more warehouses and set re-order levels per warehouse. Manage lot numbers, serial numbers, and expiration dates.
Zen Logo
Cycle counting

Cycle counting is an effective and accurate best practice for warehouse maintenance. Cycle counting helps you avoid shutting down your warehouse to complete a wall-to-wall inventory count, saving you time and money. Use our app to perform counts of locations based on selected criteria.
Zen Logo
Receive & put away goods

Use a computer, tablet, or mobile app to efficiently receive goods and store them in warehouse locations. Lot numbers and expiration date records are captured during the receiving process, and default locations can be set. Stock can easily be relocated or split up to multiple locations to improve picking efficiency.
Zen Logo
Picking/order allocation automation

Streamline your inventory and order management process with allocation rules, pick/pack workflows, and dynamic order tagging. Whether you fulfill from a single location or operate a distributed network, Zenventory handles the logic so you don’t have to.
Zen Logo
Par levels

Inventory is expensive - you want to avoid unnecessary stock on hand. Known as the item’s “par level,” Zenventory calculates the “sweet spot” of quantity to keep on hand to fulfill orders and allow lead time for reordering. That way, you avoid having excess products stored on the shelves (that could be money in the bank).
Zen Logo
Low stock alerts & more

Get notified by email when your stock reaches minimum levels, expiration dates are approaching, and when it is depleted. Zenventory can send SMS text messages to key personnel as well. All messages are completely customizable and can be sent to specific Zenventory users, vendors, 3PL clients, customers, and more.
Zen Logo
Kits & bundles

Simplify the fulfillment process with products that have bills of material (BOM) with an automated breakdown of components needed for built-to-order products. 
Zen Logo
Assemblies

Effortlessly create work orders, efficiently manage assembly tasks, track your inventory of finished goods and materials, and even ship out your orders. 
Zen Logo
Lot/batch tracking & expiration management

Manage perishable items and high-compliance SKUs with expiration dates tracking, lot tracking, and recall-ready visibility. Secure traceability from receipt to shipment - so you can quickly identify affected units in the event of a recall.
Zen Logo
Multiple views

Review inventory by warehouse and location. Filter by vendor. Identify low and expiring stock. Calculate buildable kits. Search by SKU, description, or category.

Frequently Asked Questions (FAQs)

What is 3PL inventory management software?

3PL inventory management software is a warehouse management system designed specifically for third-party logistics providers to track inventory across multiple clients, warehouses, and fulfillment workflows in real time.

How does an inventory management software like Zenventory work?

Inventory control platforms like Zenventory provide a centralized system for real-time tracking of inventory, purchase orders, and warehouse activities. It features barcode scanning, automated replenishment, and integrations with sales and shipping systems to reduce errors and increase efficiency. 

Any "good" inventory management system, like Zenventory, also provides detailed analytics and reports to help businesses keep the right stock levels and improve order fulfillment. 

Is there a difference between inventory management software and a warehouse management system?

The primary goal of inventory management software is to track inventory and ensure that businesses maintain the perfect stock levels at all times.

On the other hand, a warehouse management system (WMS) goes beyond inventory tracking and encompasses a wide range of tasks, including order fulfillment and optimizing warehouse operations.

Don't know how to choose between the two? You're in luck! Some solutions, like Zenventory, offer both inventory and warehouse management functionality, allowing users to get the best of both worlds.

Does Zenventory have an API?

Yes! Zenventory enables API access on ALL plan tiers, so you can get updated inventory quantities, make stock adjustments, or request transfers from other warehouses by API.  

Zenventory even supports no-code API integration to over 7,000 apps with Zapier.
