ENGINEERED TO ELEVATE YOUR OPS

A better way to manage your inventory

Multi-channel inventory sync

Stop showing "out of stock" when the product's sitting on your shelf. Make sure your stock is updated across all platforms, so customers see exactly what you have. No more overselling. No more stockout mix-ups.

Multi-warehouse ready

Manage inventory across multiple warehouses. Choose items for each warehouse, connect marketplaces for order fulfillment, designate shipping strategies, and easily transfer inventory to maintain balance.

Barcode-driven workflows

Scan items during receiving, picking, transfers, and cycle counts to keep inventory accurate in real time. Every movement updates instantly, so stock levels stay precise, errors stay low, and client trust stays high.

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.

INVENTORY MANAGEMENT, SIMPLIFIED

The ultimate solution for accurate inventory

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.

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.

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.

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.

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).

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.

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.

Assemblies

Effortlessly create work orders, efficiently manage assembly tasks, track your inventory of finished goods and materials, and even ship out your orders.

Lot/batch tracking & expiration management

Manage perishable items and high-compliance SKUs with expiration date 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.

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.

What is multi-client inventory management?

Multi-client inventory management lets a 3PL track stock, fulfillment rules, and billing separately for each client — all from one platform. Each client's inventory is isolated: they can't see each other's data, and their billing rules, pick workflows, and portal access are all configured independently. Zenventory handles this natively, not through workarounds.

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.

Is Zenventory the right 3PL inventory management software for you?

Zenventory is ideal for:

• Small to medium sized 3PLs managing multiple clients
• Multi-warehouse fulfillment operations
• 3PLs transitioning from spreadsheets
• Teams replacing disconnected WMS + shipping tools
• Growing logistics providers protecting margin

If you’re searching for scalable 3PL inventory management software without enterprise pricing complexity, Zenventory was built for you.

How is 3PL inventory management different from regular inventory software?

3PL software must support multi-client segregation, complex billing rules, warehouse transfers, client portals, and real-time integrations, which standard retail inventory systems do not handle effectively.

Does Zenventory support multiple warehouses?

Yes. Zenventory supports unlimited warehouse locations with centralized visibility and location-level control.

Can Zenventory handle lot tracking and expiration dates?

Yes. Zenventory supports lot tracking, expiration monitoring, FIFO, and FEFO fulfillment logic.

How does Zenventory improve inventory accuracy?

Through barcode-driven workflows, real-time updates, automated workflows, and integrated shipping functionality.
