Zenventory is the WMS built for multi-client 3PL operations. Inventory, orders, shipping, client billing, and client portals in one platform. No per-user fees. Up and running in weeks.
Trusted by warehouse operators and 3PLs across the U.S.
Sound familiar?
Running a 3PL means absorbing chaos so your clients don't have to. But most warehouse software was not built for operators like you. It was built for single-brand retailers.
When you force retail software into a complex, multi-client operation, the cracks show up fast:
Manual billing: Still reconciling accessorial charges in a spreadsheet at the end of the month. Every month.
No client portal: Your clients are emailing you at 10pm asking where their orders are – because they have no way to check for themselves.
Costly mix-ups: A new hire processed a batch of orders wrong because nobody told them Client C needs a different carrier. Completely avoidable ... but it happens.
Audit nightmares: A package goes missing, and now you're scrambling to prove it actually left your dock correctly.
Too many tools: You're paying for a separate shipping app and a separate billing tool, and manually stitching the data between them.
The right 3PL WMS does not make you work around these problems. It eliminates them.

BETTER BILLING WITH ZENVENTORY
One platform. Every 3PL workflow covered.
Zenventory was built specifically for multi-client 3PL operations. Not adapted from retail software. Not bolted together from separate modules. One platform that handles the full operation, from the moment inventory arrives to the moment a client invoice goes out.
EASIER CLIENT INVENTORY MANAGEMENT
Inventory control across every client and every location
Most 3PLs track client inventory in spreadsheets or in separate systems and reconcile the differences manually. Zenventory tracks each client's stock independently, with lot numbers, expiration dates, and location assignments, all in a single dashboard. You see everything. And each client sees only their own information.
FULFILLMENT ZEN
Order management built for 3PL complexity
Shopify, Amazon ... and every other channel your clients use feed into one fulfillment queue. Automation rules handle per-client routing, holds, and charges, triggering them the moment orders arrive. No one has to remember which client ships ground-only or which account gets a special handling fee.
REDUCE CLIENT INQUIRIES BY 70%
A self-serve client portal that answers the 10pm emails for you
Your clients get their own login. Where they can check inventory, order status, and tracking on their own. The "where is my order" emails stop because they already have the answer without you doing a thing.
AUTOMATE CLIENT BILLING
Automated 3PL billing that captures every billable event
Pick fees, storage by the cubic foot, special handling, packaging, every accessorial in your rate card. Zenventory logs each one as it happens and builds the invoice for you. At the end of the billing cycle, you review and send. No reconciliation spreadsheet. No charges that fell through because no one caught the condition.
A BETTER WAY TO SHIP
Built-in shipping and rate shopping (no third-party app required)
Compare rates, select carriers, print labels, and ship directly from Zenventory. No ShipStation. No EasyPost. No subscription stacking. Scan-based picking forces your team to confirm every item before a label prints, so when a client disputes an order, you have the audit trail to answer them.

MADE FOR 3PLS
The Zenventory platform
Multi-client inventory control
Every client's stock tracked separately, in one dashboard. Lot numbers, expiration dates, location assignments, all per client. No commingling.
Order management and fulfillment
POs, sales orders, and transfers in one workflow. Automation rules enforce per-client routing, holds, and charge triggers at order arrival, so the right logic applies without your team having to remember which client is which.
Built-in shipping and rate shopping
No separate shipping tool. Compare rates, pick the carrier, print the label, and ship directly from Zenventory. Scan-based validation means nothing leaves without your team confirming it first.
Automated 3PL billing
Set billing rates once per client. Zenventory captures pick fees, storage, and accessorials automatically. End of month, the invoices are ready to review and send, not rebuild from scratch.
Self-serve 3PL client portal
Clients log in with their own credentials and see their inventory, orders, and tracking. That is the end of most "where is my shipment" emails.
Multi-warehouse and multi-location management
Run inventory across multiple warehouse locations from one platform. Transfers, location assignments, and fulfillment routing work the same way whether you have one facility or five.
NO CONTRACTS. UNLIMITED USERS. UNLIMITED INTEGRATIONS.
Designed to scale with you, not charge you for growing
Most WMS platforms charge by the user. Add a warehouse manager, add a picker, add a customer service rep, and your bill grows with every seat. Zenventory does not price that way.
3PL operations are not static. Your headcount changes with volume. Your client count grows. You should not face a penalty every time your business improves.
No per-user fees. Transparent pricing. No surprise overage invoices at the end of the month.
NO CONTRACTS. UNLIMITED USERS. UNLIMITED INTEGRATIONS.
Up and running in weeks, not months
Enterprise WMS platforms sell you a vision and then hand you a six-month implementation timeline and a third-party consultant invoice.
Purpose-built for operations your size, we ditch the expensive consultants and pair you with a dedicated onboarding manager to make sure your setup is flawless before you go live.
The result? Most 3PLs are up and running in a matter of weeks. The platform is also so intuitive that new hires can be productive in just 15 minutes. If your current system requires a training manual, you already know the cost of that complexity.

Frequently Asked Questions (FAQs)
What is 3PL warehouse management software?
Third-party logistics providers manage inventory and fulfillment for multiple brand clients out of one or more warehouses. A WMS built for 3PL operations tracks each client's stock, orders, billing, and reporting separately, while giving the operator a single system to run the whole thing. Software designed for a single brand cannot do this without workarounds.
How is a 3PL WMS different from standard inventory software?
Most inventory tools were built for one business, one set of SKUs, and one billing relationship. When you run 10 clients out of one warehouse, that model breaks. A 3PL WMS keeps each client's inventory, billing rules, and order workflows completely separate. Automated 3PL billing, self-serve client portals, and per-client automation are native capabilities, not add-ons.
Does Zenventory support multiple warehouse locations?
Yes. Zenventory supports multi-location and multi-warehouse operations. Inventory is tracked per location, transfers between locations are managed within the platform, and fulfillment can be routed to the appropriate facility based on client rules or order conditions.
What is a 3PL client portal and does Zenventory include one?
A client portal gives each brand client a login to check their own inventory, orders, and tracking without emailing the warehouse. Zenventory includes one at no additional cost. Clients log in and see only their data, nothing else.
How does automated 3PL billing work in Zenventory?
You set a billing profile for each client: pick fees per unit, storage by cubic foot, packaging, special handling, and any accessorials in your rate card. From that point, Zenventory logs every billable event as it happens and builds the invoice for you. At billing time, you review and send. No reconciliation spreadsheet.
Can Zenventory handle order management for multi-channel 3PLs?
Yes. Zenventory connects to Shopify, Amazon (FBA and FBM), and other channels. Orders from all sources flow into a unified fulfillment queue. Automation rules handle per-client routing, holds, ship-via assignments, and charge triggers at the moment orders arrive.
Does Zenventory have built-in shipping or does it require a third-party app?
Zenventory includes native shipping capabilities. You compare carrier rates, select a service, print labels, and fulfill orders entirely within the platform. No connection to ShipStation, EasyPost, or any other third-party shipping tool is required, though integrations are available.
How long does it take to implement Zenventory?
Get your 3PL live in weeks, not months. With Zenventory, there is no six-month rollout and no need to hire an expensive third-party implementation consultant. If you understand your workflows, you can easily configure the platform, bring clients on board, and start fulfilling orders.
You won't be doing it alone, either. We provide a dedicated onboarding manager to partner with you every step of the way, ensuring everything is set up perfectly before you ever go live.
Does Zenventory charge per user?
No. Zenventory does not charge per-user fees. Your pricing does not increase because you added a warehouse associate or a new operations manager. This makes Zenventory especially well-suited for 3PLs with variable headcount or growing teams.
What scan-based workflows does Zenventory support?
Zenventory's mobile app and barcode scanning support enforce scan-based validation at receiving, picking, packing, and shipping. Staff must scan items before a shipping label is generated, creating a granular audit trail that documents who scanned what, when, and where. This is the primary defense for 3PLs when clients dispute a shipment or claim a wrong item.
How does Zenventory compare to enterprise WMS platforms?
With enterprise WMS platforms, getting one off the ground takes months, and you'll probably need to bring in an outside consultant just to configure it.
Zenventory isn't trying to be that. You get a dedicated onboarding manager (not a third-party consultant), and your 3PL is typically fully live in a few weeks.
Pretty simple way to think about it: If you're trying to grow from 5 clients to 25 – rather than from 25 facilities to 50 – Zenventory is probably the better fit.
