Turn Your Warehouse Into a Revenue-Generating 3PL
You already have the space, the team, and the know-how. What you're missing is the software that lets you onboard clients, manage their inventory separately, and bill accurately — without cobbling together five different tools.
Is this you?
There's a $200B Fulfillment Industry, and Most of It Runs on Chaos
eCommerce brands are desperate for reliable fulfillment partners. The ones that have tried the mega-3PLs got burned. The ones doing it themselves are drowning. There's a massive gap in the middle — and you're sitting on the warehouse space to fill it.
The Market Is Exploding
eCommerce fulfillment is growing 10-15% year over year. DTC brands are launching daily, and most of them need a fulfillment partner within 12 months of hitting 100 orders/day. That demand isn't going anywhere.
Your Space Is Underutilized
If you're running a warehouse at 60-70% capacity, you're paying for 30% dead space. Adding fulfillment clients turns that overhead into recurring revenue — without adding square footage or a new lease.
Brands Want Boutique
After being a number at a mega-3PL, brands crave personal service, transparency, and a partner who picks up the phone. Small and mid-size 3PLs are winning deals the big players can't — because they actually care.
What a Single Client Could Look Like
A mid-size DTC brand shipping 2,000 orders/month:
Warehouse Space Is the Easy Part. Managing Multiple Clients Is Where It Falls Apart.
You know how to ship. But running a 3PL means keeping every client's inventory separate, billing accurately, onboarding quickly, and giving clients visibility — without your team losing their minds.
The Client Isolation Problem
Client A's inventory gets mixed with Client B's. Orders from one store accidentally ship with another client's packing slip. Your team is toggling between accounts, spreadsheets, and logins — and every context switch is an error waiting to happen.
What this costs you: One cross-client shipment error can destroy a relationship. The client doesn't see an accident — they see incompetence.
The Billing Nightmare
How many picks did you do for each client last month? How many pallet positions did they use? How many receiving hours? If you can't answer those questions instantly, you're either undercharging (losing money) or sending invoices your clients don't trust.
The ugly truth: Most small 3PLs leave 15-25% of billable activity on the table because they can't track it.
The Onboarding Bottleneck
A new client says "yes." Now what? You need their product catalog, SKU mappings, shipping preferences, store connections, and special handling rules. Without a system, this takes weeks of emails, spreadsheet imports, and manual setup. Meanwhile, the client is wondering if they made the right choice.
The Visibility Gap
Your clients want to see their inventory levels, order status, and shipment tracking in real time. If the only way they get that information is by emailing you and waiting for a response, you're losing to every 3PL that offers a client portal. Transparency isn't a nice-to-have — it's table stakes.

Design My WarehouseYou Don't Need Enterprise Software. You Need a WMS That Was Built for 3PLs From Day One.
Most warehouse software was built for single-tenant operations and bolted on "multi-client" as an afterthought. CannonWMS was architected from the ground up for operators managing multiple brands under one roof.
How Other 3PLs Operate
How CannonWMS 3PLs Operate
"We onboarded three new clients in our first month with CannonWMS. Used to take us two weeks per client — now it's same-day."
Every Feature a 3PL Needs — Nothing You Don't
CannonWMS isn't a generic WMS with a multi-client checkbox. It's built for operators who manage multiple brands, multiple channels, and need their clients to trust them completely.
Isolated Client Workspaces
Each client gets their own database, users, channel connections, and configuration. No data bleed, no cross-contamination. Switch between clients instantly from one operator dashboard. Full audit trails per account so you can prove exactly what happened and when.
Visual Client Onboarding
Connect a new client's Shopify store via OAuth and browse their full product catalog with images, variants, and SKUs. Select only the products you'll fulfill — not the entire catalog. Already-imported items are flagged to prevent duplicates. From handshake to shipping in hours, not weeks.
Branded Client Portal
Give each client a self-service portal branded to your 3PL. They log in, see their inventory levels, order status, shipment tracking, and receiving history — without calling you. Reduces support tickets, builds trust, and makes your operation look enterprise-grade.
Automatic Inventory Sync
As you receive, put away, and ship client inventory, stock levels push automatically to their Shopify locations. Their storefront always shows accurate availability. No manual updates, no oversells, no "let me check and get back to you" emails.
Proactive Reorder Alerts
CannonWMS tracks 30-day sales velocity for every client SKU and calculates stock runway. When a client's product is running low, you know before they do. Trigger a replenishment PO or send an automated alert — that kind of proactive service is how you retain clients for years.
Activity-Based Billing Data
Every pick, pack, ship, receive, and storage event is logged per client. Pull billing reports instantly — picks by SKU, storage by pallet position, receiving hours, shipping volume. No more end-of-month guesswork. Your clients trust the numbers because the system generated them.
