Third-party logistics (3PL)

Boutique 3PL Software: Multi-Client Inventory, Portals & Billing

Boutique 3PL software that segregates every client's inventory, gives each their own branded portal, and bills them automatically — all from one operations workspace. The 3PL software your accountant and your clients will both thank you for.

Built for third-party logistics (3pl)

Every capability below ships in Stowley today — no add-ons, no roadmap promises.

Client-scoped inventory

Every item belongs to a client. Permissions, portals, and reports respect that scope automatically — no manual filtering, no leaked visibility.

One operations workspace

Your team works one warehouse → zone → aisle → bin hierarchy across every client. Move, transfer, and locate without switching apps.

Inbound, pull, shipping & delivery workflows

Inbound, pull, shipping, and delivery all flow through one unified Service Requests page. Shipping requests rate-shop carriers and buy labels through the built-in ShipStation integration, with tracking numbers and label PDFs attached automatically.

Per-client invoicing & auto-pay

Each client has their own recurring invoice schedule and saved Stripe payment method. Bill 50 clients on the 1st without lifting a finger.

White-label per account

On Enterprise, each client sees a portal carrying your logo and brand. Your customers' customers experience your operation, not a generic SaaS.

Top-client and category reports

See revenue, aging, and category breakdowns by client. Know who's profitable, who's slipping into past-due, and where your volume is concentrated.

Frequently Asked

The questions operators in this space ask us most often.

How do you keep client inventories separate?
Every item is owned by a specific client, and access controls enforce that scope. Client portals are scoped to that client's items only — there's no way for one client to see another's stock.
Can we bill clients on different schedules?
Yes. Recurring billing is configured per client — different cadences, different rates, different payment methods on file. Each client's invoices and ledger are independent.
Can each client get their own branded experience?
On the Enterprise plan, the portal is white-labeled with your logo, favicon, brand color, and reply-to email. Every client sees a portal that reinforces your operation as their logistics partner.
How do we handle inbound shipments from clients?
Clients submit inbound requests from their portal with carrier, tracking, and expected contents. Your team receives the shipment, logs each item, and the request closes with full audit history.
Do you integrate with ShipStation?
Yes. Connect your ShipStation v2 API key on Account Settings → Integrations, and shipping service requests get live multi-carrier rate-shop, one-click label purchase, and automatic tracking-number capture. Save reusable parcel presets so your team doesn't re-enter the same box dimensions every shipment.
Can we report on revenue per client?
Yes. Reports break out revenue, aging, and category mix by client, so you can see your top accounts, your slow-pay accounts, and where your volume is coming from at a glance.
