Client-scoped inventory
Every item belongs to a client. Permissions, portals, and reports respect that scope automatically.

Boutique 3PL Software: Multi-Client Inventory Without the Enterprise Bloat
Boutique 3PL software for operators who serve a handful to a few dozen clients with high-touch service. Multi-client inventory, per-client portals, per-client billing, and white-label branding, without the enterprise WMS price tag.
Definition
What is boutique 3PL software?
Boutique 3PL software is the operations platform small and mid-sized third-party logistics providers use to run multi-client warehousing. Unlike enterprise WMS systems built for tens of thousands of SKUs and IT-led rollouts, boutique 3PL software is built for operators who want every new client onboarded in a day, a client portal that looks like their own brand, and billing that runs itself.
The defining capabilities are simple: every item belongs to a specific client; every client gets a scoped, branded portal; and every client is billed independently with their own recurring schedule and saved payment method. From the back office, your team works one warehouse across every client. From the front, each client experiences a private operation built around them.
Stowley is boutique 3PL software built around exactly that shape. You skip the implementation invoice, the consulting engagement, and the six-month rollout, and you get the multi-client structure, portal, and billing your accountant and your clients both want.
Capabilities
Key capabilities
One operations workspace
Your team works one warehouse → zone → aisle → bin hierarchy across every client. No app switching.
Inbound, pull, shipping & delivery flows
Inbound, pull, shipping, and delivery all flow through one unified Service Requests page. Shipping requests rate-shop carriers and buy labels through built-in ShipStation, with tracking and label PDFs attached automatically.
ShipStation built in
Connect your ShipStation API key once. Every shipping request gets live multi-carrier rate-shop, one-click label purchase as a PDF or thermal label, parcel presets, and automatic tracking-number capture. Postage can be billed back to the client with your markup.
Shopify & Amazon order sync
Orders from your clients' Shopify, Amazon, and other stores that you ship in ShipStation flow back on their own. Each label becomes a completed shipping request, the shipped SKUs are checked out of that client's inventory, and anything that does not match is flagged for review.
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 Premium and Enterprise, each client sees a portal carrying your logo and brand. Your customers' customers experience your operation.
Top-client and aging reports
Revenue, aging, and category breakdowns by client. Know who's profitable, who's slipping, and where volume concentrates.
QuickBooks & Xero exports
Invoices export in the layout of QuickBooks Online's invoice import and Xero's sales invoice template, plus a payments file keyed to each Stripe deposit. Your accountant gets last month's files by email on the 1st.
Webhooks & client data feeds (Enterprise)
Signed webhooks when an invoice is paid, a request changes, or stock arrives, and a read-only inventory feed per client as JSON or CSV. Zapier, Make, and in-house systems plug straight in.

FAQ
Frequently asked
What is boutique 3PL software?
Boutique 3PL software is the operations platform small and mid-sized third-party logistics providers use to run multi-client warehousing without the cost, complexity, or implementation overhead of enterprise WMS systems. It segregates inventory by client, gives each client their own branded portal, and bills them independently, all from one workspace.
Is Stowley a good fit for a small or boutique 3PL?
Yes. Stowley is built for boutique 3PLs and white-glove logistics operators who serve a handful to a few dozen clients with high-touch service. You get multi-client inventory, per-client portals, per-client billing, and white-label branding without paying enterprise prices or running a six-month rollout.
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, so there's no way for one client to see another's stock.
Can each client get their own branded portal?
Yes, on the Premium and Enterprise plans. The portal is white-labeled per account with your logo, favicon, brand color, and reply-to email. Every client sees a portal that reinforces your operation as their logistics partner.
Can we bill clients on different schedules?
Yes. Recurring billing is configured per client: different billing days, different rates, different payment methods on file. Each client's invoices and ledger are independent and auto-pay through Stripe.
How is boutique 3PL software different from enterprise WMS?
Enterprise WMS platforms are built for tens of thousands of SKUs, custom integrations, and IT teams. Boutique 3PL software is built for operators who want every client onboarded in a day, a portal that looks like their own brand, and billing that runs itself. You skip the implementation invoice and the consulting engagement.
