The blind spot

Your control tower sees the shipment. Not the stock.

Control towers track orders, shipments and warehouse stock. Once stock reaches a hospital, a site, a van or a technician, the screen goes quiet. Your client still holds you accountable for it.

Stock goes dark after delivery
Consigned stock, site stock and technician parts sit outside every 3PL's WMS. Nobody sends that data to your control tower.
One client, many 3PLs, many methods
Each 3PL tracks field stock its own way. In our 2026 survey of 312 3PL professionals, 71% relied only on phone, email and spreadsheets.
Costly surprises for your clients
73% of 3PLs in the same survey sent emergency freight in the past year for stock they already owned. The bill lands on your client. The question lands on you.
No time to build it yourself
Building a field inventory platform takes years. Adding Ventory to your service takes 4-8 weeks, with a proven enterprise product.

Platform capabilities

Everything a 4PL needs to run field stock for its clients.

One platform across every client and every 3PL in their network, with the integrations and security enterprise shippers expect.

One view across every 3PL
Every 3PL in a client's network scans into the same platform. One live stock number per location, whoever runs it.
Multi-client management
Each client gets its own secure environment. Manage stock for all your clients from one partner view, fully segregated.
ERP and WMS integration
Connect the client's ERP once: SAP, Oracle, Dynamics, Sage or NetSuite. No change to any 3PL's WMS.
Beyond the warehouse
Consigned stock, site stock, engineer vans, technicians and forward stocking locations, tracked in real time.
Works fully offline
The mobile app keeps working at remote sites without a signal and syncs when the connection returns.
Secure by design
ISO 27001 certified, SOC 2 and GDPR compliant. Role-based access per location and a full audit trail of every scan.

Frequently asked questions

What does Ventory offer 4PLs?

One live stock view for each client, across every 3PL you manage. Beyond the warehouse: consigned stock, site stock, engineer vans and spare parts with technicians. You add it to your service. We run the platform.

Do the 3PLs need to change their WMS?

No. Each 3PL keeps its own WMS. Field teams scan into Ventory on iOS or Android, online or offline. Ventory syncs with the ERP your client already runs: SAP, Oracle, Dynamics, Sage or NetSuite.

Is Ventory secure enough for enterprise shippers?

Yes. Ventory is ISO 27001 certified, SOC 2 compliant and GDPR compliant. It runs today for a national ambulance service, a global 3PL and a global consumer-goods company.

How is this different from our control tower?

Your control tower sees orders and shipments. Ventory shows the stock after it lands: at hospitals, sites, depots and in vans. It feeds your tower with live stock data instead of replacing it.

How do we start?

With a discovery call, then a demo on one of your clients' scenarios. Then a focused-scope deployment: one client, one site group, live in 4-8 weeks.

Which industries is this built for?

Industries where stock lives outside the warehouse: medtech (consigned implants, loaner kits), field service (van stock, spare parts), energy and utilities (site stock) and defence (depot and base stock).

Ready to see beyond the warehouse?
