Real-Time Inventory Visibility: Why Only 6% of Companies Have It
Only 6% of companies have full supply chain visibility, and inventory distortion costs retailers $1.7 trillion a year. Here is why inventory visibility breaks outside the warehouse and how to get it in real time in 4-8 weeks.
Only 6% of companies can see their whole supply chain
Inventory visibility is knowing what stock you hold, where it is, and in what state, right now. It sounds basic. Almost nobody has it. Only 6% of organisations report full end-to-end supply chain visibility, and 23% of supply chain leaders admit they cannot access inventory that physically exists somewhere in their network.
The gap is expensive. Inventory distortion, the combined cost of stockouts and overstocks, costs retailers around $1.7 trillion a year. Real-time inventory visibility is the fix, and the hardest place to get it is exactly where the stock matters most: outside the warehouse.
Why visibility breaks outside the four walls
Inside the warehouse, visibility is close to solved. Fixed scanners, racking and a WMS keep the count accurate. The moment stock moves into the field, the picture goes dark.
In field-heavy industries, 20-40% of finished-goods inventory lives outside the warehouse: on consignment, in loaner kits, in engineer vans, in ambulance boots, at customer sites. That stock has the worst data and the highest stakes. The reasons are always the same:
- The ERP only sees what shipped. It has no real-time view of what is left at a customer site today.
- The stock moves. It travels with people and vehicles, so there is no fixed location to track.
- Capture is manual. Usage is logged on paper, late, or not at all.
- No signal. Hospital basements and remote sites break any tool that needs a live connection.
We size the cost of this in your ERP doesn't know what's outside the warehouse.
What real-time visibility is worth
The upside is not abstract. Organisations that implement real-time supply chain visibility can cut stockouts by up to 50% through early inventory alerts and demand sensing. That is fewer failed first visits, less excess capital tied up in stock nobody trusts, and far less shrinkage that no one can trace.
It is no surprise that 91% of decision-makers plan to invest in visibility technology by 2028. The question is where to start, and the answer is the stock the ERP cannot see.
How to get real-time visibility in the field
Closing the gap means capturing what happens to stock outside the warehouse and feeding it back to the system of record in real time. A field inventory layer does it:
- A live digital manifest for every field location: what should be there, by SKU, lot and expiry.
- Point-of-use capture. A scan records each movement in seconds, at the moment it happens.
- Offline-first mobile. Field teams scan with no signal, and the data syncs when the connection returns.
- Real-time dashboards across every location, so leaders see one accurate picture.
- ERP sync. Every event flows back to SAP, Oracle, Dynamics or Sage as the system of record.
The ERP stays the source of truth. The field layer just makes the field visible. See how Ventory handles field inventory management.
The proof
Ventory delivers real-time visibility across 450+ field locations for enterprise customers in MedTech, 3PL, logistics and consumer goods. A national ambulance service holds 99.76% rolling stock accuracy across a fleet of 100 vehicles, with field adoption above 95%, because every movement is captured at the point of use. Deployment runs 4-8 weeks.
Getting started
- Map where your inventory actually sits, including every field location the ERP cannot see.
- Quantify the cost of the blind spot: stockouts, excess stock, shrinkage, unbilled consumption.
- Pilot a field inventory layer at 3-5 of the worst-visibility sites. Target 4-8 weeks.
- Measure stock accuracy and stockout rate against the baseline.
- Scale across the network, feeding the ERP one source of truth.

Frequently asked questions
What is inventory visibility?
Inventory visibility is the ability to see what stock you hold, where it is, and in what state, across your whole network in real time. Real-time visibility means the data updates as movements happen, rather than at a periodic count, so decisions are made on current information.
Why do so few companies have full visibility?
Only 6% report full end-to-end visibility because a large share of inventory sits outside the warehouse, where the ERP cannot see it in real time. Stock in vans, on consignment and at customer sites is consumed without a live signal, so the central picture is always incomplete.
What does real-time inventory visibility deliver?
Organisations implementing real-time visibility can cut stockouts by up to 50%, reduce excess stock, and shrink the shrinkage they cannot otherwise trace. In production, field deployments hold stock accuracy above 99% across distributed locations.
How do you get visibility of field inventory specifically?
A field inventory layer captures every movement at the point of use on an offline-first mobile app, maintains a live manifest per location, and syncs back to the ERP. It gives leaders a real-time view of the stock the ERP and WMS were never built to see.
