This is Part 4 of our 6-part series on the dangers of SCM Vaporware. Read Part 3: Calculating the True Cost of SCM Vaporware for the financial side, and Part 5: Defending Against SCM Vaporware for what to put in the contract.
Part 3 covered the money. This part covers the freight.
A supply chain runs on data that arrives on time. When the software meant to move that data does not work, goods stop moving in ways you can see on the dock. This post walks through where the damage shows up: visibility, stock, partner links, manual work and the ability to react.
The Vacuum of Data: Navigating Blindly
Supply chain software is sold on one promise. You will know where everything is.
Now consider what happens when it does not work. Most buyers start switching off the old system before the new one is live. Maintenance contracts lapse. The team that knew the old reports moves on. Then the go-live date slips, and slips again, and there is nothing in between.
Managers go back to email, spreadsheets and phone calls to find a shipment. That is slower, but the real cost is reaction time. A port strike or a storm needs a decision the same day. Finding out on Friday what happened on Tuesday is how a small delay becomes a missed season.
The Inventory Bullwhip Effect Amplified
Buying decisions need a demand number. Vendors sell algorithms that promise to end both stockouts and excess stock.
When those algorithms do not work, buying falls back on judgement and a spreadsheet. Some buyers will over-order to be safe. Others will under-order because their manual maths was wrong.
Both directions cost. Over-ordering fills the warehouse, runs up holding cost and spoils anything perishable. Under-ordering empties the shelf and loses the sale. This is the bullwhip effect: each tier adds its own caution, and the swings get larger the further upstream you go.
The Disintegration of the Partner Network
A supply chain is not one company. It is suppliers, factories, forwarders and last-mile carriers, connected by EDI messages and APIs.
When the promised connections do not exist, the messages stop.
- Suppliers do not get purchase orders, so production waits.
- Freight forwarders do not get customs paperwork in time, so containers sit at the port.
- Warehouses do not get advance shipping notices, so the receiving dock works blind.
Each of those lands on a partner who did not choose your software. That is the part that takes longest to repair.
Reverting to the “Swivel Chair” Interface
The most demoralising part is manual re-entry. The industry calls it the swivel chair: two screens, one person, copying between them.
If the software cannot pull from the planning system and push to the warehouse system, someone does it by hand. Analysts hired to improve the operation spend their day retyping shipment data.
It is slow, and it introduces errors that cost more than the typing. One wrong digit in a container number or a customs value can hold a shipment for weeks and trigger a fine. The volume of manual work is what sets the pace of the whole operation.
The Loss of Agility in a Volatile World
Agility means changing sourcing or routing quickly when something goes wrong. It is the thing buyers say they are paying for.
When the software does not work, that ability goes. A tariff change or a closed corridor needs a comparison of alternatives this week. If the data is split across systems and the process is manual, the comparison takes weeks, and by then the choice has been made for you.
Conclusion: The Physical Reality of Phantom Tech
Supply chain software does not only sit on a server. It controls where thousands of tonnes of goods go. When it does not work, that shows up on a dock.
So the rule is about sequence. Verify that the new system does the work before you switch off the one that does. An old system that works beats a new one that only exists in a demo.
Ask for the function in front of you, with your own data, before anything is decommissioned.

Frequently Asked Questions (FAQ)
How does software that does not work cause stockouts?
It leaves buyers without a trustworthy stock or demand number. They either reorder late or order the wrong quantity from a manual estimate. Both end in empty shelves.
What is the “bullwhip effect” and how does bad software worsen it?
Small changes in retail demand turn into larger swings in wholesale, distributor and factory orders. Without shared, accurate data, each tier orders extra to protect itself, and the swings grow.
Why do integrations fail with vaporware?
Integrations need working, documented APIs. If the vendor has not built the back end, the endpoints either do not exist or fail under load. Ask to call them with your own data before signing.
Can manual workarounds replace supply chain software temporarily?
For a small, local operation, briefly. At volume they do not hold: error rates rise and the pace of the operation drops to the speed of typing.
How do you keep goods moving while a system is being replaced?
Keep the system that works running until the new one has been shown to do the job with your own data. Write the test into the contract, and set the decommission date after it passes, not before.
