Stellantis releases parts on a four-hour JIT window; your Windsor supply chain software syncs once a night
Custom supply chain software for a Windsor auto supplier or logistics firm runs $60,000 to $160,000 and 4 to 7 months. Generic SCM and SAP modules assume planned, batched replenishment. Your reality is just-in-time releases from Detroit OEMs on tight windows, trucks timed to a border crossing, and EDI schedules that change inside the day, which a once-nightly sync can't keep up with.
Your customer is a Detroit OEM running JIT, and they release parts on windows measured in hours, not days. The supply chain module in your SAP setup batches and syncs overnight, so by the time it reflects a release, the truck should already be loaded and timed to clear the Ambassador Bridge before the plant's line-side stock runs out. A planning cycle built for weekly replenishment is structurally wrong for a four-hour window.
The border makes it sharper. A load that misses its crossing window doesn't just arrive late, it can shut a line in Michigan and trigger chargebacks that dwarf the freight. Generic SCM has no model for border timing, EDI 862 release schedules that shift intraday, or the real lead time across a specific bridge. For a Windsor supplier, supply chain software that can't think in hours and crossings isn't fit for the job.
The fix: supply chain built for Windsor, not rented
Custom supply chain software thinks in hours and crossings. It ingests EDI releases in near real time, plans loads against actual border-crossing windows and lead times, and warns before a shipment will miss its slot at a Detroit plant. For a Windsor JIT supplier, that early warning is the whole point, the difference between a re-timed truck and a five-figure chargeback for stopping a line.

How long it takes, phase by phase
Exactly what you get
A supply chain system that operates on JIT time: it ingests EDI releases as they arrive, plans loads against real border-crossing windows, and warns you before a Detroit slot will be missed, while you can still re-time the truck. The payoff is fewer five-figure chargebacks and a clean release-to-dock timeline. It connects to your ERP (Enterprise Resource Planning), warehouse management system and a warehouse-floor mobile app, and feeds business intelligence dashboards on OEM scorecards.
How to choose a developer in Windsor
Hire a team that has integrated OEM EDI and understands border timing as a first-class constraint, not a footnote. Ask exactly how their system reacts when an 862 release shifts at 10am and the load must clear by 2pm. Real-time integration is hard and depends on reliable feeds, so confirm their plan for EDI and carrier data. A JIT auto-supplier reference is non-negotiable here; weekly-replenishment experience won't transfer.
- Near-real-time EDI release ingestion instead of an overnight batch
- Load planning against actual border-crossing windows and lead times
- Early warnings before a shipment misses its Detroit delivery slot
- Visibility from release to crossing to dock in one timeline
- Fewer chargebacks because the system flags risk while you can still act
- A real-time supply chain build is expensive and integration-heavy
- It depends on reliable EDI and carrier data feeds you must secure
- Overkill if you ship on planned weekly cycles, not JIT windows
- OEM EDI onboarding and testing add time and coordination
- !Their SCM syncs nightly; ask how it reacts to an intraday EDI 862 change
- !No border-timing model; ask how crossing windows factor into planning
- !No missed-window alerting; ask how risk surfaces before a truck is late
- !No EDI onboarding experience; ask how they've integrated OEM feeds
- !No JIT auto-supplier reference; ask for one

Frequently asked questions
Why can't standard SCM handle JIT supply to Detroit?
Standard SCM and SAP modules plan on batched, often nightly cycles built for weekly replenishment. JIT releases from a Detroit OEM arrive on hour-long windows, so a nightly sync is structurally too slow. Custom software ingests releases in near real time and plans against border windows.
How does border timing factor into the software?
It models the actual crossing windows and lead times for the Ambassador and Gordie Howe bridges, so load planning accounts for clearance time and the system can warn when a truck will miss its Detroit slot.
What does missed-window alerting actually save?
A missed JIT window can stop a line in Michigan and trigger chargebacks that far exceed the freight cost. Early alerts let you re-time or expedite while it still matters, which is where the system pays for itself.
