Fishbowl counts your inventory daily; GM's JIT line counts it by the minute
Custom inventory management software in Oshawa costs $55k to $140k over 3 to 6 months. Fishbowl, Cin7, and spreadsheets track inventory in periodic counts. A supplier feeding GM Oshawa's just-in-time line needs inventory that updates as parts are consumed in sequence, with min/max tied to the line's takt, not a daily reconciliation that's already stale by morning.
You hold inventory for a sequenced GM program, and Fishbowl or a spreadsheet tells you what you had at the last count. The line doesn't run on counts; it pulls parts in sequence, and your real stock position changes minute by minute. By the time the system catches up, you've either over-ordered raw material tying up cash, or run short on a fast-mover and triggered an expedite to keep the line fed. In a JIT relationship, both mistakes are expensive and both show up on your supplier scorecard.
Off-the-shelf inventory tools assume a warehouse that's counted, not a line that's consumed. Cin7 is fine for e-commerce fulfillment; it has no concept of the takt-paced consumption and sequenced replenishment that govern an auto supplier's stockroom. The gap between periodic inventory and real-time line consumption is where Oshawa suppliers bleed cash and scorecard points.
The case for owning your inventory management
Custom inventory software is fed by line consumption, not a clock. Scans and PLC signals decrement stock in real time, min/max levels are calculated from actual takt-paced demand, and replenishment triggers before you run short. You stop choosing between tied-up cash and expedite freight, because the system sees the line as it happens instead of as it was at the last count.

Delivery, week by week
Exactly what you get
Inventory that tracks the line, not the clock. Stock decrements as parts are consumed, min/max comes from real takt-paced demand, and replenishment fires before a shortage can take the line down. You stop trading tied-up cash against expedite freight. It pairs tightly with a warehouse management system, an ERP, and supply chain software, and feeds business intelligence dashboards for turns and stockout risk.
How to choose a developer in Oshawa
The differentiator is whether they understand JIT and takt. A developer who only knows e-commerce inventory will build you a faster Cin7, not a line-aware system. Ask how they'd calculate a reorder point from line consumption and how they handle a missed scan. Floor integration experience, PLC signals, scanner reliability, separates a real auto-supplier build from a generic inventory app dressed up.
- Real-time inventory driven by line consumption, not periodic counts
- Min/max levels calculated from actual takt and demand, freeing tied-up cash
- Replenishment triggers that prevent line-down expedites before they happen
- One system tying stockroom inventory to live shop-floor consumption
- Scorecard-friendly accuracy that protects your standing with GM
- Real-time accuracy depends on disciplined scanning and reliable floor signals
- Tighter coupling to the floor means a scanner or PLC issue shows up as inventory error
- Custom levels and forecasting need tuning; the model is only as good as its inputs
- Off-the-shelf reporting must be rebuilt to your KPIs
- !They model inventory as periodic counts. Ask how they'll decrement stock from live line consumption.
- !They set min/max as static numbers. Ask how takt drives replenishment in their design.
- !No PLC or scanner integration. Ask how floor consumption reaches the inventory system.
- !No ERP/WMS integration plan. Ask how inventory stays consistent across systems.
- !They promise accuracy without scanning discipline. Ask what happens when a scan is missed.
Most Oshawa teams pricing inventory management end up comparing notes on accounting, project management, lms too; the systems share one data spine.

Frequently asked questions
Can't Cin7 or Fishbowl do real-time?
They update when you scan or sync, but they're designed around periodic counting and warehouse fulfillment, not takt-paced line consumption with sequenced replenishment. For an Oshawa JIT supplier, the gap is conceptual, not just a speed setting; the off-the-shelf tools don't model the line's consumption as the driver of inventory, which is the whole point.
How does the system know what the line consumed?
Through scans at the point of use and PLC signals from the line, decrementing stock in real time. The accuracy depends on disciplined scanning and reliable floor signals, which is why a developer with shop-floor integration experience matters; the model is only as good as the consumption data feeding it.
Will this free up working capital?
Usually yes. The most common win is replacing gut-set min/max with takt-based levels, which cuts the safety stock you carry to compensate for not knowing your real position. Suppliers often find they were over-ordering raw material to avoid line-down risk; real-time visibility lets you carry less without raising that risk.
