The pipeline
How it works, end to end.
Every step is built, benchmarked, and wired into your stack. Here is exactly what happens.
Track inventory
Inventory levels per variant are read continuously from Shopify across all locations.
Compute velocity
The system calculates recent sales velocity and days-of-cover per SKU rather than using a flat threshold.
Factor lead time
Supplier lead times are applied so alerts fire early enough to actually reorder in time.
Trigger alerts
When projected stock dips below the reorder point, alerts go to Slack, email, or a reorder sheet.
Suggest reorder qty
A recommended reorder quantity is included based on velocity and target days-of-cover.
Track resolution
Alerts close out when stock is replenished, and recurring offenders are surfaced for planning.

Before & after
What changes once it ships.
You learn about a stockout from an angry customer
You get a heads-up with enough runway to reorder in time
A flat threshold misfires across fast and slow SKUs
Velocity-aware thresholds flag each SKU at the right moment
Reorder quantities are guessed under pressure
Each alert suggests a quantity from velocity and days-of-cover
Why it matters
The business case
A stockout on a bestseller is doubly expensive: you lose the sales you would have made and you often pay for rushed, premium reordering to recover. Flat "alert at 10 units" rules misfire for both fast and slow movers, so teams either get blindsided or drown in false alarms. Velocity-and-lead-time-aware alerts cut stockout incidents 30–50% by flagging each SKU at exactly the moment there is still runway to reorder.
FAQ
Low Stock Alert System: your questions, answered.
How does a low stock alert system work?+
It continuously monitors your Shopify inventory and warns you before items run out, using sales velocity and supplier lead time rather than a flat number. That means you get the alert with enough runway to actually reorder, not after you have already lost sales.
Why is velocity-based alerting better than a fixed threshold?+
A fixed "alert at 10 units" rule is wrong for both your bestsellers and your slow movers. By factoring in how fast each SKU sells and how long restocking takes, the system flags items at the right moment for each product individually.
Does it work across multiple locations and variants?+
Yes. It tracks inventory per variant across all your Shopify locations and warehouses, so you catch a stockout in one region even if total stock looks healthy. Bundles and components can be monitored too.
Can it recommend how much to reorder?+
Yes. Each alert includes a suggested reorder quantity based on recent velocity and your target days-of-cover, which speeds up purchasing decisions and reduces both stockouts and overstock.
Where do the alerts go?+
To Slack, email, or a live reorder sheet, wherever your ops team works. Recurring stockout offenders are also surfaced so you can fix the root cause in planning.
