The three triggers

Enhanced plan

Your shop has one Custom Stock Notification rule. Inside that rule you can switch on any combination of three triggers. Each trigger is evaluated independently every time Shopify reports an inventory change for a variant.

Stock-out alert

Fires the moment a variant’s on-hand inventory crosses to zero. No configuration value — just enable it.

Triggers when inventory drops from a positive number to zero or below.
Will not re-fire while the variant stays at zero — it only re-arms after stock rises above zero again.

Use it for the loudest alerts: “tell me the second something goes out of stock.”

Stock threshold

Fires the moment a variant’s on-hand inventory crosses below a number you configure (for example, 30 units).

Set a threshold value (units).
Triggers when inventory crosses from above the threshold to at or below it.
Will not re-fire while inventory stays below the threshold — it only re-arms once stock rises above the threshold again.

Use it for early warnings on slow-moving SKUs, before they hit zero.

Days from reorder point

Fires when forecast-projected days until reorder drops to or below a number you configure (for example, 7).

Set a days value.
Logistified uses your forecast to estimate when each variant will hit its reorder point. When that estimate is short enough, the trigger fires.
A 48-hour per-variant cooldown prevents the same variant from re-alerting if the forecast wobbles. After 48 hours the trigger can fire again if the estimate is still within your window.
Variants without enough forecast data are silently skipped.

Use it for “what should I order this week?” alerts that catch slow drift before it becomes a stock-out.

Choosing what to monitor

The Triggers tab has a Monitoring Scope card with two choices:

Monitor All Variants — the default-trigger values you set above apply to every variant in your selected Forecast View.
Monitor Only Specific Variants — only the variants you explicitly add (in the per-variant section below the defaults) are monitored. Default triggers are ignored.

Whichever mode you pick, you can add per-variant overrides for any variant — for example, a higher threshold for an A-tier SKU.

Forecast View scope

The rule’s General tab requires you to pick a Forecast View. This view acts as the rule’s scope: the rule only fires for variants that appear in that view.

Pick a view that already represents the variants you care about (e.g., a view filtered to your active catalog).
To narrow to one buyer’s category, save a Forecast View for that category and select it here.
If you delete the view you’ve selected, the rule is deactivated — pick a new view to re-enable it. Alerts do not silently fall back to “all variants.”
