Restock & Waitlist Alerts
The moment stock comes back, everyone who asked for it gets told first.
What it watches
Stock levels crossing from zero to positive
What it does
Notifies everyone on the waitlist for that item by email/SMS the moment it is back
When it asks a human first
This is a pure notification agent — never (it does not make pricing or inventory-allocation decisions; anything beyond notifying the waitlist goes to you). The one exception is a delivery complaint: a customer who insists they never got their alert despite being on the list is still routed to you as a support case to check, since that’s a service issue, not a pricing or allocation call.
How it works
- 1Watches stock levels
Monitors your storefront’s inventory feed for any item crossing from zero to a positive count — and filters out a same-day inventory correction, so a quick zero-then-back-to-zero blip from a stock recount never fires a false restock alert to the whole waitlist.
- 2Notifies the waitlist
Sends an instant email or SMS to everyone who asked to be notified, ordered by who joined the waitlist first. If the restocked quantity is smaller than the waitlist itself, it notifies only as many people as there’s stock to cover, rather than triggering a second wave of disappointed customers.
- 3Tracks conversion
Follows whether a notified customer actually completes a purchase, so the report shows real recovered demand, not just messages sent. It also times how long stock survives after the notification goes out — a restock that sells through in minutes versus one that lingers for days says something different about real demand.
- 4Flags high-demand items
An item with an unusually large waitlist gets surfaced for you — it may be worth increasing the reorder quantity. The comparison runs against that SKU’s own restock history, not a flat number, so a naturally niche item never gets miscompared against your bestseller.
- 5Never touches pricing
It is a pure notification loop — it does not raise prices on high-demand restocks; that stays your call. It also never reserves a unit for any one waitlisted customer — stock still sells strictly first-come, first-served through your storefront’s own checkout, exactly as if no notification had been sent.
What triggers it
- · Stock crosses from zero to a positive quantity
- · A customer joins the waitlist for an out-of-stock item
- · A restocked item drops back to zero within 24 hours
- · A waitlist reaches a size worth a pre-order option
What you get
- · An instant email/SMS to everyone on the item’s waitlist
- · A ranked list of most-waitlisted out-of-stock items
- · A weekly restock-conversion report — notified vs. purchased
- · A pre-order suggestion flagged when a waitlist is large enough
Not the right fit if
Not for made-to-order businesses that never actually run out of stock — there is no restock event for this agent to catch. It’s also the wrong fit for one-of-a-kind or vintage resale, where a sold-out item genuinely never comes back in that exact form — a waitlist notification just sets up an expectation the business can’t fulfil.
The math
At ~30 restock events/mo × 5 min, that is roughly 2.5 h/mo — an estimate, not a guarantee.
Frequently asked
Yes — by waitlist join order by default, or by customer tier if you set one up at signup.
Notifications still go out in order; anyone too late to buy stays on the list for the next restock automatically.
Yes — both are supported alongside email/SMS, useful for FA-market storefronts.
No — Inventory Sync keeps stock accurate across channels; this one is the customer-facing notification layer on top of it.
You mark it discontinued once and the agent notifies the waitlist that it’s not coming back, instead of leaving people waiting indefinitely for a restock that will never happen.
