Strengths and trade-offs

What it does well
  • 4.5 across 47 reviews, and the only restock app on the marketplace with that much feedback
  • Alerts fire per variant rather than per product — the difference between a useful email and an annoying one
Trade-offs
  • $18/month once the trial ends, with no free tier
  • Email only; there is no SMS or push channel like the Shopify equivalents offer

What "From $18/month" actually means

No free tier on the listing: the entry plan is $18 per month. Most listings at this price offer a trial, but the length is set by the vendor rather than the marketplace — check it before you install, and use it to measure an effect rather than to tour the interface.

Whatever the label says, the calculation is the same: a back-in-stock & pre-order app has to lift revenue by more than it costs. Our break-even calculator works out the lift you would need against your own orders and margin — for most stores it is a fraction of a percent, which means the subscription is rarely the real question. The payload the app adds to every page load usually is.

Is InStockNotify free?

How well rated is InStockNotify?

What are the best alternatives to InStockNotify?
No second back-in-stock & pre-order app on the BigCommerce App Marketplace has enough reviews behind it to recommend as an alternative. If InStockNotify does not fit, the realistic options are a theme customisation or the same job handled by a broader BigCommerce app you already run.
How we assess apps. Ratings, counts, pricing labels and — where the marketplace publishes one — the vendor name come from the public BigCommerce App Marketplace listing and carry the date they were checked. The verdict, the "best for" line and the trade-offs are our editorial judgement. We take no money from any vendor listed here — full methodology.
