Do you need Back in Stock on Waise?
No. On Waise a shopper leaves an email or phone number on a sold-out product and gets one alert when it returns, oldest request first, matched to the units restocked. You can sell on pre-order too. The popular app Amp Back in Stock starts at $19 a month. SMS needs your own Twilio.

What it saves in a year
| Store size | alerts a month | Back in Stock plan | A month | A year |
|---|---|---|---|---|
| Small store | 100 | Starter | $19 | $228 |
| Growing store | 500 | Starter | $19 | $228 |
| Established store | 2,000 | Growth | $49 | $588 |
The alert counts are our assumption. Amp’s prices are for regular stores; Shopify Plus prices are higher. The saving is the app’s price times 12. Waise’s own subscription isn’t subtracted here: Waise’s prices.
How to move your data
Waiting lists don’t move. If you have an active one, send a last note before switching, or keep the app until the stock returns.
Who this suits, and who it doesn’t
A good fit
- Your products sell out and come back
- You want alerts sent according to real stock
Pick something else
- You need a direct Klaviyo connection
Questions
Who gets the alert first?
The oldest request first, and only as many as the restocked units can serve, so people who can’t buy aren’t emailed.
Can I take pre-orders too?
Yes. Set it in the product editor, with a ship date and a quantity limit.
The online store that runs itself, with brakes
- AI that acts, with brakes. Pulse changes orders, prices, discounts and content from one conversation. A sensitive change first shows a before-and-after card and waits for your approval, and almost any change can be undone.
- Your money is protected on the server, not by a promise. Anything touching money needs a confirmation tied to the exact values you saw, and the margin guard blocks a price below your minimum, even when an outside AI asks for it.
- Profit, not just sales. An order counts only once your payment provider confirms the money, and profit is worked out after fees, shipping, cost of goods and refunds.
- Open to your own AI. Claude, ChatGPT or Gemini connect to your store over MCP and pass through exactly the same brakes.
- Five ways to build, one system behind them. A ready theme, designing by chat with Pulse, your own code, outside builders like Lovable or Webflow, or your own AI. Checkout, orders, customers and money stay in one place.
- 0% of your sales. One flat monthly plan. When your store grows, our cut doesn’t, because there isn’t one.
- Built by someone who sold. Or Avrahami, a practical electronics and computer engineer, ran an online store on Shopify and built what that store needed. That became Waise.
