WhatsApp back in stock templates
A WhatsApp back in stock message names the exact product and variant the customer wanted, says it is available now, and lets them buy in the same chat. Below are 10 templates to copy, from a simple restock alert to size restocks and preorders. AeroChat sends them when stock changes in your store and can take the order in the same chat.
What a back in stock message should do
The customer already wanted this item. The message only has to remind them which one, confirm it is available, and make buying easy. Name the product, the variant and the price. Say if stock is limited only when it really is.
Send it soon after the restock, and only to customers who asked to be told. A customer who asked about a size last week is the strongest lead you have.
The WhatsApp rules that apply
These are promotional messages, so outside WhatsApp’s 24-hour customer service window they go out as approved marketing templates. Meta’s guidelines put sales offers and prompts to buy in the marketing category. Send them only to customers who agreed to hear from you on WhatsApp, and give them an easy way to stop. See WhatsApp opt-in and opt-out, the WhatsApp message templates guide and WhatsApp message templates.

Meta’s guidelines don’t name back in stock alerts as an example in either category. A message that encourages the customer to buy is at risk of being classed as marketing, so plan for these to be marketing templates. If the customer messaged you in the last 24 hours, you can tell them in a normal reply.
10 WhatsApp back in stock templates to copy
Copy a template, change the wording to match how your store talks, and keep the variables in double curly brackets. AeroChat fills them from your store data when it sends the message.
1. Simple restock alert
Use for a customer who asked to be told when a product came back.
Hi {{customer_name}}, good news. The {{product_name}} you asked about is back in stock at {{store_name}}.
Price: {{price}}
Reply here if you want it and I'll send your payment link.
2. Size or variant restock
Use when the customer was waiting for one size or color.
Hi {{customer_name}}, the {{product_name}} in {{variant_name}} is back in stock.
You asked about this one on {{request_date}}. Would you like me to put one aside and send your payment link?
3. Limited quantity
Use only when the restock really is small.
Hi {{customer_name}}, the {{product_name}} is back, but only {{quantity}} came in this time.
Reply YES and I'll send your payment link now.
4. Restock with delivery date
Use when the delivery promise helps the decision.
Hi {{customer_name}}, the {{product_name}} is back in stock.
Order by {{cutoff_time}} today and it ships {{dispatch_day}}. Delivery to {{customer_area}} is {{delivery_fee}}.
Want me to send your payment link?
5. Back in stock with checkout link
Use when you want the customer to finish on your website.
Hi {{customer_name}}, the {{product_name}} is available again at {{store_name}}.
You can order it here: {{product_url}}
Or reply with any question and I'll answer here.
6. Preorder now open
Use when the next batch is confirmed but not in the warehouse yet.
Hi {{customer_name}}, the {{product_name}} you asked about is open for preorder.
It ships on {{ship_date}}. Price: {{price}}.
Reply if you want to reserve one and I'll send your payment link.
7. Restock of a past purchase
Use for a customer who bought the item before and may want it again.
Hi {{customer_name}}, the {{product_name}} you bought from {{store_name}} in {{last_order_month}} is back in stock.
Reply REORDER and I'll set up the same order for you with a payment link.
8. Bundle back in stock
Use when a set or bundle was missing one item.
Hi {{customer_name}}, the {{bundle_name}} is complete again. Every item in the set is back in stock.
Reply here and I'll send your payment link for {{price}}.
9. Restock with a choice
Use when several variants came back and the customer’s choice is unclear.
Hi {{customer_name}}, the {{product_name}} is back in {{available_variants}}.
Which one would you like? I'll check your size and send the payment link.
10. Last call after a restock
Use once, a few days after the first alert, if the item is selling out again.
Hi {{customer_name}}, a quick note: the {{product_name}} is running low again after this week's restock.
If you still want one, reply here and I'll send your payment link.
Send these automatically with AeroChat
AeroChat keeps a list of customers who asked about an out-of-stock product in chat, with the exact variant. When the stock count in your store platform, such as Shopify, WooCommerce or Wix goes back above zero, it sends the matching template:
- Restock alert and variant restock: product name, variant, price and stock come from your store catalog. The request date comes from the original chat.
- Limited quantity and last call: sent only when the stock count is below the level you set.
- Restock with delivery date: the cutoff and delivery fee come from your shipping rates.
- Reply to buy: when the customer says yes, AeroChat creates the order and sends a payment link, for example through Airwallex. Payment is detected automatically and the order is confirmed in the chat. The customer never has to type “paid”.

Questions
Is a back in stock alert a marketing or utility template?
Meta’s guidelines don’t settle it by name. Utility templates must not contain anything promotional or persuasive, and a restock alert usually invites the customer to buy. Plan for a marketing template and send it only to customers who asked or opted in.
How does AeroChat know who to tell?
When a customer asks about a product that is out of stock, AeroChat offers to tell them when it is back and records the product and variant. It sends the alert when your store shows stock again.
Can the customer buy straight from the alert?
Yes. The customer replies, AeroChat confirms the variant and sends a payment link in the same chat. The order is created once payment is detected.
Should I send a reminder if they don’t reply?
One follow-up is enough, and only if stock is running low again. Sending more invites the customer to block or report your number.
