How to Send Inventory and Restock Alerts via WhatsApp
Set up automated WhatsApp alerts for back-in-stock products. Build customer waitlists and send instant restock notifications to capture waiting buyers.
Set up a customer waitlist system for out-of-stock products
Configure Replyot to capture waitlist interest when a product is marked as out of stock. When customers ask about unavailable items, the AI offers to notify them when it returns and records their number.
Create a back-in-stock WhatsApp notification template
Write a restock notification template: '[Product name] is back in stock! Order now before it sells out again: [link/reply YES]. Limited quantities available.' Submit for Meta template approval.
Set up a stock monitoring trigger
Configure a webhook or manual trigger in Replyot that fires when you mark a product as back in stock in your catalog. This trigger activates the waitlist broadcast automatically.
Limit notification batch size for limited stock
For items with limited restock quantities, configure the notification to only go out to the first N waitlist members (matching your restocked quantity), preventing overselling to more customers than you can fulfill.
Set a response window and second-chance notification
If a waitlist notification recipient doesn't order within 24 hours, their slot can be offered to the next waitlist member. Set up a 'second chance' notification flow for items where stock allows.
Frequently Asked Questions
- How do I build a WhatsApp waitlist for an out-of-stock product?
- When Replyot's AI encounters an out-of-stock inquiry, it informs the customer and asks 'Would you like me to notify you when it's back? Just reply YES.' Responses are automatically added to the product's waitlist.
- Can I send restock alerts to customers who didn't explicitly join a waitlist?
- You can include restock alerts in broadcast campaigns to customers who previously purchased the category. However, waitlist members (explicit opt-in) convert at significantly higher rates.
- What if more customers are on the waitlist than the restocked quantity?
- Configure Replyot to notify a batch matching your restocked quantity. Remaining waitlist members are held for the next restock cycle rather than over-notifying and disappointing customers.
