Notify customers the moment an out-of-stock item is back — on WhatsApp

WhatsPortal sends personalised restock alerts to customers on WhatsApp the moment their waitlisted product is available — so they buy immediately, your restocked inventory clears fast, and no sale is lost to a 'come back later.'

A customer wants a product. It's out of stock. You take their number. You forget to call when it arrives.

01

Out-of-stock situations happen constantly in retail. The standard response — 'leave your number, we'll call you' — rarely results in a follow-up call. The customer moves on. You restock and wait for them to return, which they often don't.

02

Popular items in specific sizes, colours, or variants sell out and restock regularly. Without a system, every restock is a missed opportunity — the customers who wanted it don't know it's back and may have already bought elsewhere.

03

Manual follow-up on out-of-stock waitlists requires staff to maintain lists, track stock arrivals, and make individual calls. This doesn't scale — especially for a business with 50+ items that may go in and out of stock.

The solution

WhatsPortal maintains waitlists and sends restock alerts to customers on WhatsApp — automatically when items are back in stock.

WhatsApp waitlist registration

When a customer asks about an out-of-stock item, the bot registers their interest — 'We'll notify you on WhatsApp the moment this is available.' Captured, documented, and ready.

Instant restock notification

When the item is restocked — via your POS update, a manual trigger, or webhook — WhatsPortal sends an immediate WhatsApp alert to every waitlisted customer — 'Your [product] in [size/colour] is back in stock. Order now before it sells out again.'

How it works

Streamlined automation in four simple steps.

  1. 01

    Capture waitlist interest on WhatsApp

    When a customer asks about an out-of-stock item, the bot registers them automatically. No manual note-taking required.

  2. 02

    Restock triggers the alert

    When you update stock — manually or via your POS — WhatsPortal sends the restock notification to all waitlisted customers immediately.

  3. 03

    Waitlisted customers buy

    High-intent customers who've been waiting convert immediately. Your restocked inventory sells faster than it would through passive footfall alone.

  4. 04

    Sync store inventory

    Catalog enquiries and appointments are logged in your retail POS and inventory management system.

FAQ

Common questions about retail restock alerts

Can I manage waitlists for multiple products simultaneously?

Yes. WhatsPortal maintains separate waitlists per product, size, and variant. Each restock alert goes only to customers who waitlisted that specific item.

Can I send restock alerts for seasonal or limited-edition items?

Yes. For seasonal launches or limited editions, set up pre-launch interest capture — &apos;Notify me when this arrives&apos; — and broadcast the availability alert to the entire interest list the moment it&apos;s in stock.

Can I set a limit on how many customers receive the alert to avoid over-promising?

Yes. Set a maximum alert count equal to your available stock. Once the limit is reached, remaining waitlisted customers receive a &apos;you&apos;re on the next waitlist&apos; message.

What does WhatsPortal cost?

Free plan: ₹0, 100 messages/month. Standard: ₹1,199/month (5,000 messages). Premium: ₹2,499/month (unlimited). All in INR via Razorpay.
