what is WhatsApp commerce?

WhatsApp commerce is a subset of conversational commerce — but it earns its own name because WhatsApp behaves differently from other channels. It's the default messaging app for hundreds of millions of people, especially across Latin America, so writing to a business there costs the customer no new app, no login, no learning curve. For many buyers it's more natural to ask a brand "do you have this in my size?" on WhatsApp than to navigate a full web catalog and an unfamiliar checkout.

WhatsApp also has structure that makes commerce workable at scale: a business can run on the official WhatsApp Business Platform (Cloud API), with a 24-hour service window for free replies and approved HSM templates to reach back out afterward for reminders and notifications. That's what separates real WhatsApp commerce from a single overwhelmed phone answering by hand.

Done well, it spans the whole journey inside the thread:

• Discovery and inquiry: the customer arrives from an ad or link-in-bio and asks about price, stock, sizes or shipping — and expects an answer now, not in hours.
• Recommendation: the business suggests products based on real catalog and stock, not a static list.
• Checkout: the order is confirmed and a payment link or checkout is delivered in the chat, without sending the customer to rebuild a cart elsewhere.
• Cart recovery: when a checkout is abandoned, the business reaches back out on WhatsApp — the channel the customer already used — rather than a generic marketing email.
• Post-sale: shipping updates, returns and repeat orders happen in the same thread, with the history intact.

The catch with WhatsApp is exactly what makes it powerful: customers expect immediacy, and there are a lot of them. A human team can't hold hundreds of simultaneous threads, outside office hours, without response times slipping — and on WhatsApp, a slow reply is a cooling sale. An AI agent answers instantly, checks real orders and stock, moves the customer forward, and escalates to a person only when it should. That's how a store keeps the immediacy WhatsApp rewards without hiring a night shift.

heysteff publishes an average 4.2x lift in abandoned-cart recovery when the agent reaches out through the customer's own messaging channel instead of a generic email, alongside 87% of conversations resolved without a human and first response under 9 seconds.

There's also a discipline side to WhatsApp commerce that's easy to miss: because it runs on a channel people consider personal, sending matters as much as answering. Outbound messages — campaigns, cart nudges, reminders — have to respect Meta's template rules and, on an unofficial number, be paced so a burst of sends doesn't look like spam and get the number restricted. Real WhatsApp commerce is as much about sending responsibly as it is about replying fast.

heysteff connects to WhatsApp two ways — the official Cloud API and an unofficial number via Baileys — so a store can start with the number it already has or go fully verified. Steff answers in the brand's tone, queries the Shopify catalog and real order status, recovers abandoned carts over WhatsApp, books appointments synced to Google Calendar, and hands off to a human in one click through copilot mode. Because it's multichannel underneath, the same conversation history follows the customer if they later write on Instagram or email.
