Recover lost sales in your ecommerce with AI on WhatsApp

Yes, and that is what separates it from an FAQ bot. I built a sales agent for a pizzeria that assembles the order inside the conversation — product, variants, extras — and finishes with an integrated payment checkout, using Stripe and Redsys as gateways. The customer never leaves WhatsApp to buy. The same pattern applies to an online store: the bot resolves the doubt that was blocking the purchase and takes payment in the same thread, which is precisely where sales are lost today.

It connects to the store's real catalog, not to a list copied by hand. If your store exposes an API, the bot checks price and availability in the moment; if it does not, an ETL is built to sync the catalog automatically. That is the same mechanism I have used to keep catalogs with complex variants in sync — colors, fabrics, and price lists — and to migrate entire catalogs from one platform to another. The point is that nobody should have to update the bot by hand when a price changes.

There are two paths and the choice deserves thought. The official API is the formal route, with approved templates and a per-conversation cost. The alternative is a self-hosted integration, which I run in Docker on a dedicated VPS: more control and a lower cost per message, in exchange for owning the infrastructure. I use both depending on the case. I will walk you through the tradeoff with your real message volume on the table before you decide, because switching paths later is expensive.

The handoff is where sales go cold, so it is solved with a shared inbox: the conversation moves to your team with the full history visible, without asking the customer to repeat anything, and anyone on the team can continue it from the same screen. That is the architecture I built for an operation with several people answering the same number. A bot without an inbox behind it does not save work — it hides it until the customer gives up.

Yes, and it works differently from a recovery email. When the store signals that a cart was left unfinished, the bot reopens the conversation on WhatsApp asking about that specific cart, answers whatever objection comes up — stock, shipping, payment methods — and can close the purchase right there. The advantage over email is that the customer can reply and get an answer immediately. The critical piece is frequency limits: pushing too hard on WhatsApp costs you a block.
