Custom WhatsApp Support Bot with AI Upsell
A support channel drowning in 100+ requests a day, replaced by a bot that handles the work itself — and upsells while it’s at it.

The challenge
The client was receiving over 100 WhatsApp requests a day from customers needing help with purchases made on their website. The volume was unsustainable, the questions were largely repetitive, and off-the-shelf WhatsApp bot services meant handing ownership of a core customer channel to a third party — along with the ongoing fees that come with it.
The result
A custom WhatsApp bot connected directly to the Meta WhatsApp Business API, tailored to the client's actual support patterns. Request volume dropped from 100+ per day to under 10 per week, the client retained full ownership of the channel, and the bot now drives additional revenue through AI-powered product recommendations.
100+ daily requests → under 10 per week
The client had a volume problem dressed up as a support problem.
Over 100 WhatsApp requests were landing every day, nearly all of them from customers needing help with purchases made on the website. The questions were repetitive — order status, delivery timing, product details — but each one still had to be answered by a human. The team was spending most of its day replying to messages that a system could have handled, if the system existed.
The obvious route would have been a third-party WhatsApp bot service. The client didn’t want that. Handing a core customer channel to an external platform meant paying ongoing fees, depending on someone else’s uptime, and losing the ability to shape the experience around their specific business. They wanted to own it.
So the bot was built from the ground up, connected directly to the Meta WhatsApp Business API. It was trained on the questions the client actually received, not a generic support template, and it plugs into the website and other internal services to answer customer queries on its own — pulling real order data, checking real stock, giving real answers without a human in the loop.
The AI layer is where it stops being a cost centre and starts being a revenue channel. A customer can share an order number and the bot, connected to AI, makes recommendations for complementary products based on what they actually bought. Support interactions now end with a relevant upsell instead of a closed ticket.
Daily request volume dropped from over 100 to under 10 per week. The client owns the infrastructure outright, pays no per-message fees to a middleware provider, and has a support channel that pays for itself through the recommendations it generates.
The conventional answer was to buy a bot. The right answer was to build one.
