WhatsApp follows the customer from the first interest to post-sale, and not only at the moment of purchase. Studies show that consumers use the channel throughout the journey. See how to structure it.

Discovery and doubt

The journey starts when the customer asks: price, availability, how it works. Since they expect a quick response and prefer to resolve via message, this first contact needs to be answered immediately. Delaying here means losing before even starting.

Consideration and decision

Next, the customer compares and decides. It is the moment to qualify (understand what they need) and guide clearly toward the purchase. A fast and useful service in this phase builds trust and speeds up closing, while vague answers push the customer to the competitor.

Purchase and post-sale

Closing does not end the journey. Order status, usage questions, exchanges and support continue on WhatsApp, and a good post-sale generates repeat purchases and referrals. Neglecting this stage loses the customer who has already been won, the most expensive to lose.

AI throughout the journey

An AI agent covers the repetitive edges of each stage: it answers the initial doubt instantly, qualifies, and handles basic post-sale, escalating to a human at decisive moments. With a unified inbox, the team monitors everything and takes over when it matters.
