A warm Malaysian bubble tea shop counter at golden hour, with a friendly young Southeast Asian barista in a linen apron carefully pouring fresh boba pearls into a clear plastic cup behind a worn wooden counter, three sealed bubble tea cups in a row on the counter, a small handwritten menu chalkboard in the background, and the mint-green admin mascot standing on the counter beside the cups holding a small chat-bubble-and-phone prop as if reading the next order.

Illustrative scenario

This is a written composite, not a real customer. The problem, the configuration and the numbers are the kind we expect to see when minidesk runs in production — they are not measurements from a named business. The first real, on-the-record case study lands the day a customer agrees to be quoted.

The problem

Three outlets, one WhatsApp number, and one person — the owner's daughter — answering every customer message between 11 am and 10 pm. Customisation questions (less sugar, less ice, oat milk, brown sugar, no boba), order changes, pickup times, delivery queries, the rare complaint. The phone buzzed 100–150 times a day. Average reply time was four hours during peak, and the customers who did not get a reply in the first few minutes ordered from the competitor down the road.

What the AI does today

minidesk sits between the StoreHub POS and the WhatsApp inbox. The AI reads the menu, the day's stock levels, the day's running sales, and the order history. It replies to customisation questions, confirms orders against today's stock, gives pickup ETAs from the kitchen screen, and only escalates to a human when the customer asks to speak to a person or when the AI is below its confidence threshold.

What the owner says

“My daughter used to spend seven hours a day on WhatsApp. Now she spends it on the floor of the busiest outlet — which is the job she actually wanted, and the place the customers come to see her.”
