Your business, open inside WhatsApp.
Your customers are already on WhatsApp. With MerxumOS they can find what you sell, choose it, order it and pay for it right there, while your orders and stock update on their own. No app to download, and nobody on your team typing the same answers all day. Appointment and room booking are next, on the same number.

One number, for everything your customers come to you for
Shop
Customers find your products, choose options, order and pay in the chat, at your real prices and against your real stock.
Sound familiar?
Orders get lost in the scroll: an address here, a size there, a voice note nobody has played.
Every "how much?" and "do you have it?" waits for someone to check and type, and the customer who waits buys elsewhere.
A payment screenshot arrives, and someone has to find the order, check the money and write back.
Everything a good salesperson does, inside the chat
Finds what they ask for
Customers type what they want or browse by category, and see product photos and prices drawn live from your system.
Sizes, colours and extras
They choose the size, colour or add-on in the chat, the price follows their choice, and one order can hold several items.
Delivery or pickup, your way
Your delivery fee, your branches and, when you offer them, a day and time they choose, or their own rider to collect.
Payment in the conversation
A secure Pay now button, for card or mobile money. When the money lands, the order confirms itself and the customer is told.
A real receipt, then every update
Order number, items, fee, total and address in the chat, followed by every step from confirmed to delivered.
Follows up on unpaid orders
A reminder after two hours. An order still unpaid after a day closes itself, and its stock goes back on the shelf.
Answers from your settings
Questions about hours, location, delivery and payment are answered from what you saved. When it isn't sure, it says so and offers your team.
Your team steps in anytime
Customers can ask for a person, and your team replies from one inbox. While they do, the automatic replies stay out of the way.
Order again in one tap
Returning customers can refill their cart from their last order, at today's prices and with today's stock.
Every conversation can end in a paid order.
Chat orders run on the same products, prices and stock as your shop and branches. Nothing is typed twice, nobody pays yesterday's price, and the chat won't sell what has run out.
Paid in the chat
A secure button, and the order confirms itself when the money lands.
One stock everywhere
A chat sale and a counter sale draw on the same count.
A person when it counts
Customers can ask for your team at any time, and the chat stands aside.
