Sell on WhatsApp and Your Online Store From One Catalog

Most small businesses in Pakistan now sell across more than one channel. You take orders on WhatsApp, you have an online store link you share on Instagram and Facebook, and many of you also ring up sales at a physical counter. The trouble starts when each of those channels keeps its own separate list of products.

• You add a new item to your website, then re-type the same name, price, and photos into your WhatsApp replies.
• You sell three units at the shop, but your website still shows them in stock.
• A price change has to be made in three places — and you forget one.
• A customer asks on WhatsApp whether something is available, and you have to go check manually.

This double and triple data entry wastes time and, worse, leads to overselling — taking an order for stock you have already sold somewhere else. One Line removes that problem by giving you a single catalog that powers all of your selling channels at once.

One Line is one connected platform with three selling surfaces that share the same product data:

• Botline — your WhatsApp AI assistant that can answer product questions and take orders in chat.
• Cart Line — your online store (storefront) that customers browse and check out on.
• POS Line — your retail point-of-sale for selling at a physical counter.

The key idea is simple: you add a product once, and it becomes available everywhere. The product name, description, photos, price, and stock count live in one place. When the WhatsApp assistant quotes a price, when a shopper views your storefront, and when a cashier scans an item at the counter, they are all reading from the same catalog. There is no copying between systems because there is only one system.

Getting started takes only a few steps. You build the catalog once, in Cart Line, and the other channels pick it up automatically.

1. Create your store. Sign up for Cart Line and set up your storefront — your store name, logo, and basic details.
2. Add each product once. For every item, enter the name, description, price, photos, and the quantity you currently have in stock. You can organise items into categories so customers can browse easily.
3. Set your stock counts. Enter the real on-hand quantity for each product. This single number becomes the shared stock count used across every channel.
4. Publish. Once published, your products are live on your Cart Line storefront and available to your Botline WhatsApp assistant. No second entry needed.

If you are moving from another platform such as WooCommerce or a manual list, you can build the catalog in the same way — you only ever enter each product one time.

Because Botline and Cart Line share the same catalog, conversations and browsing flow into each other smoothly.

• A customer messages you on WhatsApp. The Botline AI assistant can answer questions about your products — what you sell, the price, and whether an item is in stock — using the same catalog data your storefront uses.
• You can share your Cart Line storefront link in the chat so the customer can browse the full range and check out on your website.
• A shopper who starts on your storefront can just as easily continue the conversation on WhatsApp, and the assistant already knows the same products.

The customer experiences one consistent business across both surfaces — the same prices, the same products, the same availability — instead of two disconnected channels that contradict each other.

This is the part that protects your reputation. Because all channels read and write to one shared stock count, a sale on any channel reduces the available quantity everywhere.

• Sell an item on your Cart Line storefront, and the stock available to WhatsApp and the counter drops too.
• Sell the last unit at your physical counter through POS Line, and your online store reflects that it is no longer available.

You stop promising customers stock you have already sold somewhere else. When something runs out, it shows as out of stock across the board, so you never have to apologise for an order you cannot fulfil. And when new stock arrives, you update the count once and every channel is current again.

If you only sell online and over WhatsApp, Cart Line plus the Botline assistant may be everything you need. POS Line becomes valuable the moment you also sell in person — a shop, a stall, a counter, or a pop-up.

Adding POS Line lets your staff ring up walk-in sales using the very same catalog and the very same stock count. A counter sale and an online sale draw down the same inventory, so your numbers stay correct no matter where the customer buys. POS Line is built for Pakistani retail, so you can take in-person payments and keep your physical and online selling unified rather than running them as two separate businesses.

You can start with Cart Line and turn on POS Line later — there is nothing to migrate, because the catalog and stock are already there. POS Line, Cart Line, and Botline are all part of One Line and are included in your One Line plan. See pricing for details.
