Cart Line puts a real storefront on a business’s own domain — and then lets the customer finish the order inside WhatsApp, the app they already have open. No download, no account, no abandoned cart at the sign-up screen.
Not a marketplace stall and not a link-in-bio page. The business’s own address, its own branding, and traffic that belongs to it rather than to a platform.
The store link opens a WhatsApp-native checkout. The customer never installs anything or creates an account — they order in the chat they already live in.
The moment an order confirms, a branded receipt lands in the customer’s WhatsApp. No one at the shop has to remember to send it.
Minimal boutiques through full restaurant menus. A shop picks one and it is dressed with real content, not a blank grid to fill in later.
The methods Pakistani customers actually use, as the default path rather than an afterthought behind card processing.
The platform does not take a cut of sales. What the shop sells, the shop keeps.
A store that is painful to update is a store that goes stale in a month. Most of the engineering here went into making changes feel immediate.
Change a price or swap a photo and the storefront re-renders before your finger leaves the key. Editing feels like typing, not like publishing.
Work in progress is saved continuously but never shown to customers. The live store changes only when the owner says so.
Existing catalogues import rather than being retyped, which is usually the real reason a shop stays on software it has outgrown.
Businesses with more than one location get a ‘pick your location’ step, with stock and orders scoped per branch.
The editor is its own surface, so building a store does not mean learning the whole business dashboard first.
Menus, modifiers, kitchen tickets and dine-in tables arrive together for food businesses rather than being assembled by hand.
Cart Line is one of five One Line products, and the useful part is what happens when a shop switches on a second one.
An in-person sale and an online sale decrement the same stock, so the website cannot sell what the shop just sold across the counter.
Sales, cost of goods and gross profit land in a real double-entry ledger automatically, instead of being reconstructed at month end.
The AI answering WhatsApp and the storefront taking the order are the same system, working from the same catalogue and the same customer history.
“Every small shop in Pakistan already sells on WhatsApp. They send photos, they take orders in chat, they confirm on a call. The mistake most ecommerce software makes is trying to move them off that and onto a checkout page — which is asking the customer to install a habit they do not have.”
“So Cart Line went the other way. Keep the storefront for browsing, because people do want to see a real catalogue on a real domain. Then hand the order back to WhatsApp, where both sides already know what they are doing.”
“The 14ms editing is not a vanity metric either. Shops that find editing slow stop editing, and a storefront that has not changed in three months stops selling. Making it feel instant is what keeps it alive.”
