The shared inbox for WhatsApp-first businesses
Every customer conversation in one place
Kaltline is the shared inbox for businesses that sell and support on WhatsApp. Messages, calls, quotes and order confirmations arrive in one place, so your team can answer faster and nothing falls through.
Works across
- Calls
- SMS
- Customer portal
How it works
From first message to confirmed order
Kaltline keeps the whole exchange in one conversation: the chat, the call, the quote and the order.
01 WhatsApp
One queue for every chat
Customer messages arrive in a shared inbox the whole team works from. Assign a conversation, reply as the business and see at a glance who is waiting for an answer.
- Assigned, unassigned and awaiting-reply views
- Internal notes your customer never sees
02 Calls
Calls and callbacks beside the chat
Calls and callback requests sit in the same conversation, so whoever picks it up next can see what was said and what was promised.
- Calls shown on the conversation they belong to
- Callback requests with a follow-up time
03 Quotes and orders
Quote in the conversation, confirm with one link
Send a quote from the conversation. The customer reviews it and confirms on a link, and the order is recorded once, against current prices and stock.
- Opening or previewing a link never places an order
- A second tap on Confirm does not create a second order
04 Customer portal
A portal for your customers
Customers sign in to see their own conversations, quotes and orders, send a message and confirm a quote. They never see your internal notes.
- Separate customer accounts and sessions
- Scoped to the signed-in customer
05 Flows
Flows that route and follow up for you
Route new conversations to the right team, chase quotes that have gone quiet and hand work over with flows. Simulate a flow before you publish it, and keep every published version.
- Branches, approvals and callbacks
- Version history with a read-only preview
Under your own name
Your customers see your business, not ours
Upload your logo and choose your colour. Your team signs in at your own workspace address, and your portal and order confirmation pages carry your name. Kaltline appears only as a small “Powered by” line.
- Your logo, initials and brand colour across the workspace
- A sign-in page at your own workspace address
- Branded confirmation links for your customers
