OmiStack - Omnichannel CRM

OmiStack — the complete omnichannel sales solution. It brings every customer conversation into a single place. Sales reps and support agents reply to messages, take hotline calls, look up customer records and work tickets straight from their phone — no desk required.

UNIFIED INBOX
Messages from Zalo OA, Facebook Messenger, Instagram DM, WhatsApp, Telegram, TikTok, website Live Chat, Email and SMS land in one conversation list. Filter by channel, by status, or by the conversations assigned to you. Send text, images and file attachments, and see a customer's full history across every channel in one thread view.

MOBILE SOFTPHONE
Make and receive business hotline calls inside the app over VoIP. Incoming calls ring full-screen like a real phone call, even when the app is closed. Includes a dialpad, call history, and caller details shown the moment the phone rings.

360° CUSTOMER PROFILES
A shared, company-wide contact directory. Each contact shows profile details, conversation history, call history and related tickets — enough context to resolve the issue on the first reply.

TICKETS & TASKS
Create and track support tickets, update their status, and leave internal notes on a timeline. "My Tasks" gathers everything waiting on you, with quick filters.

REAL-TIME NOTIFICATIONS
New messages, conversation assignments and incoming calls are pushed instantly. While the app is open, messages stream in live over a socket connection.
