In most businesses WhatsApp conversations are scattered across agents' personal phones. The team cannot see them, the CRM does not know about them, and the history leaves with the phone. FlexInbox brings this chain into one flow.
No complex application, template approval or per-number monthly API fee.
FlexInbox lets you connect your agent's existing WhatsApp number, just like WhatsApp Web, by scanning a QR code from the phone. This way you completely skip the WhatsApp Business API application process, template approvals and high message fees. You do not need a new number, you keep going with the number your customers already recognise.
Every message to the connected number appears in the panel instantly, and outbound messages sync one-to-one with your phone. Here is the key point: your customer sees no difference, everything that reaches them is the normal WhatsApp experience, only on your side it is now linked to your CRM and open to your whole team.
To connect a number, the agent simply opens "Linked Devices" in the WhatsApp settings on their phone and scans the QR code in the panel. If the connection drops, FlexInbox restores the session automatically so the conversation continues without interruption.
All of it in one panel, without switching screens or leaving your CRM.
Send and receive images, videos, PDFs, documents, location and voice notes, just like normal WhatsApp.
Reply by quoting a message, add emoji reactions, and see delivered and read ticks.
Several agents use one number, and every outbound message shows who wrote it.
Save frequent replies, send them in one click, and give your team consistent wording.
Tag conversations, open or close them, assign to the right agent and track with the unread badge.
When a message arrives from an unknown number, a record is created automatically in Zoho, Bitrix24 or HubSpot.
