Quick answer
What is business messaging for Customer Support & BPO?
Customer support messaging moves routine conversations from phone calls to WhatsApp, SMS and IVR: ticket confirmations, status updates, callback requests and CSAT surveys. For BPOs it means running these channels for several client brands, each with its own registration and sender.
Last updated: 21 October 2026
Support teams and BPOs handle high volumes for their own brand or for clients. Moving routine queries to messaging and automating updates reduces call volume and waiting time.

Compliance for Customer Support & BPO
- Register each client brand separately on DLT and with Meta; don't send one brand's messages under another's sender.
- Record and store customer conversations securely, and only as long as needed under the DPDP Act.
- Outside the 24-hour WhatsApp window, use approved templates only.

Customer Support & BPO FAQs
Can several agents use one WhatsApp number?
Yes. The WhatsApp Business API supports a shared inbox with assignment, tags and notes.
Can a BPO send messages for multiple clients?
Yes, but each client brand needs its own DLT registration and, for WhatsApp, its own business account and number.
When is the 24-hour WhatsApp window relevant?
Inside 24 hours of the customer's last message you can reply freely; after that you need an approved template.
Can a chatbot answer first and hand over to an agent?
Yes. A bot can handle common questions and pass the chat to an agent with the full history.
How do BPOs separate client data?
Use separate accounts or sub-accounts per client, with separate senders, templates and reports.
Can IVR send a WhatsApp link?
Yes. A caller can press a key to receive a WhatsApp or SMS link and continue in chat.
Are support messages charged on WhatsApp?
Replies inside the customer service window are billed under Meta's current rules for service conversations; templates outside it are billed per message by category.
Can we measure agent performance?
