Across the two biggest categories we audit,41 of 55 tools (75%) now ship a native WhatsApp workflow. That's no longer a differentiator tacked onto a pricing page; it's on its way to being table stakes.

One honest caveat about the word "integration"
Our checklist records whether a WhatsApp workflow exists — a verified Yes/No — not how deep it goes. In practice the label spans everything from a share button on an invoice to a full WhatsApp Business API pipeline with templated compliance reminders and two-way document collection. Two tools with the same Yes can deliver very different daily experiences, so once you've shortlisted from the lists above, check the vendor's own documentation for whether it's API-grade automation or a share sheet. The vendor pages linked above carry each tool's sources so you can go straight to the primary material.
The direction, though, is unambiguous: at 75% adoption across55 tools, WhatsApp has become the default client channel Indian CA software is built around — email is now the fallback.
