Choosing between KairosAI and Zoho Bigin?
Bigin is Zoho's pipeline-centric CRM for micro and small teams: cheap, quick to set up and genuinely well-loved. KairosAI is a custom AI workforce that answers your phone and chat itself, in Hindi and English, and also keeps GST books and runs payroll, one platform instead of a stack of Zoho apps.
Every Bigin claim below is grounded in bigin.com (July 2026), including its verified INR pricing (billed yearly, pre-GST).
What each platform actually ships.
| Capability | KairosAI | Zoho Bigin |
|---|---|---|
| Autonomous AI voice agent (PSTN) | Native inbound + outbound calls on Indian numbers, Hindi + English, on Growth+ plans, from a prepaid ₹ wallet. | No. Bigin has built-in telephony (click-to-call and call logging), but no autonomous agent that dials, answers and converses. |
| AI that does the work vs assists | Agents run conversations autonomously across voice, WhatsApp, Instagram, email and web chat. | Bigin AI (Premier+) is an assistive copilot: writing assistant, record summary, reply assistant, with monthly AI credits. It helps a human rep. |
| A first-class AI agent surface with shared memory across channels. | WhatsApp integration from Express+, handled by a person rather than an AI agent auto-resolving conversations. | |
| GST invoicing / Books (accounting) | Native Books with GST invoicing in the same platform. | Payment links only; real GST invoicing / accounting needs a separate Zoho product (Invoice / Books) at extra cost. |
| HR / payroll | Native HR and payroll in the same platform. | Handled by separate products (Zoho People / Payroll), not Bigin. |
| Ease of use & onboarding | Web chat live in minutes; guided setup, though a voice-agent workforce is a bigger idea than a pipeline. | Their strength: set up in under 30 minutes, ~4.6-4.7 ratings on G2 and Capterra. The benchmark for a simple small-business CRM. |
| Pricing model | Flat ₹ plans (₹4,999 / ₹19,999 / ₹69,999 per month) plus pay-per-usage, with broad seat access. | Per seat, billed yearly (pre-GST): Free ₹0, Express ₹400, Premier ₹720, Bigin 360 ₹1,080 per user/mo (USD $0/$7/$12/$18). Cheap, but cost scales linearly with seats. |
| All-in-one scope | CRM + Books + HR/payroll + automation + analytics in one product. | CRM only; full ops means stitching Bigin to Books, People, Desk and others via Zoho One / Flow. |
| India & DPDPA | India-hosted (Mumbai), DPDPA-aligned, INR billing with GST invoices. | Strong parity: Zoho is India-HQ with India data centres, INR billing and GST-ready invoicing across its stack. |

Different tools for different jobs.
These platforms overlap less than the category pages suggest. Pick by the job you're hiring for.
- You're a micro or small team that wants a proven, dirt-cheap, easy pipeline CRM and nothing heavier.
- You're already in the Zoho world and happy to add Books, People and Desk as you grow.
- You value top-rated mobile apps and setup you can finish in an afternoon.
- You want assistive AI to help a human rep, not an autonomous agent running conversations.
No spin: for a small team that wants a cheap, simple, well-loved CRM, Bigin is one of the best in its class.
- You want AI agents to actually answer the phone and chats, in Hindi + English, not just log calls.
- You want one platform for CRM, GST Books and HR/payroll, instead of wiring several Zoho apps together.
- You want autonomous automation across voice, WhatsApp, email and web chat from one agent brain.
- You want native PSTN voice with published per-minute pricing built in.
Bigin is a lovely, cheap pipeline CRM. If the job is just tracking deals, it's hard to beat on price. If you want AI doing the work and your books and payroll in the same place, that's us.
