3Sigma vs Interakt: Full Sales CRM vs WhatsApp Engagement Platform
Interakt helps you send campaigns and manage WhatsApp conversations. 3Sigma helps your sales team close deals — with a real pipeline, SIM-based calling, quotations and invoices, all from one mobile app built for Indian SMBs.
The one-line difference
Interakt is a WhatsApp engagement platform — broadcasts, chatbots and a shared inbox for customer conversations. 3Sigma CRM is a full sales CRM with WhatsApp built in — it runs the pipeline, the calls, the quotations and the invoices alongside WhatsApp. Interakt helps you talk to leads; 3Sigma helps you close them.

The same sales day — two different tools
With Interakt
Suresh runs a building materials company in Ahmedabad and gets enquiries from IndiaMart and WhatsApp. He sets up Interakt to send broadcast messages and manage inbound chats. When a lead replies with interest, there is no pipeline to track them — just a chat thread. His sales team calls interested leads from personal phones; nothing is logged. Suresh cannot tell which leads have been quoted, which have gone cold, or how many calls his team made this week.
With 3Sigma CRM
Same Suresh. IndiaMart enquiries flow directly into 3Sigma, auto-assigned to his salespeople. WhatsApp replies land in the shared inbox. Each interested lead moves through pipeline stages: Contacted → Quoted → Won. The team runs the SIM auto-dialer through their lists — every call logged automatically with outcome and notes. After each call, a popup schedules the next follow-up. Suresh sees quotes sent, deals in progress and calls made — all from his phone while visiting a client in Surat.
Calling, built into the CRM
Indian B2B and service businesses sell on calls as much as on WhatsApp. Interakt is chat-only. 3Sigma puts a full dialer inside the CRM — so your team calls and chats the same lead from one place, with everything auto-logged on the lead's timeline.
SIM-based auto-dialer
Dial your full pipeline list back-to-back on your own SIM — any network, dual-SIM supported. No per-minute cloud telephony bill.
100% auto-logged
Duration, outcome and notes on every call — captured automatically. No manual entry, no calls forgotten in a notebook.
Caller ID + after-call popup
See which lead is calling before you pick up. After the call, set the status and schedule the next follow-up in seconds.
Caller leaderboard
Track calls made, talk time and outcomes per agent — live. Keep your telecalling team accountable with real numbers.

Indian B2B lead sources straight to your pipeline
Most Indian SMBs — manufacturers, service providers, real estate agents — get leads from IndiaMart, JustDial and Facebook, not just WhatsApp. 3Sigma pulls all of them into your CRM pipeline automatically. Interakt does not manage these lead sources in a dedicated sales pipeline.
Quotations and invoices — on your phone
Once a lead is interested, the fastest way to close is a professional quotation in their WhatsApp — right now, from wherever you are. 3Sigma has a built-in quotation and invoice builder on mobile. Interakt does not.
Quotation in two taps
Pick products from your catalog, fill quantities, apply discount — share the quote on WhatsApp directly from the app.
Quote → invoice → order
Convert an accepted quote to an invoice and then an order — full lead-to-cash in one place, without switching apps.
Quotation status reports
How many quotes are pending? How many converted? Track it across your team with the quotation status report.
Which one do you actually need?
Pick Interakt if…
Your primary need is managing high-volume WhatsApp customer communication — sending order updates, broadcast promotions and chatbot flows — and you already have a separate system to manage your sales pipeline and calling, or you don't have a dedicated sales team closing deals.
Pick 3Sigma CRM if…
You have a sales team closing deals — in real estate, manufacturing, insurance, financial services, or any field-sales business. Leads come from IndiaMart, JustDial, Facebook or WhatsApp. Your team calls as much as they chat. You need a pipeline, follow-up reminders, quotations, invoices and a mobile app the team uses on the ground. 3Sigma handles all the WhatsApp broadcasting too, so you get both in one app.
3Sigma vs Interakt — FAQs
What is the difference between Interakt and 3Sigma CRM?
Interakt is a WhatsApp Business API platform built for broadcast campaigns, chatbots and a shared team inbox — well suited for customer engagement and e-commerce notifications. 3Sigma CRM is a full sales CRM with WhatsApp built in, adding a visual sales pipeline, SIM-based auto-dialer, auto-logged call records, quotation and invoice creation, and direct lead capture from IndiaMart, JustDial and Facebook. If your team's job is to close sales deals — not just send messages — you need a CRM.
Is Interakt a CRM?
Interakt has contact management and tagging, but it is primarily a WhatsApp Business API platform for marketing and customer engagement. It does not have a visual sales pipeline with deal stages, a SIM-based calling dialer, automatic call logging, or quotation and invoice tools. For B2B sales teams, service businesses and field sales, a full CRM like 3Sigma is the better fit.
Which is better for Indian sales teams — Interakt or 3Sigma?
For closing sales, 3Sigma. Indian sales teams sell on calls and WhatsApp together. 3Sigma has a SIM-based auto-dialer (dial your full list back-to-back at zero per-minute cloud cost), automatic call logging, caller ID, a visual Kanban pipeline, IndiaMart and JustDial lead capture, and quotation or invoice creation on mobile. Interakt is better suited to e-commerce brands managing customer interactions at scale over WhatsApp.
Does 3Sigma also do WhatsApp broadcasts like Interakt?
Yes. 3Sigma has the complete WhatsApp broadcast stack — bulk campaigns, scheduled sends, approved templates, no-code chatbots and multi-day drip sequences that pause on reply. The difference is 3Sigma does this alongside a real sales pipeline, calling and CRM — not instead of them.
Can I switch from Interakt to 3Sigma without a new WhatsApp number?
Yes. 3Sigma runs on the official WhatsApp Business API and supports WhatsApp Coexistence — you connect your existing WhatsApp Business number, and your contacts and chat history sync into 3Sigma. Your team picks up conversations in the shared inbox with no service interruption.
Which Indian lead sources does 3Sigma capture that Interakt doesn't handle in a pipeline?
3Sigma auto-captures leads from IndiaMart, JustDial, 99acres, MagicBricks, Sulekha and Facebook Lead Ads directly into your CRM sales pipeline — auto-assigned to the right salesperson. Interakt does not manage these B2B and classifieds lead sources in a dedicated sales pipeline.
