Your Sales Team Works on Their Phone. Your CRM Should Too.
Most Indian sales reps are in the field — at site visits, at client offices, at showrooms. A CRM they can only use from a laptop is a CRM they will not use. 3Sigma is built mobile-first. Every feature works on every Android phone, even in low network areas.

The Reality of Indian Field Sales
A real estate agent in Pune drives between sites all day. An insurance advisor travels to client offices. A solar salesperson does 3 site surveys before noon. None of them are sitting at a laptop.
Without a Mobile CRM
Updates wait until evening
Rep does 5 site visits. Updates all 5 from memory at 9pm. Details are wrong, follow-up dates are guessed, notes are incomplete. By then the manager asked twice.
Calls go unlogged
Rep calls a lead while driving. No way to log the outcome without stopping and opening a laptop. It doesn't get logged. Manager never knows the call happened.
Network areas are dead zones
Rep is at a site with weak 4G. Web CRM times out. They write on paper. Data never makes it back. 3 leads fall through the gap.
WhatsApp and CRM are separate worlds
Customer sends a WhatsApp. Rep responds. Lead status never updates in the CRM. Manager asks for a status update. Rep digs through chats to piece the story together.
With 3Sigma Mobile App
Update on the spot
Rep finishes a site visit. Opens the app. Taps the lead. Adds a note: 'Interested in 2BHK, budget ₹45L, wants to revisit next Saturday.' Takes 30 seconds.
One-tap call logging
Call ends. App prompts: outcome? Rep selects and sets next follow-up. 10 seconds. Manager sees it in real time.
Works on 2G/3G
App stores data locally when network is weak. Syncs when connection returns. No data lost. No frustration.
WhatsApp connected
Customer messages on WhatsApp. Rep sees it in the app, replies from the app, lead status updates. One place. No switching.
A Day in the Field — With 3Sigma
Arjun is a real estate agent in Hyderabad. This is a typical Tuesday.
Opens app. Sees 4 follow-up reminders for today. One lead is flagged hot — they opened the brochure last night at 11pm. He calls them first.
Connected. Schedules site visit for Sunday. Updates status in app with one tap. Confirmation WhatsApp sent to the buyer automatically.
At first site visit. Client asks about a 3BHK floor plan. Arjun shares it directly from the app's document library to WhatsApp — without switching apps.
New lead assigned from 99acres while he's at lunch. Push notification. Calls within 5 minutes. Lead is surprised by the fast response.
Second site visit. Network is weak at the construction site. App works offline. Notes synced when he drives out.
Driving back. Logs 2 more calls by voice note. Manager has seen all 6 interactions from today in real time — without asking Arjun once.
Everything in the App — Nothing Left Out
The mobile app is not a simplified version. It's the full product, designed for a phone screen.
Full Lead Management
View, add, edit, and filter all your leads. Full history of every call, note, and message. Custom fields and tags. The complete CRM experience.
One-tap Calling
Tap a lead to call. Call duration logged automatically. Add outcome and next follow-up date in 10 seconds after the call ends.
WhatsApp Integration
Receive and send WhatsApp messages without leaving 3Sigma. All conversations linked to the lead. No more switching apps mid-conversation.
Document Sharing
Share brochures, floor plans, proposals, and quotes from within the app directly to WhatsApp. One tap to send — from your document library.
Push Notifications
New lead assigned. Customer replied. Follow-up due. Notified instantly on your phone. No lead missed because you weren't at your desk.
Offline Mode
Works without internet. Add notes, log calls, update leads. Everything syncs automatically when connectivity returns. No data lost.
Built for Teams That Work in the Field
Real Estate Field Agents
Arjun manages 8 agents across 3 projects in Noida. His team is in the field from 10am to 7pm. With the mobile app, he sees every site visit, every call, every update in real time — from his own phone.
✓ Manager stopped asking for updates. He just checks the app.
Solar Sales Engineers
Kiran's team does 4-5 site surveys a day across Gujarat. Each survey generates a lead profile, measurements, and a quote request — all entered in the field from the app, while standing on the customer's roof.
✓ Quote turnaround dropped from 3 days to same day. Conversion rate up 40%.
Insurance Field Advisors
Suresh manages 15 LIC advisors across Lucknow visiting clients at homes and offices. Every client interaction logged from the field. Every policy renewal tracked. Suresh sees it all from his own phone.
✓ Zero renewals missed due to unlogged follow-ups.

What Field Sales Teams Say
"My entire team is in the field all day. Without the mobile app, they'd never update the CRM. Now every visit, every call, every note is in the system — entered on the spot. I can see everything without asking anyone."
Rajesh Mehta
Real Estate Sales Manager, NCR
"The offline mode is what sold us. My team covers areas in Rajasthan where internet is unreliable. They enter everything offline, it syncs when they're back on the road. Nothing lost."
Kavita Joshi
Solar Company Owner, Rajasthan
"I check the app before my morning tea. See who called whom yesterday, which follow-ups are overdue, which leads are hot. No morning meeting needed. My team knows I can see everything — and that alone keeps them disciplined."
Deepak Verma
Insurance Branch Manager, Hyderabad
