    Your sale already runs on a system. It's just a broken one.

    A lead comes in on IndiaMart. Someone copies it to Excel. The conversation happens on a personal WhatsApp. The call is made from a phone nobody logs. The quotation is made in Word. The follow-up lives in one person's head. Nothing is connected — so leads leak at every handover.

    3Sigma replaces all six with one system your team runs the day on.

    A lead arriving, a call being made, a follow-up firing and an invoice going out — all on one record.

    One system, one record

    HOW THE SALES OS WORKS

    Follow One Lead From Enquiry to Invoice

    This is the actual path a lead takes through your business. At every stage the tool that does the job is already here — so nothing is copied into another app, and nothing is lost at a handover.

    STAGE 1 — THE LEAD COMES IN

    Every lead lands in one place, on its own

    Your enquiries arrive in a dozen different places. This is where most of them are already lost — because someone has to notice and copy them somewhere. Here nobody does.

    Leads captured from every source
    STAGE 2 — IT REACHES THE RIGHT PERSON

    Assigned in seconds — automatically or by you

    A lead sitting unassigned is a lead going cold. Set the rule once and it routes itself the moment it arrives, or assign by hand when you want to decide. Either way, someone owns it immediately.

    Automatic lead assignment to the team
    STAGE 3 — LEAD MANAGEMENT

    One record that holds the entire relationship

    Every call, message, note, document and follow-up for that customer sits on one timeline. Anyone who opens it knows exactly where things stand — including the person covering when your rep is on leave.

    Complete lead record and timeline
    STAGE 4 — ENGAGEMENT & FOLLOW-UP

    You reach them — and keep reaching them

    In India the sale happens on WhatsApp, so it isn't a plugin here — it's built into the same record as the call log. And the follow-up fires whether anyone remembers it or not, because most deals are lost to silence, not to a competitor.

    WhatsApp API, campaigns and calling
    STAGE 5 — SALES ACTIVITIES & CLOSING

    Quotation to invoice, without leaving the record

    This is the last mile where most teams switch to Word and a separate billing tool — and the record goes stale exactly when the deal matters most. Here the paperwork stays attached to the customer.

    Quotations, invoices and orders

    Five stages. One record. That is the whole idea.

    And running across all five are three things that do the heavy lifting — WhatsApp, your AI bot, and everything you need to run the team itself.

    THE LAYER UNDERNEATH ALL SIX

    The Official WhatsApp Business API, Built Into the CRM

    In India the sale doesn't happen on email. It happens on WhatsApp — the enquiry, the negotiation, the brochure, the payment reminder, all of it. That's why WhatsApp isn't a feature sitting next to this CRM. It's the layer the whole system is built on.

    Official WhatsApp Business API inside 3Sigma CRM

    Keep your number. Keep your chats.

    The biggest reason teams avoid the API is losing the number their customers already save and the history sitting in it. With WhatsApp Coexistence you connect your existing WhatsApp Business number — your contacts and chat history come across, and your team keeps using the app on their phone at the same time.

    Message at scale without getting banned

    Broadcasting from a personal phone is how numbers get blocked. This is the official API — a verified business profile, green-tick eligible, Meta-approved templates and rate-limit-aware sending. We set the API up with you.

    One inbox the whole team shares

    No more customer conversations trapped on one person's phone. Chats are assigned, filtered and answered by the team — and every message is logged on that customer's record alongside their calls.

    An AI bot that answers while you sleep

    Upload your brochures and price lists as the bot's knowledge base, and it replies to enquiries, qualifies them and follows up on its own — in your words, within your business hours.

    LAYER 2 — THE AI BOT

    An AI That Answers Your Leads at 11pm

    Most enquiries come in after hours, and the ones that wait until morning have already messaged your competitor. Your AI bot reads your own brochures and price lists, replies in your words, qualifies the lead and hands it over — before anyone on your team has woken up.

    It learns from your own files

    Drag in your brochures, price lists and FAQs — PDF, Word, Excel or images. That becomes the bot's knowledge, so it answers about your products, not generic nonsense. Test it in a chat window before you ever put it live.

    It writes its own instructions

    You don't need to know how to prompt an AI. Answer two questions about your business and it drafts the bot's full instructions for you — then you refine it by chatting, in plain language.

    It follows up on its own

    Set the goal, the tone and the pace — gentle, balanced or persistent — plus your working days and business hours. It chases the lead politely until they reply, and stops when they do.

    It actually updates the CRM

    This isn't a chatbot bolted onto a website. Mid-conversation it can add a note, change the lead's status, create a task or move the lead — so the record is current the moment your rep opens it.

    AND IT KEEPS GETTING BETTER

    It grades itself every night

    Every conversation is scored against the goal you set, with a pass or fail and the top issues listed.

    It suggests its own fixes

    Those issues become suggested improvements you can accept or reject, with a before-and-after view. Reversible any time.

    You stay in control

    Pick the model, see the cost per message, and pay only for what it sends from a prepaid balance.

    LAYER 3 — THE TEAM ITSELF

    You're Not Just Managing Leads. You're Managing People.

    A CRM that only tracks leads leaves out half your job. Who turned up today, who is actually at a customer right now, who is behind on target, and who made the most calls this week — that's the other half, and it's in the same system.

    Live tracking — the map answers first

    Stop calling reps to ask where they are. Every active rep is on one map with their current status, each visit checks in against the real customer record, and you can replay any day's route. Tracking runs only during the work day and switches off in the evening.

    Attendance — without a register or a biometric machine

    Your team checks in and out from the same app they already use for leads, with GPS location and a photo. You decide what gets captured and whether location is compulsory — useful when half the team never comes to the office.

    Targets you find out about before month-end

    Set a monthly target per person and watch goal-versus-actual fill up live. The month is still fixable on the 12th. It isn't on the 30th.

    See Sales Targets →

    A leaderboard your team can see

    Calls made, talk time and rankings, updated as the day goes. Nothing motivates a calling team like knowing where they stand.

    WHERE THE OS RUNS

    The Whole System,
    In Your Team's Pocket

    Indian sales teams don't sell from a desk. So this isn't a cut-down mobile companion to a web CRM — the full system runs on the phone. Leads, calls, WhatsApp, quotations and reports, all of it, on Android and iOS.

    Works without network

    Log the call at a site visit with no signal. It syncs when you're back online.

    Your team already knows how

    It works like the apps they use daily. No training week, no resistance.

    CONFIGURED FOR YOUR BUSINESS

    A property site visit, an admission enquiry and a loan file are not the same sale. Custom stages, fields, statuses and templates mean the system speaks your industry's language instead of forcing you into someone else's.
