WhatsApp AI Bot Pricing in India — 1 Credit = 1 AI Message
3Sigma's WhatsApp AI bot (powered by Gemini 2.5 Flash) uses a simple prepaid credit wallet — top up via Razorpay, spend only what you load, and see every deduction in the activity ledger. No hidden charges, no per-word billing, no surprises.
How the credit wallet works
Neha runs a solar installation business in Jaipur and set up 3Sigma's Gemini bot to handle incoming WhatsApp enquiries. Here is how her credits work in practice:
Load credits into your wallet
Neha purchases a credit pack via Razorpay. Credits appear in her wallet immediately. She can see her remaining balance on the bot dashboard at any time.
Bot replies to a lead — 1 credit used
A lead sends 'What is the cost for a 5 kW rooftop system?' on WhatsApp. The bot reads Neha's pricing PDF and replies with a detailed answer. That reply costs 1 credit.
Lead goes quiet — bot follows up — 1 credit each
The lead doesn't reply for 2 days. The bot sends a follow-up message (within business hours). That is 1 more credit. A second follow-up 2 days later is another 1 credit.
Activity ledger shows every deduction
Neha opens the credit ledger and sees: Lead 'Pradeep Singh', bot name 'Solar Enquiry Bot', reply type 'Follow-up', credits used: 1. Every deduction itemised, no mystery charges.
Top up when balance is low
When credits run low, Neha tops up via Razorpay — UPI or card, same day. The bot resumes automatically. No service interruption beyond the gap when credits were zero.
What's inside the credit wallet
Everything you need to control AI bot spending — without needing to call support to understand your bill.
1 credit = 1 AI message
Simple, predictable billing. Every time the bot replies to a lead on WhatsApp, exactly 1 credit is deducted — no per-character charges, no usage tiers to decode.
Prepaid wallet via Razorpay
Top up anytime using UPI, net banking or card through Razorpay. Credit packs or custom amounts — you decide how much to load. No monthly minimum commitment on credits.
Activity ledger — full credit history
Every deduction is logged: bot name, lead name, message type (conversation reply vs follow-up), timestamp, credits used. Zero ambiguity about where your balance went.
Model picker — cost shown per model
Flash-Lite, Gemini 2.5 Flash, 2.5 Pro — each shows its credit cost per message before you select. Use a lighter model for simple FAQ bots, a heavier model for complex qualification.
Auto follow-up credits (same rate)
When the bot sends a scheduled follow-up message (because the lead went quiet), it costs 1 credit — same as any other AI message. Business-hours scheduling means no wasted credits at odd hours.
Test Chat is free
Running Test Chat to check your bot against uploaded files before going live does not use live credits. Set up, test and refine until you're confident — then switch on without worrying about wastage.
What affects how many credits you use per month
Credit usage varies by how active your bot is, not by the size of your knowledge base or the number of bots you set up. Here is what actually drives your monthly spend:
Volume of incoming leads
High impactMore WhatsApp enquiries = more bot replies = more credits. A business with 200 leads/month uses more credits than one with 20.
Auto follow-up frequency
Medium impactMore follow-up messages per lead (e.g. 3 follow-ups vs 1) use more credits. You control the follow-up pace setting.
Gemini model selected
Medium impactFlash-Lite costs fewer credits per message. Gemini 2.5 Pro costs more. The model picker shows each model's rate before you select.
Number of messages in a conversation
High impactA lead that asks 5 questions in one session = 5 credits used by the bot. A lead that asks 1 question = 1 credit.
Knowledge base files uploaded
None impactUploading more files does not cost credits. Only bot replies to leads use credits.
Test Chat during setup
None impactTesting your bot before going live uses a separate sandbox — it does not deduct from your live credit wallet.
Credit wallet vs subscription billing — why 3Sigma uses credits
Many SaaS tools charge a flat monthly subscription for AI features regardless of how much you actually use them. 3Sigma uses a credit wallet because AI message volume varies a lot — an insurance agent handles 50 leads/month, a real-estate developer handles 500. Prepaid credits match cost to actual usage.
| Factor | Flat subscription | Credit wallet (3Sigma) |
|---|---|---|
| Pay when you use it | Charged even on low-volume months | Credits used only when bot replies |
| Cost scales with usage | Fixed cost regardless | ✓ — credits match actual volume |
| See every charge itemised | Often opaque | ✓ — activity ledger per message |
| Choose model per bot | Usually one tier | ✓ — Flash-Lite vs Flash vs Pro |
| Top up anytime via UPI/card | Monthly invoice | ✓ — instant Razorpay top-up |

WhatsApp AI Bot Pricing — FAQs
How does 3Sigma's WhatsApp AI bot pricing work?
The AI bot uses a prepaid credit wallet. Every AI message sent by the bot costs 1 credit. You top up your wallet via Razorpay — packs of credits or a custom amount. When your credits run out, the bot stops sending AI replies until you top up. There are no surprise invoices; you spend only what you load.
What exactly counts as 1 AI message?
One AI message = one reply sent by the AI bot to a lead on WhatsApp. When a lead sends a message and the bot responds, that is 1 credit used. If the bot follows up automatically (because the lead went quiet), each follow-up message is also 1 credit. Test Chat conversations during setup do not count as live credits.
Is the AI bot included in the base 3Sigma CRM plan?
The WhatsApp AI Bot is available on eligible 3Sigma accounts, controlled by an org-level setting (isAIEnabled). It is not switched on by default for every account. Speak to the 3Sigma sales team to check availability and pricing for your organisation.
How do I top up my credit wallet?
Inside the 3Sigma app, navigate to the AI Bot section and open the credit wallet. You can purchase credit packs or enter a custom amount — payment is via Razorpay (UPI, net banking, debit/credit card). Credits are added instantly after payment.
Can I see exactly how credits are being used?
Yes — the credit wallet includes an activity ledger that shows every credit used: which bot sent the message, on which lead, at what time, and whether it was a conversation reply or an auto follow-up. You can see the full history without contacting support.
Does using a more powerful Gemini model cost more credits?
Each Gemini model has a different credit cost per message, shown in the model picker before you select. Gemini 2.5 Flash (the default) is the standard baseline. Flash-Lite costs fewer credits per message. Gemini 2.5 Pro costs more. You pick the model per bot based on your use case and budget.
Does the number of files in the knowledge base affect credit usage?
No — uploading more files to the knowledge base does not cost credits. Credits are only spent when the AI bot sends a message to a lead. Uploading PDFs, running Test Chat during setup, and browsing the bot interface are all free.
What happens to unused credits — do they expire?
Speak to the 3Sigma sales team for the current expiry and rollover policy on credit packs. Credit terms can vary by pack type. The activity ledger always shows your remaining balance.
