The Problem

The data exists.
Merchants can't access it.

Every kirana owner has transaction data in Paytm. But unlocking a phone, opening an app, and navigating mid-sale is impossible.

📱

App is too far away

Merchants check revenue by double-pressing the Soundbox button, not opening the app. Hands are always busy.

Friction kills insight
⚡

Disputes happen in real-time

"Customer bola payment nahi hua" - every week. Verifying means finding the phone, opening history, scrolling.

#1 merchant pain point
📊

Trends stay invisible

Merchants don't know their peak hours, slow days, or whether this week was better than last - unless they dig.

Decisions made blind
🏦

Loan eligibility is a mystery

Paytm has the data to say "you qualify for ₹80,000" - but merchants never hear it proactively.

How It Works

Voice in. Intelligence out.
No app needed.

Built on Paytm's own Inference API. Runs on the Soundbox they already have.

1

Merchant speaks

In Hinglish, naturally - "Aaj kitna hua?" or "Loan milega?"

2

Voice is transcribed

Web Speech API (hi-IN locale) converts speech with 90%+ accuracy on Hinglish

3

LLM reasons over data

Paytm Inference API (llama-3.3-70b) answers with exact numbers from transaction history

4

Soundbox responds

2–3 sentence Hinglish answer - specific, warm, actionable. Like a trusted munshi.

Use Cases

Five questions.
One device answers them all.

These are real queries from kirana owners. The CFO handles each in under 3 seconds.

₹

Daily Revenue Check

"Aaj kitna hua?"
Aaj ₹3,400 aaye, 21 transactions. Peak time 7 se 9 PM tha. Kal se 41% kam tha - Saturday tha na.
📈

Weekly Trend Analysis

"Is hafte kaisa raha?"
Is hafte ₹26,680 aaye - pichle hafte se 12% zyada. Best day tha Friday, ₹5,800 ke saath.
⚡

Payment Dispute Resolution

"Customer bola payment nahi hua"
Aapki last transaction ₹340 thi, aaj 7:22 PM pe, UPI se - confirmed received. Customer ko dikhao, payment hua hai.
🏦

Loan Eligibility

"Mujhe loan mil sakta hai?"
Haan Ramesh bhai, ₹80,000 tak eligible ho. Consistency bahut achhi hai - 30 mein se 28 din active the. Paytm app mein apply karo.
📊

Behavioral Insight

"Aaj itna slow kyun tha?"
Tuesday hamesha thoda slow hota hai - last 4 weeks ka data yahi bol raha hai. Average Tuesday ₹3,100 hota hai, aaj ₹3,400 tha - actually better tha.
👥

At-Risk Customers

"Koi regular nahi aa raha?"
Teen regular customers 14+ din se nahi aaye - Morning Chai Wala, Evening Milk Uncle, Sunday Sabzi Lady. Unhe remind karo.
