Under the hood

Six AI tools working together
so you don't have to.

Hisaab isn't a single model bolted onto a form. It's a coordinated AI pipeline built around how vendors actually communicate.

AI capabilities

What the AI actually does

Each tool in the pipeline handles a specific part of the vendor's journey.

Input
๐ŸŽ™๏ธ

Speech-to-Text

Vendors send voice notes in Hindi, Tamil, or Telugu. Hisaab transcribes and understands them โ€” no typing required.

Input
๐Ÿ“ธ

OCR & Document Extraction

Photos of supplier bills, receipts, or inventory lists are automatically read. Amounts, dates, and items extracted without any form-filling.

Understanding
๐ŸŒ

Multilingual NLP

Understands natural-language requests like "mujhe kal ke liye 8,000 chahiye" โ€” intent, amount, and urgency all extracted from free text.

Analysis
๐Ÿ“Š

Cash-Flow Estimation

Instead of trusting the requested amount blindly, AI estimates real working-capital need from bill amounts, business type, and sales patterns.

Decision
๐Ÿ›ก๏ธ

Risk Scoring

Builds a Trust Score from alternative signals โ€” conversational consistency, document quality, repayment history โ€” instead of a CIBIL check.

Output
๐Ÿ“…

Repayment Recommendation

Generates a repayment plan calibrated to daily income cycles โ€” not monthly salary schedules. Explained in plain language in the chat.

Getting started

Your first loan: four things we need

Before Hisaab can extend a first loan, we verify your identity and establish a baseline of your business activity. This is done entirely through WhatsApp โ€” no branch visit, no scanning portal.

๐Ÿชช

Your PAN Card

Send a photo of your PAN (Permanent Account Number) card. PAN is issued by India's Income Tax Department and serves as the primary KYC identity document for financial services.

Sole proprietors use their personal PAN โ€” your name is the business name for KYC purposes.
Registered firms, LLPs, or Pvt Ltd companies should provide the business/firm PAN, which is a separate 10-character number issued to the entity.

๐Ÿคณ

Live Selfie โ€” Matched to Your PAN

Take a short live selfie via WhatsApp. Hisaab's identity verification checks that your face matches the photo on your PAN card, confirming you are the cardholder and preventing impersonation.

The check is done in real time โ€” the system compares facial geometry against the PAN photo. A static photo of someone else won't pass. This step is required by RBI guidelines for video/image-based KYC (V-CIP).

๐Ÿงพ

3 Recent Paid Invoices

Share photos of three recent paid supplier or customer invoices. They must be in the same name as your PAN โ€” either your personal name (sole proprietors) or your registered business name.

These confirm your business is active, show realistic transaction volumes, and give the AI a starting point for estimating your working-capital needs.

๐Ÿ“‰

Initial Loan Limits

Your first loan is capped based on the invoice history you provide. As you repay and continue sharing bills, your Trust Score grows and your available limit increases automatically.

Starting small is intentional โ€” it protects you from over-borrowing and builds a verifiable repayment track record that unlocks higher amounts over time.

Why PAN? PAN is mandatory for all financial transactions in India above โ‚น50,000 under the Prevention of Money Laundering Act (PMLA). NBFC lending partners require it for RBI-compliant KYC. Your PAN is never shared with third parties beyond your lending partner.
The differentiator

Trust Score: credit for the uncredited

Over 190 million Indian micro-vendors have no formal credit history. Traditional lenders can't see them. Hisaab's Trust Score is built entirely from alternative data that reflects how they actually run their business.

Responsible lending

AI decides fast. Humans catch edge cases.

Applications with low confidence scores, unusual patterns, or fraud signals are automatically routed to a credit officer for manual review. The AI doesn't pretend to be perfect.

๐Ÿค–

Automated (majority)

Clear profiles with consistent signals get instant decisions. No waiting, no callbacks.

๐Ÿ‘ค

Human review (edge cases)

Low-confidence scores, first-time applicants with thin data, or anomaly flags route to a credit officer dashboard.

๐Ÿ“‹

Officer dashboard

Credit officers see the AI's reasoning, the extracted data, and the vendor's full chat context โ€” not just a raw score.

Architecture

How it's built

A lightweight but production-ready stack designed to scale across millions of WhatsApp conversations.

๐Ÿ“ฑ

Interface

WhatsApp Business API โ€” handles text, voice notes, and image messages in a single thread.

โš™๏ธ

Backend

Loan workflow engine: onboarding, KYC, eligibility, underwriting, disbursement, collections, reminders.

๐Ÿง 

AI Layer

STT, OCR, multilingual NLP, cash-flow model, risk scorer, repayment engine โ€” each a specialized model.

๐Ÿ“‚

Data Inputs

Chat history, voice transcripts, bill images, KYC docs, repayment records, optional bank/UPI data.

๐Ÿ‘จโ€๐Ÿ’ผ

Human Review

Credit officer dashboard receives routed cases with AI reasoning, confidence scores, and vendor profile.

๐Ÿฆ

Lending Partner

NBFC or bank partner holds the license. Hisaab is the UX + AI layer. Regulatory compliance built in.
