Who Uses UdhaarBill?

Built for the diverse ecosystem of Indian small and medium businesses.

๐Ÿ›’ Kirana Stores & FMCG Retailers

Kirana stores handle hundreds of small transactions daily. Writing these down in a paper khata leads to mistakes, lost entries, and delayed payments. UdhaarBill allows kirana owners to add daily udhaar instantly, send weekly WhatsApp payment links to customers, and track inventory. With our digital khata, kirana stores recover their pending dues 40% faster.

๐Ÿ’Š Medical & Pharmacy Shops

Medical stores require strict compliance with GST and expiry tracking. UdhaarBill provides specialized GST billing formats that include batch numbers and expiry dates. Generate professional invoices for chronic patients and track their monthly udhaar accounts effortlessly.

๐Ÿ‘— Garment & Textile Retail Shops

Textile merchants in markets like Surat and Ahmedabad deal with complex HSN codes, multiple tax brackets, and B2B wholesale transactions. UdhaarBill simplifies this with auto-calculated SGST/CGST, bulk invoicing, and easy sharing of PDF bills directly via WhatsApp.

๐Ÿšš Wholesale Distributors

Distributors managing supply chains to hundreds of retailers need robust credit management. UdhaarBill tracks outstanding balances across your entire network, sends automated bulk payment reminders, and generates compliant e-way bills and professional B2B tax invoices.

Why Businesses Are Switching from Paper Khata to Digital Khata

The traditional red diary is holding your business back.

For generations, Indian businesses have relied on the traditional paper ledger (Bahi Khata) to track customer credit. However, as business scales, this manual method becomes a massive liability. Here is why over 50,000 businesses have made the switch to UdhaarBill's digital khata software:

1. Complete Protection Against Data Loss

Paper diaries can be lost, damaged by water, or misplaced. When you lose your khata, you lose your money. UdhaarBill features 100% cloud backup. Your data is synced securely in real-time. Even if you lose your phone, simply download the app on a new device, log in, and all your customer balances and invoices are instantly restored.

2. Elimination of Calculation Errors

Adding up hundreds of small entries manually leads to human error. A calculation mistake means either you lose money, or you overcharge a customer and lose their trust. UdhaarBill's automated ledger does the math for you with perfect accuracy every single time.

3. Faster Payment Recovery (Vasuli)

Calling customers to ask for pending payments is awkward and time-consuming. Our automated WhatsApp and SMS reminder system sends polite, professional payment requests with exact invoice details and UPI payment links attached. Our merchants report collecting outstanding udhaar up to 3x faster compared to manual phone calls.

4. Professional Business Image

A handwritten slip doesn't inspire confidence in 2026. Generating a professional PDF invoice with your business logo, GST details, and digital signature elevates your brand. Customers are more likely to pay on time when presented with a formal, professional bill.

Core Capabilities: A Complete Business Operating System

Advanced GST Billing & Invoicing Software

Creating GST-compliant invoices shouldn't require an accounting degree. UdhaarBill's billing engine is designed for speed. Create tax invoices, bill of supply, proforma invoices, and quotations in under 15 seconds. The system automatically detects intra-state vs inter-state sales and applies the correct CGST, SGST, or IGST. Add HSN/SAC codes with ease. Print physical copies directly from your phone using a thermal Bluetooth printer, or share digital PDFs via WhatsApp instantly.

Smart Digital Khata (Ledger) Management

Managing credit and cash flow is the lifeblood of a retail business. The Digital Khata module allows you to add customers from your phonebook, record 'You Gave' and 'You Got' transactions, and view a live dashboard of your total market credit. Every transaction is time-stamped and secure. Customers receive an instant free SMS alerting them of the transaction, ensuring complete transparency and trust.

Inventory & Stock Management

Prevent stockouts and overstocking. UdhaarBill tracks your inventory in real-time as you generate bills. Get low-stock alerts directly on your dashboard. Categorize items, manage multiple pricing tiers (wholesale vs retail), and track your most profitable products. The built-in barcode scanner lets you use your phone's camera to scan items for lightning-fast billing at the counter.

Comprehensive Reporting & Analytics

Data drives growth. With UdhaarBill, you don't need to wait for your CA to tell you how your business is performing. Access real-time reports on daily sales, monthly revenue, profit margins, outstanding receivables, and GST tax liability. Export these reports to Excel or PDF with one click to share with your accountant.
