We have transformed the traditional calculator into a full-scale Digital POS (Point of Sale) & ERP system.

🔒 3. 100% PRIVATE DATA SECURITY
Your business data is 100% yours.

Zero-Knowledge Privacy: We do not harvest, track, or sell your sales data. No third-party company can ever touch, access, or sell your shop records.

Private Google Drive Sync: Link your personal Google account to activate automatic, encrypted backups. Your database is saved directly to a dedicated, hidden folder inside your own Google Drive.

Total Ownership: Because the backup lives in your personal cloud, you have 100% ownership. It is safe from corporate data miners and ad agencies.

📦 4. BUSINESS ERP, STOCK & LEDGER
Run your entire warehouse and finances from a single mobile hub.

Real-Time Inventory: Automatic stock tracking. The system updates inventory levels during Sales, Purchases, and Returns.

Party Ledgers (Udhaar Book): Track outstanding credits, record partial payments, and pull itemized customer statements in seconds.

GSTR Tax Reporting: Generate automatic tax summaries for GST compliance, broken down by HSN codes and tax slabs.

Multi-Firm Isolation: Manage multiple businesses in one app. Databases are completely isolated—switching firms flushes the cart and shifts the database connection, ensuring records remain private to each business.

🎨 5. PERSONALIZATION
Custom Store Themes: Upload your shop logo or brand banner to use as a custom background behind the calculator keypad.
