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.

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.
