Inventory: Stock entry, purchase bills, stock transfers across branches, manufacturing/assembly, stock conversion (bulk-to-retail), low-stock alerts.

Accounting: P&L, Balance Sheet, sales/purchase/expense reports, Tally integration.

CRM: Enquiries, lead tracking, customer database with history and outstanding invoices.

Tasks & Calendar: Assign tasks, reminders, visual calendar for follow-ups/meetings.

Barcoding: Generate/print barcodes, integrate barcode scanning at POS.

WhatsApp Integration: Automated reminders, invoice/order updates, API-based messaging.

Staff Commission: Auto-calculate seller/executor commissions (1.5% & 0.5%), with detailed reports.

This will be an all-in-one ERP-style system for sales, billing, inventory, accounting, CRM, communication, and staff commission tracking.
