iSmartSync is a Shopify-integrated POS for multi-branch retail businesses in Pakistan. When a sale happens in-store, inventory deducts instantly at the branch and updates in Shopify simultaneously — keeping online and offline stock always in sync. For Shopify online orders, inventory deducts only when staff picks and packs from a specific branch, preventing overselling and COD return mismatches. Features include multi-branch inventory management, branch-to-branch stock transfers, purchase orders, RMA and returns, counter billing, shift-based cash control, salesman commissions, and loyalty programs. FBR e-invoicing is built in — generating compliant invoices and automatic credit notes on refunds. AI-powered analytics provide real-time visibility across all branches without manual reconciliation. Compatible with fashion, footwear, apparel, electronics, cosmetics, and general retail — from single-branch stores to growing multi-location chains, with flexible add-ons to scale.
