This training manual provides instructions for store sellers to process customer orders on the Paytm Mall platform. It outlines the four stages of order processing: order received, pickup code, delivered, and handover to customer. Sellers are instructed to click through several order tabs to confirm, pack, and create packages for orders. They then check customer details, payment mode, and enter tracking details. Finally, orders are marked as delivered by clicking the "Handover Package" button. The process ensures orders are fulfilled and customers can check their pickup codes in the app to collect items.
