Shipping and fulfilment is about how an order physically reaches the customer — which courier service carries it, how tracking works and how long delivery takes.
Delivery-rate configuration is about what the customer is charged for delivery at checkout — a fixed fee, a distance-based charge, a slab-based rate or free delivery under certain conditions.
BharatGo handles both, but they are separate concerns. You choose your shipping partner for fulfilment, and you configure delivery rates to control what customers pay.
