It depends on the design complexity of the e-commerce website, as well as the number of products and services one wishes to sell through the website, as these factors will determine several important aspects such as development effort, server space required, backend complexity, content management systems, payment gateways, ease of integrating with supplier / partner applications for checking inventory and enabling transactions, customer review management, and so on. Depending on these factors, you can get an e-commerce website designed starting from INR 60,000 (for a basic website) to INR 20 lakhs or higher.
