Economic growth affects consumers' lives and influences their behaviour. Studies show that economic growth positively affects customer satisfaction. Digitisation, on the other hand, has a significant impact on consumer behaviour. It is therefore interesting to examine how an economy like India, which is investing heavily in the IT sector and moving towards greater digitisation, could impact its economic growth. In the era of digitisation, where many day-to-day business activities are carried out online, the importance of information and technology has increased over the years. The contribution of information and technology to GDP has increased sevenfold. But at the same time, the Government of India's spending on the IT sector has also increased by almost 10%. This research paper focuses on the contribution of the IT sector towards economic growth in the form of contribution towards GDP, exports, and employment generation in relation to government expenditure, which not only results in the digitisation of the economy, but also has the potential to alter the Indian consumer’s behaviour..
