The copper mining company needed to increase operational efficiency. They used Excel sheets to manage customer data, making it difficult to keep up with dynamic business needs. Sales data was only compiled monthly, which was time-consuming and error-prone. Sigma implemented a customized sales force automation solution using technologies like Grails and MySQL. This centralized the customer database, provided customizable reporting, and removed manual data entry. As a result, the company improved sales forecasting, customer service, and visibility of sales operations.
