When developing an eCommerce project, it is important to consider the costs, resources, and timeline. In order to calculate a rough budget and timeline, one should begin by considering the requirements of the project and understanding the expected costs of the eCommerce platform, software development tools, design, hosting and maintenance. Additionally, one should factor in the labour costs and time needed to develop, deploy and maintain the solution. By gathering this information, a rough budget and timeline can then be estimated.
