One of the e-Commerce benefits is that it has a lower startup cost. Depending on what type of e-Commerce business you run, you may only need to hire employees when you grow to a certain level. As your online store is online, these employees can work remotely, making it easier to find staff that will suit your company. If you choose to dropship online, you won't need to buy bulk inventory saving you a lot of money.
Online stores are always open for business. Think about your audience, those who do not work normal hours or are too busy to pop into a shop to buy something. An e-Commerce store allows you to attract those who may have an odd work schedule or simply those who don't have time to shop in-person.
Next on the list of e-Commerce benefits is that your new brand can easily sell to customers worldwide. Selling worldwide is a great feat as it helps build your brand a lot faster, broadens your marketplace exponentially, and allows you to see profit long before your local competitors.
