Managing an online business can very often be complicated. Here are only some of the things you will need to remember about while managing your online business:

-Customer service. If you are the only person managing your online business, you are also the only customer service member your business has.
-Contacting your suppliers. Unless you manufacture the goods you sell, you will have to be in contact with your suppliers at all times.
-Building relationship with important clients. Using postcard mailing services may be a good idea if you want your clients to feel special.
-Visitor monitoring. It is up to you to monitor how many people visit your website and how many visitors purchase your products. You will always want to see more people visiting your online business, so you will also have to take care of marketing and promotion of your online business.
-Sales strategy. You are the only one who has to take care of planning as well as putting in practice everything you need to implement your strategies.
-Building your online and offline presence.
