A product or a service
Well, you might have a killer business plan and well conversant with the target market. But if you do not have any product you are offering, you might be the new joke in town. A business exists to solve a problem in the market. The product/service you will be offering is the solution to the problem/s. Remember, the high the problem you will be solving, the more profit you will earn. Also, the product is the magnet that pulls customers to your online store. So, only a mad person can visit your shop if you have nothing to offer in exchange for their cash. Note, your product must be realistic and on-demand in your target market.
Marketing and distribution channel
After having a product/service, you have a role to inform your target market about its existence. You cannot set up an online store and wait for customers to come without any awareness creation efforts. Also, you must have ways of taking the product to the consumers. In this essence, marketing and distribution channel identification is critical for an entrepreneur seeking to sell online successfully. In a word, for you to sell online successfully, you need a business plan. Also, you must identify a target market, a product to offer, and embark on awareness creation.
