When there are big businesses, there are also small ones. the most common reasons include the following: lack of capital or funding, retaining an inadequate management team, a faulty infrastructure or business model, and unsuccessful marketing initiatives. I agree with these reasons for these were the causes why my brother failed in his small business. He retained those people who are not functioning well. His capital was also not sufficient to back up a marketing strategy. Marketing initiative is very necessary to avoid failure. Were you having a small business before but failed? Which among the reasons why your business failed?
