Retail is a major industry in Western culture, and the retail industry as a whole is a large chunk of consumer spending. Defining retail as a finance project means you will need to give a standard definition of retail at the beginning and move into how retail has changed from what it once was to what it is now. Some avenues of research include how much money is spent on retail and loans and how consumers spend. You can add information about the credit card and online retail shopping and banking.
If you choose to define working capital for your finance project, you will first need to define terms associated with working capital, such as fixed capital and gross and net working capital. You can then define different assets such as stock, bills and cash and explain which category these fit into. Other avenues of research are the advantages and disadvantages of excessive and inadequate working capital and how people tend to budget their working capital.
If you choose to research electronic payments systems, you can do this by defining electronic payment and discussing the popularity of the credit card. Avenues of research include the advantages and disadvantages of using electronic payment instead of cash, electronic payment methods in different countries and rules and restrictions associated with the credit card. When discussing credit scores, you can also mention the requirements needed to apply and receive a credit card and credit. You can discuss company policies and the consumer's awareness of these policies as well.
If you choose to research the stock exchange for your finance project, you will need to start by defining what the stock exchange is and different theories behind it. You can discuss the money market versus the capital market and detail the history of the stock market, including its beginnings, its crash and how it has changed since then. You will want to explain how the stock market works and include the roles and types of stockbrokers and stock trades.
