In Marketing, DSA stands for Direct Selling Agent. DSA is an abbreviation of Direct Selling Agent. A direct selling agent or DSA is a person who works as a referral agent for a bank or NBFC. They are marketing agents who bring business to the banks. The job of a DSA is to find potential customers for the bank they represent. To do this, DSAs will look for people who are in the market for a loan. These leads are then directed to the concerned bank or NBFC and the loan process is taken forward. For the effort put in by the DSA, a payout is provided. This payout is a percentage of the type of loan and the loan amount. And this payout is a great way to earn a little extra cash. In rural areas, DSAs are known as business correspondents. Thus, option 3 is the correct answer.
