If you go with the more simple approach, you’ll need:

A computer

Initial costs. Which would include, costs for the design, development, and hosting of your Web site.

An experience with online marketing. As you are going to want to actively promote your Web site and generate substantial traffic. People are not going to want to purchase advertising or a listing on your site if you are not receiving any Web site traffic.

This approach to starting your own online business brokerage firm is by actively seeking business opportunities for business buyers and investors to review.

This requires a more in-depth knowledge of business fundamentals and excellent sales skills, as you are ultimately negotiating to sell someone else’s business.

 Revenue is typically generated on a commission basis –usually as a percentage of your sales- when you operate at this level.

You list the businesses that you are selling directly on your Web site at no charge. You do this to expose the business opportunities to potential buyers.

Knowledge of business valuations would be an asset.

There are also certifications and professional memberships available for business brokers. If you obtain one of these, it adds tremendous credibility to your business brokerage firm.

You will have to develop professional marketing collateral.

Also, you’ll need to invest more in research and business promotion to find businesses that are looking to sell.

If you are taking the more complex approach, you should monitor the quality of businesses that you are trying to sell. It can take months, even years, to close a business sale, so you want to ensure that you are not wasting any time on a business that will not provide you with a return on your investment. This is especially important because you are typically receiving payment based on sales commissions.
