The short answer is: Yes!
But ultimately, it all depends on companies and the kind of products they sell. If you are interested to sell these companies products online, then you probably want to consider a few important factors before you proceed.
Here are the things for you to consider:
It is important to do a quick background check on them. Online, you can use services that provide such information, for example Alexa, or WHOIS, and consider their legalities before you get involve. Once you obtained some information on the companies, contact them to check for validity.
Proven Track Records
This could be tricky information to obtain. You probably could not get info from a quick visit to the website. Unless the companies were within your vicinity, for you to go and check them up, the best option is to go with networks of companies that have been verified by third parties, for example companies in Cost Per Action (CPA) networks.
Multi-Level Marketing Companies
They are also one of the best choices, provided they can prove to you their track record and legitimacy. In fact, this is the preferred way if you seriously thinking about selling other company products online.
Profitable Product to Sell Online
Some products are not meant to be sold online. People can use online platform to gather leads, but the sales are better consummated off-line. If you want to sell products of other companies this way, you can, but you must make sure you got compensated for the leads you send their way.
The best thing about this, if you choose it, is you do not need to stack up goods to be distributed. A good example of this is drop-shipping business. With this business model, all you got to do is to send leads the companies way, and they will take care of the rest, while you sit back and wait for your commission.
