Convincing other people about the products we market is not an easy thing to do and the products we offer must of course be of good quality so that we can offer them to other people. Building a business certainly requires capital and this really depends on the business we are going to build.
That's why there are strategies in marketing and someone has to learn that depending on the experience that he's got.
Aside from the quality, you really have to build network and connection to your future and potential customers and prospects.
No matter what people say, money is always needed in business. Some businesses close just because they do not have enough money to operate anymore even if the concept of the business is good. A good business idea does not always mean it will be profitable immediately.
This is why you should partner up with other people who would be invest in your business. Yes you would be splitting up the profit but at least you’ have enough funding.
