Unless a business is a monopoly, the sales and turnover of a business depends to a large extent on the following factors:
1. Product price
2. Quality and features of the product
3. Customer support and service
4. Branding or Level of awareness, if your potential buyers are not aware that your product exists, they will not be able to try it out or even send an inquiry. This is true for both consumer and industrial products.
5. Availability or distribution network is important for consumer products. If a lot of money is spent on advertising a particular product or service, but the customer is unable to buy it because it is not available , a lot of extra business is lost.
