What is the main source of capital for sole proprietorship?

Sole proprietorships are not companies – you cannot sell shares to investors to raise capital. _ Most times, you'll be relying on your own resources, such as savings and retained profits, as well as bank loans and credit cards to raise the money you need.

Explanation:

Sole traders and partnerships have a range of options to get finance: personal savings, retained profits, working capital, sale of assets, and bank loans. Put simply, personal savings is the the amount of money a person has at his disposal.
