Which among the forces in the macroeconomics has the most impact on a company? why?

Gross Domestic Product

Explanation:

Gross Domestic Product or GDP is the most important macroeconomic variable because it measures the amount of goods and services that are produced within an economy in a given year. In other words, GDP is one of the most accurate measures of economic activity that economists have found so far.

GDP impacts companies because they depend on external market forces to stay afloat. If GDP falls one year, this means that economic activity declined, and companies are likely to feel the effects of it in the form of lower sales, lower revenues, less profits, less hiring, more firing, etc.
