If you do not know this simple stuff, how can you start a business.

You have to start a business only in a field that you know. For example, if you had worked in a flower shop for 2-3 years, and if you know your stuff, you can start a flower shop. If you worked in a beauty saloon for 2-3 years, you can start a beauty saloon, etc.

But if you do not know ABC of cars, how can you start a car repair shop ?

The employment agency charges the customer. This means the Co looking for an employee.
It charges per hour of “usage” of the employee.
What happens is that the employee is an employee of the employment agency, but not of the customer.
The employee is an asset of the employment agency.
So, let’s say you find a company that is loking for an employee.Let’s say you have the perfect match.
So you tell the company, and the company accepts.
You charge the company $25 an hour, but you pay your employee $15
If the company decides that wants to keep the employee, you need to negotiate some paymetn from the company, because you are loosing your asset. Maybe 3 or 4 months worth of payments received if they did not keep the employee.
Now, your challenge is that if you don’t get paid on time..you still need to pay your employee timely…. So you will need to have some cash available just in case. Not all companies pay timely.
Good luck!
