As with anything, there is a learning curve that applies. When getting started, you have to learn the business.
Make yourself aware of other competitors in your field. Build clientele. Learn if that business has an up and down marketplace or if it remains steady throughout the year. For example, in the moving business, the summer and holidays are the busiest times. In retail, holidays are also a busy time so business hours may increase and sales may apply accordingly.
Items needed for the business you are starting. This depends on the type of business: office building or equipment needed.
Study the annual income and net worth of this? High demand equals successful business. Research: successes and failures of past companies in that business. Cost of what it will be to start and run the business. All these are factors that need to be learned about the business.
You want to stand out and be unique. Need something that will set you apart from the other companies. I don’t think you can be fully prepared for every situation. Unexpected things comes up that you didn’t anticipate.
The better you understand the business, the better the outcome will be. You don’t want to go into something with a blind fold on. That will lead to running into objects and a lot of unnecessary bruises along the way. While preparation is necessary, you will also learn much from experience after starting your business. Some things may be trial and error. For example, one phone system doesn’t work well so you try a different one.
Its takes a lot to start a company but with hard work and dedication, it can be done.
