Have you given soap away and got feedback.
Is there too many selling soap in your area.
Do you have enough time to keep and get a range of soap.
What makes your soap different from others to get sales.
Are you relying on this for income.
Have you researched who is selling in your area.
Do you have enough capital to buy supplies in bulk to save money.
Have you any business background or have had other businesses.
Keeping of books for tax purposes (again depending on your country).
