I want to share my experience in my retail business before the age of the internet. My plan seemed complete and my capital looked enough. But after a few months of good sales, I was deluged with new customers that may be the result of word of mouth. I had to borrow money for the supplies that were purchased. Sooner than I expected, the interest of the money borrowed was eating the profits. If only I had more than enough capital my business would still be alive today. The lesson learned is the amount of capital that you will use for your business should be more than enough.
