The nature of running a business is such that nothing is unimportant. If you are a small business owner and you keep your own accounts, or you hire an accountant to do it for you, you will know that everything costs money and that every purchase makes a difference. Whatever your revenue is, it will be reduced every time you decide to buy something as modest as a stapler. That is why successful business people are also sensible with their money. You need to have a great attention to detail if you are going to make your business as profitable as it can be. While lots of things may not seem important, they all add up, and if you have a rather laissez-faire attitude towards the small things, they will soon accumulate together a become a big problem. While being parsimonious or miserly often has a rather unflattering connotation, the fact is that it is just good practice.
