Software to an office is the same as a power drill is to a contractor. Doubtless, he can make holes and turn screws without using power tools, but it will take him much longer to accomplish the same task. And, the results are usually not as clean.
It is the same with software. You can create documents and charts by hand, but it will take you longer and your work will be immediately perceived as being sub-par.
Using such products as Microsoft Office (an integrated suite of applications) will allow achieving better results in a shorter period of time. Using an accounting system will allow you to manage your finances, business resources and create more presentable documents for your customers. Using a product like Microsoft Project, will allow you manage your people, equipment and projects more effectively.
