So, although a detailed business plan may not be required for an online business, I am going to include it here so you can at least look at and consider each section and determine yourself if it applies to your business.
The three basic actions for growing a business in any economic climate are: improve efficiency (maintain output while reducing inputs, such as time and money); increase volume (produce more in order to spread fixed costs); reorganize the business (change goals, methods and/or philosophy). If you plan to implement one of these, you may as well plan to implement them all. By focusing on one of the above strategies, you will find a ripple effect that causes a need to address the others. This is a good thing.
Every Business Needs a Plan _ Without a plan, there is little hope for growth, let alone survival. As my small business development counselor, Terry Chambers says, "If it's not written, it's not real." That doesn't mean it's unchangeable, but it does show that you mean business. In order to accomplish your strategies of improving efficiency, increasing volume, and reorganizing your business, you've got to examine what you have, what you want, and how you plan to get there.
When you sit down to compile all of the elements of your business plan, make sure you have each section able to stand on its own merits. This means you should not reference other sections sending the reader (your potential investor) back and forth between sections.
