There are a number of ways of going about the process of writing a good business plan. One of the most tried and time tested ways that works well is using a business plan template.
While these are easily available online, some of them are way better than the others. A lot depends on the approach that goes into writing the business plan.
So this is a very user-friendly method too. The content includes eye-catching graphics which are placed purposefully to magnetize the attention of viewers whereas good content is written to complement the graphics to make website interactive. Maintenance of a website template is so easy. Normal changes in the website can be done without any problem and without even changing layout of your website.
So, rather than looking around for an existing plan and then designing your own plan along the same lines, it would be a better idea to use software that allows you to create your own template.
