However, the best business plan template is that which meets all your business needs and requirements by offering you a high level of customization and a professional layout of all the content that you would like to include.
Description - What product(s) or service(s) are you offering specifically? Are any patents, copyrights, or trademarks needed? Have they been acquired/filed? What is the size of your business? Where will it be located? Will this require purchasing or building a facility? Will this require leasing a facility? At what cost? Has a lease been negotiated? What personnel will you need? Where will you find suitable employees? What equipment do you need? Will it be purchased or leased? What are the qualifications of your principals? How do their backgrounds promote the success of this venture? Why do they think this will be a successful venture? Possible Data Sources: local Chamber of Commerce; community colleges & local universities; local employee leasing company; real estate agents; US Patent & Trademark Office; US Copyright Office.
Production Operation - If a product must be manufactured, what is the process? Will the work be done on-site or subcontracted? Who are the subcontractor(s)? If on-site, what space, equipment, machinery, production employees are needed? What suppliers are needed? Who are they? How will quality be assured? What is the anticipated production output? What established credit lines do you have? Possible Data Sources: local Chamber of Commerce; yellow pages; trade associations.
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.
