I have exactly what you need. When I started my business I was provided a business plan from a wonderful woman at a business enterprise centre.
The plan includes:
Complete business plan and notes on exactly how to complete it.
Financial worksheet with full instructions on how to complete that also.
The plan is in ms word and the financials are in excel and are so easy to use.
You don’t want to get this wrong especially if you are looking to apply for business finance.
