A business plan excel spreadsheet on a salon
I am currently taking a class where I need to complete a business plan excel spreadsheet for a futuristic salon. I already have the excel spread sheet formatted the way it needs to be I just don’t know the first thing about a business plan or the information necessary to get a good enough grade.
I just need it filled out and to make sense in some form way or fashion. I uploaded the LCC excel spread sheet which is the one that needs to be completed as well as an example of a random salons business spread sheet that is completely filled out.
