I know you are just spit ballin here.
But you have missed LOTS of expenses.
Do yourself a favor and do a REAL business plan.
The last time I did one for our store, it took a few months to put it together, and that was with help.
And we still missed things.
Accountant, book keeper, Napkins, Toilet paper, Soap, Those stupid little rolls of paper that go in your credit card machine….. the credit card machine, the cut that those companies take, the phone line, internet connection, tv/ cable, plates, cups, cutlery ( either disposable or washable ) mops, pails, cleaning solutions, office supplies, computers, paper, printers, ink, light bulbs, pens, markers, payroll services, trade shows, loyalty cards….ADVERTISING.
These are just the tip of the list off the top of my head that we did not have in the biz plan.
Heck if you had a receipt printer AND a credit card machine like we do ( 2 different sizes of paper ) and you were doing even HALF of your projections, then each roll would last about 3 days.
my 2 cents :0
