Fairly obvious youre 20 and have no business experience. What the previous person was trying to say is that it's in your best interest to know all this stuff BEFORE you open your store.
Do you have a written business plan?
Have you laid out all of your operating costs for the first two years? Payroll, rent, utilities, taxes, advertising, surprises.
Did you map out how many phone sales it would take to meet those obligations?
How many more to make a profit?
Do you have an advertising plan?
Sorry dude but it seems like you opened the store cause you heard it would be good and now youre wondering when it will be good.
Here's 2 tips for you.
1., Don't get pissy cause you dont like the comments people make in response to your comments/questions. Makes you look immature.
2. Get your account manager in your store and MAKE them hold your hand and teach you everything. If they wont, go to their boss.
Good luck.
