bookeeping of a violin business is simple enough you don't need a computer program, My accountant recommended the Dome monthly bookeeping record, it gives you all the categories you are going to need with your accountant at the end of the year, if you use the record properly your accountant should be able to e file your taxes in about 20 minutes, which costs me about $125, you keep all your expenses on one side, put the number relevant to each expense, then add up all the expenses by category with the number codes, for instance accounting, telephone, utilities, supplies,advertising etc, this is done in the number coded columns at the right side of the page, I do 6 months at a time because my buisiness is sort of slow, but if you're busy you use one of the 12 monthly pages for each month
