My accountant doesn't use sage but I do what info do I give them at the end of the year?

Whatever they need. It depends on what you are asking the accountant to do at the end of the year. If accountant is just certifying your books he just may need a print out of your ledger. If he is doing your taxes he'll also need depreciation of assests and any new assest purchases made. If he's doing W-2s for employees he'll need all of your employee info and pay stub/info.

Call your accountant and ask him/her this question.
