How old is she?
I wouldn't pay her for good behavior - that just opens a can of worms where kids expect rewards for stuff that they are supposed to do.
Most advice I hear/read is to use a child's "currency". It will be different with each child and change with age. Currency is usually stuff (favorite toy) that a child values or privileges (tv time) that a child values.
For example, if my DD7 isn't ready to go to school on time (with everything done - teeth brushed, cats fed, shoes on, backpack ready, etc.), then she doesn't get to play with her neighbor friends, watch tv, or play on the computer in the afternoon. She really values playing with the neighbors, so this works pretty well most of the time.
The other big piece of advice that it is important is to be consistent. Whatever you choose, it needs to be the same every time so she will know what to expect. Once you give her the rules, do not waiver or she will start to expect it.
Good luck!
