Whenever i send out an invoice to someone it will classify it as "Sales".

This is not always correct, sometimes its sales, sometimes i would like it classified as "management income" Other times its not income at all im being reimbursed for a previous expense, i would to classify it under that category.

But its automatically putting any invoice i send out into the Sales category and i dont know how to change it or how to change it after the fact.

Any help would be greatly appreciated.
