For businesses that need working capital on a short-term or
cyclical basis, the SBA has a collection of revolving and
nonrevolving lines of credit called Caplines. A revolving loan is
similar to a credit card, where you carry a balance that goes up or
down, depending on payments and amounts borrowed. With nonrevolving
lines of credit, you borrow a flat amount and pay it off over a set
period of time.
