The Bill icon is primarily comprised of a rectangle that looks like a piece of computer paper, so the width is shorter than the length. Near the top is a straight horizontal line, which gives the impression of a title. In the bottom half of the rectangle are three horizontal lines, and each of these lines is broken to create a small space near the right end to make it look like you would see a description, space, price.
