Salesheets are handy when you have new products to offer, or product lines going on special and you would like your sales representatives to market these items to your customers. A company might have monthly specials which can be printed in salesheet format and posted to customers with their statements at the end of every month. Salesheets are usually a bit bigger (A4 size) and more involved than flyers, and usually contains pricing, expiry dates and individual product pictures.
