So much of business is conducted electronically now, but there is still a need for a high-quality glossy brochure to support your sales and marketing initiatives.  If you sell multiple services/products, you may like to consider a folder that you can insert specific product sheets into according to the exact needs of the customer instead of a ‘traditional’ booklet.  As with all other marketing collateral, ensure that the quality of your design and copy reflects what you are selling – if your brochure looks cheap, I’m afraid that is what the recipient will perceive of you and the service/product you supply.
