Although it is critical for a new company to have a great product, that great product has to be packaged in an appealing way before anyone will buy it! I recently have had members of a management team express that reviewing brochure copy is " at a low level of detail" - nothing could be further from the truth!
The copy that is placed on your website and in your product brochures helps to create your company and product image in the marketplace. Writing this copy as an after thought is analogous to putting on fine makeup and jewelry, then going to dinner in rags!
Be sure to think through the wording you use - and make your product sound as appealing as possible. Capture the essence through a verbal picture of what makes your product - or company - unique in the marketplace.
Dress your product well, and your market will respond accordingly.
