Accessing customers, customers accessing you

In almost every business sector, the method of access to information on suppliers has changed. The web is the cornerstone of business development in nearly every sector, in both consumer and business to business.  In most consumer sectors, access is also required on mobile and tablet devices with different screen resolutions.  This is not yet mainstream in business to business sectors but this is likely to happen as the younger business buyer will see mobile as the obvious and only way to access information.  This has implications in offline and online communication formats.  The key question is – do you know the norm in your sector?  Or, do you want to be ahead of the pack?
