How Cloud Companies Are Killing Checks

The amazing quote to me by Celent analyst Gareth Lodge, “The U.S. is 20 to 30 years behind other countries in moving away from paper” . I have had a number of clients over the years have their banking information stolen from a paper check.  Due to this, many of these businesses have had to keep two and three separate bank accounts.  One for payroll, one for operations and one for savings.   The security, internal controls, and time savings brought on by using digital payment software and services really should have all small businesses thinking.  Many small businesses already mandate that new employees receive direct deposits so I believe it would be a logical progression to pay their vendors electronically too.
