About Us

Located in Atlanta, GA, W9manager’s mission is to help companies comply with increasingly complex information reporting regulations.  Specifically, the process of requesting a W-9 form from every vendor and then determining what vendor payments have to be reported to the IRS on a 1099 form.  We are driven by a passion to automate the entire W-9/1099 process from vendor on-boarding through 1099 processing.  And we provide an affordable solution that can be used by all companies, not just the Fortune 500.

John Croyle, MBA, CPA

Founder, Rockwater Technology

Prior to founding Rockwater, John was a controller for several companies including Enterprise Rent-A-Car, eFolder and Urban Expositions. Enterprise, with its ownership of Alamo/National is a $21 billion international auto rental company. Both eFolder and Urban are private equity backed companies, with eFolder focused on technology and Urban on managing tradeshows.

While working each of these roles, John became increasingly frustrated with the manual process of requesting W-9s, managing and storing them, and determining if vendor payments were reportable.  In addition, 1099 forms still had to be mailed to all vendors in a day when everything is delivered electronically.   Pulling on a strong technical and tax background, W9manager was born.
