The roots of the company go back to 1981 when it began life as Kennewick Computer Company and sold Atari computers. Computer sales and service remained the primary focus of the company for several years, until the need for a better point of sale system lead the company in a new direction. Not satisfied with the products available at the time, company management decided to create their own custom POS solution. When other merchants expressed interest in the software, the decision was made to form POSitive Software Company as a division that would concentrate on the development and marketing of the new point of sale product.

POSitive Retailer was commercially released in November 1993 at Fall COMDEX, then one of the largest tradeshows in the world. POSitive Retailer was DOS based and remained our flagship program until 1999.

In 1996 POSitive started to write POSitive for Windows. That software was three years in development and was released in February 1999. POSitive for Windows is now in its fourth generation and has thousands of users around the world.

In 1999 POSitive teamed with Edge Technologies, the developer of Account Wizard E-Commerce Systems, to provide a complete “round trip” e-commerce solution that seamlessly integrates the store based POS system with the web based e-commerce system. Orders taken on the web make the “round trip” by importing the web orders from the web into POSitive For Windows at the click of a button. In 2002, POSitive Software purchased all rights to Account Wizard and formed the Account Wizard Business Services division.

In 2004 POSitive introduced AveraCharge, an integrated credit card processing solution for POSitive for Windows. Merchants no longer needed to purchase seperate software or a terminal in order to process credit cards and many merchants save money thanks to AveraCharge's competitive fees.

2006 was a year of development as we readied two new products for release: POSitive Retail Manager and POSitive Commerce. POSitive Retail Manager is built around a SQL database and incorporates many new features, such as a fully customizable touch screen interface, that have been requested by our customers. POSitive Commerce is our new e-commerce service which was built using open source technology from Joomla and VirtueMart. In conjunction with POSitive for Windows or POSitive Retail Manager, POSitive Commerce is a "full round trip" e-commerce solution.

2008 brought continued improvement to POSitive Retail Manager and POSitive Commerce. The POSitive Support department introduced 24/7 support and launched the very popular daily "open training" sessions. In December, POSitive released POSitive GEM – Green Enterprise Management, a product that was developed specifically for the garden industry.

In 2009 POSitive released POSitive Retail Manager SE, a low-cost, entry-level version of the flagship POSitive Retail Manager. We will continue to develop innovative and affordable point of sale and e-commerce products for independent retailers in North America, the Caribbean and the United Kingdom.
