About

At TWI, we are pioneers in the way bills get paid. In fact, we’ve taken the various, often complex and costly facets of billing and payments and created a one-stop solution:Summation360™ It has revolutionized the way our clients — primarily utility companies — track customer consumption, invoice, send out notifications, process payments and more.

Summation360™ is designed to bring billing and payment together into a single, highly cost-effective process that delivers savings by permanently eliminating the cost and burden of manual activities. Quite simply, we have found that agencies are frequently paying more than they need to be, without reaching the customer adoption goals they are seeking. With Summation360, your agency will have a proven vision and path leading to “paper-free” billing and automated payment handling.

TWI is the leading provider of billing, payment, and communication solutions for billing organizations in North America. We have over 500 customer implementations across the U.S. and Canada.
