In addition to improving customer satisfaction and the ability for tellers to upsell customers, the Getronics system also integrates well with Commerce Bank's existing online banking software, Corillian Voyager. So well, in fact, that they share a common back end, a similar look-and-feel, and nearly all the same features.

The Globalfs software also allows Commerce Bank to collect more information on teller performance.

"We had good information on what is going on at the call center or the Web. We didn't have it for our tellers," he said. "We also now get a lot more reporting on what is going with our tellers. Now we know which types of transactions take a long time. We can also do more intelligent staffing. And we can cut the time for tellers to do their end-of-day balances by 50 percent."

Kim expects to make back his investment in Getronics in three to five years.
