Landing customers isn't typically big news – it is, after all, the goal for most businesses – but Lending Solutions' April 10 announcement that it added eight more credit unions to its customer list last quarter is a notable reflection of how the lending boom's effects are spreading to call centers.

Credit union loan balances grew at a 10.9% seasonally adjusted, annualized rate in February, according to the latest data from CUNA Mutual Group, and they grew by 0.22% in just that month – double the 0.11% pace for the same month last year. Notably, February is historically the weakest month for loan growth. Loan growth is so robust, in fact, that CUNA Mutual compared the current upswing to the credit boom of 2004 and said it expects loan balances to grow over 10% in 2015 and 2016.

With all that new lending comes more underwriting, processing, question answering, collections and other activities that require more people and more expense for credit unions. And that, in turn, means big business for call-center outsourcing firms such as Lending Solutions.
