Aux

Aux is a back-office outsourcing company built around a single industry: credit unions. Founded in 1992 and based in Lakewood, Colorado, Aux operates as a CUSO (Credit Union Service Organization), providing a comprehensive suite of outsourced services that help credit unions reduce costs, manage regulatory risk, and free up internal staff for member-facing work. For any credit union looking to do more with less, Aux offers the kind of specialized support that is hard to find elsewhere in the U. S. The company's three core service areas cover the most resource-intensive back-office functions credit unions face. Accounting services are designed specifically for the credit union environment, handling daily duties, Call Report preparation, and annual budget development. Compliance services take the regulatory burden off internal teams through policy reviews, annual assessments, staff training, and marketing compliance support. The fractional CFO offering is built for credit unions that need CFO-level financial oversight but cannot justify a full-time executive hire. Clients select the monthly hours they need, getting the right level of support without the overhead of a salaried position with benefits. Aux serves credit unions across the United States, particularly those operating under pressure: short-staffed institutions, organizations facing regulatory scrutiny, and credit unions working to stay independent as merger activity continues to rise. Their clients tend to be mission-driven organizations that see outsourcing as a way to preserve resources and protect their members, not a last resort. What distinguishes Aux in the back-office BPO space is the professional background of their team. Many staff members come from decades of hands-on credit union work, so they bring direct operational knowledge to every engagement rather than generic financial services experience. Clients do not have to explain how a credit union operates. The team steps in as a genuine partner, adapting to each organization's culture and working style from day one. That depth of experience is reflected in the longevity of client relationships and the kind of confidence that comes from having lived the same compliance cycles and budget seasons their clients face each year. Credit unions interested in exploring back-office outsourcing with Aux can reach out through their website. The team is available to discuss specific pain points and help identify which combination of accounting, compliance, or fractional CFO services makes sense for each institution's size and situation.
