Outsourcing is a common practice for businesses today in areas including staffing, corporate services and recruitment. A corporate travel agency may be used to handle travel arrangements for company employees.

These non-core expenses can consume a significant part of a company’s budget. Experienced ERA consultants analyze supplier costs in expense categories like these to help clients recover cash flow.
