Manufacturers are expected to continue contracting out more of their sales functions to independent sales agencies in an attempt to control their costs. This should mean more job opportunities for sales engineers in independent agencies and for self-employed independent sales engineers.

Employment opportunities and earnings may fluctuate from year to year because sales are affected by changing economic conditions, legislative issues, and consumer preferences. Prospects will be best for those with the appropriate knowledge or technical expertise, as well as the personal traits necessary for successful sales work.
