Employment Source

What Employment Source does

Employment Source is a privately held, independently owned human resources consulting firm headquartered in Billings, Montana, founded in 1996 and co-owned by Terry Mammenga and Sandie Mammenga. The company delivers three interconnected service lines — payroll processing, staffing and talent acquisition, and HR consulting — to employers primarily in the Northwest United States (Montana, Wyoming, North Dakota), with nationwide capability for large-scale project and event staffing programs.

Its staffing offerings span temporary placements, contract-to-hire, direct hire, and executive search across a horizontal set of industries including office/administrative, light industrial, accounting/finance, engineering, construction, IT, healthcare, sales, and skilled trades. Payroll services generate recurring fee revenue through ongoing processing, tax filing, W-2s, workers' compensation, unemployment handling, and compliance support. HR consulting provides workforce strategy, onboarding training, and employee management guidance. The firm reports no proprietary technology platform; service delivery is people-led, supported by a Wix-hosted website for job listings and applications, social media presence, and direct recruiter outreach.

The business model is fee-based professional and managed services. Staffing revenue is generated through placements and ongoing employer-of-record arrangements (handling payroll, onboarding, insurance, and taxes for placed workers); payroll processing produces recurring service fees for ongoing filings and compliance. Go-to-market is relationship-driven direct sales, with named regional customers in steel manufacturing, hospitality/campgrounds, food service, automotive retail, recycling, and trucking. The firm holds BBB A+ accreditation, is an American Staffing Association member, and its co-owner holds the SPHR certification.
