Accounts Receivable Assistant Jobs in California: Frequently Asked Questions
How do you become a accounts receivable assistant in California?
Most California employers expect at minimum a high school diploma plus some coursework in accounting or business, though an associate or bachelor's degree in accounting or finance gives candidates a clear advantage. No California-specific license is required for this role. Many candidates enter through community college programs at schools like De Anza, Santa Monica College, or the California State University system, then apply to entry-level billing or collections roles at healthcare systems, tech firms, or large retailers headquartered in the state.
Which companies hire accounts receivable assistants in California?
California accounts receivable assistant roles are posted by Skechers, Entisys Solutions, and NewGen Administrative Services and others right now, based on current listings on Migrate Mate as of November 2026. California's dense concentration of healthcare networks, technology companies, and large logistics and retail operations makes it one of the most active states for ongoing accounts receivable hiring.
Which California cities have the most accounts receivable assistant jobs?
Los Angeles, Irvine, and San Francisco lead California for accounts receivable assistant openings. Los Angeles drives volume through its massive healthcare, entertainment, and logistics sectors, San Francisco and San Jose reflect the Bay Area's deep roster of technology and financial services companies, and San Diego's concentration of biotech and defense contractors sustains steady demand for billing and collections support roles.
Are there remote accounts receivable assistant jobs in California?
Yes, and more than many roles, since accounts receivable work is desk-based and system-driven rather than requiring a physical presence. About 31% of accounts receivable assistant openings tied to California are remote or hybrid as of November 2026, reflecting how widely California employers have adopted flexible arrangements for finance and billing functions. Invoice processing, payment posting, and collections follow-up are the tasks most commonly performed fully remote.
How can I get hired as a accounts receivable assistant in California with little or no experience?
The most realistic entry path is landing an accounts payable clerk or general accounting assistant role first, then moving laterally into receivables once you have ERP system exposure. California community college accounting certificate programs, particularly at De Anza College, Pasadena City College, and Mt. San Antonio College, are recognized by local employers as solid preparation. Large California healthcare systems including Kaiser Permanente and Sutter Health regularly hire candidates with completed coursework and no prior experience into medical billing and patient accounts roles, treating them as trainable entry-level positions.
