ABOUT AFFINITY STRATEGIES

Affinity Strategies is a full-service association management company (AMC) dedicated to helping professional and trade associations achieve their missions with excellence and efficiency. We provide strategic leadership, operational support, and comprehensive financial management to a portfolio of nonprofit member organizations. Our team is collaborative, mission-driven, and committed to delivering outstanding service to the associations we serve.

POSITION SUMMARY

Affinity Strategies is seeking an experienced Staff Bookkeeper to serve as the primary financial officer for our internal operations and the associations we manage. This is a high-impact, full-cycle accounting role responsible for all day-to-day financial operations across a portfolio of nonprofit clients — including accounts payable, accounts receivable, general ledger management, bank reconciliations, financial statement preparation, budget support, and compliance coordination.

This person will own the financial function end-to-end for multiple association clients simultaneously. The ideal candidate is a self-directed accounting professional with deep nonprofit experience who is comfortable managing complex, multi-entity environments and serving as the trusted financial resource for both internal staff and client volunteers. Experience with nonprofit fund accounting, Bill.com, and QuickBooks Online is essential.

Note: Tax return preparation (Form 990), formal audits, and tax filings are handled by outside specialists. All other accounting functions are the responsibility of this role.
