Part-Time Nonprofit Bookkeeper

Position Overview

FSI seeks an experienced Part-Time Nonprofit Bookkeeper to support the Finance Department. Reporting to the Director of Finance & HR, this non-exempt, fully remote role performs assigned bookkeeping and accounting support functions in QuickBooks Online (QBO) and supports accurate month-end reporting.

FSI manages approximately $40M in assets and processes $24–30M annually in grants, expenses, and programmatic investments, including donated property, in-kind contributions, stock gifts, and real assets. This role provides critical execution-level support to ensure the accuracy, integrity, and audit-readiness of those records.

Important note on system transition: FSI anticipates migrating to a new accounting system in the near future. This role will maintain continuity and data integrity in QBO during the transition period, then perform bookkeeping functions within the new system following implementation. Candidates should be comfortable with change, capable of adapting workflows, and willing to contribute actively to a successful migration. This is a meaningful added responsibility that is reflected in the compensation range.

Schedule & Flexibility

This is a part-time role offering 10–20 hours per week with flexible scheduling coordinated within Eastern Time business hours. The position is well-suited for professionals who can commit to a consistent, predictable schedule and maintain reliable availability during agreed-upon hours—whether that’s structured around personal commitments, a second role, or other priorities. Reliability and consistency are as important as flexibility.
