Client Account Services Administrative Coordinator

Who We Are

At Mahoney, we have a passion for precision by going beyond completing the necessary tasks to deliver financial peace of mind. Our Client Advisory Services team delivers real‑time insights, strengthens financial understanding, and provides tailored guidance so you can make informed decisions and drive your business forward.

Located just outside downtown St. Paul along the Mississippi River, Mahoney has been recognized multiple times by Accounting Today, the Star Tribune, and the Twin Cities Business Magazine as a top workplace. Since 1989, we've provided comprehensive audit, tax, and consulting services for individuals, businesses, real estate developers, and nonprofit organizations.

As an Administrative Coordinator, you play a critical role in supporting the efficiency, organization, and consistency of the Client Advisory Services (CAS) team. You coordinate workflows, track key deadlines, and provide proactive follow‑up to help ensure work progresses smoothly and meets firm standards. This role reports primarily to CAS team leadership and supports the CAS team, while also collaborating with other departments as needed – particularly during peak and busy seasons.

You will monitor assignments, send timely reminders, and maintain visibility into deadlines and deliverables across engagements. By supporting adherence to standardized processes, checklists, and documentation requirements, you help the team maintain high‑quality, consistent output.

This role also includes following up on missing information, incomplete steps, or process deviations in a professional and collaborative manner. You will identify recurring delays or gaps, elevate concerns when appropriate, and contribute to continuous improvements in team workflows.

In addition, you provide administrative and client service support by assisting with proposals, engagement letters, and onboarding documentation. You support billing processes by gathering information, tracking billable items, preparing invoices, and helping ensure timely invoices and collections.

You will assist with year‑end processes, including 1099 tracking and preparation, and organize vendor documentation while monitoring key deadlines. Maintaining accurate client files, correspondence, and workflow documentation in alignment with firm standards is an essential part of the role.

This is an onsite, part‑time position requiring approximately 25-30 hours per week spread across five days.
