We chose One Abacus Advisory to provide support to our accounting team while we recruited after our Finance Director departed our organization. Lorin met with me to efficiently assess how best to help our organization. Marjorie, from One Abacus Advisory, was able to step in as our interim Director seamlessly with minimal support, allowing our team to focus on our mission. One Abacus Advisory’s deep expertise in nonprofit accounting and NetSuite was a great help to us and took the pressure off as we looked to fill a critical role on our team. We were able to maintain our month-end close with no disruptions thanks to their help!

Beyond their obvious knowledge, the One Abacus Advisory team was incredibly professional and a genuine pleasure to work with. Marjorie’s calm confidence and friendly demeanor provided us with stability during our transition. She felt more like an internal member of our team than an outside consultant. I highly recommend One Abacus Advisory to any nonprofit organization seeking high-level financial expertise.

One Abacus has been an exceptional partner to our organization during a crisis period. They quickly organized and brought together an extraordinary team that seamlessly supported everything from day-to-day accounting operations to complex audit preparation. Their expertise, efficiency, and calm command of the work immediately gave our staff and board confidence.

What impressed me most was their ability to truly understand the nuances of our organization and tailor their support accordingly. They were consistently responsive, even when faced with urgent or last-minute requests, and approached every challenge with professionalism and thoughtful problem-solving.

Beyond their technical excellence, the One Abacus team communicates clearly, works collaboratively, and operates with the highest level of integrity. Their support was comprehensive and reliable, and they were genuinely a pleasure to work with throughout the entire process.

I highly recommend One Abacus without hesitation to any organization seeking a trusted and experienced financial partner who combines deep expertise with outstanding client service.

Lorin and the team she assembled have been exceptional in their expertise, professionalism, and adaptability. They conducted a comprehensive accounting assessment that gave us clarity on our financial operations and identified key areas for improvement.

Their optimization of our NetSuite environment has significantly enhanced our reporting capabilities and operational efficiency. In parallel, they’ve supported our Executive Team in becoming more financially literate during a critical leadership transition to a new CFO and Controller. All of this has been accomplished while ensuring continuity with our lean internal finance team. We couldn’t be more grateful for their partnership.

We appreciate many things about One Abacus, but the thing that stands out most is their team’s investment in our success. They have gone above and beyond to deeply understand our organization and our financial structure. One Abacus’ outside viewpoint and collaboration have allowed us to create and implement a more effective budgeting and cash forecasting system that will give us a timely, concise picture of our financial performance throughout the fiscal year.

One Abacus has been an incredible partner during a critical time for our team. They quickly mobilized a talented group of professionals who handled everything from day-to-day accounting to audit prep with expertise and ease. They took the time to understand our unique needs and were always responsive—even for last-minute requests.
What truly sets them apart is their professionalism, clear communication, and problem-solving approach. Their support was comprehensive, and they were a pleasure to work with every step of the way. We highly recommend them.

One Abacus stepped in when our organization was overwhelmed, understaffed, and faced with a major restructuring. Their expertise was instrumental as we rebuilt our financial operations from the ground up. We are grateful for the clear, steady guidance that helped set us up for success.
