A little about us….

About the Owner

Welcome! I’m Sarah Castle, Owner of Castle Accounting Services, LLC. I am a dedicated accountant with 20 years of experience helping businesses achieve financial clarity and stability. At Castle Accounting Services LLC, I specialize in bringing order to messy books and establishing solid financial systems for growth.
While my expertise is rooted in supporting Contracting Companies both Prime and Sub (Construction, Plumbing, Electrical, etc) Transportation Companies and Manufacturing Companies, I also provide valuable solutions for small and medium businesses with specialized needs such as forensic accounting support, process improvement, and internal control optimization.

Our Expertise

Over the years, I’ve built a reputation for uncovering opportunities and solving complex financial challenges. We have recovered $300,000 in underbilled revenue for a business by identifying gaps in billing practices and implementing clear, efficient processes. In another instance, we uncovered over $1 million in credit card theft, working to strengthen internal controls and safeguard the organization’s assets.

These experiences and more allow us to handle a wide range of financial issues including day-to-day accounting, complex Job Costing solutions and high-stakes investigations.
