Our Socials
One may ask, “What is a bookkeeper?” Understanding what a bookkeeper is starts with trust, accuracy, and expertise. A bookkeeper is so much more than simply tracking expenses, a great one can transform your entire business through the implementation of strategic business systems. Core Columbia is an expert bookkeeping firm and QuickBooks online advisory that provides monthly bookkeeping for small business owners to help you gain confidence in your financial systems. We specialize in high quality personal tailored service that allows our customers to feel valued.
Founded in 2020 by Ashley Custer, an expert bookkeeper and QuickBooks Pro Advisor, Core Columbia Financial was built with a clear mission: to deliver expert level bookkeeping services that are both accessible and tailored to the real needs of growing businesses.
Many small business owners struggle to balance the cost of bookkeeping, with the quality of service they receive. When trying to understand what a bookkeeper is – and what level of support they truly need, business owners are often forced to choose between affordable solutions that lack quality and premium services that come with unnecessary overhead. Core Columbia’s mission is to bridge that gap by offering reliable, professional monthly bookkeeping at reasonable rates, so you can focus on growth while feeling at ease.
