Our story

One Source Bookkeeping was founded by Kristina Weaver and John Morgan, who between them bring more than 35 years of bookkeeping and financial systems experience. Both are Intuit Certified Gold QuickBooks ProAdvisors.

We started the firm after years of the same conversation. A business owner would come to us with books in disarray, having already bought two or three pieces of software that were supposed to solve it. What they needed wasn't another app. They needed someone dependable to steward the books, and someone willing to explain the numbers in language that actually meant something.

That's the whole business. We do the work carefully, we do it on time, and we tell you the truth about what we find — including when the truth is inconvenient.

We work with small businesses across Frisco and the DFW metroplex, and with clients nationwide who'd rather have a named person on their books than a support queue.
