Founded by Scott Smith and operated by Mark Hackmann, UDTH Accounting was built as a response to the needs of  the micro and small business communities. Scott and Mark met while at Law School in San Diego, California we began working together writing International Tax Law and International Company Law publications for a major professional publication. 

In short, UDTH helps small businesses succeed in a tough regulatory and financial environment. Scott, a New York native and Mark, born and raised in St. Louis are individuals uniquely suited to navigate this environment given their positioning and  emotional desire to create a level playing field for all businesses regardless of size and resources.

Security is our highest priority. We pride ourselves in having developed a reliable and private system that is supported by the major software providers; Microsoft, QuickBooks and LogMeIn. All of your files are stored directly on our private server. No cloud servers means no exposure to cloud security risks.

Bookkeepers record, store and retrieve financial transactions for a company or non-profit organization. Bookkeepers much have detailed knowledge of debits and credits with a basic understanding of financial accounting. Including the balance sheet and income statement. Bookkeepers record the financial effects of a transaction.

Bookkeepers are not tax preparers. Accountants are required to interpret the transactions as accurate and agreeable with general accounting principles.

Proper bookkeeping will reduce the costs of an accountant and in some cases, allow the business owner to file taxes directly from the bookkeeping software.
