About A to Z Bookkeeping and Tax

A to Z Bookkeeping and Tax is led by Teresa Montgomery, who brings more than 30 years of private-sector experience and a QuickBooks ProAdvisor certification to every client relationship. As a locally rooted business serving the Johnson City area, A to Z focuses on giving business owners a clear, current picture of their finances rather than a stack of unresolved paperwork. Every engagement begins with a free consultation, so you can talk through your situation and understand your options before committing to anything. Both virtual and in-person appointments are available, which means you can get organized books without rearranging your entire workday around a single office visit. Whether your records need a full clean-up or steady monthly maintenance, the goal is the same: books you can trust and use to make decisions.

A to Z Bookkeeping and Tax was founded to give local individuals and small business owners direct access to personal bookkeeping and tax support, rather than being passed between departments at a larger firm. That gap was especially felt by owners who needed a steady point of contact who understood both their numbers and their day-to-day operations. Since then, the practice has grown its service area to cover Johnson City, Erwin, Greenville, Rogersville TN and surrounding communities within approximately 15 miles, along with Kingsport, Bristol TN/VA, and Abingdon VA. That growth has followed word of mouth from clients who wanted the same personal approach for their own bookkeeping and tax needs.

After more than 30 years working in bookkeeping and accounting in the private sector, Teresa saw how much value that experience could bring to individuals and small business owners who rarely had access to it directly. She wanted to take what she had learned managing complex financial operations and put it to work for people in her own community. That meant building a practice centered on relationships rather than impersonal, once-a-year processing. Teresa's approach is to know each client's business well enough to catch issues early and offer guidance that actually fits their situation. She built A to Z Bookkeeping and Tax to be the kind of firm she always wished more of her own clients had access to.
