About Vanguard Ledger

Experience you can trust. Partnership you can feel.

Vanguard Ledger was built to give owners something they rarely get from bookkeeping: financial clarity paired with responsive, practical support.

Meet the founder

Built on experience. Driven by your success.

Hi, I’m Seth Simonian, founder of Vanguard Ledger. For more than 15 years, I’ve worked in finance and accounting, helping businesses organize their financial operations, improve visibility and move forward with greater confidence.

I created Vanguard Ledger around a simple belief: business owners deserve books they can trust and a bookkeeping partner who communicates clearly. The goal is not to overwhelm you with reports or accounting jargon. It is to make the financial side of the business easier to understand and easier to manage.

As a QuickBooks ProAdvisor and Xero Advisor, I support clients with the systems, monthly processes and reporting that create a stronger financial foundation.
