About Our Firm

Avonis is a value-driven practice that  offers Tax, Accounting & Bookkeeping services to small and mid-size CPA firms. We support a client base that range from single member firms to multi-partner practices. We are committed to a seamless integration of our staff to your firm.

Avonis was founded in 2012 with the intention to support the tax practice of our founder and CEO Kash, along with his partners. Utilizing the staff at Avonis created great cost stabilization and office efficiency for the practice.

How We Began

Leadership  realized that any small to mid size CPA firm would benefit from the value created from a partnership with Avonis . We decided to develop and grow the Avonis staff with the intention of supporting other CPA firms.

Laying The Foundation

In the summer of 2012 Avonis signed its first engagement letter with another CPA firm.  It provided the firm with staff to handle both accounting and tax work.  The CPA firm was able to realize a substantial cost savings and also a more efficient office environment.  They continue to remain Avonis’s longest tenured client.

Our First Partners

As we continued to grow, Avonis gradually took on clients to partner with.  This was done strategically to make sure our staff had enough time to learn and develop organically.  Our patience has paid off as we are currently positioned to support the staffing demands of any CPA firm.

Labor of Love

Currently Avonis is one of the fastest growing firms in the Midwest.  We have a team of accounting professionals that are technically prepared to support the needs any CPA practice has.  Avonis is ready to partner with you to create the value and efficiency you deserve.
