Eide Bailly
Accounting firm
Eide Bailly Advisory LLC and Eide Bailly LLP (each doing business under the trade name Eide Bailly) are American mid-tier advisory and accounting firms based in Minneapolis, Minnesota. They primarily provide accounting, advisory, tax, and assurance services.
The current accounting partnership traces its roots back to 1917 and was formally founded in 1998 by a merger of two namesake regional accounting firms: Eide Helmeke & Co. and Charles Bailly & Co. In 2026, to accommodate a $1.8 billion equity investment by Reverence Capital Partners, the firm's non-attest operations were reorganized into an advisory entity. As of 2026, that advisory entity employs almost all of the approximately 3,500 professionals across 50 offices in 20 states.
The firm is recognized as a top CPA firm by trade publications based on its revenue in the United States, with significant inorganic growth occurring after 2017.

Why this record matters
The phrase “accounting firm” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 23, 2026. The linked authority identifier is Q5348780. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1917, 1998, 2026 and 2017.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
