Tonnesen Accounting Services provides Quality of Earnings reports, sell-side preparation, bookkeeping, and fractional CFO support for small and mid-sized businesses nationwide.
The financials a seller hands over have not been independently checked. Our Quality of Earnings work tests them against bank statements and filed returns, so you know what the business earns before you are contractually committed.
Quality of Earnings analysis, sell-side preparation, bookkeeping and fractional CFO support, for business buyers, owners, and the lenders who finance their deals.

We rebuild the company's earnings from source documents, so you can see what the business really makes and negotiate from a number you can defend.

Get your financials in order before going to market. We help business owners correct errors and organize documentation before a buyer's QoE review finds them first.

We see what messy books do to a deal, because reading them is most of what we do. This is that same standard applied monthly, instead of once under pressure.

Most businesses this size need CFO-level work a few days a month, not a salary. Forecasting, reporting, and the financial side of the bigger decisions, on that basis.

Josh Tonnesen is a CPA who spent his career in Fortune 500 corporate accounting before starting the firm. The idea was simple: buyers of small businesses were getting a lighter version of the diligence a large company would insist on, mostly because nobody wanted the work at this deal size. We took the work. Over 600 engagements later, the firm also handles sell-side preparation, bookkeeping and fractional CFO support.
