Bookkeeping & Financial Guidance · Omaha & Bennington, NE

Clean books.
Clear decisions.

I fix messy books, find mistakes others miss, and give business owners clear, practical financial guidance so they can make confident decisions.

PMK Accounting provides tax-informed monthly bookkeeping, detailed cleanup, and practical financial guidance for growing businesses in Omaha, Bennington, and beyond.

Work directly with an experienced accountant who looks beyond whether the accounts reconcile—reviewing your numbers for errors, unusual activity, cash-flow concerns, and trends that deserve your attention.

Does this sound familiar?

You didn't start a business to spend nights wondering if QuickBooks is right.

"Money's coming in, but I don't know where it's going."

"My reports never seem to match what's actually happening."

"I'm behind, embarrassed, and not sure where to start."

"My bookkeeper records things, but no one helps me understand them."

How PMK helps

Accurate bookkeeping is the starting point — not the finish line.

You get someone who keeps the books clean, spots problems, explains what the numbers mean, and helps you think ahead—with tax-informed experience behind the work.

"Katie has taken a huge amount of stress off our family's plate."

"She was fast, professional, and super easy to work with."

Real problems I've uncovered

This is why "the books look fine" isn't enough.

$900K

Potentially duplicated expenses identified

A detailed review found bills and related checks recorded separately over several years, materially affecting the financial statements.

$700K

Potentially duplicated income identified

Deposits had been entered manually and also added through the bank feed, overstating reported income.

$350K

Reporting difference investigated

Unlinked credit-card activity and unreconciled payments created a significant gap between reported and reviewed profit.

Examples are based on prior cleanup engagements. Details are generalized to protect client privacy, and results vary by business and condition of the records.
