I'm Katie Onken, owner of PMK Accounting. I make sure your numbers tell the truth — not just reconcile. With 15 years of accounting experience, I clean up complicated books, spot issues early, and help business owners understand what their numbers actually mean so they can make confident decisions.

I'm Katie Onken, founder of PMK Accounting, LLC. Based in Bennington, Nebraska, I provide bookkeeping and financial guidance to growing businesses throughout Omaha, Greater Nebraska, and remotely.

With more than 15 years of accounting experience, I help business owners clean up financial problems, build reliable systems, and understand what their numbers are telling them. I'm a QuickBooks Online Advanced Certified ProAdvisor with experience in corporate accounting, financial leadership, and tax preparation.

"I don't want to hand you a report and leave you to figure it out."

I review your numbers for inconsistencies, unusual changes, duplicated activity, incorrect classifications, cash-flow concerns, and trends that deserve attention. When something does not look right, I ask questions — and when the reports are ready, I help you understand what they mean for the business.

I work with law firms, construction companies, real-estate businesses, nonprofits, professional-service companies, and other owner-led businesses using QuickBooks Online.

My tax-preparation background also helps me recognize bookkeeping issues that may matter at tax time before they become year-end surprises. I keep your records organized, help you plan throughout the year, and coordinate with your CPA or tax preparer when a decision requires tax advice.

Why this work

I understand what it takes to run a business.

I grew up watching the long hours and personal sacrifices involved in building something of your own. I live it now, too. My husband owns a financial-planning business, we have three young kids, and I run PMK Accounting.

I know how valuable it is to have help you can trust — someone who will not judge the mess, who speaks plainly, and who gets the numbers right. You focus on building the business. I'll help make sure the financial side supports where you want to go.
