Founder
Meet Jason Koscinski.
Intuit Accountant Council Member, 2014–2016
Hi, I'm Jason — a professional bookkeeper since 2008 and the founder of JRK Financial, established in 2013.
For over a decade, JRK Financial has been dedicated to providing reliable bookkeeping to small businesses like yours. Our team focuses on keeping bank and credit card accounts reconciled so your Profit and Loss report is both accurate and easy to understand.

Personal, meticulous, and dependable.
QuickBooks or something else?
If your business needs help with bank reconciliations or keeping your QuickBooks or Manager file organized and accurate, we could be the perfect fit.
Straightforward pricing
Pricing is typically based on the volume of bank statements we handle each month. Weekly-service clients get premium activity in their file; monthly clients get a budget-friendly cadence using our own software.

Payroll
Payroll services for small businesses in Kalamazoo, Michigan
Payroll is one of the first places small-business books go sideways: one lump withdrawal in the bank feed, with no breakdown of wages, taxes, and employer costs. JRK Financial provides payroll support coordinated with your bookkeeping, so every payroll run is recorded clearly and your payroll reports tie to your books. We're based in Kalamazoo and work with businesses across the Kalamazoo area.
We run payroll for clients using Gusto, file quarterly payroll tax returns, and prepare year-end W-2s and 1099s.
Recorded in detail
Wages, payroll taxes, and employer liabilities are broken out in your books, not lumped into a single withdrawal, so your reports and payroll filings agree.
Coordinated with your bookkeeping
Payroll is reconciled alongside your bank and credit card accounts each month, so your Profit and Loss reflects what payroll really costs.

JRK Financial was a huge help in getting our LLC set up. They handled the paperwork efficiently and made the whole process much easier than trying to figure it all out on our own. Professional, knowledgeable, and easy to work with—highly recommend!
Jason and his team are FANTASATIC! We switched over to their business in Q4 2025, and it has been one of the best decisions we have made. We didn't know what we had been missing until we started working with Jason, he has really elevated our bookkeeping.
Jason and the JRK Financial team are extremely professional and responsive to our organization's needs. They have a rapid turnaround on reports that are needed for board meetings or grants. I highly recommend. Founder Neena Marion with Kalamazoo Refugee Resource Collaborative.

Great Prices Great service and Great Accoubtants!!!
When I first opened my business I had a accountant that wasnt much help with explaining expences and profit and loss and she didnt keep up with my bookkeeping, I was referred to JRK financial and he took care of my problems and sorted out all my expences so I could make a quarterly tax payment. Then he referred me to Brad who has been a great tax guy for me and my husband. Both prices are very reasonable and hes super helpful and quick to respond when I have any questions! I highly recommend JRK financial for any of your small business accounting needs!
Very professional and efficient.
