Nightowl bookkeeping clients

We've grown with:

Our clients have grown significantly alongside NightOwl over the years. Although we're a remote service, we're proud of our roots in Chicago, IL and the impact we've had on local small businesses and the communities they support.
Knowing we're playing a small role in impactful organizations makes working with you that much more engaging.

Back of the Yards Coffeehouse

Back of the Yards is a neighborhood in Chicago's south side that has a special place in our hearts. My consulting practice started with this coffeehouse as they were struggling to get their financials in order. Since then, BOTY Cofee has expanded to a roastery warehouse and has earned the interest of investors and grants across the nation. Jesse and Mayra were always a pleasure to work with and we're excited to see them expand.

Illinois Hispanic Chamber of Commerce

The Illinois Hispanic Chamber of Commerce was in dire need of financial reconciliation and organization. Three years of mismanaged accounting almost led to disaster, but with our expertise, IHCC is back on track and better than ever. We've written and hosted 40+ small business webinars during COVID-19 that helped SMBs get federal and state assistance to continue running their businesses, as well as helped 100+ small businesses with 1-on-1 financial consulting, at absolutely no cost.

Burnham Park Yacht Club

Burnham Park Yacht Club is a beautiful membership club on Chicago's lakeshore, with over a century of history and culture that you can feel as soon as you walk through the doors. We helped BPYC migrate their accounting software to QuickBooks, managed their POS, payroll, and membership software. We assisted in strategic operations with their membership structure. BPYC is continuing their legacy and growing more and more everyday.

Rios & Co. Accounting, Inc.

Rios & Co. was where my accounting expertise and love for small business consulting grew. Based in the heart of Chicago, in our beloved Pilsen neighborhood, Rios & Co. was a Latino-owned and led accounting firm that specialized in helping Latino-owned businesses grow with bookkeeping, payroll, and tax preparation. I personally assisted 100+ small businesses with their bookkeeping, payroll, and financial advisory across many industries like food+beverage, construction, and professional services.
