Accounting & Office Support in Milwaukee, Wisconsin at Sigma Commercial LLC

About Us

Sigma Commercial is a Milwaukee-based holding company. We own and run several operating businesses across construction, property maintenance, and property management, including LaBonte Construction (luxury residential remodeling), Property Prep (commercial maintenance and janitorial), and Vandelay Group (property management on Milwaukee's east side). This role sits at the holdco level and supports all of them.

The Role

We're a lean operation, so this job is not a narrow lane. You'll handle the core accounting work across our companies, and when things come up outside that lane, you'll help with them too. If you need every day to look identical to the last, this isn't the right fit. If you like knowing your work actually matters to a small team and don't mind switching gears, it could be.

What You'll Do
Process accounts payable and receivable across multiple entities
Support payroll processing
Track expenses by property and by business unit, and flag anything that looks off
Assist with budgeting and light financial reporting for ownership
Help our controller coordinate with our outside CPA at tax time
Pitch in on general office tasks: vendor communication, filing, scheduling, ordering supplies, answering phones, and whatever else keeps a small office running
What We're Looking For

Required:

Solid grounding in general accounting or bookkeeping (education, certification, or hands-on experience all count)
Comfort with accounting software and general office technology; you should be able to pick up new systems without hand-holding
Reliability. We need someone who shows up, follows through, and can be trusted with financial details without close supervision
A problem-solver's instinct: when something doesn't reconcile or doesn't make sense, you dig into it rather than passing it along

Preferred, not required:

Background in construction, property management, or real estate accounting
Experience working across multiple entities or business units
Familiarity with QuickBooks or similar platforms
