About Us
Sigma Commercial LLC is a Milwaukee-based holding company providing shared back-office support to a group of operating businesses spanning residential remodeling, commercial maintenance, and residential property management.

The Role
We're looking for an Accounts Payable Specialist to own invoice-to-payment for our group of companies. You'll process a high volume of vendor invoices across multiple entities and cost centers, keep vendors paid on time, and keep our books clean enough that month-end close doesn't turn into a scramble.

Match invoices to purchase orders and receipts; flag and resolve discrepancies
Prepare and execute payment runs (checks, ACH) on schedule
Maintain vendor files, including W-9 collection and 1099 tracking
Reconcile vendor statements and respond to vendor payment inquiries
Support month-end close with AP accruals and account reconciliations
Work across multiple accounting/property management software platforms as needed by entity

What You'll Bring
Prior accounts payable experience, ideally across multiple entities, properties, or cost centers
Comfortable in QuickBooks or similar accounting software; able to pick up additional platforms as needed
High attention to detail and strong organizational skills, especially when managing volume across several entities at once
Clear, professional communication for vendor follow-up
Ability to work independently and keep pace during busy periods (month-end, high invoice volume)
