Senior AP Specialist

Senior AP Specialist, Shared Services
Keystone Access Partners | Chicago, IL (remote, initially)

About Us
Keystone Access Partners (KAP) is a Shore Capital Partners-backed platform of commercial door, gate, and access control service companies, including Dillard Door & Security and Ritchie Group. We're growing through acquisition and building the corporate infrastructure to match.

The Role
We're centralizing accounts payable for one of our operating companies into a single shared services function. That means there's no legacy process to inherit and no "that's how we've always done it." You'll process invoices, yes. You'll also help decide how invoices get processed: what gets automated, what gets eliminated, and what a best-in-class AP function looks like at a company that plans to keep acquiring.

This is a good fit for someone who's done AP long enough to know where the pain is and would like to be the person who fixes it.

What You'll Do

• Own day-to-day AP across multiple entities: invoice intake, coding, approvals, 2- and 3-way matching, payment runs, and vendor inquiries
• Help migrate AP from legacy systems into the new ERP, including vendor master cleanup and consolidation across entities
• Evaluate, implement, and tune AP automation: OCR/invoice capture, approval workflows, ePayables and virtual card programs, and AI tools where they make sense
• Document processes as they're built so the next acquisition plugs in faster than the last one
• Onboard newly acquired companies onto the centralized AP process
• Support month-end close with accruals, AP reconciliations, and aging analysis
• Manage 1099 compliance, vendor W-9s, and sales/use tax on purchases
• Flag inefficiencies and propose fixes, then help execute them
• Travel to operating locations (10-20% normally, but could be higher during integrations and acquisitions)

What You Bring

• 5 years of full-cycle AP experience, ideally multi-entity
• Hands-on experience with at least one ERP; Acumatica a plus
• Comfort with Excel beyond the basics (lookups, pivots, cleaning ugly data)
• Genuine interest in automation and technology, with some evidence you've acted on it (a workflow you built, a tool you rolled out, a manual process you killed)
• Ability to work with field and operations teams who do not think about invoices as much as you do
• Detail-oriented without being slow; comfortable with some ambiguity while things get built
• Experience in field services, construction or a PE-backed environment is a plus

Why This Role

• Build a function from scratch instead of maintaining someone else's
• Direct exposure to finance leadership and to the M&A integration process
• A growing platform where the AP function, and the people in it, scale with the business
• Competitive pay and benefits
