• Lead weekly collections efforts:
• Send payment reminders and follow up on outstanding balances.
• Log all communications in Acumatica (ACU) and the working collections spreadsheet.
• Work with Project Managers to resolve billing disputes and verify compliance paperwork.
• Stay proactive on accounts aged 90+ days and elevate unresolved items.
• Partner with the Controller to meet AR aging and DSO goals.
• (Preferred, not required) Support WIP analysis—assessing actual % complete vs. billed % and identifying over/under billings.
• Manage lien waivers, certificates of insurance (COIs), and customer billing requirements.

• Enter vendor invoices into Acumatica with correct documentation and approval workflow.
• Process weekly check runs and electronic payments.
• Maintain vendor files and ensure timely payments to prevent service interruptions.
