• Coordinate troubleshooting of complex system issues and elevate technical matters to external partners when appropriate.

Support, Training & Adoption

• Establish and maintain a scalable Finance systems support model, including a network of Finance and business Acumatica SMEs to provide first‑line support for routine business process and system questions.
• Provide escalation support for complex issues while ensuring recurring questions are addressed through training, process changes, or system improvements.
• Develop and maintain SOPs, training materials, process documentation, and system knowledge resources.
• Lead training for new users, new functionality, process changes, acquisitions, and greenfield launches.

Acquisitions & Greenfield Growth

• Assess target companies' finance systems and data during diligence, and develop pre‑close integration plans.
• Support acquisitions and greenfield launches by leading the setup, integration, and deployment of Acumatica and related Finance systems, in partnership with Finance, IT, and brand support teams.
• Lead Acumatica setup, configuration, data migration, testing, cutover, and user readiness associated with new businesses and locations.
• Develop repeatable Finance systems implementation standards, templates, and processes to support the company’s acquisition and organic growth strategy.

Integrations, Controls & Reporting

• Oversee Finance‑related integrations between Acumatica and connected platforms, partnering with IT and external vendors on monitoring, exception management, ownership, and escalation protocols.
• Support Finance technology solutions including payment platforms, banking integrations, expense and AP tools, operational system interfaces, and reporting solutions.
