Job Title: Project Accounts Payable Specialist

Job Description

We are seeking a hands-on Project Accounts Payable Specialist to support a post-implementation cleanup effort following a Sage Intacct go-live. The Accounts Payable department has absorbed much of the operational impact during the implementation, particularly due to the introduction of procurement processes, purchase orders, and approval workflows that were previously managed manually or through spreadsheets. This individual will play a critical role in helping the organization work through a significant AP backlog, resolve discrepancies, improve process discipline, and stabilize day-to-day operations within Sage Intacct. The ideal candidate is highly detail-oriented, thrives in fast-paced environments, and has experience cleaning up AP functions after system implementations, process changes, or ERP upgrades.
