Role Description The Sr. Accounting Clerk is a temporary-to-permanent, full-time, on-site role based in Picayune, Mississippi. This position combines foundational clerical accounting responsibilities with enterprise-level proficiency in Microsoft Dynamics AX and Dynamics 365 Finance & Operations (D365 F&O). Because D365 F&O is a highly integrated, multi-entity system, the successful candidate must understand not only how to enter and process transactions, but also how those transactions flow through subledgers, affect the general ledger, support department or job costing, and influence broader business operations. The role is responsible for high-volume accounts payable, accounts receivable, cash and bank management, journal processing, invoice matching, reconciliations, discrepancy resolution, and accurate financial recordkeeping. The Sr. Accounting Clerk also supports month-end and year-end close activities, collaborates with internal departments and external vendors or customers, maintains digital documentation within the ERP system, and contributes to reporting and process improvements.
