Accounts Payable Specialist III
Marietta, GA | Fully Onsite | $27.00/hour | Contract
Before You ApplyThis is an experienced-level Accounts Payable role.
Please consider the following before applying:
Do you have recent experience independently managing complex Accounts Payable issues, including invoice, PO, payment, or vendor discrepancies?

Our client is seeking an experienced Accounts Payable Specialist III for a fully onsite accounting team in Marietta.
This position is intended for someone who already has a strong AP foundation and can take ownership of more complex transactions and issues with limited direction. The Specialist III will spend much of the day working between the financial system, Excel, invoices, purchase orders, vendor records, and supporting documentation.
This is a good fit for someone who does not simply process what is placed in front of them. You should be comfortable recognizing when something does not match, researching the issue, communicating with the right people, and getting it resolved.
What You’ll DoReview and process purchase orders, invoices, vouchers, receipts, and supporting documentation
Enter and maintain Accounts Payable transactions in the financial system
Research and resolve complex invoice, payment, PO, and vendor discrepancies
Review transactions for accuracy, completeness, and proper supporting documentation
Identify errors or missing information and work directly with internal departments to resolve them
Process vendor additions, updates, and changes
Reconcile vendor statements, invoices, payments, and related financial records
Perform daily data validation and identify inconsistencies before they create downstream issues
Maintain and analyze detailed Excel spreadsheets used for tracking, reconciliation, and reporting
Use Excel functions including Pivot Tables, VLOOKUP/XLOOKUP, formulas, filters, and data validation
Monitor outstanding AP items and follow issues through completion
Communicate with vendors, program managers, and internal staff regarding invoice and payment concerns
Help ensure transactions follow established accounting procedures and internal controls
Assist with audit requests, reporting, and special accounting projects as needed
Adapt to changing systems, procedures, and business needs
Associate degree or higher in Accounting, Finance, or a closely related field
Several years of recent, hands-on Accounts Payable experience
Strong knowledge of the AP process, including purchase orders, invoices, vouchers, vendor records, payments, and reconciliations
Experience independently researching and resolving AP discrepancies
Strong Excel skills, including Pivot Tables and lookup formulas
Experience using Workday
Ability to work accurately with high volumes of financial data
State or local government accounting experience
Experience resolving complex PO, invoice, vendor, or payment issues
This role requires more than basic invoice processing.
We are looking for someone who can take ownership of AP issues, recognize when something is wrong, research the problem, and determine what needs to happen next.
You should be comfortable working with limited supervision and handling more complicated AP transactions and discrepancies without needing step-by-step instruction.
