Job Title: Senior Accounts Receivable Specialist

Reports To: Accounting Manager

Work Location: Onsite in Norcross, GA

We are seeking a detail-oriented Senior Accounts Receivable Specialist to own the complete Accounts Receivable process from customer invoicing through month-end close. This role is responsible for billing, cash application, collections, dispute resolution, customer account reconciliations, credit management, and AR month-end close activities.

This is an excellent opportunity for someone who enjoys rolling up their sleeves, solving problems, and improving processes. Our Accounts Receivable function is currently highly manual, and we are looking for someone who will not simply execute the existing process but actively evaluate it, identify inefficiencies, recommend improvements, and help us build a best-in-class AR operation through standardization, automation, and continuous process improvement.

This position serves as the process owner for the Accounts Receivable function and plays a key role in transforming the department into a standardized, efficient, and scalable operation that supports the company's continued growth.

The ideal candidate combines strong accounting knowledge with exceptional customer service and analytical skills. They are naturally curious, take ownership of their work, communicate proactively, and enjoy collaborating across departments to improve both the customer experience and internal financial processes.

Key Responsibilities:

Customer Billing Support & Process Management

• Partner with the Sales and Account Management teams to ensure customer sales orders are entered accurately, resulting in timely and accurate customer invoices.
• Review invoice discrepancies, identify the root cause of billing errors, and work cross-functionally to implement corrective actions.
• Monitor billing accuracy and recommend process improvements to reduce invoice errors, credit memos, and customer disputes.
• Develop and maintain standardized billing procedures and partner with cross-functional teams to improve the Order-to-Cash process.

• Apply customer payments accurately and daily.
• Research and resolve unapplied cash and payment discrepancies.
• Reconcile customer remittance information and customer account balances.
• Investigate payment issues and coordinate resolutions with customers.
• Own the Accounts Receivable month-end close process, ensuring all AR activities are completed accurately and on schedule.
• Prepare supporting schedules, reconcile month-end balances, investigate significant variances, and ensure the AR subledger ties to the General Ledger prior to financial close.
• Reconcile the AR subledger to the General Ledger, ensuring completeness and accuracy of all balances.
• Accurately record all AR-related transactions in the ERP system (payments, credit memos, write-offs, allowances, adjustments, and other AR transactions).
• Reconcile and clear intercompany AP/AR balances, ensuring proper setup of customer master data and alignment across entities.
• Apply a strong understanding of accounting principles, including the proper accounting treatment for:
  • Credit memos
  • Refunds
  • Intercompany transactions
  • Allowance for doubtful accounts

• Lead proactive collection efforts, conducting dunning activities and following up with domestic and international customers to drive timely payment of open invoices.
• Monitor AR aging, proactively identify delinquent accounts, document collection activities, and elevate issues in accordance with company policy.
• Research and resolve complex billing issues, payment discrepancies, unapplied cash, and customer disputes.
• Process and validate customer credit memos and investigate irregularities in customer accounts.
• Recommend customer credit holds, payment plans, write-offs, and outside collections in accordance with company policy.
• Build strong customer relationships while maintaining consistent collection efforts.

• Partner with Sales, Account Managers, Customer Service, Operations, and Finance to improve the Order-to-Cash process, resolve billing issues, reduce invoice errors, and improve the overall customer experience.
