Monitor accounts receivable activity, support collections efforts, and work directly with customers to resolve outstanding balances, remittance questions, and payment delays.

Track and manage billing exceptions, credit memos, invoice adjustments, and dispute resolution through completion.

Maintain customer master data, billing profiles, invoice delivery preferences, contract terms, purchase order requirements, and pricing schedules within the ERP system.

Prepare and analyze billing and collections metrics, including invoice accuracy, billing cycle times, dispute aging, DSO trends, collections performance, and cash application reporting.

Support month-end close activities by ensuring billing, receivables, accruals, and related reconciliations are completed accurately and on schedule.

Identify opportunities to improve billing workflows, reporting capabilities, automation, and internal controls across the order-to-cash process.

Assist with ERP optimization initiatives, process documentation, and ongoing finance transformation projects.
