AR Billing Specialist improving invoicing accuracy, reconciliation, and O2C cash flow.
IndiaWhat I'm looking for
I’m an AR Billing Specialist with 3+ years of experience in invoice management, billing reconciliation, and O2C operations across global shared services. I generate and dispatch invoices, maintain billing schedules, raise credit notes, and follow up on outstanding balances for designated customer portfolios. I also verify billing data for completeness and accuracy before dispatch.
Across my roles, I’ve resolved over $500K in billing discrepancies and improved billing accuracy with a 93% data quality score and a 15% reduction in billing errors. I take ownership of billing cycles end to end—tracking unbilled revenue daily, managing multi-currency invoice processing, and resolving billing exceptions within SLA. I support month-end close through AR aging reports and billing summaries.
I’m proactive about process improvement. I identified invoice security and knowledge gaps and led two initiatives that were adopted across the team: a secure internal invoice consolidation tool (removing third-party dependency) and a Billing Process Knowledge Library with digital SOP walkthrough videos. My focus is consistent execution, compliant controls, and faster, more accurate billing outcomes.
