What I'm looking for
At Prime Secured Inc., I prepare progress and full invoices for security and service projects and maintain Accounts Receivable Aging reports. I also prepare Daily Liquidity reports and reconcile vendor invoices in QuickBooks.
At Lean Solutions Group, I processed drayage and accessorial invoices for U.S.-based clients, checking charges against contracts and supporting documents. I also maintained client-specific billing SOPs and monitored unbilled container reports.
Earlier, at Lean Solutions Group, I led a billing team and supported discrepancy resolution and payment follow-up. At Teleperformance – Expedia Inc., I evaluated customer service interactions for quality, compliance, and process adherence. I'm expanding my accounting knowledge through professional bookkeeping training, with a strong interest in accounts receivable, accounts payable, and broader accounting operations.
