Accounts Receivable & Billing Specialist | Collections | Invoicing

I am an Accounts Receivable and Billing Specialist with 7+ years of experience in billing, invoicing, collections, bookkeeping, customer support, and financial account management. I have hands-on experience with QuickBooks, Odoo, Shopify, Oracle, ERP systems, Excel, and Zendesk, including purchase order validation, invoice processing, payment and subsidy reconciliation, refunds, account audits, and customer collections. Throughout my career, I have worked with finance, customer service, school, sales, and operations teams to resolve billing discrepancies, follow up on outstanding payments, maintain accurate records, and provide reliable customer support. I also have experience managing customer accounts, billing portals, contracts, and financial documentation. I am detail-oriented, organized, and comfortable working independently in remote environments. My goal is to help businesses keep their accounts accurate, payments on track, and customers properly supported.
