What does an Invoicing specialist do?
An invoicing specialist prepares, reviews, and issues customer invoices to secure timely payment for goods or services. This role bridges the gap between completed work and collected revenue by translating operational data into accurate billing documents. The specialist verifies that every charge aligns with contracts or service tickets before submission. They also track each invoice through the approval process to resolve disputes and maintain clear receivables records.
- Review billing inputs such as service tickets, contracts, or job data to verify that amounts, tax codes, and customer profiles are correct. Investigate any discrepancies in the source data and coordinate with internal teams to correct errors before generating the final document. This step prevents rejected invoices and reduces the need for later corrections or credit memos.
- Prepare and submit customer invoices through designated channels, which may include specific client portals, email systems, or enterprise resource planning platforms like Vista by Viewpoint ERP. Follow customer-specific submission guidelines precisely to avoid administrative delays. Export or print supporting documentation when required by the client’s accounts payable department.
- Monitor invoice status after submission and follow up on items marked as pending, rejected, or disputed. Communicate directly with customer accounts payable contacts to obtain remittance details and clarify billing questions. Update internal tracking logs to reflect the current state of each invoice and ensure no bill falls through the cracks.
- Maintain detailed billing records, including invoice status tracking logs and receivables aging reports, using tools like Excel or specialized software such as OpenInvoice. Analyze these reports to identify overdue payments and prioritize collection efforts. Keep all digital files organized so that audit trails remain complete and accessible for finance teams.
