Portal Billing/Collections Specialist

Dagen is recruiting a contract Portal Billing/Collections Specialist for a manufacturing company in Los Colinas.

**Only qualified applications will be contacted.

Position Summary

The Portal Billing Specialist is responsible for the accurate and timely submission, tracking, and reconciliation of customer invoices through third-party billing portals (e.g., Ariba, Coupa, Tungsten Network, and other customer-specific AP/vendor portals) across Accredited Labs' 29+ business units and four NetSuite subsidiaries. This role acts as the critical link between NetSuite-generated invoices and the diverse portal requirements of our national account customers, ensuring invoices are accepted on first submission, portal rejections and disputes are resolved quickly, and portal-related delays are eliminated as a root cause of aged AR. The Portal Billing Specialist works closely with the Collections team and branch billing contacts to keep portal-billed accounts current.

Key Responsibilities

Portal Invoice Submission & Maintenance

• Upload, submit, and confirm receipt of customer invoices across all active third-party billing portals, ensuring formatting, backup documentation, and coding requirements are met for each portal.
• Maintain and continuously update a master portal registry mapping customers/BUs to their required portal, submission format, PO requirements, and portal-specific timelines.
• Monitor portal queues daily for rejected, pending, or flagged invoices and remediate within customer-defined turnaround windows.
• Coordinate with branch billing contacts and Collections to obtain missing POs, backup, or approvals needed for portal acceptance.

Reconciliation & Reporting

• Reconcile portal invoice status (submitted, pending approval, approved, paid, rejected) against NetSuite AR aging on a weekly cadence, tying portal-billed balances back to source aging files.
• Flag portal-driven aging – invoices held up by portal rejection, missing PO, or vendor-portal approval delay rather than a true customer dispute – and route to the appropriate collector or branch manager.
• Support the weekly AR aging and O2C dashboard process by supplying portal-status detail for accounts in the 91+ day bucket.
• Track and report portal rejection root causes (missing PO, coding error, duplicate invoice, portal timeout) to identify systemic fixes.

Qualifications

Required

• 2+ years of experience in billing, AR, or accounts payable operations, with direct experience submitting invoices through vendor/customer billing portals (Ariba, Coupa, Tungsten Network, or similar).
• Working knowledge of ERP systems; NetSuite experience strongly preferred.
• Strong Excel skills, including pivot tables and lookups, for reconciliation work.
• High attention to detail and comfort managing high transaction volumes across multiple entities and portals simultaneously.
• Excellent written and verbal communication skills for coordinating with branch contacts, collectors, and customer AP teams.
