Billing Lead / Manager

We're hiring an experienced individual contributor to own end-to-end invoice submission and lifecycle management across our customers' AP e-invoicing portals (Coupa, Ariba/SAP Business Network, Tungsten, OpenInvoice, Taulia, SAP, Fieldglass, customer-specific portals, etc.). Our US enterprise customer base, and a growing slice of European accounts, increasingly require invoices be routed through their procurement platforms, with strict PO matching, line-level formatting, and document standards. This role is the subject matter expert who makes that work flow cleanly and at scale.

This is a hands-on IC role with leadership scope: you'll set the standards, drive process improvements, and serve as the escalation point for the broader O2C team, but you won't have direct reports.

What You'll Do

• Own daily submission, tracking, and resolution of customer invoices across e-invoicing and AP portals, ensuring on-time delivery and adherence to each customer's billing rules.
• Investigate and resolve rejected, disputed, short-paid, or stuck invoices, partnering with Sales, Operations, and customer AP teams to drive quick resolution and minimize DSO impact.
• Onboard new customers to e-portal billing: gather portal credentials and PO requirements, configure templates in NetSuite (or downstream tools), and document customer-specific SOPs.
• Maintain a living playbook of portal-specific requirements (PO formats, tax fields, supporting documentation, cXML/EDI specs where relevant).
• Partner with IT/Finance Systems on automation initiatives, e.g., direct integrations, EDI/cXML feeds, RPA, to reduce manual touchpoints as volume scales.
• Track KPIs (first-pass acceptance rate, average days to acceptance, rejected invoice aging, portal-specific DSO) and surface trends to controllership leadership monthly.
• Support month-end close activities related to billing accuracy, unbilled revenue review, and reconciliation of portal-side balances vs. NetSuite AR.
• Coach AR analysts and billing specialists on portal nuances; act as the go-to escalation point for complex customer billing issues.
• Support SOX controls related to billing and invoice processing, including audit walkthroughs and evidence requests.

Nice to have

• Experience supporting public company through SOX 404 controls testing.
• Exposure to manufacturing, marketplace, or two-sided platform business models.
• Familiarity with cXML/EDI 810/EDI 850 standards.
• Experience with European e-invoicing mandates (Peppol, Italy SdI, France
• Chorus Pro, Germany B2B mandate).
• SQL or Power BI/Tableau for self-service reporting.
