Billing Lead / Manager

About Xometry

Xometry (NASDAQ: XMTR) is the global AI-powered marketplace for on-demand manufacturing, connecting buyers with a worldwide network of manufacturing partners. We serve customers across the US and Europe, with operations spanning North America, Germany, the UK, Turkey, China, and India.

The Role

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.

• 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.
