• Own the Billing & Invoicing strategy and roadmap for a unified billing approach across the product portfolio, covering fee calculation, invoicing, credits/adjustments, residuals and reconciliation. • Lead discovery across the payments ecosystem to gather insights from merchants/partners and internal commercial teams. Similarly incorporate competitive/market research and product insights to identify friction, risk, and growth opportunities. • Define and maintain clear product requirements for payments billing use cases, such as pricing and fee schedules, tiered/volume pricing, minimums, pass-through fees, commissions, one-time fees, credits/refunds, feature bundling, and exception handling. • Partner with Engineering to deliver the new billing engine and single customer billing view, ensuring a robust model that supports payments artefacts (e.g., transaction/event lineage, product/merchant hierarchy, and traceability from source events to invoice lines). • Guide consolidation of existing billing workflows into the unified model, including migration planning, phased rollout, and cutover readiness, with a focus on billing continuity and customer impact. • Work closely with stakeholders to ensure correct application of tax rules, enabling compliant invoicing, accurate reporting, and clear auditability. • Encourage governance and controls that reduce commercial and financial risk such as pricing change discipline, approvals, audit trails, and tooling/monitoring to surface revenue leakage, and invoicing defects early. • Drive launches and adoption that include release planning, documentation, enablement for internal teams, and operational runbooks for billing cycles, exception management, and customer queries. • Monitor and improve outcomes using payments-relevant metrics such as billing accuracy, dispute/credit volumes, invoice timeliness, reconciliation variance, support contact drivers, and revenue optimization. • Act as the Billing domain SME, aligning stakeholders across Engineering, Finance, Sales, Legal/Compliance, and Marketing on changes that affect pricing, fees, customer communications, and financial reporting inputs. • Define and evolve hybrid billing capabilities - including SaaS subscriptions, usage-based models, and bundled offerings - ensuring the unified billing engine can support flexible pricing constructs and deliver clear, accurate, and explainable charges to customers.
