Senior Billing Operations Specialist

RESPONSIBILITIES
Review billing files before release, validating rates, minimums, account eligibility and status, duplicate or overlapping lines, legal entity, credits, and exceptions.
Maintain a documented sign-off process and audit trail for every billing release.
Own the intake-to-application process for checks and ACH, including remittance logging, endorsement standards, deposit evidence, and matching to invoices.
Manage unapplied-cash exceptions and reconciliation to AR/GL, and prevent collections notices from going out while a payment is under active reconciliation.
Track credits and refunds from approval through customer receipt, investigating variances and coordinating rebills.
Establish service levels and aging visibility for open credits and disputes.
Serve as the Finance point person for customer-impacting billing issues, providing verified facts, an owner, a due date, and a next update.
Partner with CX on customer language and adoption-risk prioritization.
Build SOPs, checklists, a RACI, exception queues, approval rules, and root-cause logs, converting repeated one-off fixes into scalable controls and automation requirements.
Translate real billing defects into Quote-to-Cash requirements and test cases; maintain a living “will solve / will not solve / unknown” list.
Lead UAT for billing and reconciliation scenarios, and own exceptions after launch.
Report on first-pass accuracy, invoice timeliness, reconciliation aging, unapplied cash, refund cycle time, repeat defects, customer-impacting incidents, and CSR/GTM hours redirected to billing work.
Partner closely with the Senior Revenue Controller and broader Finance team on accounting-side accuracy, while owning the day-to-day operational and customer-facing side of billing independently.

REQUIREMENTS
5+ years in billing operations, order-to-cash, revenue operations, accounts receivable, or finance operations.
Hands-on reconciliation experience across billing, CRM, ERP/GL, bank, check, and CSV-based data.
Strong Excel and data-validation skills, with experience in root-cause analysis, controls, and audit documentation.
A track record resolving complex billing disputes, credits, and refunds.
Able to translate financial facts for customer-facing teams without losing control discipline.
Comfortable influencing & partnering with Finance, CX, Product, RevOps, and Engineering without direct authority.
Experience with billing-system implementations, requirements gathering, and UAT.
Senior enough to redesign a process, not simply absorb tickets into an existing one.

Preferred Qualifications
Experience with NetSuite, DealHub, Stripe, or similar billing/ERP and payments platforms.
Experience in a B2B SaaS or fintech environment.
Experience partnering directly with Customer Success/Experience teams on billing-related escalations.
