Senior Billing & A/R Analyst

We are looking for an exceptional Senior Billing & A/R Analyst to join our Finance team. You will own Garner's monthly client invoicing and Accounts Receivable function end to end — a high-volume, high-visibility platform with complex internal and external requirements. You will oversee the production and distribution of ~800 invoices per month, own the controls, validation and review processes that ensure complete and accurate invoicing, manage collections and the A/R inbox, and keep cash application current to support a timely month-end close. 

You'll join a Finance organization that has invested heavily in automation. Much of the recurring work is already automated through a suite of internal AI tools (Claude "skills"), and you will be responsible for operating, maintaining, and continuously improving that tooling rather than recreating manual processes. Beyond running the day-to-day function, you will own the KPIs that measure Billing and A/R performance, identify opportunities to strengthen our processes and controls and drive improvements that make the function more accurate, efficient and scalable.

Garner is headquartered in NYC, but this position is available for individuals who are comfortable with remote work and occasional travel to HQ.

• Own the monthly invoicing process end to end. Manage the invoicing queries and tooling, build and release invoice batches, and generate and distribute ~800 invoices per month across standard, self-bill, and bespoke client arrangements.
• Ensure complete and accurate invoicing. Own the controls, validation and review processes across invoice completeness, plan coverage, rates, invoicing groups, and banking data. Investigate and resolve exceptions with cross-functional partners and ensure adjustments and client-specific requirements are accurately reflected.
• Own Accounts Receivable & collections. Manage the A/R balance from issuance through cash receipt; including collections and follow-up on overdue balances, ACH pulls and re-attempts; and timely cash application and deposit classification to support month-end close.
• Manage billing inquiries and issue resolution. Own the A/R inbox and respond to client, broker, and internal billing questions within established service level agreements, coordinating with internal teams to resolve issues efficiently. 
• Leverage and continuously improve our automation. Use our internal Claude skill suite as the default way to run recurring tasks (self-bills, cash application, dashboards, batch QA), and improve those skills as the business continues to evolve.
• Maintain client billing data and portals. Keep invoice contacts, terms, and banking details accurate; maintain Garner's presence in AP/supplier portals (Coupa, SAP, and others).
• Own Billing and A/R performance metrics. Track and report the metrics that measure invoicing completeness/accuracy and collections effectiveness (DSO, AR turnover, aging, invoice error rate, on-time batch rate, SLA attainment), and act on what they show.
• Maintain strong processes and documentation. Keep SOPs and the shared system of record current and legible enough that a teammate can run any part of this function cold — no single points of failure.

• Experience owning Billing and Accounts Receivable processes, ideally in a high volume environment, with experience using QuickBooks Online, Netsuite or similar financial systems.
• Strong understanding of A/R and collections, including DSO, aging, cash application, and the operational drivers of collections performance.
• Strong analytical and reconciliation skills, with the ability to identify variances, trace issues across multiple data sources, and drive them through resolution. Experience with Salesforce, Snowflake/SQL, or similar tools is a plus.
• A continuous-improvement mindset with an interest in using automation and AI to make recurring processes more accurate, efficient and scalable.
• An ownership mindset with the ability to independently manage the function, identify issues and risks, and partner across teams to resolve them.
• Meticulous attention to accuracy and controls, with a disciplined approach to validating work and identifying issues before they impact clients or financial reporting.
• Clear and proactive communication, with the ability to manage competing priorities, meet deadlines and service level agreements, and escalate issues appropriately.
• A problem solving mindset with an eagerness to dig into issues, investigate root causes, and document the problem and steps to resolution.
• A desire to be a part of a high-performing, mission-driven team that operates with intense urgency, a strong sense of individual accountability, and a commitment to authentic feedback
