Senior Billing & A/R Analyst

About the role:

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.

Where you will work:

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

What you will do:

• 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.

The ideal candidate has:

• 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

This is a unique opportunity to join a fast-growing company in a transformative role, helping shape the future of healthcare.

Tools you will use

QuickBooks Online, Netsuite, Salesforce, Modern Treasury, Snowflake, Google Sheets, client AP/supplier portals (Coupa, SAP), and a suite of internal AI/automation tools (Claude) that power recurring invoicing and reconciliation workflows.
