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.

Responsibilities

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.

Requirements
