Ensure reports are consistent, traceable, and repeatable.
Help identify and investigate variances.
Build and document clear workflows and SOPs.
Establish daily, weekly, and monthly checklists across billing and AR.
Implement validation and control steps to improve accuracy.
Drive adoption and enforce adherence across the team.
Support implementation of daily and weekly reporting cadence.
Track key metrics including:
- AR aging and past due balances
- Billing timeliness and accuracy
- Collections activity and follow-up
Improve visibility into team performance and operational health.
Provide day-to-day structure and oversight for billing and AR activities.
Help enforce deadlines, track tasks, and ensure follow-through.
Support training and standardization across the team.
Drive accountability for deadlines, deliverables, and performance expectations.
Reinforce structured ways of working and reduce ad hoc execution.
Billing is timely, accurate, and consistently executed.
AR reporting and reconciliations are stable and explainable.
Core processes are supported by clear checklists and workflows.
Team execution improves with better visibility and accountability.
5-10 years in AR, billing, or accounting operations.
Experience in high-volume or multi-system environments.
Strong attention to detail and process orientation.
Comfortable working in less structured environments and creating order.
Hands-on, proactive, and execution-focused.
Strong Excel skills (ability to work with large datasets and reconcile data).
Experience stepping into environments that lack structure and building process from the ground up.
This role is focused on execution and stabilization, with the opportunity to expand into a broader role depending on performance and business needs.
