About This Role

As a Part-Time Billing Specialist, you will ensure the accuracy and timeliness of invoice processing, from verifying purchase orders to reconciling client billing summaries. Your role is critical in maintaining CELCO’s financial integrity, allowing the organization to focus on its community and environmental initiatives without administrative bottlenecks.

💡 A Day in the Life

Your day starts by checking your email for invoice-related inquiries and prioritizing urgent requests.
