Job description

We’re looking for a Billing & Office Manager to help manage the day-to-day administrative and billing side of our plumbing, HVAC, and electrical company.

This person would work closely with management and take ownership of many of the daily office tasks that currently require management involvement.

Main responsibilities would include:

• Overseeing billing and making sure completed jobs are invoiced accurately and on time
• Reviewing technician paperwork, estimates, invoices, signatures, photos, POs, and job documentation for completeness
• Following up with technicians/managers when information is missing
• Uploading invoices and documentation to customer/property management portals
• Managing customer statements, account balances, credits, and billing corrections
• Assisting with collections and following up on past-due invoices
• Tracking POs and customer billing requirements
• Helping manage ServiceTitan job completion and making sure jobs aren't sitting unfinished or unbilled
• Reviewing payroll adjustments/commissions and helping prepare information for payroll
• Helping oversee dispatch/office workflows and making sure procedures are being followed
• Handling customer billing questions and resolving discrepancies before they need to be escalated
• Maintaining organized customer/property records and account information
• Helping create and enforce office procedures and keeping the team accountable
• Assisting management with reports, follow-ups, and administrative projects as needed

We are a very heavy multifamily service company, so experience working with apartment communities, property management companies, vendor portals, POs, ServiceTitan, or a similar service-management system would be a huge plus.

The biggest thing we're looking for is someone who is organized, proactive, detail-oriented, and comfortable taking ownership. We don't want someone who needs to be given a list every morning—we need someone who can recognize what needs attention, follow through, and help keep the office and billing side running smoothly.

• This would be a great position for someone with experience as an Office Manager, Billing Manager, Service Company Administrator, AR/Billing Specialist, or Operations Coordinator who is ready to take on more responsibility.
