Remote Invoicing Jobs in Texas (NOW HIRING)

Plumbing Invoicing & Accounts Receivable Specialist 

Location: Remote / Work From Home Position Type: Part-Time 

About Us 

Sofos Industries is a fast-growing plumbing service provider specializing in the property management industry. We work with property management companies that own and manage single-family homes and communities across multiple markets, providing reliable, cost-effective plumbing solutions. 

Our business is built around speed, competitive pricing, strong communication, and thorough documentation.  

Because we work with professional property management companies, accurate documentation, quick invoicing turnaround, and following each client's specific pricing and billing requirements are critical to our success. 

Position Overview 

This position is responsible for reviewing completed plumbing work orders, preparing accurate invoices, tracking accounts receivable, and following up on outstanding payments. 

This is not simply a data-entry position. We are looking for someone who can think critically and outside the box when reviewing completed work orders. The right candidate will understand how to review technician notes, photos, materials, labor, and completed work to ensure we are accurately capturing and invoicing all billable work performed, while remaining within each client's approved pricing and billing requirements. 

Invoicing is expected to be completed daily. Our clients expect a quick turnaround after work is completed, so the person in this role must consistently review, prepare, and submit completed jobs without allowing an invoicing backlog to develop. 

Our goal is to make sure our technicians' work is properly documented, invoiced, and accounted for without leaving legitimate billable revenue on the table.
