Job Description

Masterline Facilities | Full-Time | In-Office

Masterline Facilities is growing, and we’re looking for an additional Billing & Accounts Receivable Specialist to join our office team.

We are a fast-growing facilities maintenance company providing services across 15 states . Our team works hard, moves fast, and takes a lot of pride in what we do. As we continue to grow, we need another strong person on our billing and AR team to help make sure the work we complete gets billed correctly — and gets paid.

This is not just a data-entry billing position. We’re looking for someone who will take ownership of their accounts from billing through collection . 

What You'll Be Doing

You’ll work closely with our service team, customers, and management to keep billing accurate and our receivables moving.

Your day-to-day will include:

• Preparing and submitting customer invoices accurately and on time
• Reviewing completed work orders and making sure everything needed for billing is there
• Uploading invoices, photos, sign-offs, technician notes, and other supporting documentation into customer portals
• Working within customer systems such as ServiceChannel, Corrigo, and other facilities management platforms
• Managing assigned customer accounts and monitoring outstanding balances
• Reviewing aging reports and staying on top of past-due invoices
• Calling and emailing customers for payment updates
• Sending statements and collection follow-ups
• Researching rejected, short-paid, disputed, or unpaid invoices
• Following up on missing POs, approvals, NTE increases, or documentation holding up payment
• Keeping detailed notes on collection efforts and promised payment dates
• Communicating with our internal team when information or corrections are needed
• Helping reconcile customer accounts and payments
• Following an issue through until it is actually resolved

Who We're Looking For

The right person for this position is organized, persistent, and comfortable taking ownership .

If an invoice hasn’t been paid, you want to know why.

If a customer says, “The check is in the mail,” you make a note and follow back up.

If an invoice gets rejected, you figure out what happened and what needs to be done to get it paid.

You don’t need someone standing over you reminding you what needs to be followed up on — you keep track of it.

We’d love someone who:

• Has previous billing, Accounts Receivable, collections, or accounting support experience
• Is extremely detail-oriented
• Is comfortable picking up the phone and professionally asking for payment
• Has strong written and verbal communication skills
• Can manage a high volume of invoices without losing track of the details
• Is comfortable working in multiple systems and customer portals
• Can prioritize and manage their own workload
• Is willing to ask questions, learn, and problem-solve
• Works well as part of a team
• Can handle a fast-paced environment where priorities sometimes change quickly

QuickBooks experience is a plus.

Experience with facilities maintenance, construction, plumbing, electrical, service companies, or work-order-based billing is a major plus, but we’re willing to train the right person.

What It's Like Working at Masterline

We’re a growing company, which means things move quickly and there is always something going on. We work hard, help each other out, and don’t take ourselves too seriously.

We want people who care about doing a good job, communicate when they need help, and are willing to jump in when the team needs them.

This is a great opportunity for someone who wants to be part of a company that is continuing to grow and wants a position they can truly make their own.
