Office Assistant - Billing and Scheduling

Hassig Companies is a family run commercial plumbing and mechanical contractor in downtown Mount Clemens. We are hiring an office assistant to help keep our jobs, subcontractors and paperwork moving.

This is a support seat, not a management seat. Our office manager runs the books and the money side. You keep the day to day moving: answering calls, getting work scheduled, staying on subcontractors and permits, and entering vendor bills and expenses in our job system. You will spend most of your day working inside accounting and job tracking software. If software frustrates you, this is not the job for you.

What you'll do

- Answer service calls and project requests by phone, email and customer portals. Quote our standard rates and get work on the schedule with customers and field crews.

- Track open jobs. Stay on top of next steps, material and equipment deliveries, and customer updates before anyone has to ask.

- Keep subcontractors moving. Confirm schedules, collect their paperwork, submit permit test reports and book final inspections with municipalities.

- Enter vendor bills, expenses and credits in our job system. Check job assignments, catch duplicates and missing information, and clean up the routine data problems that break the QuickBooks sync.

- Help the office manager with invoicing and follow up on unpaid balances.

- Enter and check crew time so weekly payroll goes out clean.

- Keep insurance records, certificates, driver lists and job files current.

What we're looking for

- Comfortable running real work through business software. QuickBooks Online, or any accounting, billing, dispatch or job tracking system. You should be able to find information, compare documents, fix entries, and notice when something doesn't add up.

- Some experience with vendor bills, data entry, scheduling or similar detailed office work. You do not need to have run a department.

- Able to keep status and next steps current across 20 or more open jobs without losing one.

- Professional and persistent on the phone and in email with customers, subcontractors and building inspectors.

- Accuracy with vendor bills and payroll records, and discretion with both.

- Available to work in person at our Mount Clemens office on the posted schedule.

We run our jobs in Airtable, which nobody arrives already knowing. We will teach you that part. What we cannot teach is being quick with software and careful with numbers. Construction, trades, service dispatch or property management experience is a plus, and we will teach you the plumbing side.

What we offer

- $23 to $28 per hour to start, based on experience

- Regular performance and pay reviews. Our people typically see a raise once or twice a year.

- Health and dental plan options available, including HSA eligible plans

- Paid holidays and Michigan paid sick time

- Monday through Friday, 8:00 to 4:00. No nights, no weekends.

- Company provided equipment and Hassig gear

- Small office. You work directly with the owner and the field crews.

We'll walk you through the full benefit package when we talk.

Where you'll work

Our office is at 237 Church St, Mount Clemens. We serve customers across Macomb and Oakland County, plus hotel and property management clients in several states.
