We're a New Jersey-based law firm with about 12 attorneys, and we've been growing steadily since we started. We handle a high volume of billing, around 150 to 200 invoices every month, and we take accuracy and professionalism seriously. Right now, our firm admin is juggling a lot, and we need someone who can take full ownership of our accounts receivable and payable processes so we can keep things running smoothly and give our team more breathing room.

We're looking for someone who thrives on details, loves working with numbers, and can keep multiple plates spinning without breaking a sweat. This role is all about precision and process, and if you're the kind of person who gets satisfaction from a perfectly balanced ledger and a streamlined workflow, you'll fit right in with us.

We're looking for a Billing and Finance Administrative Specialist who is detail-obsessed, reliable, and comfortable managing the full billing cycle from start to finish.

You'll be the go-to person for all things accounts receivable and payable, handling everything from monthly invoicing to payment processing and time entry reviews.

You'll be reporting to our Partners, Brian and Damien. They're hands-on, approachable, and deeply invested in making sure the firm runs efficiently and that everyone has what they need to succeed. They'll be your go-to for guidance and support as you take ownership of this critical role.
