[Hiring] Accounts Receivable Intern, Cash Applications @ProSomnus

Role Description

This role begins with a focused scope on cash applications and broader Accounts Receivable support, with a clear opportunity to grow into a more typical collections role over time. To start, you will help match and apply incoming customer payments, research unapplied cash and discrepancies, and keep clean supporting documentation. As you build fluency in our systems and process, the role can expand into customer outreach, aging follow-up, and dispute resolution. This is a learning-focused position designed for a student or early-career candidate who wants hands-on exposure to the order-to-cash cycle in a real finance organization. You will work closely with the General Ledger Accountant.

Key Responsibilities

• Match incoming customer payments (check, ACH, credit card, and lockbox) to open invoices in QuickBooks Online (QBO).
• Research and resolve unapplied cash, short pays, and remittance discrepancies using order and customer data from Magic Touch.
• Maintain accurate records of applied and unapplied payments, and prepare items for review and posting by the accounting team.
• Help compile supporting documentation for AR and cash reconciliations in FloQast.
• Keep a running status of open items, with clear notes for the team.
• Support ad hoc reporting and projects for the finance team as needed.
• Monitor the accounts receivable aging and help identify past-due accounts for follow-up.
• Conduct courteous, professional outreach to customers (primarily dental practices and distribution partners) regarding open and past-due invoices.
• Draft customer statements and reminder communications for review before they are sent.
• Escalate aged or disputed balances, with a recommended next step, to the General Ledger Accountant.

A Note on Controls

The intern prepares, researches, and recommends. Adjustments, write-offs, cash posting, and final customer communications are reviewed and approved by the accounting team. This keeps a clear separation between preparation and approval.
