Accounts Receivable & Accounting Specialist

Position Overview

SimplyTest is seeking a detail-oriented AR Specialist to help drive an immediate accounts receivable cleanup initiative while supporting broader accounting operations. In the near term, this role will be heavily focused on aging AR, customer account cleanup, collections follow-up, payment reconciliation, and QuickBooks accuracy. Over time, the role will transition into a more balanced AP/AR function supporting accounts payable, vendor payments, reconciliations, and month-end close activities.

We are looking for someone who is highly comfortable working in QuickBooks, navigating messy or difficult AR, researching discrepancies, following through on outstanding balances, and bringing structure to accounting workflows in a fast-moving environment.

• Review AR aging reports, open invoices, customer balances, payment history, and account notes in QuickBooks.
• Research and resolve billing discrepancies, unapplied payments, credits, duplicate invoices, customer disputes, and account reconciliation issues.
• Follow up with customers on outstanding balances using clear, professional, and persistent communication.
• Send statements, invoice copies, payment reminders, and supporting documentation as needed.
• Document collection activity, customer responses, disputed items, and recommended next steps.
• Escalate high-risk, unresolved, or disputed accounts to management with clear options for resolution.
• Create and maintain AR trackers, collection notes, and status reports to improve visibility and accountability.

• Use QuickBooks to maintain accurate customer, vendor, invoice, payment, and account records.
• Generate, review, and analyze AR aging, open invoice, customer balance, payment, and reconciliation reports.
• Support cash application, customer account reconciliation, and correction of historical accounting issues.
• Support full-cycle accounts payable, including invoice processing, coding, approvals, and vendor payment preparation.
• Assist with vendor statement reconciliation, AP cleanup, and resolution of invoice or payment discrepancies.
• Support month-end close, account reconciliations, and additional bookkeeping or accounting tasks as needed.
• Partner with Finance, Operations, Customer Success, and other internal teams to resolve billing, payment, and account questions.
• Identify process gaps and help improve AP/AR workflows, reporting, documentation, and controls.

Qualifications

• Minimum of 5 years of bookkeeping, accounts receivable, accounts payable, or accounting operations experience.
• Strong hands-on experience with QuickBooks required, including AR aging, open invoice reports, customer accounts, payments, credits, reconciliations, and corrections.
• Demonstrated experience managing difficult AR, collections follow-up, past-due balances, customer disputes, and account cleanup.
• Solid understanding of AP/AR workflows, invoice processing, payment application, account reconciliation, and financial record accuracy.
• Strong Excel skills and ability to work with reports, trackers, reconciliations, and large volumes of account detail.
• Bachelor's degree or associate degree in accounting, finance, business, or a related field preferred; equivalent hands-on experience will be considered.
• Experience in healthcare, diagnostics, laboratory services, customer billing, or high-growth companies is a plus.

What We're Looking For

• A QuickBooks-proficient AR problem solver who can work through messy balances and bring order to aging receivables.
• Someone who is persistent and professional with collections follow-up and comfortable handling difficult customer account conversations.
• A detail-oriented operator who documents clearly, follows through, and does not let unresolved items sit.
• A team player who can work cross-functionally while still owning the AR cleanup process from start to finish.
• Someone who can help stabilize AR in the short term and grow into a broader AP/AR support role over time.
