AR Specialist

About the role

Mishimoto is a company dedicated to providing performance cooling and engineering solutions for car enthusiasts. The company is expanding rapidly, aiming for $100M in revenue within the next few years. The role of Accounts Receivable Specialist is a new, dedicated position created to manage AR processes effectively as the company grows.

Responsibilities

• Own the end-to-end AR process: invoicing, cash application, collections, and aging across DTC, B2B, and Marketplace channels.
• Reconcile Amazon Seller Central and Vendor Central settlements, tying remittances back to orders, fees, chargebacks, reimbursements, and deductions line by line.
• Reconcile eBay Managed Payments payouts against orders, refunds, and marketplace fees, resolving discrepancies before they age into write-offs.
• Investigate and dispute short-pays, unauthorized deductions, and chargebacks across marketplace and B2B accounts, tracking recovery to close.
• Maintain accurate AR aging reports and drive proactive collections on past-due B2B accounts.
• Partner with the Accounting Supervisor and Controller during month-end close on AR-related journal entries, accruals, and reserve analysis (bad debt, chargeback reserves).
• Serve as the go-to AR resource during audits, producing clean, well-documented support on request.
• Identify and flag systemic reconciliation issues—fee structure changes, mapping errors, recurring deduction codes—rather than just clearing the queue transaction by transaction.
• Work cross-functionally with Marketplace/Ecommerce Ops and Customer Service to resolve order-level disputes that block cash application.

Requirements

• 7–10 years of hands-on Accounts Receivable experience.
• Meaningful, specific experience reconciling Amazon (Seller Central and/or Vendor Central) and eBay marketplace payouts.
• Average or Associate's degree in accounting or finance, or equivalent experience.
• Comfort working directly in marketplace seller/vendor portals.
• A solid understanding of marketplace fee structures, including referral fees, FBA/fulfillment fees, chargebacks, returns, and promotional deductions.
• Strong Excel/spreadsheet skills for reconciliation work.
• Ecommerce, DTC, or consumer products industry background.
• Experience with NetSuite or a similar ERP system for invoicing and cash application.
• Comfort with BI tools (Tableau or similar).
• Experience in a multi-channel business (DTC + B2B + Marketplace) with high SKU count.
• Familiarity with Snowflake or similar data warehouse environments.
• Automotive aftermarket or performance parts industry experience.

Qualifications

• Detail-obsessed—resolving even small discrepancies is important.
• A self-starter who takes ownership of a function rather than waiting to be told what's next.
• Motivated by building something clean and repeatable, not just clearing today's backlog.
• Genuinely interested in cars and the enthusiast space—excited to learn about the industry.

Benefits

This role is based at Mishimoto’s headquarters in Garnet Valley, PA.
