Pentagon Technologies is seeking a detail-oriented Accountant – AR to own day-to-day accounts receivable operations for a high-volume, multi-site business serving leading semiconductor and industrial customers. The role covers the full AR cycle — billing, cash application, account reconciliation, aging analysis, and collections support — and plays a key part in the company’s weekly cash and AR reporting. This is a hands-on position for someone who takes pride in clean subledgers, accurate cash application, and reliable reporting, with room to grow into broader accounting responsibilities.

Billing & Invoicing

• Generate, review, and issue customer invoices accurately and on time from the ERP, ensuring alignment with sales orders, shipping documents, and customer purchase orders
• Process credit memos, rebills, and invoice adjustments with proper documentation and approval
• Maintain customer billing requirements (portals, PO references, consolidated billing, special formats) and ensure invoices are submitted through the correct channel for each customer
• Research and resolve billing discrepancies and disputed invoices in coordination with sales, operations, and customer contacts

Cash Application & Deposits

• Apply customer payments (ACH, wire, check, credit card) to open invoices daily, accurately and completely, including handling of short pay, overpayments, discounts, and unapplied cash
• Prepare and log check deposits promptly in accordance with company policy on undeposited receipts; escalate stale or replacement-check situations
• Investigate and clear unapplied and on-account cash, and work old credit balances toward resolution (refund, offset, or escalation for write-off review)

Collections Support

• Support the AR & Collections Manager and collectors with account research, statements, invoice copies, and payment histories
• Monitor assigned accounts for past-due balances based on each customer’s payment terms, send dunning/reminder correspondence, and document collection notes and promised payment dates
• Escalate at-risk balances, disputes, and accounts approaching 90+ days in line with the collection’s escalation process
• Contribute to the team’s collections KPIs (e.g., collection effectiveness, past-due percentage, DSO) and help track promised-vs-received cash

Reconciliation & Month-End Close

• Reconcile the AR subledger to the general ledger monthly; investigate and resolve differences
• Reconcile key customer accounts and statements, including complex multi-entity customer groups
• Prepare month-end AR schedules: aging by bucket, reserve/allowance support, credit balance listing, and unapplied cash listing
• Prepare journal entries related to AR (adjustments, approved write-offs, allowance for doubtful accounts support) for review
• Support the periodic write-off review process by preparing documentation for identified uncollectible balances

Reporting & Analysis

• Prepare the weekly AR aging extract and support the weekly AR/cash reporting pack (top customer balances, week-over-week movement, aging by terms)
• Maintain data quality in the aging report: customer names, collector/owner assignments, payment terms, and customer group mappings
• Assist with ad hoc analysis such as customer concentration, late-fee assessments, and cash forecasting inputs (promised dates and expected collections for the 13-week cash flow)

Customer Master Data & Controls

• Set up and maintain customer master records (billing addresses, contacts, payment terms, credit terms) with proper approvals
• Follow and help improve internal controls over billing, cash receipts, and credit memos; maintain SOP documentation for AR processes
• Support external audit and due diligence requests with AR confirmations, aging support, and transaction samples

• Bachelor’s degree in accounting, Finance, or a related field
• 2–4 years of AR or general accounting experience, preferably in manufacturing, distribution, or industrial services
• Working knowledge of the full order-to-cash cycle: billing, cash application, aging, and collections
• Strong Excel skills (XLOOKUP, SUMIFS, large data sets) and experience with a mid-market or enterprise ERP
• High accuracy, strong organization, and professional communication with customers and internal teams
• Preferred: Dynamics AX (Axapta) or D365 Business Central; semiconductor/high-tech customer base; customer billing portals; collections KPIs (DSO, past-due %)

Success in the Role:

• Cash applied daily and unapplied cash kept current; invoices issued on time
• Past-due (per payment terms) and 90+ day balances trending down on assigned accounts
• Weekly aging and month-end AR reconciliations delivered accurately and on schedule
