The Staff Accountant will manage customer billing, accounts receivable, collections, and cash application, while supporting the Corporate Controller with general accounting and the monthly close. The role works closely with U.S.-based leadership, project managers, account executives, and customer AP contacts, so strong professional English is essential. U.S. company or GAAP experience is a plus.

Key Responsibilities

Customer Billing

• Prepare and issue accurate customer invoices in accordance with customer contracts, Statements of Work, purchase orders, billing schedules, and other contractual requirements.
• Before billing, confirm the customer legal entity and billing address, contract/SOW terms, PO requirements, billing rates, payment terms, project dates, billing frequency, and any required supporting documentation.
• Prepare invoices for multiple engagement types, including time-and-materials, fixed-fee, milestone-based, monthly managed services, staff augmentation, retainers/prepaid services, and reimbursable expenses.
• Reconcile approved timesheets and expenses to project records before invoicing, and obtain any missing timesheets, approvals, or POs.
• Ensure invoices include all customer-required support (approved timesheets, expense receipts, milestone acceptance documents, PO references, etc.) and submit through the required channel (email, AP portal, or procurement system).
• Monitor invoice acceptance, correct rejected invoices, and maintain the monthly billing calendar so invoices are completed on schedule.
• Identify services delivered but not yet invoiced and prepare unbilled-revenue schedules for the Controller.
• Maintain organized electronic billing records and help document and improve the billing process.

Accounts Receivable Management

• Maintain accurate AR records for all customer invoices, payments, credits, and adjustments.
• Review the AR aging report regularly and perform timely, professional collection follow-up with customer AP contacts.
• Obtain and document expected payment dates, customer responses, disputed amounts, and escalation status in detailed collection notes.
• Investigate overdue balances and resolve billing/payment issues such as missing POs, incorrect rates, rejected or duplicate invoices, disputed hours, and short payments.
• Escalate significant collection issues, customer disputes, and credit risks to the Corporate Controller.
• Prepare weekly AR aging and collection-status reports, and support AR forecasting and cash-collection schedules.
• Monitor customer payment patterns and support management's evaluation of credit risk, allowance for doubtful accounts, and potential write-offs.

Cash Receipts and Cash Application

• Monitor bank activity for customer receipts and apply customer payments accurately and promptly (ACH, wire, check, card, and other approved methods).
