As an accounts receivable accountant, your duties are to issue an invoice or billing statement for each payment due to a company, track incoming cash flow, and report late transactions. In addition to billing duties, you make a record of each payment in the department ledger and report unusual account activity. If you work in a senior position, you may check the work of clerks and verify payment records at the end of each day. An accounts receivable accountant typically uses software to handle their recordkeeping responsibilities. In some cases, you may inquire with customers or clients about unpaid bills.
