Accounts receivable collections is the process of ensuring that people who are behind on payments pay their bills and any interest they might have accrued. As an accounts receivable collector, your duties include getting customer and financial information from the sales department, contacting the customer by phone or mail, and determining an appropriate schedule for paying off the debt. Qualifications for this career include accounting aptitude, job experience with spreadsheets and other invoicing software, and math and negotiations skills. While many companies have an accounts receivable department, you can find work with specialized collection companies as well.
