Bill and account collector are people who talk to debtors and try to collect a payment of balance that is due for a product or service. Most bill and account collectors handle their business through telephone, but sometimes it is necessary for them to meet in-person if the calls do not produce the results as expected. i.e., a company does not want to pay for a service that was provided. Most bill and account collectors if not all are required to have a high school diploma, although some companies prefer people who have taken some college courses on communications, accounting, and basic computer courses. Bill and account collectors also must be persuasive, good under pressure and organized for them to earn them job. A Bill and Account Collector earns a pay level between $26,960 and $58,940 based on seniority.  Collectors usually get 1 to 3 months of on-the-job training after being hired. Training includes learning the company’s policies and computer software and learning the laws for debt collection in the Fair Debt Collection Practices Act, as well as their state’s debt-collection regulations. Collectors also may be trained in negotiation techniques, depending on the employer.
