A payment poster oversees the intake of payments, often in a medical billing office. In payment poster jobs, your responsibilities include accepting payments, processing billing statements, and conducting audits for each billing cycle. While positions in medical facilities like urgent care are common, you can find work as a payment poster in a wide variety of industries. You will need at least a high school diploma or GED certificate for this career, but a post-secondary degree may be preferred by employers. Experience in other clerical or billing positions can help you hone the skills necessary for payment poster positions.
