First, choose the certification course you want to take on the AAPC website, add it to your shopping cart, then click on the checkout box. You’ll then be asked to give your billing information. You’ll be given three payment options — a credit card, or one of our two financial aid options, Climb or Affirm. These options allow you to enroll for your training immediately while paying over time — via a modest down payment and easy monthly installments. All transactions are secure and encrypted. What’s important is that you pick the option that works best for you.
