FAQ about yearly payment

FAQ about yearly payment What is a yearly payment? You pay yearly for your HackMD subscription. Yearly payment is available for Prime Personal and Team plans. A year begins on the day of the yearly payment and ends on the same calendar date next year. Why would I pay yearly instead of monthly? You get a nice discount for paying yearly and the pricing is fixed until the yearly billing cycle ends. If the subscription of HackMD qualifies reimbursement at your organization, it is much better done once per year instead of per month. That's 91.7% less bureaucracy!
