shinyapps.io is designed to be entirely self-service. We only accept payment by credit card in order to keep the costs of sales and order processing - and therefore prices - as low as possible.
However, we do offer a premium priced professional plan for shinyapps.io for US$5,500, which allows us to cover the cost of processing other forms of payment and providing some sales support for quotation. If that is of interest, please contact our sales team. Otherwise, you will need to use a credit card to purchase another plan. We are not able to provide quotes for the credit card plans.
