Hi - we are developing an online service to which users will be able to buy subscriptions and purchase additional ad-hoc services. We are weighing up whether to build a subscription management solution or use something like Chargebee.com. Alternatively we could build this logic ourselves and link through to an online accounting package such as Xero. Advice greatly appreciated. PS - we are in the UK and in addition to taking card payments we also need to be able to setup direct debits and are planning to use Go Cardless to achieve this - just something to throw into the mix. Cheers Ed.
