Really useful now we can allocate credits to customers, as plenty of our clients don't like using credit cards for work, but invoicing each campaign is a big pain. One thing - can you add the ability to buy prepaid credits using GBP? Not having to worry about vagaries of exchange rates would be most handy.
Thanks for your feedback. It's not something we are currently planning - keeping our base rates in USD and having all designer costs paid in USD is the core of our business too. We'd have to keep changing the prices ourselves to support other currencies, and it would be a very time consuming operation, with lots of potential admin and confusion.
So at the moment, it isn't in the cards, but we do appreciate your point.
