We're a Foundation with board members across various countries. We have some difficulty setting up a bank account. It's definitely easier to create a Bitcoin wallet, but we want more than that.

Here are some conditions:

• We want to keep track and control funds without too much overhead.
• We want unique addresses for each donation, so a e.g. multisig electrum wallet wouldn't be ideal.
• We don't mind relying on a 3rd party service.
• We don't have a bank account yet (so BitPay might not work for us).

What would be a good solution for us?
