Abowire reminds me a lot like PayPal, a dead-simple way to collect payments but the main drawback is that they currently only support EU and not the US. The 1-taco deduction from me is the lack of US support, which I think could be a huge-milestone for this company.

Here's what's awesome about Abowire.
1. The signup process was easy and you're right to getting setup. As I mentioned before, it's simple like PayPal so you're pretty much ready to collect payments right out of the box
2. The menu is dead-simple, the main areas of focus is Customers, Transactions, Subscriptions and Invoices
3. Managing an invoice/subscription is dead-simple. Doesn't seem like you can manually add a subscription, but there's nifty filters and exporting functions.

The only major con I see and it may be temporary is the lack of support for US Banks. So you can't sync your US bank with Abowire.
The payment gateways they support and push towards is Stripe and PayPal, so technically, you can get to processing payments even if you're out of the EU.

Looking forward to seeing how Abowire progresses!
