I'm looking for an integrated payment handling solution for my startup but am cautious of PayPal given all the horror stories. The Amazon solutions aren't particularly attractive and they're not available in the UK afaik. Has anyone had experience with Google Checkout?
My ideal would be something like http://www.braintreepaymentsolutions.com/ -- they look awesome but are unfortunately US-only. There seems to be a UK-clone http://subsify.com/ -- but they haven't launched yet. Anyone know of any alternatives and care to share their experiences?
For instance, if you're expecting a higher-than-normal sales volume (e.g. a launch day, version upgrade, promotion), it doesn't hurt to give their Merchant Services department a phone call (the number I was given was 866-837-1851).
Be sure you ask for Merchant Services if you're not connected to them by default—it's a whole other support organization from what I could gather on my last phone call with them a month or so ago.
They may be taken aback by the reason for your call, but you can go over your phone numbers and addresses with them to make sure they can get a hold of you in the event that a fraud trigger is hit. If they can't speak with you, they have no other choice but to shut you down until you call them.
You can also get them to put a note on your account about the expected volume increase, so that when the activity does go into review, it may not be such a harsh reaction (e.g. freezing withdrawals temporarily rather than totally shutting down incoming funds.)
For the price of their service, the wide range of things you can do with their APIs, and the support I've received thus far, there's not a whole lot left to complain about IMO. Maybe my tune will change if I experience some of the "trouble" you hear about online, but I think that the proactive approach I describe above may help prevent that from ever happening.
