Stripe: instant payment processing for developers
Stripe pretty much takes payment processing kicking and screaming into 2011. Merchant accounts are a serious drag. I've opened a few and they've been nothing but headaches (especially if you're young—nobody trusts you.) Couple that with getting a gateway account, dealing with credit checks, monthly fees, monthly minimums, slow people in the payments industry, PCI compliance...Stripe takes payments and put them behind a simple API. No crappiness and 1099 rules of PayPal. No more reconsidering the meaning of life like back when I had a merchant account. The only downside I see is the 7-day rolling batch (deposit to bank), versus the nightly batch from the merchant account, though I assume that is for fraud protection.Maybe if you're charging millions of dollars, you should use a regular merchant account. If you aren't, I'm telling you now: don't even bother with a merchant account. Just use Stripe.
