Take a look at FastSpring. Global coverage for developer clients, their end users, payment methods/currencies located all around the world, and an embedded store SDK used to power such app stores as Adobe's new Exchange. Pricing includes international payment costs, int'l tax management, pci compliance, chargeback fees, file hosting, unlimited support, and all the merchandising functionality. Developers save months to years of work because it's an all-in-one service, the features are already there for the developer selling one time or recurring based payment products and services globally.
Anytime you collect less info, it makes your fraud screen less intelligent. But it is all a balancing act and much more an art than science to keep consumer inconvenience to a minimum while not having more chargebacks than you or your merchant account provider can live with.
Gotcha. In case it's helpful, FastSpring order pages are localized into these languages:
Arabic, Chinese (Traditional and Simplified), Czech, Danish, Dutch, English, French, German, Greek, Italian, Japanese, Korean, Lithuanian, Polish, Portuguese, Russian, Serbian, Spanish, Swedish and Turkish
FastSpring and SaaSy handle global tax collection, payment, etc. for desktop software, SaaS, and downloadable gaming companies. We are the merchant of record, so the vendor is not responsible for collecting and remitting taxes, we are. There is a large number of other functionality we enable software firms to outsource as well, with the intention of leaving developers to focus on building their companies, not dealing with e-commerce infrastructure, features, taxes, etc.
See FastSpring if you're looking to sell SaaS or downloadable software or games. No upfront or monthly costs, limitless, rapid-response support, free setup, and it's uniquely full service.
You might check out SaaSy.com. It's the all-in-one option for recurring global transactions which enables developers to avoid having to develop subscription management or e-commerce functionality separately.
