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.
