Hi,
We use Bluesnap due to security, tax collection, and tax payment issues. We sell worldwide, and the different tax rates and rules for all the different countries where we have customers would make the collection and documentation a boatload of work - we prefer to focus on quality software
Bluesnap already has the mechanisms in place to keep customer information secure, as well as to collect and pay the various taxes that are required by different countries.
ttfn,
Sherry
