Apparently now the "pay for" is optional :-) See https://taxcloud.net/ There's a Ruby gem (https://github.com/drewtempelmeyer/tax_cloud) and integration with some stock carts (https://taxcloud.net/partners/). And there's "Automatically files sellers' sales tax returns" listed as a feature (for "streamlined states", ?wtf) which sounds interesting. Haven't test-driven yet, so no implied endorsement but it certainly seems worth investigating :-) HTH, -- Hassan Schroeder ------------------------ hassan.schroeder at gmail.com http://about.me/hassanschroeder twitter: @hassan
