"Modern technology, fast support, clean UI."

"The ability to sell products that are priced as a single license as well as those which use a subscription model. The ability to support both models as well as discounting has been a great help. The ability to also target any market globally has really allowed us to be a global company without the headaches normally associated with selling in many different countries."

"First, FastSpring has outstanding customer service. I have used other providers in which it took a long time to receive any response. This has never been the case with FastSpring. if I have a tough problem I often have multiple responses to my various questions within the same day. Getting paid twice per month. It is a much better for cash flow purposes to see the revenue being available..."

"If I ever had a question, they are very prompt at getting back to me with either a solution or suggestion to solve my question."

"- they process the payments - they handle all sales taxes - they support per-product, per-email, and per-use coupons - they can present activation codes or other keys at the end of the sale - support for ordering issues is fast and accurate"

"FastSpring is very reliable. When a customer orders one of my books, FastSpring handles the download and charges any applicable taxes, no matter what country the customer is located in. FastSpring also checks for indicia of fraud to ensure the payment is secure. One of the best features is that FastSpring's support staff deals with customer inquiries, as well as my own questions, very quickly..."

"Great feature set, reliable, and very responsive support. When I originally evaluated eCommerce providers back in 2012 I did a comprehensive scan of the current providers vs implementing my own ecommerce system. FastSpring stood out back then due to features, integration, and UX/CX. They have been a reliable partner since then."

"Once set up, FastSpring automatically takes care of everything for you: receiving the customer's payment, generating and sending the license key and invoice and declaring VAT (if required). It's a great solution if you'd rather spend your time on more productive activities. FastSpring is very friendly to small developers: no monthly fees (unless your account is abandoned) and very low payment..."

"Very easy to set up, you can have an e-commerce site up and running in less than a day. For that you get the ability to sell internationally via credit card, paypal, wire transfer and accept cheque without the need for a merchant bank or registering for VAT in the UK or EU. In other words, its a one-stop-shop for e-commerce particularly suited for software vendors and startups. I also like..."

"The speed of customer support. I don't need it often but when I do, they are quick to reply and resolve problems faster than any service I use."
