FastSpring is definitely the best company I have ever interacted with (note: the best company ever, not just related to e-commerce).

After switching to FastSpring, our sales increased over 15%. We experienced a significant increase in order size due to the better implemented shopping cart functionality.

I have changed to FastSpring and couldn't be happier. Their system allows a fully customizable email to be sent to purchasers. Now I can send just the instructions needed to license Text2Go, which are now not much more than 'click this link and you're done.' Their order page customization is also very flexible, although I don't really make full use of this asI have my own shopping cart page and just jump directly to the FastSpring checkout page. The FastSpring administrators' interface is a joy to use. It has a gorgeous web 2.0 look and more importantly is very responsive. It's layout is all very logical and it has really useful context sensitive help on each page. I found this was more than adequate and didn't have to read through their user manual at all. FastSpring prides themselves on great support and that's definitely been my experience. Their staff are all very knowledgeable and they respond within a few hours, even on weekends.

I must say FastSpring has been a pleasant surprise. We literally tested 8 different e-commerce solutions. With each one, we started with the intention of it being the one we would use. But, then, somewhere along the way, we would get stuck; or there were too many hurdles to get a particular feature to work; or customer support was too slow to respond; or it wasn't possible to test the entire checkout experience (including the receipt of emails). And then we would move on to the next experience. FastSpring was the last one we tried – it is so much better than the others; there is no comparison. It's almost as if whoever designed it had actually developed and sold software in a previous life, and knew exactly what a customer like us wants and needs to do.

So far it appears FastSpring has increased my completed orders by around 10-20% over [the service I used previously]. My non-USA orders appear to be up to about 1/3 of my sales. I think this is where the most increase has occurred as [the service I used previously] made it difficult for non-USA customers—and they had marked many completed orders as "fraudulent" and refunded them.

Just wanted to tell you guys that you have by far the best e-Commerce product we have ever used. Your product is very easy-to-use, extremely flexible and modern. Keep up the great work.

Working with Fastspring has been an incredible joy. In this age of impersonal transactions, the fact that one can actually communicate with caring individuals, who seem to love their job and their company, is not only refreshing but sets Fastspring lightyears ahead of the competition. Well done.

If you keep up the support as good as for now I'm sure that a lot of [software firms] will change to FastSpring. I'm really surprised; I know you offered – but I see that you really deliver.

Thanks to the awesome assistance of both Shawn and Ken, I have completed the set-up of my order pages. I just have to comment on how impressed I have been with the "over the top" customer service and support your team has provided me. There was no question too simple or customization too complex that either Shawn or Ken did not look into to see if it could be accommodated. In addition, I have appreciated the fast response turnaround to my emails. As I prepare to launch my new start-up, I now have a high benchmark for how a superior customer service and support team operates. I can only strive to provide the same level of exceptional service your company does.

Support is the best I've ever had from any company in any industry. Prompt knowledgeable answers in less than 2 hours. By the way now (this is) a great comment on the FastSpring service, Ken was able to clear this up for me within about an hour of my initial request & that's including me going back several times with supplemental questions.

Very easy to set up, you can have an ecommerce site up and running in less than a day you get the ability to sell internationally. In other words, it’s a one-stop-shop for ecommerce particularly suited for software vendors and startups.

Our conversion rate is now 40% higher than before we started using the FastSpring platform.

Thanks to FastSpring's ability to localize payments, customers are now seeing the price presented in their own currency, with clear information about the prevailing rate of Taxation. This has inspired buyer confidence, significantly reducing our cart abandonment rate by estimated 30%.

We met our business goals by improving back office efficiencies. We are 100% automated.

We chose FastSpring as our new ecommerce platform because they showed us that they wanted to be our ecommerce partner and we are happy we did. Since launching our FastSpring ecommerce store, we have seen a 40% increase in conversion rate. And furthermore, we have reduced the resources needed to maintain and operate our ecommerce business by 50%. It’s been a win-win all around.

We were focused on not only finding an ecommerce platform that worked but also building a relationship and partnership which I believe is very important. You don’t want to buy something and then be alone. You need a good partnership. In the end, we picked FastSpring because they showed us they wanted to be a true partner.
