In addition to increasing sales in the webshop, Clerk.io also makes daily work much easier, as much of the work that took long before can now be automated - especially the automatic email recommendations makes a big difference for me.

Nothing but praise. We have been using Clerk.io for about a year now and there is ony praise to be given. Strong performance, excellent customer service and easy integration were key for our decision to switch to Clerk.io and we were not disappointed.
Oliver Rau

So powerful and so easy to work with as a developer. Clerk.io is a must have for any webshop. Recommended products based on visitor actions and a good search engine is the backbone of a good webshop and Clerk.io nails it!
Jeppe Skovsgaard Christensen

It's been a great boost to our webshop. Easy to use and install, last but not least: excellent support, very fast, very kind, very helpful, there's nothing that was not solved by them. Very highly recommended to everyone.
Noble House
Developers loves Clerk.io! It is one of the most useful tool to integrate search in my Customers' stores. It's a really nice experience to work with it, from the development to the next improvements. Intuitive GUI and the support team always have the solution to any needs.
Clerk.io provides this very unique combination of great products and great service - for a very reasonable price. Enabling non-techies to (intuitively) implement real-time personalizations in website, search and e-mail, I consider Clerk.io among the best SaaS-products I have ever used!
Daniel J. Friis

Clerk.io is a fantastic tool that really enhances the customer experience and drives sales. Support has always been excellent, and they're also proactive at suggesting improvements - thanks Domenico :)
Our developer who installed it has recommended it to several of his own customers... that's how good it is!

Kevin Ross

Great experience so far. I have used Clerk.io for different e-commerce and I could see a massive impact on the revenue. One more thing: customer support is super for real. I asked support to manage custom integration and they have been super!
Rosario Toscano
I have always been very exited about Clerk.io since the first contact back in 2014. It increased order size from first day and flexibility of the tool are brilliant.
Yesterday I was contacted by Dion because he saw some small improvements in the way I use their software and thank you very much for that world class service!

Mikael Hansen

Knowing Clerk.io from the developer side, integrating it in customer projects, advance in more customized solutions based on Clerk.io, all I can say is: It's an awesome product! It focuses on cutting edge technology and integrates nicely with every environment we yet used.
Christian Pohl
We have been using Clerk.io for well over a year now, for a large number of sites. Not only do they help improve conversion rates by providing a more accessible experience for our users, they can also prove this effect through data analysis, in their very impressive admin console. I would recommend them any day =)
Joakim Andersson

Just do it. Once you've tried Clerk.io you can't go back! I've been using Clerk on my web shop since March '17, and during the last 3 months we've seen a significant effect of this amazing tool. I'll give Clerk.io my very best recommendations to everyone working with commerce.
