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!
Cannot rate these guys highly enough! A lot of companies could learn a lot from Clerk.io!
There are the companies that you have to work with, and then there are those who you love to work with. Clerk.io definitely belongs to the latter.
We've used Clerk.io since the beginning of 2015 and there is no question about it, Clerk.io is one of our secret weapons. Their support, service and know-how continue to amaze us!
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.
It's automated, increases revenue and the support is fantastic. I am a fan!
How does Clerk.io measure usage?
Not all API requests are of equal value - so why should you pay the same for each? At Clerk.io we try to align our pricing with the actual value we create for you. For most use cases "1 API request = 1 usage" but some simple API requests are only counted as 0.5 or 0.2 in usage. Some requests like product updates and 0-results are always completely free. Thus your usage is always lower than the total amount of API requests you make to us.
Where can I see my usage?
You can at any time see your historic and predicted usage at your companys' Usage Dashboard on my.clerk.io. We store all historic usage so you have a complete account of how it has developed and we also forecast your current monthly usage so there is full transparency.
How can I know if Clerk.io is performing?
From day one, you will have access to our dashboard, which drills down not only how much is sold through Clerk.io, but also how we affect your key KPIs, such as basket size, avg. order value and conversion rate.
Before you start we can even give you a full demo of how Clerk.io will perform on your won data so you can compare Clerk.io side-by-side with your existing setup.
Can I run multiple stores?
Yes. Your plan is based on the combined usage on all of your sites. We don't charge you for having additional sites. Actually, it's beneficial, since you get a lower unit cost price.
Can I use my own design?
Yes. Results from Clerk.io can be styled just the way you like and integrated in any way you like. When rendered they are just as much a part of your site as any other element.
Can I get a development environment?
Yes. In fact, many of our clients do that. You can simply use a store as a development environment. That way you can test anything before releasing it to your live store.
What if I go over my plan limits?
With us you just pay for what you use so your pricing will follow your usage. That's it. Your shop will continue to function as usual, you will still be able to access your account and all your data will still be available to you.
Do I need to pay extra for premium support?
No! All plans come with full 5-star support! You can contact us by chat, email, phone within support hours which is Monday to Friday 09:00 - 17:00 CET. We'll pick up the phone when you call and answer email or chat right away.
