Good Tool With Good Support

Their support teams and chat are generally very very helpful at rectifying your issues.

We are on a bespoke platform, so things aren't as plug in and play for us as they can be for other Clerk.io users.

There have been teething problems in the past and it was a lot of work getting Clerk to work as well as it probably can do for most people on our website.

We use recommendation sliders and the search function.

On the whole it is a great tool, it tracks pretty accurately, and the data it gives is very useful

There are some functions and things I wish it could do, which would help me more and I think would be fairer billings wise, but those things won't change.

Misleading sales promises, poor communication and billing without delivery

Our experience with Clerk has been extremely disappointing and frankly unacceptable.

The solution was very clearly sold to us as a simple “plug-and-play” setup that would be live within days. This urgency was also used during the sales process to push for a quick signature. In reality, weeks passed after the contract start date without the solution being live or delivering any value.

Despite this, we were charged from day one.

Throughout the onboarding period, communication was inconsistent and largely reactive. We repeatedly had to chase updates, correct issues ourselves and ask for basic clarity on timelines and progress. At one point, the person responsible for the implementation was out of office without any proper handover or proactive communication, which further delayed everything.

Most concerning was the clear gap between what was verbally promised during the sales process and what was later referred to as the “standard implementation timeline.” Expectations were simply not set honestly from the beginning.

When we finally chose to terminate the collaboration due to lack of delivery, our emails regarding termination and previously agreed conditions were effectively ignored. Instead of acknowledging the situation and working towards a fair solution, the focus remained on defending the billing and pushing us to go live — even after we had clearly communicated that we no longer wished to proceed.

Charging customers for a product that is not operational, failing to communicate transparently, and then disregarding termination requests is not how professional SaaS partnerships should work.

Based on this experience, we strongly advise others to be very cautious. We would not recommend Clerk.

Excellent Search Solution with Outstanding Support

Clerk is a very powerful and reliable search solution that significantly improves the user experience in our shop. The search results are highly relevant and the system performs extremely well even with complex product data and large assortments.

What we especially appreciate is the high level of flexibility and customization. Clerk can be tailored very precisely to individual business needs, allowing fine-grained control over search behavior, rankings, and merchandising strategies.

In addition, the support team deserves special mention. They are very responsive, knowledgeable, and genuinely helpful. Questions are answered quickly and solutions are explained clearly, making collaboration efficient and pleasant.

Overall, Clerk is an excellent choice for anyone looking for a modern, intelligent, and highly customizable search solution backed by outstanding support.

Good software

I need to be honest, I was at first angry as the software did not function as I wanted to be. But in the end because of Wagner and Matilda it functions good.

I want to thank you for your help.

Charged for months despite never going live – poor cancellation experience

Awful experience please avoid.

We signed up to use Clerk.io Search and Recommendations to trial the service on 12th December 2025 (Shopify). Unfortunately, there were early technical issues between Clerk.io’s system and our Shopify category structure, meaning we couldn’t complete setup before the Christmas and New Year period.

When we returned after the holidays, we decided the platform wasn’t going to be suitable for our needs and requested to cancel. We had never gone live with Clerk.io, and the service had not been fully implemented on our store.

However, Clerk.io charged £198 on 12th December, and then took another £198 on 12th January, despite the service never being live. When I questioned this, I was told that cancellation required 30 days’ notice, and that even after cancelling they would take another £198 on 12th February, with the contract ending 12th March.

Overall, this left us paying for multiple months of a service we did not end up using, and the customer service experience around billing and cancellation was very disappointing.

If you’re considering Clerk.io, I strongly recommend getting the cancellation terms and billing dates in writing, and making sure you’re fully confident it will work with your Shopify structure before signing up.

Hi Christopher,

Thank you for taking the time to share your experience. We’re genuinely sorry to hear that Clerk.io did not end up being the right fit for your store, and that the cancellation process felt disappointing.

When you sign up for a Clerk.io subscription, billing starts from the contract start date. This is because that period is used to begin the implementation of Clerk.io on your website. The implementation itself has no additional cost, and an implementation specialist is assigned to support and work on your setup during this time, even if the solution does not ultimately go live.

Regarding cancellation, our subscriptions require one month’s notice, which is outlined in our terms of service: https://trust.clerk.io/terms. This notice period applies regardless of whether the service has gone live, as resources and support are allocated from the start of the contract.

That said, we understand how frustrating this can feel, especially when a solution does not progress as expected due to technical constraints. Your feedback is valuable and helps us improve how clearly we communicate billing and cancellation terms during onboarding.

If you would like us to review your case further or have any outstanding questions, please do not hesitate to reach out to us directly at support@clerk.io.

Best regards,
Clerk.io Team

Delivered on Time Despite a Tight Deadline

Even though the deadline was tight and there were some unexpected challenges along the way, Clerk delivered on time as agreed. Their team has been professional, responsive, and always ready to help whenever needed. The implementation process went smoothly, and I’m looking forward to continuing the collaboration in the future.

Abysmal customer service.

Abysmal customer service.

You can tell how good a company is when things go wrong.

I was moving platforms and wanted to close my account until my new website was up and running then maybe I'd come back again to clerk.io

They made me book and online chat wit them to try and talk me into staying despite it being "me" not "them"

I was impossible to just close the account and so surprise surprise they took another payment at month end.

They then argued saying I hadn't cancelled - despite my having many emails where I literally said "close my account".

I'm now having to pursue through my credit card company to get my money back as a fraudulent transaction

When you're doing business with a company who won't fix their mistake unless you report them as "fraudulent", I'd respetfully suggest they are not worth dealing with
