What clients say

I switched my booking website from Square to iBooker about a month ago, and it's been one of the best decisions I've made for my business. The website is significantly more customizable, integrates perfectly with Square Appointments, and solved the conversion tracking issues I was having with Google Ads and Meta. The biggest highlight has been the customer support. The founder has been incredibly responsive, has answered every question I've had, and has even taken feature suggestions seriously.

I worked with Yaroslav. He completely rebuilt our Google Tag Manager setup and made tracking reliable across every page and form. He also set up cross-domain tracking, synced data between GA4, Google Ads and our CRM, and built clear, useful Looker Studio dashboards. I highly recommend working with him.

It was a pleasure working with Yaroslav on a digital marketing project. He set up the ad campaigns, optimised SEO and organised the project into a clear, scalable structure. Yaroslav is proactive, detail-oriented and reliable. I gladly recommend him for SEO, paid traffic and website optimisation.

I rarely leave reviews online but iBooker.online has been nothing short of extraordinary. We have been using Square and were unable to obtain any analytics data for our Google Ads, and that is the main reason why we switched to iBooker. The website widget has also been a game changer for direct booking on our website. I also have to give a shout out to the team and developers, who are among the most responsive and capable I have seen, with adjustments made often the same day.

One of the most responsive software companies that I have ever dealt with in my career. They are quite flexible and take my recommendations seriously. Really a pleasure to work with, not to mention their pricing is very reasonable.

iBooker has been a game-changer for tracking. The onboarding was smooth, the support team is quick and genuinely helpful, and you never get stuck waiting around. I even spoke with the founder, who clearly cares about the product and customer experience. If you're using Square and want real visibility into your Google and Facebook spend, iBooker is absolutely worth a try.

I have a great experience working with iBooker. I have a nail studio and this widget helps us understand which ad sources are most effective for us. Support works so fast. No issues at all.
