The usage fees are ridiculous, and I didn't noticed until I just saw that I was charged $115 when only a single $25 order came via their app. In all, in 2025, they charged me $720 for 4 small pre-orders. They will charge you based on store volume that has nothing to do with them, even when all the volume is from third party marketplace integrations with Shopify where it wouldn't be possible to use this app in any capacity. Outrageous fees. Stay away from this app if you have high volume that doesn't have anything to do with pre-orders.

What can I say from install to now soon to be uninstall - problems! Add to cart function does not work - on my site The ap removed add to cart button from my site I now have to re-upload and publish multiple SKU's What I can say is the support team tried to help as much as possible and where incredibly diligent helping for over 4 hours - they just couldn't fix the button issues or get the ap to work correctly.

Sudden charges after being installed and used for 3 months without charge Support refuse to say there is an issue. Send me to shopify for help but shopify say it is the apps issue I would not recommend this app dev at all after my experience ***Update*** 2 Months later after a lot of back and forth emails and live chats between shopify and kaktus i eventually got my refund. It took a huge effort to get this back. Then once received Kaktus then kept requesting i alter my review. So here is my updated review: I would not recommend this app at all after my experience

Horrible, does not load in properly half the time leading to regular checkouts and charge backs and randomly just stopped working after a few days. Customer support was pretty much worthless, use any other preorder app...

Was trying out new pre-order apps and we ended up going live with this one - it was easy set up and had a fast loading time on our store. Just when I went to announce on our social media, we did a double check and suddenly the widget was gone from the product page and the app was experiencing a server error - could not even open the app. Decided to give it some time and tried it again. Server came back maybe 20 minutes later and we went live. About two hours later we were notified by a customer trying to check out that the widget was gone and there was not an option to preorder and we saw that the server was done again. Bad first impression and definitely upsetting. We had to uninstall the same night and find an alternative so we wouldn't lose sales :/

Charges you for all orders through your store, even if they didn't use the platform. 65 pre-orders cost us hundreds of dollars in usage fees. Also, terrible support - passes blame back to Shopify when the pre-orders don't complete the second payment. Awful app, awful people.

Wonderful customer service that helped us fix a small issue quickly. This app was easy to use and we were able to create a pre-order for some of our seasonal and holiday products. Highly recommend!

Stellar app + stellar service = winning combination! The app is a lifesaver as I had some issues with a different preorder app that crashed my site thus I found my way to greener pastures with Kaktus!!! This is sooooo user-friendly, easy to setup in very little steps and with much ease. The interface is easy to handle and really only takes about 3-5 minutes to setup. I had a few custom design/functionality questions and with the simple use of the chat interface, I was up and running in under 3 minutes!! A COMPLETELY different experience from the previous app I installed and quickly uninstalled.... this one is definitely a keeper! Keep up the great work and thanks for supporting us small business owners!
