Great app and exceptional customer service. Ramon is a great help and replies back super fast with any questions I have.

Just Say Tees

Qstomizer is awesome! I tried several apps before I found this one. I wanted something that my customers could use to design their own shirts and other products, and I didn't want something that was super complicated. Of all the apps that I tried out, this is the easiest to use. I can keep my current supplier which I have already developed a relationship with. Ramon helped me to get my first product up and running and now I am able to get started much sooner than I thought. I would highly recommend this app and it is definitely worth the price, and they have great customer service.

Don't worry about looking anywhere else other than Qstomizer. Easy to use and Ramon was a pleasure to work with.

Great app waiting long time for such a excellent app also support is great


such a great app with great assistance from the App developer. When I downloaded this app, it wasnt exactly compatible with my website needs but when I contacted them about it, they tailored the App for me that lines up with what I needed. Such a great service and a great app!! Thanks Ramon for always being so helpful and for making sure that I get the right app for my website needs. :)

Ramon is always there to help you out. This truly is a 5* support and a great app.


This is the first time I ever write a bad review about any product online. I felt scammed by this company. I paid Ramon USD250 on August 2017 for the installation of the app on my products and another USD1165 on September 2017 to add and setup the pre-made templates that we created, add Google fonts, colors etc. On our agreement, he should be able to finish the works within 15 business days. But he done it little by little and still not yet finish. I kept on contacting him by email, took so long time to response and not really answering my questions. I have been paying for Professional Plan which suppose to have priority support. I needed to cancel several marketing campaigns because the app is not yet configured properly. I patiently waited because while my business suffered a lot. The pre-made templates are very important on my store and none is added on my website. I even asked him lately to add partially so I can start with my campaign and he said he will do it in 2-3 weeks. But nothing is done after a month.

I finally gave up and cancelled my subscription. Then suddenly he sent me a message, just to tell me to activate the app again because he will add the fonts, after 6 moths! And how about the other pending jobs?

I asked for refund but of course, he never answer back!

By the way, I found a better app, with great support. It is called Zakeke.
