App is super cool and recommended from a web developer. I had a minor issue with the alignment, messaged the support function, it was sorted in sub 5 minutes. App is cool and reliable! Sneha is awesome!

STOQ has been an awesome addition to our Shopify stack. The app is clean, intuitive, and does exactly what we need without slowing down our site or overcomplicating workflows. Setup was smooth, and the features have already made a noticeable impact on our operations. Huge shoutout to Vishu on their team. Absolute rockstar. Super responsive, knowledgeable, and genuinely invested in making sure everything worked perfectly for us. Support like that makes all the difference. Highly recommend STOQ to any brand looking for a reliable, well built Shopify app with top tier customer service.
