Great app and very helpful support. I am still trying to resolve an issue caused by a third-party app. The issue is not yet resolved, but the support is so friendly and responsive and really willing to help. Also this issue has nothing to do with their app themselve. The app works like a charme, doing exactly what it should do!

Outstanding Support – Huge Thanks to Katie & Lulla! The app itself is super intuitive and does exactly what it promises — but what really stood out to me today was the exceptional support. I had a few custom implementation questions and both Katie and Lulla went above and beyond to help. They were fast, knowledgeable, and genuinely cared about solving my issue — not just giving a generic answer. It’s rare to find support this good, and they made the entire experience smooth and stress-free. Massive shoutout to Katie & Lulla — you two are rockstars! ✨ Highly recommended — both the app and the amazing team behind it.

One of the best support teams I've encountered on an app. Lulla was very helpful and even went out of their way to optimize my cart design to better match my store. 10/10.

The freedom to customize if better than any of the other cart apps I've tried. I had an excellent experience with Opus Carts support team. Very quick to respond, (faster than another popular app I was previously using) they helped me fix my exact problem, quickly making sure it's exactly how I wanted it. Best cart app I've tested.

Katie is so helpful! Thankyou

We asked Lulla for a custom code on the cart and she immediately got the dev team on it. Super fast and helpful support, really appreciated, especially at this hour. Amazing experience!

Thanks Vivian and Luila for the support!

Best Cart Drawer app you can find in the market right now

Great support with Alice and developper David

Best cart builder on shopify for sure, customer service really helpful (katie was great and real helpful, she deserves a raise) they actually help you for real

Merci beaucoup à Lulla ! Elle a réussi en quelques minutes a régler tous les soucis d'intégration que j'ai pu rencontrer, merci encore ! Et l'application est top et très complète !

Incredibly powerful app that's already generating more orders to my business. Their helpful supportive team have been amazing, in particular Vivian and Lulla to get the app fully integrated with my website. I have tested many cart apps and Opus is by far the best.

The support is amazing! Lulla and Mia really went out of their way to help us!

Lulla from the support tean was really helpful during the setup. I appreciate the quick reply and easy setup. We will test for CVR uplift with the app. Thank you.
