Opus Cart Upsell Cart Drawer

I recently experienced an issue where discounts were not showing correctly in the cart when adding bulk products from my custom-built page. Even though it happened right before Black Friday — one of the busiest times of the year — the Opus Cart support team responded incredibly fast and resolved the problem quickly.

I’m genuinely impressed with their efficiency, professionalism, and willingness to help, even under pressure.

Excellent support — highly recommended!

Vivian from Opus Cart Upsell has been absolutely amazing! She went above and beyond to help me set up and customize the app to fit my store perfectly. Her responses were fast, clear, and super friendly — she made the whole process smooth and stress-free.

The app itself works great and has already improved our upsell conversions, but what really stands out is the quality of support. Having someone as attentive and knowledgeable as Vivian makes a huge difference. Highly recommend both the app and the team behind it!

Amazing App & Excellent Support!

Very responsive and professional team! They quickly implemented my suggestion, and the new feature works perfectly on my website. I really appreciate their efficiency and dedication highly recommend!

Application Parfaite et service client très réactif ! J’avais une idée précise de la barre dans le panier et ils ont réalisé exactement ce que je voulais en un temps record !
Ça marche parfaitement et ça a augmenté mes ventes de façon spectaculaire ! Merci

I’ve had such a great experience with the Opus app, but what really impressed me the most was the amazing support team. A huge thank you to LULLA and KHANG – they immediately understood where the problem was and patiently guided me through it.

The issue turned out to be on my side (I wasn’t logged in with the correct email ), but they were so kind and patient while waiting for me to sort that out. Once I gave them access, they fixed everything super quickly.

What I loved most was the speed and ease of communication – no unnecessary formalities or endless emails. Just a respectful, friendly, and straight-to-the-point approach that made the whole process smooth and stress-free.

I honestly couldn’t be happier with the support I received – it makes me even more confident in using Opus long-term!

I've tested multiple cart drawer apps on the market and Opus offers the best performance-customizasion-support-price ratio.

There are a wide variaty of features offered, with custom cart display settings based on customer tags, multilingual, auto-discounts and on top, customer support is super responsive, flexible, friendly and finds solutions to all sort of requests.

Really happy with it!

Thank you, Beeter, for all your help in the past weeks. :)

This app is super useful and truly the best in the market! The Opus Cart has significantly improved our store's conversion rates and the slide cart feature works flawlessly.

I want to give special recognition to the support team - Vivian, Lulla, and Beeter have been absolutely exceptional. They responded quickly to all my questions, were incredibly patient in walking me through the setup process, and went above and beyond to ensure everything was configured perfectly for our store.

Their professionalism and dedication to customer success really sets this app apart. Highly recommend both the app and their amazing support team!

This app completely changed how my store handles pre-purchase offers. The cart drawer looks polished, customers interact with it far more than before, and the upsell suggestions feel natural rather than pushy. Within days, I saw more add-to-carts and a noticeable lift in average order value. Definitely one of the most effective updates I’ve made.

So far has been a great app! Had some requests for changes, and the team have been super helpful in getting them done.
