As a B2B company, we wanted shopping carts to be saved for 90 days instead of 30 days. We submitted a request to Casper, and after 5 days we received confirmation that this had been implemented. Our customers, who sometimes take several days to complete an order, are very satisfied that they can now continue working on their order across different devices.
Casper nous sauve des ventes ! Appli fiable et très efficace. Je recommande vivement, et le support est très professionnel et réactif
We consistently have an excellent experience with this app’s support team. Anytime we run into an issue or have a question, we receive a response almost immediately. Every concern is resolved or answered within one business day without fail. Truly outstanding service and support—we couldn’t ask for better!
Responsive developer. Product works well and fills our needs.
This app has been great for our store! Our sales team loves the ability to review and edit carts for their accounts. Clement is also super helpful and speedy with helping to fix issues. (we have only had 1 issue). Highly recommend this app!
This app is the perfect solution for our customers who are placing large orders and spending several days building their cart over multiple devices. I had a few questions and Clément was very helpful and responsive in addressing those. Thank you!
This app is a game-changer - well-priced, incredibly effective, and solves a major shortcoming in Shopify’s native functionality. Since implementing it, we've seen a significant boost in customer satisfaction. Clément is highly responsive and has even implemented new features based on our feedback. Couldn't recommend it more - truly a 10/10 experience!
Such a simple solution to such a silly Shopify limitation. Incredibly easy to install and get going. Carts are now syncing across multiple devices, including items with line item properties.
