Verified reviews from the Shopify App Store.
★★★★★
“We chose this app as it has no limits of interactions like many others out there.”
★★★★★
“This Shopify app makes customizing payment/shipping methods and adding checkout upsells a breeze. The customer service is excellent too…”
★★★★★
“Such a great app! Meera was a huge help from start to finish. She responded super quickly and was really friendly throughout the whole conversation, which made the process easy and stress-free. We needed a few adjustments made, and she walked us through everything clearly and got it all sorted without any hassle. The support was genuinely top notch — responsive, patient, and focused on actually solving our problem rather than giving canned answers. It's reassuring to know that help is there and handled so well when you need it. Easy to recommend for anyone who values fast, reliable, and friendly support.”
