ResinViet review for Ⓩ ZoTek COD Form & Upsells

May 29, 2026

I highly recommend Zotek COD Form & Upsell. The app works smoothly and provides a stable COD checkout experience. The upsell features are very useful and easy to configure, helping increase our average order value. What I really like is the integration with Zotek Pixel, which allows us to track COD events accurately across Facebook Pixel and TikTok Pixel. This is extremely important for optimizing ads and measuring campaign performance correctly. I also contacted their support team a few times, and they were very responsive and helpful. Overall, a great solution for Shopify stores running COD.
