COD King‑COD Fees & OTP Verify is a comprehensive app designed to streamline cash on delivery (COD) processes for merchants. The app enhances order verification by utilizing OTP or secure links via SMS and WhatsApp, significantly reducing the occurrence of fake orders and minimizing returns to origin (RTO), thereby cutting shipping costs. It offers flexibility in payment methods by allowing merchants to toggle the visibility of COD options based on specific criteria such as country, zip code, product, or cart value. Additionally, the app facilitates the imposition of extra fees for COD transactions, encouraging customers to opt for prepaid methods through strategic discounts. To further drive sales, it sends abandoned cart messages, urging potential buyers to complete their transactions. This feature-packed application is particularly beneficial in optimizing sales and ensuring the authenticity of COD orders, making it an indispensable tool for businesses reliant on COD.
