OTP ‑ CoD Order Verification vs Subunofor Shopify (2026)
Both OTP ‑ CoD Order Verification and Subuno share a perfect 5/5 rating with 4 reviews as of 2026, but they address fundamentally different aspects of fraud prevention for Shopify merchants. OTP ‑ CoD Order Verification focuses on reducing losses specifically from Cash on Delivery (CoD) orders. It achieves this by verifying the order with the customer via WhatsApp, SMS, or Email using a One-Time Password (OTP) system. This aims to decrease Return To Origin (RTO) rates and the costs associated with fake orders. Its key strength lies in its ease of setup with built-in Shopify OTP verification and its geographical support, notably in regions where CoD is prevalent (India, Pakistan, Philippines, Egypt). Its target audience is merchants heavily reliant on CoD, especially in emerging markets. Subuno, on the other hand, provides a rules-based fraud prevention platform designed to combat credit card fraud and chargebacks. It offers customizable fraud checks, automated order screening, and advanced data analytics to flag, hold, or cancel suspicious orders before fulfillment. Subuno aims to provide an additional layer of protection for merchants' existing fraud prevention processes, without requiring any coding knowledge. Its strength is in its comprehensive fraud detection capabilities, including over 15 manual review tools and integration with third-party data analytics. Its target audience is merchants processing a significant volume of credit card transactions who require a flexible and robust system to minimize fraud losses.

Our Verdict
The choice between OTP ‑ CoD Order Verification and Subuno hinges entirely on the specific fraud challenges a merchant faces. If the primary concern is high RTO rates and losses due to fraudulent Cash on Delivery orders, particularly in regions like India or Pakistan, OTP ‑ CoD Order Verification is the clear choice.

However, if the main concern is credit card fraud and chargebacks, especially when processing a high volume of online transactions, Subuno is the more appropriate solution. Its rules-based engine, automated screening, and advanced data analytics provide a comprehensive approach to identifying and preventing fraudulent transactions before they impact the business. Merchants could, theoretically, use both apps for overlapping coverage, but their focuses are fairly distinct.
