Paylock – COD Discount Control

Paylock, officially listed on the Shopify App Store as Paylock – COD Discount Control, is a Shopify app in the Checkout - Other category. Paylock lets you control which discount codes should not be used with Cash on Delivery orders. If a restricted discount is applied and the customer selects Cash on Delivery, Paylock blocks checkout and shows a clear message explaining that the discount is not available for COD orders. This helps prevent misuse of influencer codes, promotional discounts etc on COD payments. Paylock runs directly in Shopify Checkout using Checkout Extensions, so it works without modifying your theme code.

Paylock offers a free plan and 2 paid plans starting at $4/month and going up to $9.99/month. The free plan includes Block COD for 1 discount code, Rule automatically expires after 14 days, Default checkout block message, and Works directly in Shopify Checkout. The paid plans unlock advanced features beyond what's available on the free tier.

Paylock does not currently carry Shopify's Built for Shopify badge. The badge is awarded to apps that meet Shopify's published standards for performance, ease of use, and merchant value — many high-quality apps operate without it.

Merchants commonly compare Paylock with Payment Rules Hide PaymentHero, Magical Fee Surcharge + Tariff, EcoCart Green Protection, and Puco Checkout Rules. Each alternative covers a similar use case but differs on pricing model, integration depth, and the specific themes merchants praise in reviews — see the alternatives section above for a side-by-side.
