CartMend Checkout Fees & COD Surcharge for WooCommerce

Charge a Cash on Delivery (COD) fee — or any payment-method surcharge or discount — in 60 seconds. No code. No bloat.

Works on classic and block checkout.

WooCommerce has no built-in way to add a fee when a customer picks a specific payment method. If you offer Cash on Delivery you absorb the courier collection fee and the cost of returned parcels; if you take cards you absorb the processor fee. This plugin lets you pass that cost on — or reward prepaid customers with a discount — cleanly, in the checkout totals.

It does one thing well: when the customer selects the payment method you choose, it adds your fee (or discount) to the order.

Features

• One flat fee or discount (negative amount) when a chosen gateway is selected

• Pick which payment method triggers it (any registered gateway)

• Custom, customer-facing fee label

• Taxable / non-taxable toggle

• Works on classic and block checkout, with the fee updating live when the shopper switches payment method

• Fee shows on checkout totals, order confirmation, customer email and the admin order screen

• One clean WooCommerce settings tab — no extra admin menu clutter

• Lightweight: no jQuery; a tiny script loads only on the checkout page, everything else is server-side PHP

• HPOS (High-Performance Order Storage) compatible

Some countries and US states restrict surcharging card payments. Check your local rules before adding a fee to card gateways.
