Payment Gateway Surcharge & Fees for WooCommerce lets you recoup card, COD, and BNPL processing costs instead of quietly eating them on every order. It hooks into woocommerce_cart_calculate_fees to inject a named fee line — percentage or fixed, per payment method — that updates live as the shopper switches gateways on the checkout page, so the cost is shown transparently and is never a post-purchase surprise.

This is a build-to-order plugin, not an instant marketplace download. After purchase, ECOSIRE configures the surcharge rules to your gateways (Stripe, PayPal, COD, Klarna, Tabby, or whatever you run), installs the plugin on your WordPress site, and supports it. You tell us your fee structure; we encode it.

Fee logic is tax-aware: surcharges can be added before or after WooCommerce tax, flagged taxable/none, and mapped to the correct tax class so your accounting and invoices stay clean. Min/max caps stop a percentage fee from punishing a large basket or being trivial on a small one. Conditional rules trigger fees by cart subtotal, shipping country, shipping zone, product, or user role — useful for charging COD fees only in specific regions. You can also flip the logic into an incentive: a discount line for shoppers who pick your cheapest-to-process method, nudging them off expensive rails.

It is built for modern WooCommerce: HPOS (High-Performance Order Storage / custom order tables) compatible, the fee persists into order item meta and the REST API order payload, and admin configuration lives in a dedicated wp-admin settings screen under WooCommerce. WPML and multisite support is available on request. Every label is translatable so the surcharge reads correctly in your customers' language.
