WooCommerce Checkout Fees plugins (often shipped as part of "WooCommerce Payment Gateway Based Fees" or "WC Checkout Fees" by various authors) let you attach a flat or percentage fee per payment gateway, country, shipping method, or cart total. The default admin is usually a settings tab under WooCommerce, plus the fee showing up as a line on each order. There is no list view that says "Stripe surcharge fired on 318 orders this month, generating $1,272."

SleekView reads gateway fee rules from wp_options (typically a key like wc_checkout_fees_settings) and joins each applied fee back to its order through wc_orders on HPOS or shop_order on legacy. A per-gateway audit view surfaces order id, gateway, fee amount, customer email, and date, all sortable and filterable. A kanban grouped by gateway makes the gateway mix obvious for finance.

Inline edits update the plugin's config option with conflict detection, so disabling the COD surcharge, raising a Stripe percentage, or scoping a rule to a country list happens from the same screen as the audit. Refunds get the right treatment because SleekView joins shop_order_refund children (legacy) or the HPOS refund parent-id link, so the per-gateway revenue figure stays honest.

Gateway surcharges exist because payment-processor fees vary, sometimes by a lot. A COD order costs the merchant the bank-deposit fee; a Stripe order costs roughly 1.4 to 2.9 percent plus a fixed amount; a PayPal order costs similar with cross-border adjustments; an iDEAL order costs almost nothing. Merchants that recover those costs with a checkout fee plugin are right to do so, but they almost never audit the rules afterwards.

The default admin makes the audit hard: per-gateway revenue lives in wc_orders_meta but never shows on the Orders screen, refunds offset the revenue but no view subtracts them, and toggling a rule means opening the settings tab. SleekView turns the audit into a saved view: per-gateway order count, fee revenue, refund-adjusted figure, all sortable and filterable. Same database, same hooks, dramatically less spreadsheet plumbing for the finance lead who has to justify keeping or killing each surcharge.
