Add the right fee to the right order, automatically.

Plusero - Extra Fees for WooCommerce lets you add a charge to an order when a condition you set is met. A cash on delivery surcharge. A small order fee. A packaging charge on fragile goods. A card processing percentage. You describe the rule once and the fee applies itself from then on.

It is free, complete on its own and made for any WooCommerce shop that wants fair, visible fees without code snippets. Nothing is limited, locked, trial based or time restricted, and there is no limit on how many fees you create.

What's new in 1.2.0 (October 15, 2026)

• Find a fee faster. The fee list can be narrowed to All, Active or Inactive fees, each with a count, and to the fees charged in one place: product, cart, checkout, shipping or payment.
• Plays nicely with Pro. While the Pro edition is active this plugin stays idle and a note on the Plugins screen says it can be deactivated, instead of switching itself off.
• Security hardening. Posted settings and fee data are cleaned as they are read, and the fee being edited reaches the builder through a properly enqueued script.
• Your fees survive a clean up. Deleting the plugin keeps the shared fees while the Pro edition is still installed.
• Tested with the latest versions. Checked with WordPress 7.1.3 and WooCommerce 11.2.1.

Five places a fee can apply

• Product. Charged when a matching product is in the cart, such as packaging on fragile goods. A percentage product fee is taken from the products it matches, not from the whole basket.
• Cart. Charged on the cart as a whole, such as a small order fee.
• Checkout. Charged on who the customer is and where they are.
• Shipping. Charged on the shipping method the customer picked.
• Payment. Charged on the payment gateway the customer picked, such as a cash on delivery surcharge.

Decide when a fee applies

Eight conditions cover the rules most shops need:

• The basket. Cart subtotal and total quantity.
• The products. A chosen product or variation, or a product category.
• The customer. Customer role, with visitors who are not logged in counted as Guest.
• Where it is going. Billing country.
• What they chose at checkout. Payment method and shipping method.

Combine conditions so that either all of them must match, or any one of them is enough. Leave the conditions empty to charge a fee on every order.

Work out the amount

• Fixed amount. A flat charge, the same on every order.
• Percentage. A share of the cart subtotal, with or without tax, or of the matching products on a product fee.
• Limits. Set a smallest and a largest amount, which keeps a percentage fee sensible on very large orders.
• Rounding. Two decimals, up to a whole number, the nearest 0.05, or no rounding.
• Tax. Mark a fee taxable and pick which tax class it uses. WooCommerce then treats it like any other taxable line in your tax reports.

A builder that explains itself

Fees are built through a short guided flow that asks five plain questions: where the fee applies, when it should be charged, how much it should be, what customers should see, and whether it reads correctly. Every answer is shown back to you as a sentence before you save, so you know exactly what you built.

• Customer facing wording. Give each fee a label, a description shown under the fee amount in the classic cart and checkout totals, and a tooltip.
• Order and status. Decide the order fees are worked out and displayed in, switch a fee off without deleting it, or duplicate one as the starting point for another.
• A tidy fee list. See where each fee applies, what it charges and whether it is active, and narrow the list to active or inactive fees or to one location.
• Shop wide settings. Show or hide tooltips and descriptions, and hide fees that come to zero rather than showing a blank line.

Fees that react to checkout

A payment fee reads the gateway the customer selected and recalculates the moment they switch, so a cash on delivery surcharge appears and disappears as they change their mind. A shipping fee does the same with the shipping method they chose. This works on the classic checkout and on the block checkout.

Works where WooCommerce works

• Everywhere an order goes. Fees are added through the standard WooCommerce cart fee hook, so they appear in the cart, the checkout, the order, the confirmation email and PDF invoices with no extra setup.
• Classic and block checkout. The classic cart and checkout, the block cart and checkout, and the Store API all show the same totals.
• High Performance Order Storage is supported.
• WPML and Polylang. Fee labels, descriptions and tooltips are registered automatically when you save a fee, so they can be translated alongside the rest of your shop.

Built in documentation

Every option is explained inside your dashboard, under Plusero Fees, Documentation: what each condition means, what each calculation does, and what to check when a fee is not showing. You never have to leave your site to look something up.

For developers

The plugin is built around filters. Register a condition with plusero_ef_conditions and answer it with plusero_ef_evaluate_condition. Register a calculation with plusero_ef_methods and work it out with plusero_ef_calculate_custom. More than sixty actions and filters run through the code, and the main extension points are documented under Plusero Fees, Documentation, For developers.

Privacy

This plugin does not connect to any external service. It makes no remote requests and sends no data anywhere. Everything it stores stays in your own database.

FAQ

My fee is not showing in the cart?
Check three things in order: is the fee active in the fee list, does every condition match the cart you are testing with, and does the amount come to something above zero, since fees that work out to nothing are hidden by default.

Can I charge a fee only for cash on delivery?
Yes. Add a fee, choose Payment as the location, add a payment method condition set to your cash on delivery gateway, and set the amount. The fee appears as soon as the customer picks that gateway.

Where does the fee description appear?
Under the fee amount in the classic cart and checkout totals, as a short line in smaller text. The block cart and checkout draw their own totals and do not show it. You can turn descriptions off for the whole shop under Plusero Fees, Settings.

Can I charge different amounts at different order sizes?
Yes. Build one fee per band and give each a cart subtotal condition covering its range.

Will deleting the plugin remove my fees?
Only if you ask it to. The setting to remove all fees and settings when the plugin is deleted is off by default, so your fees survive a deactivate, a reactivate and an update.

Plusero Pro

Plusero Pro includes everything in this plugin and adds:

• Ten more conditions: cart weight, number of different items, product tag, logged in, orders placed before, billing state, billing postcode, shipping country, day of the week and coupon used
