Smart Flat Rate Shipping adds one shipping method to WooCommerce that offers as many flat-rate options as you configure. Each option has a fee, optional conditions, and a priority.

What you can do

• Fixed fee, optional per-item fee, optional “free shipping from” subtotal.
• Conditions: cart subtotal, cart quantity, products, product categories, destination country, state and postcode.
• AND inside a group, OR between groups, with a readable summary in the list.
• Shipping simulator: test a sample cart and destination without a real cart, order, payment or stock change. It uses the same pricing engine as checkout.
• Diagnostics: environment checks and an optional, bounded log that explains why a method matched or not.
• Works with WooCommerce shipping zones, taxes, multiple packages and native shipping methods. It never hides or changes other methods.
• Documentation: step-by-step guides for every screen and condition.

How rates are calculated

Cost = base fee + per-item fee x chargeable units. If the eligible subtotal reaches the free-shipping threshold, the cost is 0.

• Subtotals exclude tax. Coupon discounts are deducted by default (a setting lets you ignore them).
• Eligible items: for the first matching condition group, the items selected by its “contains any of” product/category conditions; every item if the group has none.
• Per-item fees count all cart units or only eligible units, as chosen per method.
• Methods are independent: every matching method is offered, none hides another, and prices are never added together.
• Location conditions need the customer’s address. Until a value is entered, a location condition does not match (also “is not one of”), so a rate is never shown to the wrong place.
