The shipping system in Craft Commerce is a way for shipping costs to be added to the cart.
In the Lite edition of Craft Commerce only two fixed shipping costs can be configured.
- A single fixed per order shipping cost
- A per item fixed shipping cost
These shipping cost settings can be updated in Commerce → Settings → General. These costs show up on every order made when running the Lite edition of Craft Commerce. You can set these to zero if no shipping costs are to be added to the order.
In the Pro edition of Commerce complex shipping rules including categories, zones and rules are available. The core components of the shipping system are:
- Shipping categories
- Shipping zones
- Shipping methods and rules
Shipping methods and rules are at the core of the shipping engine in the Pro edition of Craft Commerce. The shipping rules uses shipping categories, shipping zones, and additional order conditions to determine which shipping methods are available to the cart for your customer to select from.
Shipping categories are a way to identify different types of products to the shipping system.
When defining a product type, you can see the shipping categories that products of that type can belong to. When setting up individual products, an author can choose which shipping category from the available shipping categories that product belongs to.
You can manage which if a product type can use a shipping category when setting up the shipping category.
While setting up shipping rules, you have the ability to include those shipping categories into the rule’s conditions, and costs.
For example, you might set up a shipping rule which should not be available if the cart contains a product from a particular shipping category. In additional, a shipping rule can also return special prices for different categories of products within the cart.
Shipping zones are areas that you ship to. Shipping zones can be made up of one or more countries, or one or more states within those countries, as well as a zip code condition formula.
For example, you might make a zone for USA & Canada, and a different zone for the international countries you ship to.
These zones can then be used within the shipping rules as conditions to match on the customers shipping address.
Tax Zones are either country based (matching the shipping address to the list of countries in the zone) or state based (matching the shipping address to the list of states in the zone). In addition to country and state matching, an address can match zip code condition formula.
Zip code condition formula
A zip code condition formula is a short expression of logic that returns either
false. The expression syntax is powered by Twig.
Below are some examples of a zip code condition formula:
zipCode[0:2] == '60' or zipCode[0:2] == '70'
The zip code condition will match if the zip code has
70 as it’s first 2 characters.
zipCode in ['NG102', 'NG103', 'NG102']
The zip code condition will match if the zip code is any of the above values.
Shipping methods are the choices made available to the customer during checkout. For example, a shipping method might be called “Pickup”, “FedEx”, “USPS”, or “Express”.
You can name these shipping methods anything that makes sense to the customer. They do not need to be shipping company names, but usually indicate the delivery method. For example, you could have 2 shipping methods, one called “FedEx Standard” and “FedEx Overnight”.
Shipping methods contain a collection of shipping rules. This rules contain conditions and pricing logic for their shipping method they belong to.
Shipping rules belong to a shipping method. Each rule is checked one by one, in order, against the cart to see if it is a match. The first rule that matches the cart supplies the pricing to the shipping method. If no rules match the cart, then that shipping method is not available for the customer to select.
The matching of the shipping rules to the cart is based on the follow rules conditions:
Each shipping rule has a single zone. The shipping address of the cart is determined to be within or outside the rule’s shipping zone.
The shipping rule has options for each category in the system. Each shipping category can be set to:
- Allow. Products of this shipping category can be allowed for this shipping method.
- Disallow. If products of this shipping category are found in the cart the rule will not match the cart.
- Require. Products of this shipping category must exist in the cart for this rule to match.
In addition to the shipping zone and shipping category matching, various order information can be used to determine a match of the rule, such as order cost, order item quantity, and total order weight.
Shipping Rule Conditions
This condition is met if the order’s shipping address falls within this zone.
Minimum Order Quantity
This condition is met if the order has at least a certain number of items.
Maximum Order Quantity
This condition is met if the order quantity does not exceed a certain number of items.
Minimum Order Total Price
This condition is met if the total order price is at least a certain amount.
Maximum Order Total Price
This condition is met if the total order price is no more than a certain amount.
Minimum Order Total Weight
This condition is met if the total order weight is at least a certain amount.
Maximum Order Total Weight
This condition is met if the total order weight is no more than a certain amount.
For each shipping categories, this rule can allow, disallow, or require certain products to match this rule.
Shipping Rule Costs
Set a base shipping rate for the order as a whole. This is a shipping cost added to the order as a whole and not to a single line item.
The minimum the person should spend on shipping.
Maximum Base Rate
The maximum the person should spend on shipping after adding up the base rate plus all item level rates.
Item level rates:
Default Per Item Rate
Set a per order item shipping rate.
Default Item Weight Rate
Cost per whole unit of the store’s dimension units. For example, if you set your dimension unit option to Kilos, and your product weight was 1.4Kg, and you enter 1 as the item weight rate, then the price will be $1.4
Default Percentage Item Price Rate
The amount based on a percentage of items cost.
In addition to the default item level rates, you can override the default values with shipping category specific per item, weight, and percentage rates.
If a customer changes their shipping address during checkout, a previously selected shipping method may no longer match and will be immediately removed as the shipping method set on the cart.
