6. Default calculators¶

Default calculators can be sufficient solution for many use cases.

6.1. Flat rate¶

The flat_rate calculator, charges concrete amount per shipment.

6.2. Per item rate¶

The per_item_rate calculator, charges concrete amount per shipment item.

6.3. Flexible rate¶

The flexible_rate calculator, charges one price for the first item, and another price for every other item.

6.4. Weight rate¶

The weight_rate calculator, charges one price for certain weight of shipment. So if the shipment weights 5 kg, and calculator is configured to charge $4 per kg, the final price is $20.

6.5. More calculators¶

Depending on community contributions and Sylius resources, more default calculators can be implemented, for example weight_range_rate.
