Use case
Consider a store that offers additional paid options such as gift wrapping or priority processing using pricing fields. When a customer selects one of these options during checkout, the extra cost is added to the order total.
By enabling this feature and selecting the relevant pricing field, the chosen option along with its additional price will also be displayed in the generated invoice and packing slip. This provides complete transparency for both the store owner and the customer, ensuring all charges are clearly documented.
