There are different options to manage pricing synchronization according to the fields sent:

Retail price: If this field is provided, it is automatically saved into PrestaShop without any other calculation.

Retail price with tax: When values are sent through this field, the process takes the current rule from PrestaShop, subtracts the tax when it exists, and keeps the result in the database as the retail price. If there is no rule added for calculating the price, the assigned value is the same as the retail price.

Tax rule: This field allows you to indicate the ID or full name of the rule established in PrestaShop for the tax to use. It can be used in two ways:

• Choose the id_tax_rules_group from PrestaShop. By default, if the plugin receives a numeric value, it searches the proper table. If it does not find it, the value assigned by default in the e-commerce is used. This is the best option for information integrity.
• Choose the tax percentage directly. To make the plugin work this way, add the suffix % in the Sales Layer export field, either manually or with a formula such as CONCAT({THIS}, "%"). This assignment is made with the first record that matches the indicated percentage.

wholesale_price: Wholesale price for PrestaShop. If the data does not exist, it is autocompleted with the retail price.

unit_price_ratio: The relationship between product unit and price.

unity: Text that shows the unit for the price in unit_price_ratio, for example Kg or Ud.

additional_shipping_cost: Added price for shipping.
