# What makes WC Kalkulator unique ?

When designing the functionality of the plugin, we wanted to obtain software that would be easy to use and highly configurable and suitable for any type of store.

The plugin allows full freedom to define fields and formulas for calculating the price. Some of fields are not used in formulas, but you can use it to get informations from Customer (for example: text, date, date range, color, dropdown, etc.)

# Definitions

  • Field - is used to get user's input on the woocommerce product page. Custom Field can be used to calculate the price (is used in formula)

  • Fieldset - store manager can create the fieldset (set of custom product fields) which consists of different Fields. Fieldset must have at least one Field and the expression (formula) to calculate the product price

  • Expression/Formula - mathematical and/or logical expression using to calculate the woocommerce custom price. The expression can be single-line (one-line) or conditional. Expression is protected and calculated only server-side.

  • Validation - each Field has specific requirements to be met. Incorrect values make it impossible to calculate the woocommerce custom price and add the product to the cart.
