Product options and price calculations

Learn how to add options such as size or color to a WEMASY webshop product, give each choice a price, and calculate prices from customer input.

Product options let customers choose or enter something before they add a product to the cart, such as a size, a color, a text to engrave, or a number of square meters. Each option can change the price.

Where to find it

Open Webshop, click Products, edit a product, and open the Options tab.

Option types

  • Text: a short text field, for example a name to print.
  • Textarea: a longer text.
  • Number: a number with a price, for example a quantity of meters.
  • Checkbox: an extra the customer ticks, with a price.
  • Select: a list of choices, each with its own price.
  • Calculation: a price calculated from other options.

Add a choice list such as size

  1. Open the Options tab.
  2. Click Add option.
  3. Choose Select.
  4. Enter the Title, for example Size.
  5. Tick Required if the customer must choose.
  6. Click Add option item for each choice.
  7. Enter a price for a choice that costs more.
  8. Choose Display: Dropdown or Buttons.
  9. Click Update.

Prices that depend on input

To multiply a price by what the customer enters, give the input field a Connection identification, a unique name. In a Checkbox or Calculation option, open Calculation options and click Add calculation rule. Use Multiply relation value or Add relation value, and enter the connection name in Value to use. Leave Value to use empty to use the current price.

Tick Show calculation to show the result to the customer. Tick Do not add price to total for an option that should not change the total.

Exclude the base price

Tick Exclude base price when the price comes only from the options. The product price is then not added to the options total.

Reuse options

Use Export and Import on the Options tab to copy a set of options from one product to another.

Tip: Use Buttons for short lists such as sizes, so customers see every choice at once. For more on products, see Adding products and Stock and inventory.

Frequently asked questions

Can each size have its own stock?

The Options tab sets choices and prices. Stock is tracked per product on the Basic tab.

Does Display change my prices?

No. Dropdown or Buttons only changes how the choices look. The order, prices, and default value stay the same.
