Stock WooCommerce has no product options

Stores often sell products with add-ons: engraving, gift wrapping, an extra service. Without option fields the customer cannot provide that information, and the store cannot charge for it.

  • No fields for extra product options
  • No way to charge for an add-on
  • Manually arranging add-ons by contacting the customer
  • No lightweight path to options without a heavy admin surface

Add-Ons adds priced product options

  • Option fields: text with character limits, checkbox and select list
  • Each option can be paid or free
  • The price adjusts automatically to the chosen options
  • Customer choices visible in the cart and the order

What you get in the free version

Field types

Text fields, checkboxes and select lists, defined per product in the Add-Ons tab.

Text limits

Text fields can have minimum and maximum character lengths, with a live counter and server-side validation.

Each option can have an extra price or be free, added to the product price.

Field validation

Required fields are checked before adding to cart, with a clear message for the customer.

What PRO adds, and why it matters

Conditional logic

Show or hide product options depending on the customer's earlier choices in the product data panel.

Front-end hiding

Inactive options are hidden on the product page and their inputs disabled.

Server-side validation

Required fields on inactive conditional options are skipped when adding to cart.

File uploads

A file field with size limits, allowed extensions, cart validation and order item metadata.

Quantity-based options

A separate add-on quantity multiplies the selected option price, with min/max limits and cart/order metadata.

Swatches

Colour or label swatches instead of a plain select list.

Per-option inventory

Stock limits for individual add-ons, with sold-out hiding and order-complete deduction.

Per-character text pricing

Charge text personalisation by typed character, with optional space exclusion.
