Description

The Product Add-ons addon extends WooCommerce’s product setup with customizable extra fields on the details page, letting the customer choose options like engraving, gift wrapping, file upload, or additional colors before adding to the cart. Each option can add a fixed or percentage value to the final price, automatically adjusting the total at checkout and keeping the information visible on the order and the invoice.

Key Features

  • Custom fields on the product
    Adds text boxes, checkboxes, radio buttons, selects, and upload areas to each item’s page.
  • Variable charge per option
    Assigns a fixed or percentage surcharge to each choice, recalculating the price in real time.
  • Global or per-product application
    Allows creating option groups reusable across multiple products or exclusive to one SKU.
  • Required and conditional fields
    Marks options as required and sets minimum and maximum selection limits per group.
  • Logged on the order and in the email
    Saves the choices in the customer’s history, in the admin panel, and in automatic notifications.

Benefits of Product Add-ons

  • Higher average order value
    Sells services and customizations as paid add-ons without creating duplicate variations.
  • Leaner catalog
    Avoids duplicating products for every possible combination, reducing setup work.
  • Custom orders without friction
    Captures customer instructions and preferences right at the moment of purchase.
  • Clearer operations
    Delivers the internal team every customization detail alongside the approved order.

Who Is It For?

  • WooCommerce store owners who sell customizable products, such as printed t-shirts, engraved jewelry, or print-on-demand items.
  • Service businesses that charge for optional add-ons, such as installation, premium packaging, or shipping insurance.
  • Operations with a large catalog that need to avoid multiplying variations for every customization combination.

Product Add-ons positions itself as a customization layer over the WooCommerce engine, eliminating the need for theme or template customizations to offer paid choices on every product. Pricing, requirement, and display rules are centralized in the panel, giving the store owner direct control over how each optional variation appears to the buyer and impacts the final order value.
