Custom option fields for your products, with price add-ons
Smart Product Options – Custom Product Fields for WooCommerce
Add a text field for engraving, a dropdown to pick a variant, a checkbox for an extra service — each with its own price add-on — right above the “Add to Cart” button. The price updates live, and every selection is carried through to the order confirmation email.
What’s included for free
One global option group, applied to all products or a chosen list — enough to start selling with custom option fields the same day.
5 Field Types
Text, text area, checkbox, radio buttons, and dropdown — each with a flat price add-on on the field or per choice.
Live Price Updates
Customers see the price add-on update as they fill in the fields, before they even add the product to their cart.
Cart to Order
Selections and price add-ons carry automatically through the cart, checkout, order confirmation email, and the admin order screen.
What you get with PRO
When one option group isn’t enough — unlimited option groups, advanced field types, and smarter pricing.
Unlimited Option Groups
Build as many field groups as you need and assign each one to products, categories, tags, or even a specific variation.
More Field Types
Image swatches, color swatches, file uploads, date/time pickers, a range slider, and quantity-tiered pricing.
Percentage Pricing & Limits
Price add-ons as a percentage of the product price (not just a flat amount), plus text length and value range limits.
Conditional Logic
Show a field only when a customer picks a specific value in another field — e.g. “Engraving Text” only appears if “Add Engraving” is checked.
