What Product Add-Ons does
Sell what the customer actually wants: an engraving, a gift box, a rush fee, a size, their logo. Product Add-Ons puts extra fields on the product page, charges for them, and carries the answers through the cart, the checkout, the order, the emails and the order editor.

Questions about Product Add-Ons
How is the price of an option charged?
Pick "Per product quantity" to multiply by the quantity, "Once per cart line" for a fixed amount however many are bought, or "% of the product price". Text fields can also charge per character, and number fields × the number entered.
Can a customer add a product with required add-ons from the shop grid?
No. The grid button becomes "Select options" and opens the product page. Products whose add-ons are all optional can still be added from grids, without add-ons.
Where do uploaded files go?
Into wp-content/uploads/pado/, renamed to a random name, so they cannot be guessed. Only the types you allow are accepted, and files are checked by content, not just by name. Staff see a link on the order; customers see the file name.
Do add-ons work with variable products?
Yes. The fields apply to every variation, and the live total uses the chosen variation's price.
How do I show a field only in some cases?
In the field's "Show only when" setting, pick another field in the same group and one of its options. Hidden fields are not required and are not charged.
What happens on uninstall?
Groups, per-product fields and uploads are kept unless "Delete all data" is ticked under Products > Add-Ons > Settings.
