Where you can set add-ons

Option level or option value level. Where the Price field is on each option type, and what to do when a type cannot carry a price.

The location of the price field depends on the option type. Check the tables below before you look for a field that may not exist on that type.

Two levels

Level	Where the field is	Because
Option level	Basic, under Add-on Settings, labeled Price	The option has one answer, so one price
Option value level	The Price column in the option values table	Different choices usually cost different amounts

The price field sits on the option for input types, and on each value for selection types.

Input types take one price; selection types take a price per choice.

By option type

Option level

These five option types have a single Price field for the whole option:

Type	Typical use
Text	An engraving fee, flat or per character
Textarea	A message printing fee
Number	A per-unit charge driven by the number entered
Switch	One paid extra, on or off
Color picker	A custom-color surcharge

Option value level

These nine option types take a price for each value, set in the values table:

Type	Typical use
Select, Dropdown	Tiers or grades at different prices
Color dropdown, Image dropdown	Premium colors or designs
Radio button	Service tiers
Checkbox	A menu of extras, each priced
Button	Sizes or pack sizes at different prices
Color swatch, Image swatch	Standard colors free, premium ones charged

Values with no price are free. You can mix free and paid values in the same option, for example three free colors and two paid ones.

Each value can also use a different pricing mode. One value can link to an existing product, another can generate a product, and a third can use a plain price. The mode is set for each value, not for the option.

Its own arrangement

Type	How pricing works
Dimension	An Add-on price field plus a Formula, so the price is calculated from the measurements. See Dimension add-on formula.

Cannot carry a price

Type	Why
Phone, Email	Contact details, not paid choices
Hidden field	The customer makes no choice
Date and time picker	A date is not a stocked item
File upload	An upload is not a purchase
Range slider	Use Number if the value should drive a charge
Font picker	A presentation choice
Product links	It navigates away rather than adding anything
All nine static types	They collect nothing

Charging for an option that cannot be priced

Some option types cannot carry a price, such as a date picker used for an express delivery fee, or a file upload with a setup fee. Use the following method:

1

Add a Switch or Checkbox next to it

Apply the price to this option. Use a Switch for a single charge, or a Checkbox for several.

2

Word it as the thing being paid for

For example, Express production (+$10.00) or Artwork setup fee. The label should make clear what the charge covers.

3

Reveal the unpriced option conditionally

Place the priced Switch above the unpriced option, then use conditional logic to display the date picker or upload field when the switch is on.

4

Or the other way round

You can also reverse this. For example, display a "rush order" switch only after the customer selects a date within the next three days.

Worked examples

A file upload with a setup fee

Option	Type	Price
Artwork setup	Switch	$15.00, One time charge
Your artwork	File upload	None. Shown when the switch is on

Colors, mostly free

An Image swatch with eight values. Five are free, and three use New product so each premium finish has its own inventory.

Engraving priced by length

A Text option with Price $0.50 and Add-on quantity set to Per character. Set a Max character value to limit the total charge.

Notes

• The Add-on quantity dropdown that controls how a charge scales is always set at option level, even when the prices are set on the values. It applies to every value in that option.

• Mixed quantity is the exception. It gives each value its own quantity field, and is available on multi-select options only. See Advanced add-on modes.

• When a value is linked to a product, a Product column is added to the values table, with a link that opens the product in Shopify admin.
