POS limitations

The option types and add-on mode that do not work in Shopify POS, and what to use instead.

Read this before you build anything for POS. None of these limitations produces an error message. An option is missing, or an add-on is not charged.

The three limitations

Not supported in POS	Use instead
Dimension	Number fields, one per measurement
Product links	Nothing needed — staff can find the other product in POS directly
The Fixed amount add-on mode	Existing product or New product

The app warns you about the two option types when you add them. Each one displays a notice saying it is not supported on the POS channel.

Fixed amount is the one to check

Staff notice a missing field, so the two option types are visible problems. Fixed amount is not. The option appears, the customer selects it, the sale completes, and the charge is not applied.

If an option set is published to Point of Sale, check every add-on it contains. Any value using Fixed amount is not charged at the counter.

Both product-backed modes work in POS. To switch, open the value's Price field and change the tab.

Auditing an option set for POS

1

List the option sets published to POS

On the Option Sets list, check the sales channels shown on each row.

2

Open each one and check every priced option

For input types, check the Price field under Add-on Settings. For selection types, check the Price column for each value.

3

Change any Fixed amount value to a product-backed mode

New product is the simplest replacement. It charges the same price and works in POS.

4

Remove or replace Dimension and Product links options

Alternatively, move them into an option set published to Online Store only.

5

Test a real sale in POS

Add the product, complete the options, and check the total before finishing the sale.

Other differences from the storefront

Behavior	In POS
Country rules	Not a meaningful filter — an in-person sale has no browsing country
Customer rules	Depend on a customer being attached to the sale
Widget placement, colors, typography	Not applicable. POS renders its own interface
Match theme style	Not applicable
Quickview and other page settings	Storefront only
The Personalizer	Built for a product page with a photograph. Treat it as a storefront feature and test carefully before relying on it at the counter
Personalizing an add-on line	Not possible. Add-on lines belong to the item they were added for

Recommended setup

If your online form is long or uses unsupported types, create two option sets:

Option set	Sales channel	Contents
Your full form	Online Store only	Everything, including Dimension and Product links if you need them
A counter form	Point of Sale only	Only what staff need while a customer waits, with product-backed add-ons throughout

Both target the same products. Because each is published to one channel only, they do not overlap.
