Add-ons

With add-ons you can offer optional extras for your products that customers can add via a checkbox on the product page — for example a greeting card enclosed with the parcel, or gift wrapping. Add-ons can be free or paid.

Add-ons are created once centrally and then enabled per product. So you set up “Greeting card” a single time and activate it for as many products as you like.


  1. You create an add-on in the central add-on pool (name, price, options).
  2. In the product editor you tick which add-ons should be available for that product.
  3. On the product detail page the customer sees the enabled add-ons and selects them via checkbox.
  4. The chosen add-ons appear in the cart, in the order, the confirmation email, and on the invoice & delivery note.

  1. Open the admin area
  2. Go to Shop > Add-ons
  3. The list of all created add-ons is displayed

  1. Tap the plus icon (+) in the top right
  2. Enter the name (e.g. “Greeting card”) — can be maintained in multiple languages
  3. Decide whether the add-on is paid (see below)
  4. Decide whether the customer may choose the quantity
  5. Optional: add an info text for the customer
  6. Tap Save

FieldDescription
NameThe label of the add-on shown to the customer. Multilingual.
PaidToggle. Off = the add-on is free. On = a price field appears for the surcharge.
PriceSurcharge per item (only visible when “Paid” is on).
Quantity selectableToggle. Off = simple checkbox (exactly 1×). On = the customer can choose a quantity (e.g. 3 greeting cards).
Info textOptional note. When set, an info icon appears next to the add-on for the customer.

Leave the Paid toggle off. The add-on is shown to the customer as “Free” and does not change the order total. Ideal for a card that you already keep in stock and simply enclose.


If you provide an info text, a small info icon appears next to the add-on on the product page. When the customer taps it, a sheet opens with your note — perfect for explaining exactly what the add-on includes.

  1. Open the add-on for editing
  2. Enter your note in the Info text field (multilingual)
  3. Save

  1. Open the product editor (Shop > Products > tap a product)
  2. Scroll to the Add-ons section
  3. Enable the add-ons that should be available for this product
  4. Save

On the product detail page, the enabled add-ons appear below the product options, right above the “Add to cart” button:

  • Without quantity selection: a checkbox per add-on, with name and price (or “Free”) next to it.
  • With quantity selection: a quantity stepper (− / +) instead of the checkbox.
  • With info text: an info icon that opens a note sheet.

The chosen add-ons and their surcharge then appear in the cart, in the order, the confirmation email to the business, and on the invoice and delivery note.


  1. Open Shop > Add-ons
  2. Tap Edit or Delete on the desired add-on
  3. Confirm the safety prompt when deleting

How does an add-on differ from a product variant?

Section titled “How does an add-on differ from a product variant?”

A variant is a version of the same product (e.g. size or colour) — the customer picks exactly one. An add-on is an optional extra added on top of the product — the customer can select or deselect it, independent of the variants.

Can an add-on be free for one product and paid for another?

Section titled “Can an add-on be free for one product and paid for another?”

No. The price of an add-on is set centrally in the pool and applies everywhere. If you need different prices, create two separate add-ons.

Does an add-on count against the product’s stock?

Section titled “Does an add-on count against the product’s stock?”

No. Add-ons have no stock of their own and do not affect product stock.
