Upsell your product design with Addon Charge (additional charge)

What is Addon Charge

Addon Charge is an element in the personalization form that can help you offer some addon features to your customers to increase order value.
When customers select an option in Addon Charge, it'll add an extra fee to the line item price.

Charge method

Addon Charge supports two charge methods:

Add a separate addon item to the cart (default): each option is linked to a Shopify variant. The main product and addon appear as separate items in the cart and checkout. Existing Campaigns keep this behavior.
Adjust the item price directly: each option has a Price, set separately for each store. The charge increases the main item's price without adding a separate addon item. No addon product is needed for this method.

Adjust the item price directly is available for Shopify stores using Artwork 2.0. It requires Teeinblue's cart transform to be active on the store. If the charge appears on the product page but is missing from the cart or checkout, contact contact@teeinblue.com.

For example, a $30 shirt with a $5 “Size XXL” option appears as one $35 item in the cart and checkout.

Set up direct price adjustments

In Teeinblue Portal > Artworks > open an Artwork > edit the Addon charge Layer > Personalization Settings > Create a new option > Charge method, select Adjust the item price directly.

In Teeinblue Portal > Artworks > open the Artwork > edit the Addon charge Layer > Personalization Settings > Option values, click Add next to an option's Price (or Edit for an existing price).

In the Price popup, click Add next to the target store and enter the extra amount in that store's currency. Click Close. Repeat for other options or stores, then click Save & Close in the Artwork editor.

Notes for direct price adjustments

With multiple selections (checkboxes), the charge is the total price of the selected options. It also adds to Charge by character count on the same product.
An option is free if its price is blank, zero or negative, or if no price is set for the current store.
When option prices are displayed, the option label includes the extra amount, such as +$5.
For an Addon Charge Global Option, the Global Option determines the charge method. The same Global Option reused across Layers or Artworks is charged only once.
Switching charge methods preserves attached variant settings for when you switch back.

Zero-price variants: direct price adjustments do not apply when the main product variant costs $0. The option can still display +$5, but the item remains $0 in the cart and checkout. Charges on other items are unaffected.

How to add a separate addon item

The steps below use Add a separate addon item to the cart. Shopify product and variant requirements in this section apply to that method.

Note**: All addon items, whether created in Teeinblue or not, are treated the same as Teeinblue items. Therefore, the Addon Charge product will be included in the transaction fee**.

1. Create a Shopify product

We need a Shopify product to add it to cart for extra charges.

This product will be visible to your customers when they add the main Teeinblue product to cart.

Go to your Shopify admin > Products > Create a new product.

In the variants list, create the variants representing the additional charges you offers. For example: variant "1 name" - $5, variant "2 names" - $10, variant "3 names" - $15...

Remember to set Inventory or untick the "Track inventory" for unlimited stocks for these variants.

2. Add option in Artwork

Go to Artwork editor, click on "+ Layer" button > Addon Charge

It'll create a new layer with no image (same as "Additional option"), only show up in the personalization form.

Edit that "Addon charge" layer.

Set an "Option title" and the extra charges in "Option values"

Click on "Attach charge" button to connect each option with a Shopify variant. Then when customers select an option, it'll add to cart the attached variant for extra charge.

Select the product you created in step 1 and select the correct variant to charge for this option.

Then click "Attach" to link the variant to this option.

If you have multiple stores, you can attach a product to each store.

Do the same for other options in the Addon charge.

Currency might display incorrect in portal, but should be correct on storefront.

(optional) Set condition to only display some layers if the "Addon charge" matches the correct option.

For example: the 3rd name only appears when "Addon charge" = "+1 name"

Then when customers choose an "Addon charge" option and add to cart the main product, the attached "Extra charge" variant will be added along.

3. Other settings

You can turn off the price attached to each option in Store settings > Product page settings > Addon Charges

Some best practices

Using Addon charge, you can upsell with:

Change designs: change clipart, change text color, upload photo...

Add more designs: more names, more people, upload more photos...

Offer additional services: gift wrapping, shipping insurance...

Offer additional products: buy a stand, a case, a frame...

Attach the Addon Charge Product to Artwork Template

Open the Edit Template panel, then continue to click on the toggle for Extra charge for this template

Make sure to select the correct variant you created in Shopify earlier and apply it to your template.

Repeat this process for any other templates you have.

Once all is good, be sure to double-check it and launch it to your Store!

Notes:

If your Addon Charge product is a physical product, and you want to track its inventory, please make sure the variant has to be available for the Customers to make purchase

Or, you can un-check the Track quantity checkbox so the Customers can always purchase it

In order for the Addon Charge Product to work, it has to be active on your Sale Channel.

You can hide your Addon Charge Product from search, or showing up on your Storefront via by going into your Shopify Admin > Products > Status > select Unlisted

This new feature from Shopify hides products from store search and collections, all sales channels, internet searches and Shopify Catalog—while still allowing access via a direct URL. It’s ideal for private sales, warranties, add-ons, or “free gift with purchase” items you don’t want discovered or used outside of their intended purpose.
