Add-ons let customers upgrade what they are already buying, while they personalize it. The extra shows up in the price as they choose it, and travels into Shopify checkout on the same order.

What an add-on actually is
A question you attach to a product, with answers the customer picks from. Gift wrapping. A wooden frame instead of a paper print. Engraving on the back. Each answer can carry its own price, so a small frame adds less than a large one, and you can put a sale price next to it when you want to run an offer on the upgrade rather than the product.
- Price the add-on as a flat amount or a percentage
- Each choice carries its own price difference
- Choices can have a sale price of their own
It looks like part of the product, not a form
How a choice is presented changes how often it gets picked, so the presentation is yours to set. Colours belong on swatches. Frames deserve photographs. A yes-or-no upgrade is a toggle, not a dropdown with two entries. Pick per add-on: dropdown, radio, swatch, checkbox, toggle, button group, carousel or tile card.
- Eight ways to present a choice
- Choices can show a photo or a colour swatch
- Set the option you want selected by default
Options that only appear when they matter
Irrelevant options are the fastest way to lose someone halfway through. So an add-on can stay hidden until the customer's earlier answers make it worth asking. Show engraving only on the metal version. Offer the gift box only when they picked a gift message. Conditions combine with and and or, and nest deeply enough that even an awkward catalogue fits.

What happens at checkout
The surcharge follows the customer into Shopify without you keeping a second product in your catalogue. What that looks like depends on your Shopify plan, and it is worth knowing which one you get. On Shopify Plus the line is rewritten to the adjusted price, so the customer sees one line at one price. On every other plan the line becomes an indivisible bundle: the product and its surcharge, together, unable to be split apart in the cart. Composerie reads your plan and picks the right one for you.
- One adjusted line on Shopify Plus
- An indivisible product-plus-surcharge bundle on other plans
- Chosen from your plan, not configured by hand
The printer gets a product, not a surcharge
A surcharge is money, not something to manufacture, and a fulfilment workflow that cannot tell the two apart will try to print your gift wrapping fee. Composerie marks the surcharge so it is kept out of what goes to a provider. And where your printer has an option of its own, a paper stock or a frame finish, an add-on can be mapped onto it, so the customer's choice arrives as the provider's own value rather than as a note somebody has to read.
- Surcharge lines are marked and kept out of provider fulfilment

Questions, answered
Do I need a second Shopify product for the surcharge?
No, and that is the point. The surcharge rides along with the personalized line instead of living in your catalogue as a product customers could find and buy on its own.
How does the extra charge show up in the cart?
That depends on your Shopify plan. On Plus the line is rewritten to the adjusted price, so the customer sees a single line. On other plans the product and its surcharge become one indivisible bundle that cannot be split in the cart. Composerie reads your plan and applies the right behaviour rather than asking you to choose.
Can an add-on cost a percentage instead of a fixed amount?
Yes. Price it as a flat amount or as a percentage, whichever fits. A percentage suits upgrades that scale with the product, like a premium material on a range of sizes; a flat amount suits things like gift wrapping that cost the same whatever they are wrapped around.
Can I hide an add-on until it is relevant?
Yes. An add-on can depend on what the customer already chose, with conditions that combine using and and or and nest up to eight levels. Engraving appears once they pick the metal version; the gift box appears once they ask for a gift message.
Will my print provider try to produce the surcharge?
It should not. Surcharge lines are marked as such and kept out of what goes to a provider, because a gift wrapping fee is money rather than something to manufacture. Where your provider has its own option, like a paper stock, an add-on can be mapped onto it so the choice arrives as the provider's own value.
