About the App

Add-On Picker turns every product page into a chance to sell more. Choose the products that go well with an item, such as a case for a controller or a cable for a charger, and shoppers see them as a short checklist right above the quantity box. They tick what they want, choose a size or colour where needed, and one click on Add to Cart puts everything in the cart.

Add-ons are real products, not options. Each one goes into the cart as its own line item with its own price and stock, so your inventory, reports and fulfilment stay accurate.

WHY MERCHANTS USE IT

  • Help raise average order value with relevant extras at the moment of purchase

  • Offer the same accessory on as many products as you like

  • Keep stock and order data clean, because every add-on is a separate cart item

  • No theme code to edit: the app installs its storefront script for you and removes it when you uninstall

WHAT SHOPPERS SEE

  • A clear checklist with image, name and price, right where they choose the quantity

  • Add-ons with variants show size or colour pickers once ticked, and the price, image and stock update as they choose

  • Sold-out add-ons and sold-out variants are clearly marked and can't be added

  • If a required option is missing, a short message explains what to choose, and nothing is added until the choice is complete

WHAT YOUR TEAM GETS

  • Up to 20 add-ons per product, picked from your catalog by name or SKU, in the order you set

  • A product list you can sort by name or newest first, and filter by add-ons set or not, stock status and storefront visibility, including hidden products

  • Stock status and add-on count for every product at a glance

  • The add-on editor in the Apps menu, and from the ⋯ menu on any product in Products › View

  • Changes show on your storefront within about 10 seconds

  • Settings to turn the list on or off, change its heading and, if your theme needs it, choose where it appears

  • A built-in setup check that confirms permissions, the storefront script and the product menu entry are in place

GOOD TO KNOW

  • Works with Stencil themes on your default storefront

  • Each ticked add-on is added with a quantity of 1

  • Products with required text, file upload or checkbox fields aren't offered as add-ons

To get started, install the app, open a product, choose its add-ons and save. They appear on the product page within seconds.

App Features

Cross-sell add-ons above Add to Cart

Show related products as a checklist right above the quantity box, with image, name and price. Shoppers tick what they want, and one click on Add to Cart adds everything.

Add-ons with variants and live stock

Add-ons with size or colour options show pickers once ticked, and the price, image and stock follow each choice. Sold-out add-ons and variants are clearly marked and can't be added. A missing option is flagged before anything goes into the cart.

Separate cart lines, accurate inventory

Each add-on goes into the cart as its own line item with its own price and stock, not as an option on the main product. Your inventory, reports and fulfilment stay accurate.

Fast setup from your product list

Pick up to 20 add-ons per product by name or SKU, set their order, and reuse the same add-on on any number of products. Sort by newest, filter by add-ons, stock status and visibility, and open the editor from the ⋯ menu in Products › View.

No theme code to edit

The app installs its storefront script for you, places the list above the quantity box automatically, and removes it when you uninstall. Change the heading or placement in Settings. Saved add-on changes show on your storefront within about 10 seconds.

Case Studies

Panda Wagon: Hatsune Miku extras, added in one click

Panda Wagon, a BigCommerce store selling licensed collaboration gaming and music gear, wanted to offer matching extras on its product pages, but the built-in pick lists allowed only one extra per list, could not include products with sizes or editions, and added each extra as an option on the main product instead of its own item. With Add-On Picker, the team added a headset and a messenger bag from the same Hatsune Miku series to the cubyfun Pocket Music Keyboard Gift Box page in a few minutes, without theme changes. Shoppers now tick the extras right above the quantity box, and one click adds the keyboard and each extra to the cart as separate lines with their own price and stock, so orders are easy to pack and sold-out extras can't be ordered.
