I’m looking for an app that allows a customer to add on another product within another’s product page and choose quantity. For example, I’m working on a store where where customers can easily select the number of curtain rod extensions they need based on the length of their window. There would be a single ‘Add to Cart’ button that automatically bundles the selected curtains and rods together, making it seamless for the customer to complete the purchase with just one click. Any apps that can achieve this?

It sounds like you’re looking for a way to create bundles of products with varying features.
Our app, StockHero Material Inventory, is designed to do just that!
-You can create bundles of products with adjustable quantities and features.
-The selected bundles can be added to the cart with a single click.
-Once a bundle is sold, inventory of the bundle’s components is properly tracked to prevent overselling or stock mismatches.

This doesn’t seem to quite help with what I need since the customer needs to be able to choose the quantity of each individual item in the bundle
Hi @52_Web
It sounds like you need a way to let customers easily add related products with a single click. I recommend Easify Product Options—it allows customers to select additional items like curtain rod extensions directly on the product page and choose the quantity. Everything gets bundled under one “Add to Cart” button, making the process seamless. It’s easy to set up and requires no coding.

- This is the app setting:
To allow your customers to choose the quantity for rod extensions, you just need to enable the *'*Allow Quantity Selector for option value’ in the Advanced Setting like this:
- This is the cart
I hope this answer helps solve the problem. If you have any further questions, please let me know or reach out to Easify anytime!

Hi @52_Web
What you’re describing is a setup where customers can pick an add-on (like curtain rod extensions) with a quantity selector, and then everything gets added to the cart with one click. Apps that handle bundles or product options can do this for one-time purchases.
For stores running subscriptions, Driftcharge also supports add-ons directly inside the subscription flow, so customers can choose the main product and any extras in one step. That way it works for both single purchases and recurring orders.

Hello @52_Web,
You can use Push Bundle- Build a Box app for your requirement.
Push Bundle lets you create bundles of multiple products and shows them on a single product page with every products and variants. This way customers can easily select the quantities of the products and variants and with just one click on the add to cart button all the selected products will be added to the cart.
If you want I can also share the demo product with you so that you can check it.
I’ve seen a few stores solve this with bundle or “build your own set” apps. Something like Easy Bundle Builder or Shopify’s own Bundles app can handle quantity selection for related items on one page. Just make sure the app updates inventory properly when the bundle sells, that’s the usual pain point.
