Drawer or embedded
Show the offer as a pop-out drawer with a static or fixed trigger, or as an inline section right on the product page. Same selection and cart flow either way.
Build-a-box for Shopify
Let shoppers build their own box, right from your product page.
BigBox adds a customizable bundle drawer or inline offer to your product pages. Customers pick what goes in, unlock tiered rewards, and check out with real cart lines. No separate bundle products to maintain.
Adds a theme app block - no manual theme-code edits.

From product page to packed box in five steps.
BigBox is organized around Bundles, Analytics, and Settings. Here's the path from a fresh install to a live offer.
01
Create a bundle
Name your offer and set it live or keep it as a draft. BigBox blocks conflicting active bundles on overlapping product pages, so two offers never compete for the same page.
Bundles 02
Choose where it appears
Pick the exact product pages the offer can show on. The drawer only renders when the page has an eligible bundle for that product, customer, market, and schedule.
Active products 03
Pick what goes in the box
Fill the box from selected products or whole collections, with optional variant restrictions. Set the minimum and maximum number of products a shopper can add.
Contents 04
Set the rewards
Add up to five quantity-based tiers - percentage off, a fixed amount off, or free shipping. Discounts apply through Shopify Functions when the cart qualifies.
Rewards 05
Add the block, then watch it sell
Drop the BigBox app block onto your product template in the theme editor - no theme code. Then track views, opens, cart additions, and paid orders as they come in.
Theme editorEverything a build-a-box offer needs - and nothing it doesn't.
Products or collections
Build the box from hand-picked products or entire collections. Restrict variants, hide out-of-stock items, and set the minimum and maximum box size.
Tiered rewards
Reward bigger boxes with percentage or fixed product discounts and free shipping - applied automatically at checkout through Shopify Functions.
Real cart lines
Selected items are added as real Shopify cart lines with BigBox attribution properties - not a separate bundle product you have to keep in sync.
Yours to style
Customize drawer colors, button radius, type sizes, copy, card labels, and progress messages so the box looks like it was always part of your store.
Discount guardrails
Every offer is tagged BigBox. The editor checks the connected discount's health and shows a one-click repair if it goes missing, expires, or drifts.
Two ways to put the box in front of shoppers.
Both modes share the same product selection, tier progress, and cart flow. Choose per product template in the theme editor.
A pop-out box builder
A trigger button opens a focus-managed drawer over the page - overlay, close controls, a live progress region, and a sticky checkout footer. After adding, send shoppers to the cart or straight to checkout.

- Width
- Full-width or fit-content

- Cart or checkout
An inline offer block
Render the builder as a section right on the product page - the same tiers, search, and cart flow, laid out as a grid or slider. It's always visible, so there's no click before shoppers start filling up.

Straight answers before you install.
Do I need to edit my theme code?
No manual theme-code edits. You add the BigBox app block to your product template from the Shopify theme editor, and the app home page deep-links you straight to it.
How do the discounts actually apply?
Through Shopify automatic app discounts and Shopify Functions, using Shopify-resolved product, variant, customer, and market context. The discount applies at checkout whenever the cart qualifies.
Are bundle items real cart lines?
Yes. Selected items are added as real Shopify cart lines with BigBox attribution properties - there's no separate bundle product to create or keep in inventory sync.
How is order revenue attributed to a bundle?
Paid-order analytics are recomputed from Shopify orders after order webhooks, for orders that retain BigBox line item properties. It reflects paid outcomes rather than live, real-time numbers.
Can two offers collide on the same product?
No. BigBox blocks conflicting active bundles on overlapping active products when their eligibility scopes overlap, so one product page never serves two competing offers.
What happens if a connected discount breaks?
The bundle editor checks whether the connected Shopify discount exists and is active. If it's missing, expired, or invalid, you get a one-click repair, and discount webhooks attempt recovery automatically.

Add BigBox, drop in the app block, and let shoppers assemble their own box - rewards and analytics included.
