Show the box inline or in a slide-in drawer, then set colors, corners, type sizes, and every line of copy. Fonts come from your theme, and the admin previews each change live.
Every box is one set of rules, edited in one place inside your Shopify admin.
Hand-pick products and the variants they come in, or pull in entire collections. Sold-out items can hide themselves.
Set a minimum and a maximum. Shoppers see the empty slots they still need to fill.
Everyone, chosen customers, customers whose tags match any or all of a list, or specific markets.
Start and end dates in your store's time zone, for launches and holiday drops.
Point a block at the box's handle, or attach parent products so the block on their product pages finds the box by itself.
Choose which of your other discounts can combine with box rewards.
The editor sums up every rule as you go, previews the box in your storefront's styling, and duplicates it when the next drop comes around.
No hidden bundle product and no discount codes. Every pick is a real cart line, rewards run on Shopify Functions, and each paid order traces back to its box.

PaidRecomputed from the paid Shopify order.
The editor flags a missing or inactive discount and recreates it in one click. Discount webhooks try to recover it automatically.
Two active boxes can't claim the same product for the same shoppers. BigBox blocks it before it goes live.
It is an app block you place in the theme editor, so your theme files stay untouched.
Real cart lines mean stock counts, fulfillment, and 3PL flows see exactly what sold.
Box data is served from an edge cache, while schedule, market, and customer checks stay live.
Keyboard support, focus handling in the drawer, screen reader announcements, and reduced motion respected.
Follow every box from view to purchase. Sales are recomputed from paid Shopify orders, so the numbers reflect money that actually came in.

Everything else is in the help center, and thetutorial walks through a full setup.
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.
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.
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.
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.
A tier's reward can be a free gift: one product you pick. When a shopper reaches the tier, the gift is added to their cart automatically and discounted to free at checkout through Shopify Functions. If the gift has several variants, the shopper chooses one before adding the box, and gift items never count toward tier progress.
No. BigBox blocks conflicting active bundles on overlapping active products when their eligibility scopes overlap, so one product page never serves two competing offers.
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.
