# What it is The Bundle Builder lets a shopper pick several products, combine them into one bundle at a deal price, and add the whole thing to cart in a single step. It's the build-a-box format leading CPG and supplement brands run — "build your own kit," "mix and match and save." It's included in every Boost plan, no extra app to install. And you don't get just one — you can run up to **three separate bundle builders**, each with its own box sizes, its own product selection, and its own link, so you can point different builders at different audiences.
# The problem it solves Build-a-box is the format CPG customers want — but the usual way to offer it works against you: * **It's a separate app, bolted onto your store.** Adding a build-a-box means installing a dedicated bundle app — another install, another bill, another widget that loads slow and clashes with your branding. * **The experience is clunky, and worst on mobile.** Most bundle tools cram size, every product, and the deal onto one cluttered page. On a phone it's overwhelming, and shoppers give up before they finish — a builder customers abandon makes you nothing. * **One builder can't serve every channel.** Your main site, your email list, and your ad traffic each want a different offer — but a single bolted-on builder forces one configuration for all of them. Boost fixes the part that matters: build-a-box that's included, built-in, and good — three of them, each tuned to a different audience.
# How it works Boost gives your shopper a clean, focused bundling flow, and gives you up to three builders to deploy however you sell. **1. Pick the products.** The shopper chooses the items they want in their bundle from the selection you set, on a fast, brand-matched screen that's easy to tap through on mobile. **2. The deal builds as they go.** A "buy more, save more" discount grows as they add items, so shoppers are nudged toward a fuller bundle — the bigger box becomes the obvious choice. **3. Check out as one order.** The finished bundle adds to cart as a single order, with every product as a real line item, so your fulfillment and 3PL see exactly what's inside. You configure each of your three builders in a setup wizard — separate box sizes, products, and discount for each — and give each its own link to drop on your site, in an email, or behind an ad. No code, with a live preview before you go live.
# What you get * **A bigger average order.** A built bundle is a multi-product order, and the "buy more, save more" deal pushes it bigger — more revenue from the same traffic. * **Three builders, three channels.** Run one on your main site, one for email, one for ad traffic — each with its own products, sizes, and offer, so every audience gets the right bundle. * **An experience shoppers finish.** A focused, mobile-first flow means more completed bundles than a clunky bolt-on builder — especially where most of your customers shop. * **Included, not another app.** It's part of Boost, not a separate bundle app to install and pay for — one platform, one bill, native to your store.
# Works with your stack * **Is this an add-on?** No — the Bundle Builder is included in every Boost plan. It's part of the Boost foundation, not a separate app or an extra bill. * **Do I really get three builders?** Yes. You can run three distinct bundle builders at once, each with its own box sizes, product selection, and link — built to target different audiences and channels. * **Will it mess up fulfillment?** No. Every product in a bundle adds as a real line item, so your 3PL, inventory, and reporting see the true contents of every order. * **Where does it run?** Natively in the Boost storefront your shoppers already use — your branding, your products, no separate widget fighting your theme.
