Biscuits Bundles

Biscuits Bundles is a build-a-box app built directly on the Shopify Bundles platform. That means your bundles are real Shopify bundle products with native inventory sync, no workarounds or middleware involved. The multi-step accordion builder gives your customers a guided "wizard" experience, walking them through required and optional steps to build their box.

Key features

• Multi-step bundle builder with collapsible accordion steps for a clean, guided UX

• Required and optional steps with single-select, multi-select (min/max), and quantity selectors with total limits

• Five pricing models: sum of products, fixed price, percentage off, amount off, and volume discount tiers

• Visual card editor with drag-and-drop ordering at both product and variant level

• Live inventory powered by Shopify's native bundle system, with sold-out display options and location-based availability

• Theme editor integration via app blocks (Online Store 2.0 required)

• Multi-language support with full translations

Pricing

Biscuits Bundles offers a free plan. Paid plans start at $5/month. Because it uses native Shopify Bundles under the hood, there are no extra charges for inventory sync or order processing.

Best for

Biscuits Bundles is ideal if you want your build-a-box to use Shopify's native bundle infrastructure for reliable inventory tracking and clean order data. It works especially well for food and gift merchants who need volume discount tiers and location-based stock. Keep in mind it requires an Online Store 2.0 theme, works on the Online Store channel only (no POS or Shop app), and is not compatible with subscriptions or draft orders. You can see live examples on the Biscuits Bundles demos page.

Boxi: Bundle Builder & BYOB

Boxi is a focused build-a-box app that earns praise for its simplicity and hands-on support. Boxi is a Shopify app that empowers businesses to create personalized product bundles, such as gift boxes or BYOB sets. It carries the Built for Shopify badge, confirming it meets Shopify's highest standards for performance and integration.

Key features

• A visual editor lets you configure styling, and you can create as many steps with as many products as you wish inside the builder.

• Custom field steps let customers personalize their boxes (for example, adding a gift message), purchase rules set minimum quantities per step, and flat or tiered discounts make offers appealing.

• The interface supports 15 languages for global accessibility.

• The builder can be used as a standalone page or embedded into your products and collections.

Pricing

Boxi offers four paid plans ranging from $21 to $185 per month, depending on your monthly sales and features. All plans come with a 14-day free trial, and there's a free option for development/partner stores.

Best for

Boxi is a strong choice for gift box and hamper stores that want a clean step-by-step builder without a steep learning curve. One merchant running a gifting business described it as "the only app that handled everything I needed: custom steps, beautiful UX, easy product organisation, and seamless integration." If you need subscriptions or 3PL SKU breakdowns, you will need to look elsewhere.

Easify Box Bundle Builder BYOB

Easify Box Bundle Builder stands out with a massive template library and custom field support that most bundle apps lack. Easify stands out with its massive template library (30+) and custom field support, including gift message fields and file uploads that most bundle apps lack. It also carries the Built for Shopify badge.

Key features

• With 30+ pre-built templates, a visual editor, and smart conditional logic, it handles everything from gift boxes to custom kits to subscription bundles.

• The app supports tiered discounts, volume pricing, custom fields (gift messages, date pickers, file uploads), and real-time analytics.

• Subscription box support lets your bundle products become recurring revenue.

• 24/7 live chat support and quick setup make it accessible for merchants of all experience levels.

Pricing

The free Start plan is genuinely useful, and the 14-day trials on paid plans let you test without risk. Paid plans scale based on monthly box revenue, making it budget-friendly for stores just starting out with bundles.

Best for

Easify is particularly strong for gift box stores, subscription boxes, and seasonal bundle campaigns. The combination of custom fields (gift notes, date pickers, file uploads) and subscription support makes it a natural fit for gifting-focused merchants who need personalization built into the box builder flow.

EB | Easy Bundle Builder by Skai Lama

Easy Bundle Builder from Skai Lama is one of the most popular bundle apps on the Shopify App Store, with 4.9 out of 5 stars across 857 total reviews. It is built for Shopify and targets high-volume DTC brands that need deep design control and advanced discount logic.

Key features

• Easy Bundles enables customers to build their own customizable bundles and gift boxes, with fixed-price bundles, discounted bundles, bundle subscriptions, tiered discounts, and mix-and-match options.

• Multiple discount rules including tiered discounts, fixed price bundles, and free gifts, plus a developer-friendly open SDK for custom bundle builder designs.

• Instant inventory and 3PL sync, performance tracking, and revenue analytics.

• Multi-step flow support for dedicated bundle pages with expandable cards and product selection drawers.

Pricing

The app offers three tiers: Essential, Plus, and Enterprise. All plans include the same features; the only difference is the amount of revenue you can generate from bundle sales each month. Essential allows up to $7,500 in bundle sales per month, Plus allows up to $20,000, and Enterprise allows unlimited bundle sales. Paid plans range from $49 to $399 per month. A 15-day free trial is included.

Best for

Easy Bundle Builder is the right pick for high-volume DTC and Shopify Plus brands that want full design control, developer-friendly SDKs, and dedicated support. For Plus merchants, Skai Lama offers a dedicated expert in your own Slack channel, ready to handle the entire setup and tailor the app to your theme perfectly. The revenue-based pricing model means costs scale with your success, but it also means the app gets expensive quickly once your bundle sales grow.

Simple Bundles & Kits

Simple Bundles & Kits by Freshly Commerce takes a fundamentally different approach. Rather than focusing on a flashy front-end builder, it excels at the backend: when a customer buys a bundle, Simple Bundles lists each individual item (SKU) in the Shopify order, allowing warehouse staff or fulfillment centers to pick and pack items efficiently, with support for 3PLs, WMS, and shipping services like ShipStation.

Key features

• Bypasses Shopify's 2,048 variant limit with unlimited bundle options.

• Integrates with POS, ERP, WMS, and 3PL to break down bundles into individual SKUs for order fulfillment and inventory sync.

• Supports mix-and-match bundles, fixed bundles, subscription bundles, BOGO bundles, volume discounts, wholesale B2B multipacks, and more.

• Bundles can be sold through all sales channels, including Amazon, Instagram, Facebook, TikTok, Etsy, and Faire.

• AI-powered Bundle Magic turns your order data into ready-to-launch bundles in one click.

Pricing

You can launch your first bundles in minutes and create up to 3 bundles for free. Paid plans scale with your usage. Note that pricing has changed over time, so verify the current tiers directly on the app listing before committing.

Best for

Simple Bundles is the best choice for operations-heavy stores that rely on 3PL, ERP, or WMS integrations and sell across multiple channels. It powers product bundles and kits for brands of all sizes, from growing startups to industry leaders, scaling seamlessly across sales channels and fulfillment centers. The trade-off is that its front-end build-a-box experience is more minimal compared to apps like Biscuits Bundles, Boxi, or Easify that focus on the customer-facing picker.

How to choose

Your best pick depends on which layer of the bundling stack matters most to your business. Here is a simple decision framework:

Start with your inventory and fulfillment model. If you use a 3PL, ERP, or sell on multiple channels (Amazon, Faire, POS), Simple Bundles & Kits is the strongest choice because it breaks bundles into individual SKUs at the order level. If you want Shopify's native bundle system handling inventory with zero middleware, Biscuits Bundles is the cleanest path.

Then evaluate your front-end needs. If you want a polished multi-step wizard with volume discount tiers and minimal setup, Biscuits Bundles or Boxi will get you live fastest. If you need 30+ templates, custom fields like gift messages and file uploads, or subscription box support, Easify Box Builder covers the most ground. If you are a Shopify Plus brand that needs open SDKs for fully custom designs and dedicated account management, Easy Bundle Builder by Skai Lama is purpose-built for that tier.

Finally, consider subscriptions. If recurring build-a-box orders are core to your model (think monthly snack boxes or beauty samplers), check that your chosen app integrates with your subscription provider. Easify, Easy Bundle Builder, and Simple Bundles all support subscription bundles. Biscuits Bundles does not support subscriptions or purchase options at this time.

Tip - Every app on this list offers a free plan or a free trial. Install your top two contenders, build the same box in each, and test the customer experience on mobile before making a final decision. The checkout and cart experience often varies more than you would expect between apps.
