See every featureFlex Bundles helps high-volume brands launch bundles that are too complex for templated apps. Build fixed, mix-and-match, build-your-own, tiered, BOGO, and subscription bundles with your own design, logic, and pricing. Bundles run natively through checkout and fulfillment as real line items, so pricing, inventory, and order data stay accurate.
Solid Bundles is the bundle app serious operations trust. Orders keep original prices with discounts allocated per line, so SAP, NetSuite and your 3PL reconcile every order cleanly. Bundles expand at checkout into real component SKUs, one clean packing line per item. It never writes to your inventory, so stock can never be corrupted. One click verifies every bundle cart in every market before customers see it.

- Native implementation with no external JS for optimal site performance.
- Fixed bundles expand into component SKUs at checkout
- Percentage quantity breaks stay exact in every currency
- One-click verification runs real test carts in every market
- Server-rendered storefront blocks, no scripts or layout shift
