Bundly helps merchants increase average order value with mix and match, build your own (BYOB), build a box, and fixed bundles from existing products and collections. Set min/max selections and quantity rules, then price bundles your way: fixed price, component total, percentage off, or amount off. Inventory is tracked per product with no syncing needed, and bundles can stack with discounts. Ideal for gift boxes, kits, and curated sets. Not compatible with POS or subscription apps.
