Kits usually mean duplicate products, manual bookkeeping, and oversold components. KitBuilder builds every kit type from your existing catalog: fixed bundles, mix-and-match boxes, and tiered sizes with price breaks. Kits sell as their real component items, so Shopify decrements every part and enforces stock at checkout. Shoppers build their box in a polished picker with a live counter and visible savings. Rules keep boxes sane: minimums, maximums, duplicates. Everything is included on one flat price.
