Quick answer
Max sellable quantity is the maximum number of bundle units you can sell given current component inventory. It is typically the floor of (component available ÷ quantity consumed) across all components.
- Bundle terminology is inconsistent across Shopify — define terms before choosing an app.
- Merchandising language (kit, FBT, tier) should match what shoppers see on the product page.
- Operational terms (max sellable quantity, expanded SKUs) matter at fulfillment time.
- Kitforge uses these concepts in the admin editor and storefront widgets.
Definition
Max sellable quantity is the maximum number of bundle units you can sell given current component inventory. It is typically the floor of (component available ÷ quantity consumed) across all components.
Why it matters
Without max sellable quantity, bundles oversell when one component runs out — creating refunds, split shipments, and support tickets.
How Kitforge uses this
Kitforge recalculates max sellable quantity on inventory webhooks and enforces it at checkout via Cart Validation Functions.
- fixed kit bundles — combine known products into one priced offer
- frequently bought together (FBT) — product-page add-on recommendations
- quantity breaks — tiered volume discounts when shoppers buy more units
Final recommendation
Understanding max sellable quantity helps you choose the right bundle type and avoid checkout surprises. Apply the term when configuring Kitforge offers and when briefing your team.
If you want this kind of offer to feel native to the buying journey, Kitforge Bundles is built around that exact problem: turning related Shopify products into clearer bundle offers before the shopper reaches checkout.
