Virtual Inventory in practice

See how a Shopify store can use Soply Virtual Inventory when products share materials, Shopify tracks a material's stock, a kit depends on components, or an order needs to reserve inventory. Each use case starts with a business problem and example quantities, then shows the Soply configuration and the result to verify.

These are illustrative scenarios, not customer testimonials or reported merchant results. Use the linked tutorials for step-by-step instructions in the app.

Raw materials and made-to-order products

• Manage shared fabric across T-shirt variants: Give sizes different fabric usage while they draw from one material pool.
• Track made-to-order candles with a multi-level BOM: Find the ingredient that limits production through a sub-assembly.
• Sell made-to-order products when materials run short: Measure a material shortfall before allowing backorders and follow up on shortage orders.
• Ship ready-made shirts before using fabric for new orders: Keep pre-produced stock separate from material-derived availability and check consumption priority.
• Reorder critical ingredients before production stops: Set a material-specific threshold for an ingredient with a longer replenishment time.

Shopify stock sources, sync, and cart validation

• Sell bead packs and handmade bracelets from one stock source: Use a Shopify variant's stock as the source for a material consumed by another product.
• Keep a handmade product's Shopify stock in sync with its materials: Preview and verify a material-based quantity before writing it to a sales variant.
• Prevent a mixed cart from overselling shared fabric: Check the combined material requirement of two individually available products.
• Manage one raw material across two Shopify warehouses: Compare summed and lowest-location stock rules against how the store fulfills orders.

Bundles and multiple Shopify locations

• Calculate gift box availability from component stock: Find the maximum complete kits supported by beans, mugs, and spoons.
• Find out why a bundle is out of stock across locations: See why component totals cannot replace a location-by-location kit calculation.

Orders and inventory reservations

• Reserve inventory for cash on delivery orders: Follow a pending COD order from reservation to payment, deduction, or cancellation.

Choose a starting point

If each sale consumes a measured amount of material, begin with the shared-fabric case. If customers buy a fixed set of existing products, begin with the gift-box case. If the number looks right before checkout but changes after an order, begin with the COD reservation case and review the store's order timing rule.

The example calculations assume no other stock constraints unless a page says otherwise. Before applying one to a live store, verify the relevant material's Available to use, component stock by location, product bindings, inventory mode, and purchase validation status.
