Component inventory for Shopify
Stop overselling Shopify products that share the same parts.
StockPool tracks the components inside your kits, bundles, and multi-part products, calculates true sellable inventory, and syncs it back to Shopify automatically.

The problem
Shopify tracks products. Your inventory lives in the parts.
A single candle, bottle, insert, cable, bracket, or material can be used across dozens of Shopify products. When that shared component runs low, every product that depends on it needs to update too.
Oversold bundles
Manual edits across dozens of products
Hidden stockouts from one shared component
Confusing spreadsheets and silent sync failures
How it works
Four steps from parts to synced Shopify inventory.
Build product recipes
Choose a Shopify product and define which components it uses.
Calculate sellable inventory
The lowest available component becomes the product's sellable quantity.
Keep Shopify synced
Orders, refunds, cancellations, and manual adjustments update stock.
Inventory clarity
One candle. Multiple products. No guessing.
If Vanilla Candle drops to 0, every connected product gets updated before that one shared part causes another oversell.
Only 4 gift boxes sellable
because Vanilla Candle has 4 left.
Limiting component visibility is built into the workflow.

FAQ
Quick answers for Shopify merchants.
Is StockPool a bundle builder?
No. StockPool is focused on inventory. It tracks the components behind products and syncs sellable quantities to Shopify.
Do components have to be Shopify products?
Not always. Components can live inside StockPool, or you can link real Shopify variants when you sell those parts individually.
What happens when an order comes in?
StockPool subtracts the required components, recalculates affected products, and syncs the new sellable quantities back to Shopify.
Is this a full ERP?
No. StockPool is intentionally lightweight and focused on shared component inventory for Shopify merchants.
