My Inventory: Track the Parts You Own
User Inventory is the record of parts you already own. BrickZap uses it to calculate project progress, owned quantities, and missing quantities automatically.
You can manage your saved parts from My Inventory.
What you can do in My Inventory
- View the parts you already own
- Search by part name or SKU
- Filter by color, type, or source when available
- Add items manually
- Increase or decrease quantity quickly
- Edit or remove saved items
- Use your inventory as the basis for Projects
Inventory overview
At the top of the page, BrickZap may show summary totals such as:
- Total unique parts
- Total quantity
- Colors tracked
These totals give you a quick snapshot of your collection without turning the page into a warehouse-management tool.
Search and filters
Use the filters row to narrow your inventory:
- Search by part name, SKU, or part number
- Filter by color
- Filter by product type such as part, minifigure, or set
- Filter by source such as manual, project, or import
If no results match your filters, BrickZap will show an empty filtered state instead of reloading the page.
Add an item
Click Add Item to add a part manually.
In the add-item dialog you can:
- Search the catalog
- Pick the matching product
- Choose a color if applicable
- Enter quantity
Manual additions are typically saved with a manual source so you can distinguish them from project-linked or imported entries.
Update quantity quickly
Each inventory row or card can include fast actions such as:
- +1 to increase quantity
- -1 to decrease quantity
- Edit quantity for direct changes
- Remove item to delete the entry
These actions are designed to make quantity management fast and low-friction.
If quantity reaches zero, BrickZap may remove the item from inventory.
How inventory is matched
Inventory is tracked by:
- Catalog product
- Color, when a color is selected
That means your saved quantity is matched against the same catalog item in your project. If color matters for the build, make sure the project item and your inventory use the same color.
How inventory connects to Projects
Inventory is part of the larger build-planning workflow:
- Projects use your inventory to calculate Owned qty
- Projects calculate Missing qty from what you still need
- More accurate inventory means more accurate build progress
- Missing parts can be easier to identify before adding them to cart
How quantity works
For each matching part:
- Owned qty comes from your saved inventory
- Missing qty is calculated as
required - owned
Missing quantities are calculated when the project is loaded. They are not stored as permanent values.
Best practices
- Track colors accurately for color-sensitive builds
- Keep quantities up to date as you sort or buy parts
- Update inventory before using Add missing to cart in a project
- Keep project items tied to the correct catalog product
- Treat inventory as your source of truth for what you already have
Important note
Inventory is tied to catalog products, not seller listings. This keeps project matching stable even when marketplace listings change.
