# Aisles, Racks, Shelves & Bins
Aisles, Racks, Shelves, and Bins describe physical storage locations inside a warehouse as a four-level hierarchy — Aisle → Rack → Shelf → Bin. Bins are the lowest level and can be tagged on stock so you know exactly where an item is kept.
Overview & List Views
A warehouse racking system stores materials in horizontal rows with multiple levels, helping you use space efficiently and organise stock for faster operations. Freespace models this as four master-data levels, each on its own screen under Inventory → Settings:
- Aisles — top level, a row in the warehouse.
- Racks — sit within an aisle.
- Shelves — sit within a rack.
- Bins — the smallest unit, sitting on a shelf; this is what gets tagged to stock.
Each level is optional and independent — you can create only the levels you need. Linking each item to its parent (rack to aisle, shelf to rack, bin to shelf) builds the full location path.
All four levels share the same list pattern:
List columns (all levels)
| **Column** | **Description** |
|------------|-----------------|
| Id | Record ID. |
| Name | Location name at this level. |
| Parent | Center (Aisles), Aisle (Racks), Rack (Shelves), or Shelf (Bins). |
Advanced filters (all levels)
| **Filter** | **Description** |

Quick Start
1. Create top-down
For a complete location path, create an Aisle first, then a Rack under it, a Shelf under the rack, and finally a Bin under the shelf.
2. Open the level
Go to Inventory → Settings → Aisles (or Racks, Shelves, Bins) and click New.
3. Fill and save
Enter the Name, choose the parent location if applicable, and click Save.
Aisle
Go to Inventory → Settings → Aisles. An aisle is a row in the warehouse racking layout.
| **Field** | **Description** |
|-----------|-----------------|
| Name * | Unique aisle name. |
| Center | Optional. The location/center this aisle belongs to when you operate multiple centers. |
Rack
Go to Inventory → Settings → Racks. A rack sits within an aisle.
| **Field** | **Description** |
|-----------|-----------------|
| Name * | Unique rack name. |
| Inventory Aisle | Optional. The aisle this rack belongs to. |
Shelf
Go to Inventory → Settings → Shelves. A shelf sits within a rack.
| **Field** | **Description** |
|-----------|-----------------|
| Name * | Unique shelf name. |

| **Field** | **Description** |

Once bins exist, the Inventory Bin field can be shown on item lines and labels. Enable it under Inventory Settings.

FAQ
Do I have to create all four levels?
No. Each level is optional. Many companies use only bins, or only racks and bins. Create the levels that match how your warehouse is organised.
Is the parent link required?
No. The aisle on a rack, rack on a shelf, and shelf on a bin are all optional. Linking them builds the full location path for clearer organisation.
Where does the bin get used?
After enabling the Inventory Bin line field in Inventory Settings, you can tag bins on transaction item lines and on printed labels.
Why can't I delete a location?
Locations referenced by stock or child locations cannot be deleted. Suspend them instead.
Why is my bin missing from a transaction line?
Bin dropdowns may list only bins that currently hold stock for the selected item and center.
What must I enable before using bins on lines?
Turn on warehouse bin tracking for the company and enable Inventory Bin under item line fields in Inventory Settings.
