Inventory Types

Inventory Types in Resgrid define the categories of items your department tracks in the inventory system. Each type represents a class of supply or equipment — such as "SCBA Bottles", "Medical Supplies", "Hose Sections", or "Batteries" — and includes configuration for units of measure and expiration tracking.

Why Inventory Types Matter

Before you can track inventory in Resgrid, you must define what kinds of items you want to track. Inventory Types provide the classification system that organizes your supplies and equipment. They enable consistent tracking across stations, allow for expiration monitoring on perishable items (like medical supplies), and provide the foundation for inventory adjustments and reporting.

Scope

Inventory Types are department-wide. Once defined, a type can be used to track inventory at any station or assigned to any unit in the department. All personnel with inventory permissions can view and adjust inventory for any type.

Viewing Inventory Types

Navigate to Inventory → Manage Types to see all inventory types defined for your department. The list shows each type's name, description, unit of measure, and expiration settings.

Creating an Inventory Type

Click Add Type to create a new inventory type.

Field	Required	Default	Description
Type (Name)	Yes	—	The name of the inventory type (e.g., "SCBA Bottles")
Description	No	—	A description of what this inventory type represents
Expires Days	No	0	Number of days until items of this type expire (0 = no expiry)
Unit of Measure	No	—	The unit used to measure this item (e.g., "Each", "Box", "Gallon")

Expiration Tracking

Set Expires Days for items that have a shelf life, such as medical supplies, batteries, or food rations. The system will track expiration based on the date of each inventory adjustment. A value of 0 means the item does not expire.

Editing an Inventory Type

Click on an existing type to edit its name, description, expiration days, or unit of measure. Changes to the type definition affect how new inventory adjustments are categorized but do not retroactively change existing inventory records.

Deleting an Inventory Type

Inventory types can be deleted from the Manage Types page. Deleting a type does not delete existing inventory records associated with it, but no new adjustments can be made for the deleted type.

Making Inventory Adjustments

Once inventory types are defined, personnel can create inventory adjustments (transactions) to track additions and subtractions.

Navigate to Inventory → Adjust to create a new adjustment.

Field	Required	Description
Type	Yes	The inventory type being adjusted
Group	Yes	The station/group where the inventory is located
Amount	Yes	The quantity to add (positive) or subtract (negative); cannot be 0
Batch	No	A batch identifier for tracking lots or shipments
Unit	No	Optionally assign the inventory to a specific unit

Non-Zero Amount

The adjustment amount must be a non-zero value. Positive values add inventory, negative values subtract it. An amount of 0 will be rejected.

Viewing Inventory

The Inventory page provides multiple views:

View	Description
