The supplies inventory exists in GLPI, but it doesn't communicate with tickets – each manual deduction, without a link to the service that originated it, becomes a traceability gap.
The problem
Support teams consume supplies – toners, cables, parts, memory modules – during ticket service. GLPI has a native consumables module (ConsumableItem), but it has no connection with tickets. The practical result: deductions are made manually, without recording which ticket motivated the consumption, and reports remain incomplete. When it's necessary to audit the consumption for a period or track the use of a specific supply per service call, the information simply isn't there.

How Inventory works
The NexTool Inventory module creates a bidirectional bridge between tickets and GLPI's native consumables. The inventory deduction is made within the ticket, is recorded in both the ticket and the consumable, and the available balance is validated in real time before any movement.
- Inventory tab in the Ticket – the technician selects the consumable and quantity directly in the ticket, without needing to navigate to another screen.
- Output tab in the Consumable – the same movement appears in the consumable, with the linked ticket clearly displayed.
- Balance validation – before debiting, the system verifies available balance using GLPI's native calculation, preventing invalid movements.
- Native inventory deduction – records in
glpi_consumablesare automatically updated, keeping GLPI's native inventory always consistent. - Reversal with return – outputs can be reversed with one click, returning consumables to stock. The feature is configurable.
- Reports with CSV export – movement dashboard with period, consumable, and status filters, with CSV export button for spreadsheet use.
- Mandatory ticket – it's possible to configure whether every output must be mandatorily linked to a ticket, ensuring total traceability.


How to activate
- Install NexTool on your GLPI 11
- Go to Setup > NexTool > Modules
- Activate Inventory and click Configure
- Set reversal and mandatory ticket options in the Settings tab

Who is it for
The Inventory module is recommended for support and infrastructure teams that consume physical supplies during service calls and need to maintain consumption traceability per ticket. It's also useful for managers who need service cost reports and want to cross-reference supply consumption with corresponding tickets without exporting data from multiple systems.
