No, Zoho Desk does not include native asset management as a built-in module. This remains true today, though the options for adding asset tracking around Zoho Desk have expanded considerably since this was first asked.
Zoho Creator offers dedicated IT Asset Management solutions and templates, letting you build a custom asset database covering hardware, software, and network devices, with a full asset lifecycle from procurement through to disposal, a central configuration management database, and check-in/check-out tracking with an audit log. Since Creator apps can connect to Zoho Desk, custom fields and modules built this way can be linked back to tickets, contacts, and accounts.
If your use case is tracking assets that belong to your customers, such as installed equipment needing service and maintenance, Zoho FSM (Field Service Management) includes a dedicated Asset Management module covering service history, warranty periods, maintenance schedules, and linked service requests, estimates, and work orders.
For organisations needing a fuller IT service management platform with asset management and a configuration management database built in from the ground up, ManageEngine ServiceDesk Plus, also part of the Zoho family of products, combines ITSM, IT asset management, and enterprise service management for departments beyond IT.
If you already track assets in a custom Zoho CRM module, you can associate assets with Accounts and Contacts there, and reference that same asset information from within Zoho Desk tickets via the CRM integration, letting agents see which specific asset a ticket relates to without a dedicated Desk-side asset module.
