Do You Know What You Own?
Most SMEs cannot answer a simple question: how many devices are connected to your network right now? IT asset management (ITAM) is the practice of tracking every piece of technology your business owns or uses — hardware, software, licences, and subscriptions. Without it, you are flying blind.
Poor asset management leads to wasted money on unused software licences, security vulnerabilities from untracked devices, compliance failures when auditors ask for proof of licensing, unplanned downtime when hardware fails unexpectedly, and difficulty scaling because you do not know what you have or what you need.
What Counts as an IT Asset?
An IT asset is anything with a digital component that your business relies on. This includes hardware such as laptops, desktops, monitors, printers, servers, network switches, routers, firewalls, mobile phones, and tablets. Software includes operating system licences, Microsoft 365 subscriptions, line-of-business applications, security tools, and cloud service subscriptions. Network infrastructure covers access points, cabling, UPS systems, and IoT devices (cameras, sensors, smart locks).
If it connects to your network, stores data, or supports business operations, it belongs in your asset register.
Building Your Asset Register
An asset register does not need to be complex. A well-maintained spreadsheet works for businesses with fewer than 50 devices. For each asset, record the asset tag or serial number, device type and model, purchase date and warranty expiry, assigned user or location, operating system and version, installed software, and current status (active, in storage, decommissioned).
For larger businesses or those wanting automation, dedicated ITAM tools like Snipe-IT (open source), Lansweeper, or the asset management features in your RMM platform provide automated discovery, licence tracking, and reporting.
Hardware Lifecycle Management
Every piece of hardware has a useful life. Laptops typically last three to four years in a business environment. Servers last four to five years. Network equipment lasts five to seven years. Running hardware beyond its useful life increases failure risk, reduces productivity (slow devices frustrate staff), and creates security vulnerabilities when the manufacturer stops providing updates.
Plan replacements proactively. Review your asset register quarterly and identify devices approaching end-of-life. Budget for replacements in advance rather than reacting to failures. A rolling replacement program — replacing 25 per cent of your fleet annually — spreads the cost and prevents a situation where everything needs replacing at once.
Software Licence Management
Software licensing is where asset management saves real money. Common waste includes paying for Microsoft 365 licences assigned to departed staff, maintaining subscriptions to tools nobody uses, running different licence tiers when a cheaper one would suffice, and being out of compliance with software agreements (risking audit penalties).
Conduct a licence audit every six months. Compare active subscriptions against active users and usage data. Remove unused licences, downgrade where appropriate, and ensure every licence is allocated to a current employee.
Microsoft 365 Admin Centre provides usage reports that show which users are actively using their assigned services. If a user has not accessed Teams, SharePoint, or Exchange in 90 days, investigate whether they still need the licence.
Disposal and Data Security
When an asset reaches end-of-life, it must be disposed of securely. Hard drives and SSDs contain business data that persists after deletion. Secure disposal methods include certified data destruction (physical shredding of drives), cryptographic erasure (for self-encrypting drives), and NIST 800-88 compliant overwriting. Obtain a certificate of destruction for compliance records. Never dispose of old equipment by simply putting it in the bin or donating it without wiping the data.
ITAM and Security
You cannot secure what you do not know exists. Asset management directly supports security by ensuring every device is accounted for in your endpoint protection and patch management, identifying rogue or unauthorised devices on your network, tracking software versions to confirm all systems are patched and current, and providing the inventory needed for incident response (if a vulnerability is announced, which devices are affected?).
The ASD Essential Eight includes application and OS patching as key controls. Both require a comprehensive asset inventory to implement effectively.
ITAM for Growing Businesses
As your business grows, ad hoc asset management breaks down. The jump from 10 to 50 employees is where most businesses lose track. Implement a formal ITAM process early — it is far easier to maintain a register from the start than to reconstruct one after years of untracked growth.
Integrate asset management into your onboarding and offboarding processes. Every new starter triggers an asset allocation. Every departure triggers an asset return and licence review.
