Quick IT Tips
Practical advice for Sussex businesses — whether you work with us or not.
- •Create a hardware inventory spreadsheet for every device in your Sussex office — include purchase date, warranty expiration, and assigned user. When something fails, you'll know immediately whether it's worth repairing or replacing.
- •Plan hardware replacements proactively. Business workstations have a 4-5 year productive lifespan. If your Sussex office is running machines older than that, you're spending more on lost productivity than a replacement would cost.
- •When retiring old equipment, don't just delete files and donate the machine. Use proper data wiping tools or have your IT provider handle it. A simple delete doesn't actually remove data from the drive.
- •Keep a record of all software licenses your Sussex business uses — including subscription renewal dates and how many seats you're paying for versus actually using. License waste adds up quietly.
- •If your current IT provider doesn't do quarterly reviews of your technology environment, you're operating reactively. Proactive planning catches aging equipment and security gaps before they become emergencies.
