IT budget for a small business: what to plan for

A small business IT budget is often built up piece by piece: a license invoice here, a computer replaced in a hurry there, a project decided halfway through the year. The result is hard to read and full of surprises, especially when several devices reach end of life at the same time.

A useful IT budget does not try to be accurate to the last franc. It lists the line items, separates what comes back every year from what happens once, and anticipates renewals. The amounts depend on your size, your sector and your choices: this guide gives no figures, only a structure.

What should an IT budget include?

A complete budget covers seven families of spending. Some are visible, others only show up on the day they are missing.

• Licenses and subscriptions: Microsoft 365, business software, security tools, domain names and certificates.
• Hardware and renewal: workstations, monitors, printers, servers, firewalls, Wi-Fi access points and phones.
• Support and managed services: the provider's flat fee or the in-house IT person's time, plus work outside the flat fee.
• Security: endpoint protection (EDR), e-mail filtering, multi-factor authentication, staff awareness training.
• Backup: storage for the copies, an off-site copy and restore tests.
• Projects: migration, office move, new business application, network overhaul.
• Training: getting started with tools, security awareness, upskilling the go-to people.

Recurring vs one-off IT costs: how to tell them apart?

Recurring costs come back every month or every year: subscriptions, licenses, the support flat fee, backup storage. They mostly change with the number of users, which makes them predictable.

One-off expenses happen once: a hardware purchase, a project, an exceptional intervention. These are the ones that cause surprises. Hardware sits in between: each purchase is one-off, but renewing the fleet comes back regularly and is best planned like a recurring cost.

Planning the IT budget over 3 to 5 years

A multi-year plan avoids replacing the entire fleet in the same year. Start from the inventory: for each device, note its purchase date, its warranty end date and when support for its operating system ends. The busy years then become visible, and you can spread the replacements out.

Then add the known deadlines: contract renewals, end of support for a piece of software, planned projects. The plan is reviewed every year; it does not lock anything in.

• An up-to-date hardware inventory, with purchase and warranty end dates.
• The list of contracts and subscriptions, with their renewal dates and notice periods.
• End-of-support dates announced by vendors, such as Windows 10 in October 2025.
• Planned projects, even roughly, with the year in view.

The costs that are often forgotten

• Licenses still being paid for people who have left.
• Staff time lost during a migration or an outage.
• Repairing a critical computer that fails out of warranty.
• Restore tests, which take time even when everything is fine.
• Documentation, without which every intervention takes longer.

Keeping the budget alive

An IT budget is compared with reality every year: invoices, incidents, projects completed or postponed. The gaps show where to adjust. Where fleet management is part of your contract, SysPros keeps the inventory and the deadlines it covers up to date and can prepare with you an overview of upcoming renewals, which you then put figures on according to your priorities.
