IT budget planning for a small business: what should you include?

Start your IT budget with the technology the business already depends on. Separate recurring running costs, planned device replacement, improvement projects and contingency. Give each item an owner, a likely cost and a decision date, so the budget shows when action is needed as well as what you might spend.

You do not need a complicated model to begin. A clear list of current commitments and upcoming decisions is more useful than a single annual figure with no explanation behind it.

This IT budget planning guide includes a blank worksheet you can copy. It is a planning aid, not a quotation, an industry spending benchmark or personalised accounting advice.

Find the commitments before adding new ideas

Collect recent invoices, contracts, renewal notices and a simple list of users, devices and business applications. Ask who owns each service and whether it is still needed.

Include email and Microsoft 365 licences, connectivity, support, security, backup, specialist software, website services and other systems the team relies on. Your business may have additional items; the point is to identify the actual commitments rather than copy another company’s shopping list.

Check what is bundled together. A managed service might already contain some protection or backup work, while licences or larger changes remain separate. Counting the whole bundle and each included component again makes the budget look more expensive than it is. Leaving an excluded component out does the opposite.

For support, our guide to comparing IT support costs explains why scope matters. Use your actual agreement and current quotes for the numbers in your own plan.

Use four practical cost buckets

The categories below are an editorial way to organise a budget. They are not a required accounting treatment.

1. Running the current setup

List the recurring services that keep people working: licences, support, security, connectivity and relevant business applications. Record the quantity, billing period, contract commitment and renewal or notice date.

A monthly payment does not necessarily mean a service can be cancelled monthly. Check the agreement rather than inferring the commitment from the invoice frequency.

2. Replacing and maintaining equipment

Record devices or infrastructure likely to need attention. Consider condition, reliability, support status, suitability for the job and any known warranty or support dates.

Include setup, transfer of work, necessary accessories and appropriate disposal arrangements when getting a replacement estimate. The purchase price alone may not describe the whole job. Avoid assuming every laptop must be replaced at the same age.

3. Projects and business changes

Allow for planned hires, a move, a migration, new software or another improvement the business has actually prioritised. Include implementation, training and the staff time needed to make the change work.

Keep proposed projects visible but distinguish an approved commitment from an idea. A rough estimate should be labelled as such, with a person responsible for obtaining a firmer figure.

4. Contingency

Discuss what would happen if an important device failed, a project needed extra work or another plausible unplanned need arose. Decide on a sensible allowance and how spending from it would be approved.

There is no universal percentage in this worksheet. The amount should reflect your circumstances and the uncertainties you have identified, with input from the people responsible for the business’s finances.

IT budget planning: your worksheet

Use one record per service, replacement or project. Duplicate it as often as needed, then group the records under the four buckets.

• Item and business purpose: ______

• Bucket: running costs / equipment / projects / contingency

• Owner and supplier, where applicable: ______

• Quantity or scope: ______

• Amount and currency: ______

• VAT included or excluded in this figure: ______

• One-off or recurring, and billing period: ______

• Estimate, quotation or committed cost: ______

• Payment, renewal or notice date: ______

• Decision needed by, and who approves it: ______

• Included elsewhere or dependent on another item: ______

• Next action and date: ______

Then add a summary for the period you are planning:

• Planning period and date last checked: ______

• Recurring running costs for that period: ______

• Planned equipment spending: ______

• Approved projects and separately listed proposals: ______

• Contingency allowance: ______

• Total planned spending and remaining uncertainties: ______

Use a consistent currency, time period and VAT basis when adding figures. Ask your accountant how the plan should connect to your accounts or cash-flow forecast. Do not mix a full annual subscription with one month of another service and call the result an annual total.

Put the decisions on a calendar

The payment date may be too late to make a useful decision. Record any notice deadline and work backwards to allow time for review, approval, ordering and setup.

Hypothetical example, using invented dates: a five-seat business application renews on 1 July, with notice due by 1 June. Four people use it now. The office manager checks the renewal notice and staff plan; the business owner confirms that a June starter needs the fifth seat. The planning record reads:

• Owner: office manager.

• Quantity: five seats.

• Cost: unknown; supplier quote needed by 8 May.

• Renewal decision: business owner by 15 May, after checking the contract term and asking the finance owner to confirm the quote’s VAT basis.

• Seat decision: retain the fifth seat for the confirmed starter.

Renewal spending remains unapproved until those checks are complete. The apparently unused licence therefore stays in the plan for a known need, with the missing cost and approval deadline visible.

These dates are illustrative; actual notice periods and setup times must come from the agreement and supplier.

Record dependencies too. If a replacement device must run specialist software, confirm compatibility and the transfer arrangements before ordering it. If a project depends on staff training, that training belongs in the plan.

Copy this rolling-calendar entry for each upcoming commitment:

• Item and owner: ______

• Renewal or payment date: ______

• Contractual notice deadline, if applicable: ______

• Decision and approval needed by: ______

• Setup or delivery lead time to confirm: ______

• Next action and responsible person: ______

Keep this short view beside the annual totals so approaching choices are easy to see.

Prioritise without weakening the foundations

First identify the spending needed to keep essential work supported and appropriately protected. Then look for genuine waste, such as an unused service, but check dependencies and any data or contractual consequences before cancelling anything.

After that, assess proposed improvements against a clear business problem. What will change, who will use it, what will it cost to adopt and how will you judge whether it helped?

Our 90-day IT strategy guide helps turn a priority into a manageable next step. The budget’s job is to make its cost and timing visible alongside the existing commitments.

Review when the business changes

Set a regular review point, such as a quarterly check, and revisit the plan when a material change occurs. Ask whether headcount, devices, applications, service scope or project assumptions have changed.

Compare planned spending with what actually happened. Update estimates, record new commitments and carry forward decisions that still need an owner. Keep the reason for a change, so the next review does not become a fresh investigation.
