What is IT budget planning?

In one line
Dividing next year’s IT spending into items such as servers, software subscriptions, labor, and outsourcing, and budgeting each as an operating cost or an investment cost. The training team’s LMS and collaboration tool subscriptions belong here too.

⚡ Summary in 3 lines
  • It starts with gathering scattered subscriptions onto one page
  • Operating costs auto-renew; investments need approval
  • A budget without a renewal calendar won’t match what actually gets billed

The first thing that changes once you start building a separate IT budget is that you can see where the money leaks. At many companies, IT costs are scattered across general administration, supplies, and department operating budgets, so no one knows the total until it is added up at year-end. Once the items are gathered on one sheet, money that leaves automatically every year, such as subscriptions and maintenance fees, separates from one-time investment costs, and only then can you discuss what to cut and what to protect. The training team’s LMS, survey tool, and AI tool subscriptions should also go on this sheet so that next year’s training budget and IT budget don’t push costs onto each other.

Items are divided broadly into operating costs and investments. Operating costs include SaaS subscription fees, cloud usage fees, telecom lines, maintenance contracts, and IT staffing and outsourcing costs. Investments include equipment purchases such as servers and laptops, plus system build costs. In accounting, investments are recorded as assets and depreciated over several years, while operating costs end as expenses in the year incurred. So even when you buy the same capability, the financial statements look different depending on whether you subscribe or build. Another axis is the ratio of 'keeping the lights on' to 'new initiatives.' If you split the total IT budget into how much goes to maintaining current systems and how much remains for work starting next year, you can answer the question executives care about most: 'So what changes next year?'

The usual sequence is to collect departmental needs in October, have the IT department do a technical review and remove duplicates in November, and reconcile the total with finance in December. Alongside this, you must also build a license and contract expiration calendar. Only when it records which subscription auto-renews in which month, and when the cancellation notice deadline falls, will your budget and actual payments stay aligned. For overseas SaaS paid in dollars, write down your exchange-rate assumption, and for per-user pricing, set the number of seats to match next year’s headcount plan.

The most common slip in practice is leaving small subscriptions out of the budget. If each department has one tool at KRW 30,000 (≈ US$22) a month, it adds up to tens of millions of won by year-end, and payments nobody can explain stay on the corporate card statement. It is also common that no one reviews auto-renewing operating costs while investment costs get careful scrutiny because they need approval. On the training team, if an AI tool or survey tool is paid for on a personal card and the owner changes, the account and its data disappear together. Remember that the company doesn’t protect tools that aren’t in the budget.

💡 In plain English
It’s like sorting out your household fixed expenses: you start by listing the auto-pay subscriptions before the rent.
Why it matters in practice
If you don’t decide now which budget pays for the LMS and AI tool subscriptions in next year’s training plan, payments will stall in January or the training budget will take the hit.
Origin and sources

The practice of managing IT costs as a separate line in corporate budgets took hold as investment in information systems grew. Since the 2010s, as software has shifted from purchase to subscription, the weight of IT budgets has moved from investment costs to operating costs, and this shift is changing how budgets are built in the first place.

An example

Take a hypothetical example. Company A, a food distributor with 350 employees, had a KRW 900 million (≈ US$673,400) IT budget last year, but the SaaS subscriptions that departments paid for separately were not totaled anywhere. Before October budgeting, the finance director asked for a one-page view of what the company actually spends on IT.

  1. Manager Park on the IT team pulled every software charge from 12 months of corporate card statements. For the first time, the numbers were clear: 27 subscriptions scattered across departments, totaling KRW 64 million (≈ US$47,900) a year.
  2. After splitting the items into operating costs and investments, operating costs made up 71% of the total. The finance director said, 'I had no idea this much money went out automatically every year,' and suggested building a renewal calendar together.
  3. The KRW 18 million (≈ US$13,500) LMS subscription requested by the training team went into the training budget rather than the IT budget, with the IT team handling the security review. The two team leads co-signed the approval request.
  4. The 6 dollar-denominated subscriptions were budgeted with the exchange-rate assumption written into the approval request. For per-user tools, seats were added up front to cover next year’s plan to hire 20 people.
  5. After canceling 4 duplicate tools and running the renewal calendar, next year’s IT budget rose to KRW 940 (≈ US$1) million, but subscriptions fell by KRW 21 million (≈ US$15,700), leaving KRW 120 million (≈ US$89,800) more to spend on new investment.

FAQ

It differs by company, but the rule is to book each cost in 'one place only'. A common approach is to keep the cost in the budget of the department that uses it and have the IT department handle security and contract review. If both teams write down their roles at the approval stage, you avoid payments getting blocked at the start of the year.
Because accounting treatment and approval criteria differ. Investments are recorded as assets and become expenses over several years, while operating costs end in the year incurred, so the same amount hits profit and loss at different times. Executives need to know that as subscriptions grow, the share of operating costs rises and more money goes out automatically every year.
It is fast, but duplicate subscriptions and unused tools get carried over as they are. At the very least, review subscription items one by one based on usage rates. If a full zero-based approach is hard, a realistic compromise is to apply it to operating costs alone.
For subscriptions paid in US dollars, the usual practice is to record the KRW conversion assumption in the approval request and cover any shortfall at payment from a contingency reserve. If the assumed exchange rate is left out, it is hard to explain mid-year why spending ran over budget.
