Technology spend deserves scrutiny. It shapes how quickly a business can move, and poor decisions can remain embedded for years. CFOs are right to ask whether it is controlled, aligned to strategy and producing a commercial return.

That challenge should not place the CIO or technology leader in the dock. It should create a better investment conversation between finance, technology and the wider executive team. The result should be stronger decisions about where technology must run the business, enable growth and create value.

CFO scrutiny of technology spend is healthy

A good CFO should challenge technology spend in the same way they challenge investment in people, property, acquisitions or new markets. What outcome is the organisation buying? What assumptions support the decision? What will success look like, who owns it and what happens if the investment does not proceed?

Those are not hostile questions. They are the questions that turn a technology proposal into a business decision. Strong technology leaders should welcome them because challenge exposes weak assumptions early, improves prioritisation and creates shared accountability for the outcome.

The problem begins when scrutiny arrives only after costs have risen or a programme is under pressure. Technology must explain a complex estate through budget lines, while finance sees an expanding cost base with benefits that are difficult to trace. Both sides become defensive and lose sight of the original business outcome.

The strongest CFO-CIO relationships avoid that trap. They establish the commercial case before approving spend, review it as circumstances change and make trade-offs together. The CIO brings insight into capability and delivery risk; the CFO brings discipline around capital, return and affordability.

Technology leadership is not simply an overhead

Technology leadership may appear in the accounts as an overhead, but that does not describe its commercial role. Good leadership determines how the organisation allocates investment, protects operations and enables change. The cost of the leader is visible; weak leadership is hidden across suppliers, delays, duplication, failed change and missed opportunity.

Rebecca Fox made the wider case in her CIO.com article, “Why the CIO is becoming the most commercial role in the boardroom“. The best CIOs do not simply deliver systems. They connect technology decisions to revenue, margin, resilience and competitive advantage.

That commercial mindset matters when a CFO challenges spend. A strong CIO does not defend every platform or project simply because it sits within technology. They stop work that no longer matters, simplify the estate and move investment towards greater business value.

Commercial challenge can make good CIOs and technology leaders better leaders. It sharpens their case, strengthens their command of the numbers and forces clearer choices. It should increase their influence, not reduce them to defendants explaining why the budget exists.

Assess technology investment through run, grow and value

One useful way to challenge technology spend is through three lenses: run, grow and value. This is more useful than technical budget categories because it connects the portfolio to what the business must protect, change and achieve.

Run the business

Run spend keeps the organisation operating safely and reliably. It covers the platforms, support, cyber controls and data needed to serve customers, meet obligations and recover from disruption. The commercial test is whether it provides the right service and resilience at an appropriate cost.

Run costs still need challenge. Legacy contracts, underused licences and overlapping tools can consume money without improving service. Cost optimisation should release capacity and simplify the operation, not weaken essential foundations.

Grow the business

Grow spend enables the business strategy. It may support new products, markets or channels, improve customer experience or help the organisation scale without adding cost at the same rate. The investment must serve a defined growth ambition that the wider business is ready to deliver.

Technology cannot create growth in isolation. A new platform will not repair a weak proposition, unclear ownership or a process the business has not agreed to change. CFO scrutiny tests whether the whole investment case is funded, not merely the technology.

Create business value

Value spend improves the economics or strength of the organisation. It can reduce unit cost, automate work, improve decisions, strengthen resilience or build confidence ahead of investment or exit. In private equity, technology must connect directly to the value creation plan.

The value lens prevents a narrow focus on immediate savings. An investment may protect revenue, reduce exposure or create capacity without producing a simple payback next quarter. Private equity value creation depends on understanding those effects across the hold period.

ROI matters, but so does the cost of doing nothing

Every material technology investment should have a credible return case. It might be expressed through revenue, margin, lower cost, reduced risk or greater capacity. It should identify the baseline, expected benefit, timing and business owner accountable for delivery.

Rejecting an investment because the return is difficult to express does not make the alternative free. Doing nothing may mean rising support costs, operational workarounds, lost sales, weak data, cyber exposure or difficulty integrating an acquisition. Delay also allows complexity to build.

This is where simplistic ROI calculations fail. They compare the proposed investment with today’s budget, rather than the likely future cost and risk of retaining the current position. A sound decision compares credible options, including the consequences of deferral, reduction or no action.

The same discipline applies after approval. Implementation is not the outcome, so benefits must be reviewed once the technology is live. Without adoption, removal of old cost or operating change, the return will not appear.

Complexity is the hidden cost in technology spend

Technology is not always the expensive part. Poor decisions and accumulated complexity are often the real expense. Every additional platform brings licences, support, security, integrations, data, controls and people who need to understand how it works.

Each decision may have been reasonable. A business enters a market, acquires a company, launches a product or solves an urgent problem. Over time, workarounds become permanent, similar systems remain and teams spend more effort moving data than improving outcomes.

That cost rarely appears on one budget line. It shows up in slower delivery, manual reconciliation, fragile reporting and greater change risk. This is why simplicity becomes a competitive advantage: it creates speed, protects margin and makes the organisation easier to operate.

CFO challenge should ask what the business can remove as well as what it needs to buy. A cheaper contract does not solve an unnecessary system, and reducing the team may increase cost elsewhere. Strong cost decisions simplify the operating model rather than negotiate a lower price for complexity.

Having no technology strategy is still a strategy

Some organisations believe they avoid unnecessary spend by not creating a clear technology strategy. In practice, having no technology strategy is itself a strategy, usually determined by inertia, local decisions and legacy platforms.

Technology spend still happens. Contracts renew, departments buy tools, suppliers shape the roadmap and teams work around constraints. The organisation may avoid one visible investment decision while accepting a series of smaller decisions that gradually increase cost and reduce choice.

An effective technology strategy does not predict every future system. It connects business ambition to required capabilities, establishes investment principles and makes priorities explicit. The CFO, CIO and executive team can then decide what to fund, stop or consciously defer.

Without that direction, annual budget pressure tends to favour what already exists. Run costs remain protected because the business depends on them, while investment in growth and value is repeatedly deferred. Inertia wins, even when nobody deliberately chose it.

Better challenge creates better technology leadership

CFOs are right to challenge technology spend, but the quality of that challenge matters. Cutting a percentage without understanding the consequences is not commercial discipline. It can protect complexity, reduce delivery capacity and hide risk.

Better challenge starts with business strategy and assesses spend through run, grow and value. It examines lifetime cost, expected return and the cost of doing nothing. Technology enables change, but business leaders still own adoption and benefit realisation.

Useful governance makes that challenge routine rather than confrontational. A regular portfolio review should track cost, delivery, risk and benefits together, with clear decisions when assumptions change. For private equity owners and portfolio executives, the same view should connect technology priorities directly to the value creation plan and the milestones that matter across the hold period.

For CIOs and technology leaders doing the job well, this is an opportunity. Commercial scrutiny strengthens their leadership and improves investment choices. The objective is not to win a budget argument; it is to make better decisions that grow revenue, drive margin and improve resilience.
