The CFO’s dilemma: balancing control and simplicity in spend management

Finance teams don’t lose control because they lack systems—they lose it because they have too many. When spend data is fragmented across tools, visibility disappears and decisions become reactive. This is the reality of tool sprawl in finance. The solution isn’t adding more software, but orchestrating spend into one system that employees actually use.

As Robbie mentions in the interview:

You could end up with six or seven tools across the purchase ledger… for me personally, I see that as overkill in many organisations.

Finance leaders often believe that stronger control comes from adding more structure, more approvals, and more systems. In reality, the opposite is true, and this is where many CFOs quietly lose grip on spend without realizing it. You can have best-in-class tools across procurement, AP automation, expenses, cards, and subscriptions, yet still lack a clear picture of where money is going until it is too late to act.

This is the core dilemma: the more complex your finance stack becomes, the harder it is for employees to follow it, and the less control you actually have. What looks like governance on paper turns into fragmentation in practice, and fragmentation is what breaks visibility, accountability, and ultimately cost control. In many cases, this fragmentation is a direct result of tool sprawl in finance.

The insight most finance leaders miss is this: control is not created by systems alone, but by adoption. If employees do not consistently use the systems you put in place, the controls inside those systems simply do not exist in reality. This is why finance today does not need more integrations between tools, but true orchestration of the entire spend lifecycle in one place.

In the video below, Robbie Hadfield, GM of Travel and Expenses at Payhawk and former finance leader, shares how finance teams actually lose control as they scale and why adding more tools makes the problem worse instead of better. He explains how different types of spend require different control mechanisms, why procurement processes naturally evolve with company growth, and how AI can orchestrate the entire lifecycle from request to payment. Watch now, or continue reading to break down the key insights and see how to fix fragmented spend management.

The hidden problem: tool sprawl is breaking finance

In most organisations, spend management is not handled in a single system but across multiple disconnected tools that were added over time to solve specific problems. What starts as a practical decision quickly turns into a structural issue as finance teams scale and processes become more complex. This is a classic example of tool sprawl in finance and broader finance tool sprawl driven by disconnected finance tools.

A typical setup often includes:

• a procurement or PO system for supplier purchases
• an AP automation tool for invoice processing
• an expense management solution for employee spend
• a card provider for company cards

Each of these tools works well in isolation, but together they create friction for employees and fragmentation for finance. Instead of improving control, they introduce gaps where spend can happen outside of structured processes, making it harder to enforce policies and maintain visibility across a fragmented finance stack.

Why more tools mean less control

It is a common assumption that adding more systems increases governance, but in practice it reduces it because control depends on consistent usage, not theoretical coverage. The more systems employees have to navigate, the more likely they are to bypass them or use them incorrectly, which is a direct outcome of tool sprawl.

This creates three fundamental problems:

• employees struggle to adopt processes across multiple systems and revert to informal channels like Slack or email
• data becomes fragmented, making it difficult to track actual versus budget in real time
• finance teams rely on month-end close to understand spend, which makes them reactive by design

As Robbie highlights in the interview:

It’s much harder to then create a real time visibility of actual versus budget.

Even in organisations with fast close cycles, the insight comes too late because overspend has already happened. At that point, finance is no longer controlling spend but simply reporting on it after the fact, a common symptom of finance tech stack complexity and tool sprawl in finance.

The real goal: proactive, not reactive finance

The most effective finance teams are not focused on processing spend efficiently, but on controlling it before it happens. This is where two principles become critical and define the future of modern finance operations.

Those principles are:

• proactive approval of spend at the moment a decision is made
• continuous visibility of actual versus budget in real time

When these are in place, finance shifts from a reporting function to a decision-making function that actively shapes business outcomes. However, both principles depend on one condition: employees must actually use the system that enforces them.

This shift reflects a broader market trend: Deloitte’s 2026 Finance Trends report found that more than half of finance leaders (57%) are now among the top leaders influencing strategy development across their organisation.

Why simplicity drives better control

The relationship between simplicity and control is often misunderstood, but it is one of the most important insights for any CFO trying to scale finance operations. When processes are too complex, compliance drops, and when compliance drops, control disappears regardless of how sophisticated the system is.

Employees should not be expected to understand finance processes or decide which system to use for each type of spend. Instead, they should have a simple entry point, whether that is a mobile app, Slack, or another familiar interface, and the system should handle the routing automatically based on policy.

This is where orchestration becomes critical, because it allows finance to define rules and controls centrally while reducing finance tech stack complexity and keeping the employee experience simple and intuitive. The less friction at the point of entry, the higher the adoption, and the higher the adoption, the stronger the control.

Not all spend should be treated the same

One of the reasons complexity increases in finance systems is the attempt to apply a single process to all types of spend, even though different categories carry different risks and require different control mechanisms. Treating everything the same creates unnecessary friction in some areas while leaving gaps in others.

In reality, spend categories behave differently:

• travel and expenses are typically controlled through policies and limits, with a focus on preventing out-of-policy spend
• subscriptions require visibility and ownership to avoid cost creep, duplication, and underutilisation
• procurement and PO-based spend are driven by budgets, contracts, and supplier relationships

Understanding these differences allows finance teams to apply the right level of control without overcomplicating the process. The goal is not standardisation for its own sake, but alignment between risk and control.

As Robbie explains in the interview:

Based on the type of spend, the risks change, the methods of controls change, so therefore you need a different framework to control that spend within.

The practical approach: consolidate without oversimplifying

The solution to fragmented spend management is not to remove systems entirely, but to bring them together into a single orchestrated platform that supports multiple control mechanisms. This approach allows finance teams to maintain flexibility while regaining visibility and control.

In practice, this means reducing the number of tools employees interact with while centralising data and workflows in one place, eliminating disconnected finance tools and reducing tool sprawl. Low-value purchases can be handled through lightweight card-based flows, while higher-risk spend can go through structured procurement processes with approvals and budget checks.

The key is that employees do not need to think about the process itself, because the system determines the correct path based on predefined policies. This removes decision fatigue for employees while ensuring consistent control for finance.

The role of AI: making control invisible

AI has the potential to fundamentally improve how finance processes are executed by reducing friction across the entire lifecycle of spend management. Instead of relying on manual data entry and rigid workflows, AI can assist at every step from initial request to final payment.

That growing strategic role is also shaping investment decisions: PwC’s May 2025 Pulse Survey found that 58% of CFOs are investing in AI and advanced analytics to adjust planning in today’s volatile environment.

It can help employees submit complete and accurate purchase requests without needing to understand finance requirements, assist procurement teams in evaluating vendors, and automate approvals based on predefined rules. It can also improve invoice matching by analysing unstructured data and detecting anomalies that traditional systems might miss.

This shifts finance from enforcing processes to designing intelligent systems that guide behaviour, making control more effective while requiring less effort from both employees and finance teams.

How to spot tool sprawl before it breaks spend control

Tool sprawl rarely becomes obvious overnight. It builds gradually as new systems are added to solve individual problems, until finance teams start losing visibility and control without a clear root cause. Recognising the early signals can help you act before fragmentation turns into a structural issue.

Here are four warning signs to watch for:

• Finance only sees spend at month-end
  If visibility depends on closing the books, control is already reactive. By the time insights are available, overspend has already happened.
• Employees switch between multiple systems
  When submitting a purchase, uploading a receipt, or checking a budget requires navigating different tools, adoption drops and workarounds increase.
• Approvals happen in Slack or email
  If managers approve spend outside official systems, policies become unenforceable and audit trails break down.
• Budget vs actual reporting is delayed or incomplete
  When data lives in disconnected systems, finance cannot get a reliable, real-time view of spend against budget.

If any of these signals sound familiar, the issue is not a lack of controls, but a lack of orchestration.

The new finance operating model

The shift that finance leaders need to make is not about choosing between control and simplicity, but about recognising that one depends on the other. Fragmented systems create complexity, complexity reduces adoption, and low adoption destroys control.

Modern finance teams are moving towards an operating model that is proactive, consolidated, and intuitive, where decisions are made at the point of spend and visibility exists in real time. This is only possible when systems are orchestrated into a single experience that employees actually use.

The realisation for CFOs is clear once you see it: you do not lose control because you lack tools, you lose control because your tools are not working together. Fixing that is not about adding more software, but about orchestrating everything into one system that delivers enterprise-grade control without enterprise-level complexity.
