How to empower department heads with custom budget limits

As businesses grow, spending decisions become more distributed. Marketing needs to move quickly on campaigns. Sales teams need flexibility when entertaining clients. IT often has urgent purchasing needs that can’t wait for a lengthy approval chain.

But giving teams more autonomy doesn’t mean giving up financial control.

The most effective finance teams strike a balance: they decentralise day-to-day spending decisions whilst maintaining clear oversight, consistent policies and real-time visibility. That’s where custom budget limits come in.

With Pleo, you can give department heads the authority to manage their own budgets, approve routine spend and make informed decisions – all within guardrails that protect the business.

Here’s how to set it up.

Key takeaways:

• Give department heads clear ownership of their budgets without sacrificing financial oversight.
• Tailor spending limits to different teams, roles and purchasing needs.
• Automate low-value approvals so managers can focus on more significant spend.
• Track departmental budgets in real time to prevent overspending before it happens.
• Use analytics to help managers make smarter, more strategic spending decisions.

Why decentralised budget management works

Finance shouldn’t have to approve every software subscription, team lunch or travel booking.

Department heads are often closest to the context behind a purchase. They understand their team’s priorities, upcoming projects and operational needs better than anyone else. By putting spending decisions in their hands, you speed up processes and improve accountability.

At the same time, finance retains the visibility and controls needed to manage risk, ensure compliance and maintain budget discipline.

That means faster decisions, stronger accountability and a finance function that enables growth rather than slowing it down.

How to empower department heads with custom budget limits

1. Create dedicated teams for each department

The first step is to group employees into their respective departments, such as marketing, sales or IT.

In Pleo:

1. Go to the People section
2. Select Teams

Create a new team for each department. This allows you to categorise expenses and analyse spending at a departmental level, rather than just by individual employee.

2. Assign department heads as team reviewers

Once your teams are in place, assign each department head as the reviewer for their team.

This delegates day-to-day approval responsibilities to the people best placed to evaluate spending decisions. A department leader can quickly assess whether a new software tool, training course or client expense aligns with their team’s objectives.

It also frees up the finance team to focus on exceptions, policy and strategic oversight.

3. Set custom spending limits for the department

Not every department spends in the same way, so your controls shouldn’t be identical across the organisation.

Within the People tab, select a team member and navigate to Limits.

You can configure:

• Monthly or total limits to cap overall spending
• Per purchase limits for individual transactions
• Temporary limits for one-off projects, events or urgent purchases

For example, a junior marketer may need a modest per-purchase limit, whilst an IT manager may require a higher threshold for hardware or equipment purchases.

4. Implement approval thresholds

To keep spending efficient, set thresholds that determine when manual review is required.

For example:

• Expenses below £50 can be approved automatically
• Expenses above £50 are routed to the department head for review

This ensures routine, low-risk purchases move quickly whilst larger or more unusual expenses receive appropriate oversight.

It’s a simple way to reduce administrative friction without compromising control.

5. Create and monitor departmental budgets

Assign a budget to each department using Pleo’s Budgets feature.

Create a dedicated tag for each department and link it to a quarterly or annual budget allocation. Both finance and department heads can then monitor spending in real time.

Automatic alerts notify stakeholders when spend reaches key thresholds, such as:

• 75% of budget used
• 100% of budget reached
• Budget exceeded

This allows teams to adjust their spending before small overruns become larger problems.

6. Provide real-time oversight with analytics

Visibility is what turns budget ownership into true financial accountability.

With access to Pleo’s analytics dashboard, department heads can see exactly where their budgets are being spent – whether on software, travel, events or other operational costs.

This insight helps them:

• Spot spending trends
• Identify opportunities to optimise costs
• Make stronger cases for future budget requests

Finance maintains complete oversight, whilst managers gain the tools they need to lead more effectively.

Pro tip: Empowerment works best when it’s paired with the right level of governance. For an added layer of control, use Sequential Review. This allows department heads to approve expenses first, after which finance can perform a final audit before export or reimbursement.

This creates a double-check system that balances speed with accountability – and trust with control.

Turn budget holders into budget owners with Pleo

Custom budget limits do more than control spend. They change how organisations think about financial responsibility.

When department heads have clear limits, real-time data and the authority to act, they become active stewards of their budgets rather than passive recipients of finance policies.

That means:

• Faster purchasing decisions
• Better budget discipline
• Stronger accountability across the business
• Less administrative burden on finance

In other words, finance can move from policing spend to enabling smarter spending.

And that’s where real scalability begins.
