Quick guide: how to simplify expense claim approvals

Quick guide: How to simplify expense claim approvals in summary:

Expense approvals become slow and risky when processes rely on spreadsheets, email chains, and disconnected systems. To simplify expense approvals, organisations should embed policy rules at the point of entry, automate approval workflows, enable mobile receipt capture with OCR, and integrate expense data with HR and payroll systems.

By digitising and automating the process, HR and finance teams can reduce errors, improve VAT tracking, increase spend visibility, and speed up reimbursements — while maintaining stronger financial control. Integrated expense management software helps mid-sized UK organisations streamline governance, reduce admin time, and deliver a better employee experience.

Expense approvals shouldn’t feel like detective work.

Yet, for many HR and finance teams, that’s exactly what they become: chasing missing receipts, checking policy compliance manually, emailing managers for sign-off, and reconciling sprawling spreadsheets at month end… uugghhgh… it’s boring, time-consuming, frustrating, and risky – particularly in growing organisations where spend is increasing and governance matters more than ever.

If you’re supporting a growing workforce, simplifying expense approvals isn’t just about speed. It’s about accuracy, improving the employee experience, protecting budgets, and giving leadership real visibility over spend. You know… the kind of stuff that quietly becomes critical as organisations scale.

Why expense claim approvals can become so complicated

Now, you might be reading this thinking expense claim approvals should and can be easy. An employee submits a claim. A manager approves it. Finance reimburses the cost. Job done. How hard can it be?!

In practice, however, complexity creeps in very quickly. Especially when:

• Claims are submitted by email, spreadsheet, or paper.
• Receipts are missing or unclear.
• Managers approve without checking policy.
• VAT isn’t recorded correctly.
• Finance only sees total spend after reimbursement.

Like any finance-related operation, the devil really is in the detail. Small gaps or inconsistencies create bigger (and more serious) problems. A missing receipt here, an unchecked policy breach there… and suddenly approvals stall, reporting becomes unreliable, and finance teams are left untangling issues that could have been avoided.

HMRC is clear about the importance of maintaining accurate expense records and evidence for tax purposes, including VAT reclaims (see HMRC guidance on expenses and benefits). When processes are manual or inconsistent, compliance risks rise exponentially, and so does administrative effort.

The result? Delays, frustrated employees waiting for reimbursement, and finance teams spending hours correcting avoidable errors.

So, if you want to avoid all that nonsense and ensure your expense processes are rock solid, here’s how to make it happen.

1. Start with clear, built-in expense policies

Many organisations already have an expense policy. The problem is that it’ll most likely live in an obscure PDF on the company intranet, buried in an old new starter manual or – worst of all – sitting printed in someone’s desk drawer. Everywhere but inside the approval process itself!

If employees can submit out-of-policy claims without warning, managers are forced to become policy interpreters. That slows everything down and increases inconsistency.

A better approach is to embed policy rules directly into your expense system:

• Define spending limits by role or department.
• Set automated flags for out-of-policy claims.
• Require mandatory fields for VAT or mileage.
• Trigger alerts before submission, not after approval.

When policy is enforced at the point of entry, most errors disappear before they reach a manager’s inbox. That reduces approval time dramatically and strengthens governance at the same time.

2. Make it easy for employees to submit claims properly

If you want faster expense claim approvals, start by making life easier for employees. Clunky or legacy systems lead to rushed submissions. Rushed submissions lead to missing receipts, incorrect coding, and vague descriptions. And that creates bottlenecks further down the line.

Modern expense management tools allow employees to:

• Capture receipts via mobile using OCR (optical character recognition).
• Submit claims in minutes from desktop or phone.
• Automatically calculate mileage using point-to-point mapping.
• Match corporate card transactions with receipts.

Digital expense processes can save up to three hours per claim and reduce errors by 43%. That’s a significant efficiency gain – particularly in organisations with high volumes of claims. The key principle is simple: if submission is quick and intuitive, approvals become quicker too.

3. Automate approval workflows

Manual approval chains are one of the biggest causes of delay. If managers are emailed individually, or if finance has to check who should approve what, claims sit idle. And when someone is on holiday? Well, more often than not, everything stops.

Automated workflows solve this by:

• Routing claims to the correct approver based on organisational structure.
• Applying different workflows by department or value threshold.
• Escalating overdue approvals automatically.
• Providing visibility over approval timelines.

Take our own integrated expense management software module, for example. It’s designed to sit within the wider HR ecosystem and operate seamlessly within the Cezanne HR software suite, meaning employee data, cost centres, and organisational structures sync automatically. That removes the need to manually maintain approver lists or rekey information across systems.

It also reduces reliance on disconnected tools and spreadsheets – things that often create more cost and complexity than they solve.

4. Improve visibility before month-end

One of the biggest frustrations for finance leaders is discovering spend too late. Without real-time dashboards, expense data only becomes visible once claims are processed and exported. By then, overspend may already have occurred.

Interactive reporting changes that dynamic:

• Live dashboards showing spend by department or cost centre.
• Identification of frequent out-of-policy claims.
• Tracking time-to-approval.
• Forecasting upcoming reimbursement runs.

This level of visibility doesn’t just speed up approvals; it strengthens financial control. It also supports better decision-making, especially for Finance Directors who need confidence in forecasting and cash flow. For context, the Office for National Statistics (ONS) regularly highlights how cost pressures continue to affect UK businesses. In that environment, clear spend visibility isn’t a ‘nice to have’. It’s essential.

5. Connect expenses with payroll and HR

Disconnected systems create unnecessary admin. If expense claim approval data needs to be exported, reformatted, and manually uploaded into payroll, errors will creep in. Finance teams end-up double-keying information. Ultimately, a disjointed system can delay reimbursements, leaving employees temporarily out of pocket – something few organisations want to risk in the current economic climate.

An integrated HR and expense workflow removes that friction. Data flows seamlessly between:

• Employee records
• Cost centres
• Payroll exports
• Reporting dashboards

Cezanne’s approach brings expense management into the same ecosystem as Core HR, reducing the need for multiple vendors and creating a single source of truth. For organisations already modernising payroll processes, this can be a logical next step. (You might also find our research into payroll accuracy useful here, as both areas rely heavily on strong data governance.)

6. Don’t underestimate employee experience

Finally, and as highlighted earlier, remember that expense approvals aren’t just a finance process – they’re part of the employee experience. Delayed reimbursements create frustration and even financial hardship. Opaque processes erode trust and engagement, whilst inconsistent approvals feel unfair.

By contrast, a streamlined system:

• Gives employees clarity on what’s allowed.
• Speeds up reimbursement.
• Reduces back-and-forth queries.
• Creates transparency around approval status.

For HR leaders focused on employee engagement and retention, this really matters. It reinforces a culture of fairness and efficiency, and removes an avoidable source of irritation. So, if you’re working on broader initiatives to improve employee experience, simplifying admin-heavy processes like expenses is often low-hanging fruit.

Bringing it all together

Simplifying expense approvals isn’t about removing control. It’s about embedding control in the right place.

When policies are built into the system, workflows are automated, submissions are easy, and data is connected across HR and payroll, approvals become faster by default. Finance gains visibility. HR reduces admin. Employees get reimbursed quickly and fairly. And perhaps most importantly, your team gets hours back every week to focus on work that actually moves the business forward.
