What Is an Expense Management Workflow? (And How to Improve It)

An employee buys supplies for the office. Another submits a mileage claim. A manager approves a hotel booking, but the receipt is missing. Meanwhile, finance is trying to work out which expenses are ready for accounting and which still need attention.

None of these purchases is particularly complicated. It is everything that happens between spending the money and recording it correctly that creates the work.

An expense management workflow is the process a business uses to capture, check, approve, record and, where necessary, reimburse employee expenses. It defines who is responsible for each stage, what information is required and how expenses move from purchase to accounting.

When that process works, employees know what they can spend, managers have the information they need to approve claims, and finance receives complete records without having to chase them.

When it doesn't, the problems tend to surface at month-end.

An expense workflow is only as effective as the information moving between its stages. If employees submit incomplete claims, approvals slow down. If managers delay approvals, finance cannot finalise the expense records. If coding and supporting documents are missing at the accounting stage, the entire process becomes more difficult.

What looks like an approval or reconciliation problem may actually have started much earlier.

This guide explains the stages of an expense management workflow, where common bottlenecks occur and how finance teams can improve the process without adding unnecessary administration.

The six stages of an expense management workflow

Every business has slightly different requirements, but most expense management processes follow the same six stages.

1. Set spending rules before the purchase

A good workflow begins before anyone spends money.

Employees need to know which expenses are permitted, whether they need approval before making a purchase, what limits apply and which payment methods they should use.

For example, a business might allow employees to purchase routine office supplies within an agreed budget but require prior authorisation for higher-value equipment.

These requirements should be documented in a clear company expense policy and made accessible to employees.

Control spending before and after the purchase:

There is an important difference between controlling how money is spent and checking whether an expense meets company policy.

Company card controls can restrict spending before a transaction takes place. For example, finance may set a daily spending allowance or restrict certain types of card transactions.

Expense policies govern how spending is recorded and reviewed. They can require employees to attach receipts, provide a business purpose or explain an exception before submitting a claim.

Both play a role in preventing errors, but they operate at different points in the process.

A business using employee expense cards alongside expense policy software can apply controls to both the purchase and the subsequent expense submission.

2. Capture the expense and supporting information

Once a purchase has been made, the employee needs to record it.

This should include the transaction amount, merchant, date, business purpose and relevant receipt or invoice. Depending on the expense, finance may also need a cost centre, project reference or additional tax information.

The sooner this information is captured, the less likely it is that employees will forget details or lose receipts.

A mobile expense management app makes this easier by allowing employees to submit expenses and photograph receipts without waiting until they return to the office.

Where company cards are connected to the expense management platform, transaction information can also be captured automatically, reducing the need for manual entry.

3. Check the expense against company policy

Before an expense reaches an approver, the submission should be checked against the company's requirements.

Is the receipt attached? Has the employee provided a business purpose? Is the expense assigned to the correct category? Does it fall within the permitted spending limits?

These checks should not depend entirely on finance reviewing every submission manually.

Expense policy software can apply rules at the submission stage, requiring employees to provide information or flagging exceptions for review.

Expend, for example, allows businesses to set expense submission requirements at company, team or individual level. Missing information can trigger a warning or prevent submission, depending on the rule.

The advantage is straightforward: approvers receive more complete claims, and employees can correct simple mistakes while the purchase is still fresh in their minds.

4. Route the expense for approval

The next stage is deciding whether the expense should be approved, rejected or returned for further information.

Not every purchase requires the same level of scrutiny.

A £12 coffee purchased during an approved business trip should not necessarily follow the same approval process as a £1,200 client dinner.

If both expenses require identical manual review, managers spend time processing routine transactions instead of focusing on purchases that need closer scrutiny.

An effective expense approval workflow should distinguish between routine spending and genuine exceptions.

For example, a business might automatically approve low-value expenses that meet its policy requirements while routing higher-value purchases to a department manager. This reduces unnecessary review without removing oversight from transactions that require it.

5. Reimburse employees where required

If an employee has paid for a business purchase personally, the approved claim needs to move into the reimbursement process.

Finance should know who needs to be paid, how much is owed and whether the payment has been completed.

Delays often occur when approved claims remain in a separate spreadsheet or payment queue, leaving employees uncertain about when they will receive their money.

A connected reimbursement process reduces the need to transfer information between systems and helps finance keep track of outstanding claims.

Businesses can also reduce reliance on personal employee spending by using company expense cards for regular, predictable purchases.

6. Record and reconcile the expense

The final stage is transferring the completed expense record into the company's accounting process.

Finance needs the correct category, supporting documentation, tax information and transaction details to reconcile the expense accurately.

Where possible, these details should be checked before export rather than corrected after they reach the accounting system.

Accounting automation helps businesses connect approved expense data with software such as Xero and QuickBooks, reducing repetitive entry and making reconciliation easier.

At this point, the expense workflow is complete: the purchase has been recorded, checked, approved where necessary, reimbursed if applicable, and accounted for.

Where expense management workflows go wrong

The biggest problems often occur between stages rather than within them.

An employee submits a claim without a receipt, so the manager cannot approve it. A manager approves an expense, but finance discovers that the accounting category is wrong. An employee expects reimbursement, but their approved claim has not reached the payment process.

Each problem creates another handoff, another email or another task for finance.

A particularly common mistake is treating expense submission and approval as separate activities. When the submission process does not require the information an approver needs, the business builds delays into its workflow.

The same applies to accounting. If employees and managers do not capture the relevant details before an expense reaches finance, the work simply moves downstream.

The solution is to look at the entire process rather than trying to make one stage faster in isolation.

How to improve your expense management workflow

Improving a workflow does not have to mean introducing more rules or additional approval stages.

Start with the steps that create the most unnecessary work.

✅ Remove avoidable manual checks

Review which expenses genuinely need individual approval.

If finance is manually reviewing every low-value, policy-compliant transaction, consider whether some could be approved automatically under clearly defined conditions.

Keep manual review for exceptions, unusual purchases and transactions requiring additional oversight.

✅ Make the submission process easier

Employees are more likely to submit complete claims when the process is straightforward.

Make receipt capture available on mobile, use clear expense categories and avoid asking for information that is not relevant to the purchase.

Where information is mandatory, explain what is required before the claim can be submitted.

✅ Give each expense a clear owner

An expense should not sit unresolved because nobody knows who needs to review it.

Define approval responsibilities by team, department or expense type. Include arrangements for absence and escalation so claims do not remain in a manager's queue indefinitely.

✅ Connect the stages

Look for opportunities to remove manual transfers between submission, approval, reimbursement and accounting.

If an approved expense still needs to be copied into another spreadsheet before it can be reimbursed or recorded, there is probably an opportunity to simplify the process.

✅ Review exceptions rather than every routine transaction

Finance teams should be able to see which expenses are missing information, awaiting approval or outside policy.

That makes it easier to concentrate on the transactions requiring attention instead of repeatedly checking completed claims.

✅ Make the process work for everyone involved

A well-designed workflow should make life easier for employees, approvers and finance teams.

Employees know what they can spend and can submit expenses without unnecessary paperwork. Managers receive complete claims and only need to review transactions requiring their attention. Finance has visibility over outstanding expenses, can identify exceptions quickly and receives better-quality records for accounting.

The aim is not to create more rules. It is to make the existing process easier to follow and less dependent on manual intervention.

Actionable insight: find the bottleneck in your current workflow

Take a sample of 20 recently submitted expenses and follow each one from purchase to accounting.

Record where additional work was required. Did employees need chasing for receipts? Were claims returned because information was missing? Did approvals take longer than expected? Did finance need to correct the coding before reconciliation?

Look for recurring problems rather than isolated mistakes.

If most delays occur before approval, improve the submission process. If expenses repeatedly sit with managers, review the approval rules and responsibilities. If corrections happen after approval, focus on coding and accounting requirements earlier in the workflow.

This gives finance a practical starting point for improving the process without changing everything at once.

Final thoughts

A good expense management workflow makes business spending easier to manage without creating unnecessary work for employees, managers or finance.

The aim is to capture the right information, apply the right controls and move each expense through the process with as little manual intervention as possible.

When submission, policies, approvals and accounting work together, finance spends less time resolving avoidable problems and more time managing the business's spending.
