What is an expense claim and how is it different from an expense report?

An expense claim is an employee's formal request to be reimbursed for work-related costs paid personally. The term is most common in the UK and Commonwealth countries; U.S. companies typically say expense report. The underlying process is identical: document the cost, attach receipts, get manager approval, and receive repayment.

How long does it take to get an expense claim reimbursed?

Reimbursement timelines range from a few days to several weeks depending on the process. Manual workflows typically run two to six weeks from submission to payment. Navan Expense shortens that cycle through automated approval routing and real-time submission prompts. Forrester's Total Economic Impact study found Navan reduces expense management time by 40% compared to manual processes [2].

What documents are required to submit an expense claim?

Most T&E policies require the date, vendor, amount, expense category, a business purpose statement, and a receipt for each claim line. Receipts captured at the point of purchase are rarely lost or disputed. Navan Expense captures receipts via mobile camera and uses AI to extract the vendor, date, amount, and suggested category automatically, so employees confirm details rather than type them from scratch.

Why do expense claims get rejected?

The most common reasons for a claim being rejected are missing receipts, vague business purposes, late submission, and policy violations such as exceeding meal limits. GBTA research found that 46% of employees avoid submitting small expenses because the process is too difficult [3]. Navan addresses the root cause by capturing receipts and prompting for business purpose immediately after each transaction, preventing common errors before submission.

What is the difference between an expense claim and a per diem allowance?

An expense claim reimburses actual costs the employee paid personally, supported by receipts. A per diem is a fixed daily allowance covering anticipated costs without requiring individual receipts.

Can employees submit expense claims for international business travel?

International claims follow the same documentation requirements as domestic ones but add considerations: currency conversion, country-specific tax treatment, and potentially different per diem rates by destination. Employees submit the same way regardless of where the expense occurred.

Expense Claim

An expense claim is a formal request an employee submits to recover approved work-related costs paid from personal funds. The submission includes the expense amount, date, category, vendor, and business purpose, supported by receipts, and routes through manager and finance review before reimbursement is issued. The term is standard in the UK and Commonwealth countries; in the U.S., the same submission is typically called an expense report.

Key Takeaways

An expense claim is a formal request an employee submits to recover work-related costs paid from personal funds. Finance teams review these submissions to confirm business purpose, check policy compliance, and approve reimbursement. Navan automates the entire claim workflow, cutting the time employees spend per expense by 80% [2].

Expense claims are the UK equivalent of what U.S. companies call an expense report: both describe the employee's submission to recover approved business costs.
71% of travel and finance professionals spend more than 30 minutes per expense claim, per the Skift and Navan 2026 State of Corporate Travel and Expense survey [1].
58% of employees across Europe report that delayed reimbursements affect their personal finances, per GBTA research [3].
Navan Expense captures receipt data at the point of purchase, pre-fills claim fields automatically, and routes submissions through approval without manual entry.

What is an Expense Claim?

An expense claim is a formal request an employee submits to recover work-related costs paid from personal funds. Unlike a corporate card charge, which flows into an expense system automatically, a claim requires the employee to actively document and submit the cost for review.

The term "expense claim" is standard in the UK and Commonwealth countries. In the U.S., the same process is typically called an expense report, though the mechanics are nearly identical: document the cost, attach the receipt, gain manager approval, and receive reimbursement. Any out-of-pocket expense an employee incurs for a legitimate business purpose is a candidate for a claim.

How does an expense claim work?

The claim process follows five consistent steps, though the time each step takes varies widely between manual and automated environments.

Incur and document. The employee pays personally and keeps the receipt. Mobile capture tools can photograph receipts on the spot; without them, documentation frequently arrives incomplete or missing by the time the claim is filed.
Submit. The employee enters the date, amount, vendor, expense category, and a business purpose statement. Most travel and expense (T&E) policies require submission within 30 to 90 days of the expense date.
Manager review. The direct manager confirms each line item complies with company policy. Out-of-policy amounts require a written justification.
Finance processing. The finance team verifies approved claims, codes them to the correct budget category, and schedules payment. In manual environments, this step generates the longest delays.
Reimbursement. The employee receives payment through payroll, direct deposit, or, in some organizations, a check. Timelines range from a few days to several weeks depending on the process.

What qualifies as an expense claim?

Most T&E policies recognize six standard categories:

Travel: Airfare, train tickets, taxi and rideshare fares, mileage driven in a personal vehicle, and parking.
Accommodation: Hotel stays required when business travel involves an overnight absence from the employee's normal work location.
Meals: Business meals with clients or colleagues, and daily food costs during multi-day travel governed by per diem rates.
Client entertainment: Meals and events tied directly to business purposes, often subject to a separate, higher spending threshold.
Communication: Phone and internet charges incurred while traveling for business.
Professional subscriptions and training: Fees directly necessary for performing the employee's role.

Expenses that lack a clear business purpose, exceed policy limits without prior approval, or arrive without documentation are typically rejected.

Why expense claims get delayed or rejected

Delay and rejection stem from the same root causes across most organizations. The four most common are:

Missing receipts: Without documentation, finance cannot process a claim even when the expense is legitimate.
Late submission: Many T&E policies include filing deadlines. Claims submitted after 60 or 90 days may require special approval or get declined automatically.
Policy violations: Exceeding meal limits, booking outside preferred vendors, or including personal costs alongside business ones.
Vague business purpose: "Client meeting" rarely gives an approver enough context. "Client dinner, Q2 contract review, Chicago, May 14" provides what's needed without follow-up.

Finance teams that configure their expense systems to require a minimum business purpose length (50 or more characters) before submission see fewer rejection cycles, because the field constraint forces specificity before the claim ever reaches a reviewer. Navan Expense applies this approach by prompting employees to add context immediately after each card transaction, when the business purpose is still fresh.

On the employee side, the cost of a slow claim process extends beyond inconvenience. GBTA found that 46% of employees avoid submitting smaller expense claims entirely because the process feels too difficult [3], which means organizations routinely undercount actual business spending and lose visibility into real travel and expense costs.

How Navan automates the expense claim workflow

Automated expense platforms replace the manual documentation cycle with a workflow that begins at the point of purchase. When employees use a Navan corporate card, the platform captures the merchant name, amount, and date automatically. The employee adds a business purpose and receipt photo, and the claim routes to the approver without additional manual steps.

The operational difference is measurable. Forrester's Total Economic Impact study found that expense management time drops by 40% and finance teams save 24 minutes per report compared to manual workflows [2]. For organizations processing hundreds of claims monthly, that represents hundreds of hours returned to higher-value work each year.

Manual claim processes create predictable backlogs because they require employees to reconstruct context days or weeks after the expense occurred. The receipt is lost, the business purpose is vague, and the approver sends the claim back for clarification. The fix is structural: capture data at the transaction, not at month-end.

How do expense claims compare to corporate card reconciliation?

Expense claims and corporate card reconciliation address the same underlying need from different starting points.

An expense claim begins with personal payment. The employee must actively document and submit the cost to initiate reimbursement. Corporate card reconciliation starts from a charge already captured by the card issuer. The employee categorizes and annotates existing transaction data rather than constructing a new record from a receipt.

In practice, most organizations handle both. A typical business trip generates a mix of card purchases and out-of-pocket costs the employee couldn't or didn't put on a company card. A unified expense platform handles both in a single workflow, giving finance teams one consolidated view of all business spending rather than two separate reconciliation tracks to manage at month-end.

Expense claim best practices

Three practices consistently reduce cycle time and rejection rates across organizations.

Submit within 24 hours. Claims filed the day the expense occurs have more accurate business purposes, complete receipts, and faster approval rates. Waiting until week's end or month-end means reconstructing context that has already faded and creates concentrated approval backlogs when finance teams have the least capacity.

Know your policy before you spend. Finance teams that publish clear category limits, meal per diem allowances, and entertainment thresholds before trips start see fewer out-of-policy submissions at the claim stage. An employee who knows their daily meal allowance before leaving makes compliant spending decisions at the restaurant. Learn how expense report automation supports policy enforcement at the point of purchase.

Categorize accurately on submission. A flight filed under "Meals" or a client dinner coded to "Office Supplies" requires manual correction during month-end close, cascading into delays across the entire reconciliation cycle. Configuring default categories by vendor type removes most classification errors before they reach the finance queue.

Mileage reimbursement: A specific type of expense claim covering distance driven in a personal vehicle for business purposes, calculated against a government-set rate per mile or kilometer.
Expense allocation: The process of assigning each approved claim to the correct budget code or cost center in the general ledger, ensuring spending is visible against the right owner.
Corporate card: A company-issued payment card that eliminates personal fund outlays for most T&E purchases, replacing the expense claim cycle with direct card reconciliation.
