What an expense policy should cover (and why SMEs need one)
A clear expense policy helps small and medium-sized businesses control costs, reduce awkward conversations, and keep records consistent for budgeting and tax reporting. It also protects employees by setting expectations upfront—what’s allowed, what isn’t, and how to claim.
At minimum, a UK expense policy should cover:
- Scope and eligibility: who can claim (employees, directors, contractors) and which situations count as business expenses.
- Approved expense categories: e.g. travel, accommodation, meals, client entertainment, mileage, home-working items, subscriptions—plus clear exclusions (fines, personal purchases, alcohol rules, etc.).
- Spending limits and approvals: per-item caps, daily allowances, and when pre-approval is required (e.g. hotels over a set rate, flights, conferences).
- Receipts and evidence: what proof is needed, acceptable formats (photo/scanned), and what to do if a receipt is missing.
- Claim process and deadlines: how to submit (app, spreadsheet, portal), cut-off dates, and expected reimbursement timescales.
- Mileage and travel rules: when to use public transport vs car, parking/tolls, and how mileage is recorded.
- VAT and tax record-keeping: what information must be captured on receipts/invoices to support your records.
- Non-compliance and exceptions: how exceptions are approved and what happens if claims breach the policy.
For SMEs, these basics prevent “policy drift” as the team grows, reduce time spent chasing receipts, and make cashflow more predictable by standardising when and how reimbursements happen.
UK expense policy template (copy-and-paste sections)
Purpose: This policy explains what business expenses we reimburse, how to claim them, and the checks we use to keep records consistent.
Who it applies to: All employees and contractors claiming expenses on behalf of [Company name] in the UK.
What we reimburse (examples): Pre-approved travel, client meetings, work-related supplies, and necessary home/remote-working costs where agreed. Not reimbursed: personal purchases, fines/penalties, alcohol without a business purpose, upgrades for comfort, or expenses without evidence (unless approved as an exception).
Spending rules: Use the most cost-effective option that meets the business need. Get approval from [Role/Manager] before any single item over £[amount] or any overnight stay. Use company accounts where available; otherwise, claim reimbursement.
Receipts & evidence: Provide an itemised receipt/invoice showing supplier, date, amount, and VAT (if applicable). For mileage, include date, journey start/end, purpose, and miles. Store evidence in [system].
How to submit a claim: Submit via [tool] within [X] days of the expense. Add a clear description and cost centre/project code. Claims are reviewed by [approver] and processed in the next payroll/payment run.
Rates & limits: Mileage: [rate] per mile. Meals: up to £[amount] per day when travelling. Accommodation: up to £[amount] per night (or “reasonable”).
Exceptions & audits: Exceptions require written approval. We may audit claims; inaccurate or misleading claims may lead to repayment and internal action.
Policy owner & review: Owned by [Finance/HR]. Reviewed every [12] months or after major changes.
How to implement the policy: approvals, receipts, and month-end close
Set up a simple workflow that matches how your team already spends money. Start by defining who can approve what: for example, line managers approve day-to-day claims, budget holders approve project spend, and a director approves anything above a set threshold. Build this into your expense tool (or a shared form) with required fields: date, supplier, business purpose, cost centre, VAT amount (if applicable), and payment method.
For receipts, make submission rules unambiguous. Require a receipt or invoice for every claim where possible, with a clear exception process (e.g., lost receipt declaration approved by a manager). Ask employees to upload images at the time of purchase, not at month-end, and to include itemised receipts for meals and hospitality. If you reclaim VAT, specify that VAT receipts must show the supplier’s VAT number and the VAT breakdown; otherwise, the claim can still be reimbursed but coded as non-reclaimable VAT.
For month-end close, publish a fixed timetable: submission deadline (e.g., the 2nd working day), manager approval deadline (e.g., the 4th), and finance review/payment date. Finance should run checks for duplicates, policy breaches, missing business purpose, and unusual patterns, then code expenses to the general ledger and reconcile corporate cards. Keep an audit trail of approvals and attachments, and store records securely for your retention period. Use a short monthly report to flag recurring issues and update training or policy wording accordingly.
How to set up expenses in Xero or QuickBooks (categories, VAT, tracking)
Set up expenses so staff can code claims consistently and you can report by department, project, and VAT type. Start by aligning your software with your expense policy categories (for example: travel, accommodation, subsistence, mileage, client entertainment, homeworking, and training). In Xero, review Chart of Accounts and add or rename expense accounts; in QuickBooks, update Chart of Accounts and create matching Expense or Cost of Sales categories. Keep the list short and mutually exclusive to reduce miscoding.
VAT setup: confirm your VAT scheme (Standard, Flat Rate, Cash Accounting) in the tax settings before staff start submitting receipts. Create clear rules for common scenarios: UK VAT receipts (standard-rated), zero-rated items, non-VATable expenses (e.g., most rail tickets), and overseas costs (usually no UK VAT to reclaim). Encourage attaching VAT receipts and capturing the supplier VAT number where shown. If you use mileage rates, treat these as non-VATable unless you have fuel VAT receipts and a process to reclaim it.
Tracking: enable tracking categories/tags for department, cost centre, and project/client. In Xero, use Tracking Categories; in QuickBooks, use Classes and Locations. Make one tracking field mandatory (e.g., department) and keep optional fields for edge cases. Finally, set up approval workflows and spend limits (e.g., manager approval over a threshold) and require receipt attachment for every claim to support audits and consistent reporting.
Corporate cards vs employee reimbursements vs prepaid cards: what to use when
Corporate cards suit predictable, recurring business spend where you want real-time visibility and fewer out-of-pocket claims. Use them for travel, software subscriptions, client meetings, and regular supplier purchases. They work best when you can set merchant/category limits, require receipt capture, and enforce pre-approval for higher-value items. They’re less suitable for one-off contractors or roles with minimal spend, and you’ll want clear rules on personal use, card sharing, and what happens when a receipt is missing.
Employee reimbursements are best for occasional, low-frequency expenses or situations where a card can’t be used (e.g., small cash-only purchases, mileage, or ad-hoc local travel). They’re also useful during onboarding before a card is issued. Reimbursements need tight controls to avoid admin drag: set claim deadlines, require itemised receipts, define rate rules (e.g., mileage rates you adopt internally), and specify approval steps. They’re not ideal for frequent travellers or teams with heavy spend because they increase processing time and can frustrate staff who regularly front costs.
Prepaid cards fit controlled, capped budgets and temporary access—think interns, project teams, events, or site work where you want to ring-fence spend. They’re useful when you want to load a fixed amount, restrict where it can be spent, and avoid credit exposure. They can be less convenient for deposits (e.g., hotels/car hire) and may require more top-ups if budgets shift. Pair them with receipt rules and a simple process for returning cards or reconciling unused balances.
Common UK expense policy questions (receipts, mileage, subsistence, WFH, gifts)
Do I always need a receipt?
Most policies require itemised receipts for any claim, especially travel, accommodation and client entertainment. If a receipt is missing, many employers ask for a short written explanation and may cap the amount or refuse the claim. Digital receipts and card statements are often accepted if they clearly show supplier, date and amount.
How does mileage reimbursement work in the UK?
Policies usually distinguish between company cars and personal vehicles. For personal cars, many employers align with HMRC’s Approved Mileage Allowance Payments (AMAP) rates and require a mileage log (start/end location, purpose, miles). Commuting to a normal workplace is typically not claimable; business travel between sites usually is.
What counts as subsistence?
Subsistence generally covers reasonable meals and non-alcoholic drinks when you’re travelling for work and can’t reasonably return home. Policies often set daily caps, require receipts, and exclude mini-bar items or meals that are “normal” when working at your usual location.
Can I claim working-from-home (WFH) expenses?
Many templates allow either a fixed allowance (where applicable) or specific, evidenced costs that are wholly for work (for example, necessary equipment approved in advance). Ongoing household bills are commonly restricted unless your employer explicitly agrees a method.
Are gifts and entertainment allowed?
Often yes, but with tight controls: pre-approval, modest limits, clear business purpose, and a record of attendees/recipient. Cash gifts are commonly prohibited, and anything that could look like an inducement is usually disallowed.
