5 Expense Reimbursement Best Practices for Growing Teams
When your business is small, expense management runs on goodwill and a shared spreadsheet. As you grow, that breaks down. Here is how to build a process that scales.
1. Write your expense policy before you need it
Most businesses only write an expense policy after their first problem — an unexpectedly large claim, a disagreement about what is reimbursable, or an HMRC query. By then, the damage is done.
A clear expense policy does three things:
- Tells employees what they can and cannot claim before they spend money
- Gives managers objective criteria for approving or rejecting claims
- Demonstrates to HMRC that expense claims are being managed systematically
You do not need a 30-page document. A one-page policy that covers categories, per-day limits, receipt requirements, and the approval process is enough for most businesses under 50 people.
2. Capture receipts at the point of purchase
The single biggest source of friction in expense management is chasing receipts after the fact. Employees lose them. Thermal paper fades. People go on holiday and forget what a charge was for.
The fix is simple: require employees to photograph receipts immediately after purchase and attach them to the claim on the same day. When this becomes a habit, your admin burden drops dramatically.
This is where a mobile expense app earns its keep. If capturing a receipt takes 30 seconds in a mobile app — versus emailing it to finance, filling in a form, and attaching a photo later — compliance goes up enormously.
3. Set clear approval thresholds
Not every expense needs to go to a director. Defining approval thresholds by amount saves time and signals trust to your team.
A typical structure for a 10–50 person business:
- Under £50 — line manager approval
- £50–£250 — department head approval
- Over £250 — Finance Manager or Director
The specific numbers should reflect your business. What matters is that the thresholds are written down and applied consistently. Inconsistent approval decisions are one of the fastest ways to damage trust between employees and management.
4. Reimburse on a fixed, predictable schedule
Employees who pay for business expenses out of pocket are effectively lending the company money. Slow reimbursement — especially on larger amounts — causes real financial stress.
Best practice is to run expense reimbursements on the same cycle as payroll, or more frequently if your volume warrants it. What matters is that employees know when to expect payment and can rely on it.
If you are using a bank transfer process, build in a buffer for bank processing times. If you are using a tool that can trigger reimbursements instantly via Stripe — like Claimio — you can approve and pay on the same day.
5. Connect expenses directly to your accounting software
Manual data entry between your expense management process and your accounting software is where errors happen. Amounts get transposed. Receipts get lost in the gap. VAT amounts get missed.
If you are using Xero, QuickBooks, or Sage, the right expense tool should export approved claims directly — not require someone to retype them. This is not just a time saving; it is an accuracy improvement.
When expense data flows automatically from claim approval to your ledger, you get a clean audit trail, accurate VAT records, and a real-time view of spend — without anyone doing manual bookkeeping.
