The smart way to manage global spend from the UK

Expanding into new markets is an exciting opportunity. It shouldn’t feel like a financial juggling act. But for many UK businesses, managing expenses across currencies, entities, and countries quickly becomes a barrier to scale. Finance teams find themselves buried in spreadsheets, working with disconnected tools, and trying to piece together what’s really going on across the company.

This guide is designed to help. Whether you're setting up overseas staff or scaling a multinational operation, it will show you how to modernise your global expense management, so you can expand with confidence. 

What is multi-currency expense management?

Multi-currency expense management is the ability to track, control, and reconcile business spending in multiple currencies across regions, teams, and suppliers, all from a single system.

For CFOs and finance teams, this means employees can spend in their local currency while the business maintains centralised oversight. You can issue cards, approve expenses, and pay suppliers in the currencies they use, without relying on separate platforms, bank accounts, or manual currency conversions.

Done well, multi-currency expense management helps you:

• Avoid unnecessary FX fees

• Improve visibility across international teams

• Speed up approvals and reimbursements

• Stay compliant with local regulations

• Make faster, more informed decisions with real-time data

As businesses expand globally, being able to do this becomes really important. Without it, expense processes become fragmented. Teams work across disconnected tools, finance spends time reconciling accounts manually, and you lose control over how and where money is being spent.

A modern platform with built-in multi-currency support brings everything into one place, helping growing companies scale without friction.

Why efficient global expense management matters

Managing expenses gets trickier as your business grows, especially when you’re operating across borders. Things start to feel messy: Approvals take longer, costs go up, and teams spend more time fixing problems than focusing on the work that matters. Left unchecked, these inefficiencies can slow you down, increase risk, and make it harder to make smart decisions quickly.

Some of the most common challenges include:

Hidden FX fees and poor exchange rates: Using multiple tools and traditional banks often means relying on high-margin exchange rates and incurring unnecessary fees.

Missed VAT reclaims and tax headaches: Without proper documentation or categorisation, opportunities for VAT recovery are often missed, complicating compliance.

Hours of manual reconciliation: Juggling disconnected platforms for card payments, reimbursements, and accounting leads to wasted time and reduced visibility.

Limited control over team-level spend: Without centralised approval workflows and real-time tracking, it's difficult to enforce policies or manage budgets proactively.

Delayed reimbursements: When finance teams are buried in manual processes, employees are left waiting, damaging morale and trust.

An efficient global expense management system helps you reverse these issues by enabling:

Automation of low-value tasks: AI-powered categorisation, receipt matching, and pre-set approvals free up time and reduce human error.

Improved cash flow and budget control: Real-time visibility into spend helps finance teams to make better decisions and respond to changes quickly.

Scalable expense policies: Flexible workflows and user permissions make it easy to be consistent with policy enforcement across teams, geographies, and entities.

Audit readiness and tax compliance: Centralised data storage, integrated accounting tools, and built-in reporting features help meet both HMRC and international regulatory requirements.

Benefits of a global expense management system for UK businesses

Whether you’re a startup scaling into the US or a multinational with teams across Europe, a consolidated expense management solution gives you:

1. End-to-end global spend visibility

Unifying global expenses in one system allows you to see and understand how money is spent across currencies, regions, and departments. With a single dashboard, finance teams can track budgets, enforce policies, and spot anomalies faster.

2. Reduced transaction and FX costs

By managing multi-currency expenses in one platform, businesses avoid unnecessary conversions and get transparent FX rates. This reduces fees and eliminates reliance on multiple intermediaries.

3. Faster, local-friendly payments and reimbursements

With the ability to issue payments using local methods and currencies, businesses can pay employees and suppliers more quickly and reliably, cutting down delays and avoiding SWIFT-related costs.

4. Built-in tax and audit support

Consolidated platforms make it easier to store documentation, categorise spending correctly, and meet the requirements of HMRC and international tax authorities. This is helpful for VAT recovery and audit readiness.

How to choose the best multi-currency expense management software

Look for more than just an expense tool. Ideally, you want a platform that simplifies global financial operations. The best platforms offer:

• Multi-currency accounts and wallets

• Real-time FX and global payment rails

• Company cards with approval workflows

• Receipt scanning and AI-powered categorisation

• Accounting integrations (e.g. Xero, NetSuite, QuickBooks)

• Customisable roles and permissions (e.g. admins, users)

There are some important questions to ask when choosing multi-currency expense management software, including:

• Can it consolidate expense data from all regions?

• Does it offer FX transparency and control?

• Will it scale across new teams and legal entities?

• Is it built on modern infrastructure, or just another layer on top?

What UK businesses need to know about tax and compliance when managing global expenses

HMRC and international tax authorities require clean audit trails for expenses, which means you need to be able to supply:

Digital copies of receipts and supplier invoices

Every transaction should have a clear, digital record that is easily accessible and linked to the right team or budget.

Proof of business purpose

Each expense should show why it was incurred: Whether it’s tied to a client, project, or event.

Reconciled, categorised transactions

Spend should be matched to accounts and clearly tagged (e.g. travel, software, meals) to support accurate reporting.

VAT documentation (where eligible)

To reclaim VAT, especially on cross-border spend, you need valid invoices and proper tracking of VAT-eligible transactions.

Airwallex helps UK businesses stay tax-ready with:

• Built-in documentation capture and storage

• Approval logs and role-based permissions

• Easy integrations with HMRC-approved accounting tools
