Multi-Currency Corporate Treasury for UK & EU Founders

Opening a corporate bank account used to be a two-week in-person process at a high-street bank. For early-stage startups, the combination of fintech banking platforms — principally Revolut Business and Wise Business — has made same-day multi-currency account setup a reality. This guide covers how to architect your corporate treasury stack for a UK or EU-incorporated entity, covering account structure, dual authorization controls, FX hedging, and the operational workflows that prevent costly mistakes.

Why You Need Multi-Currency Accounts

Most UK-incorporated startups with EU customers or EU-incorporated operating subsidiaries will transact in both GBP and EUR. Maintaining a single-currency account and converting on receipt or payment creates accumulated FX losses that can represent 1–3% of revenue annually at mid-market rates, and up to 5% at bank rates. With a multi-currency account, you hold GBP and EUR balances separately and convert only when operationally necessary, at interbank rates with minimal spread.

Revolut Business: Account Structure

Revolut Business allows you to create virtual sub-accounts in up to 28 currencies. For a UK/EU founder, the essential setup is: (1) a GBP current account for UK operating expenses, payroll, and HMRC tax payments; (2) a EUR current account for EU vendor payments and customer receipts; (3) a USD account if you operate with US vendors or receive USD revenue; (4) project or expense category sub-accounts for marketing budget, payroll reserves, and tax provisions. Use the "Pockets" feature to ring-fence funds for VAT, corporation tax, and payroll.

Dual Authorization Controls

For any payment above a material threshold (suggested: £5,000 single payment or £20,000 per week), implement dual authorization — a second signatory must approve the payment before it executes. Revolut Business supports team roles with approval workflows; Wise Business supports multi-user access with payment approval limits. For early-stage companies, dual authorization between two co-founders prevents unauthorized payments and significantly reduces the risk of business email compromise (BEC) fraud, which costs UK SMEs over £40 million annually.

• Set payment approval thresholds appropriate to your operating scale
• Assign "Admin" role only to founders; use "Employee" or "Viewer" roles for team members
• Enable 2FA (hardware key preferred) on all banking platform accounts
• Use virtual cards for recurring SaaS subscriptions — easy to cancel without disrupting the main account
• Review pending approvals daily; never leave large outgoing transfers pending overnight
• Maintain a secondary Wise account as a backup if Revolut is unavailable

Wise Business: The Complementary Layer

Wise Business excels at international wires to jurisdictions outside the Revolut network, particularly for payments to Eastern European contractors, South Asian development teams, and African markets. The multi-currency account comes with local bank details in GBP, EUR, USD, AUD, and CAD, allowing you to receive payments as if you had a local account in each currency. For payroll-as-a-service, Wise batch payments can process hundreds of contractor payments in a single upload.

Tax Provisioning Through Sub-Accounts

One of the most practical uses of multi-currency sub-accounts is systematic tax provisioning. Create a dedicated pocket or sub-account labeled "Tax Reserve" and transfer 20–25% of every invoice received into it immediately. For VAT-registered businesses, transfer the VAT-equivalent amount into a separate "VAT Reserve" pocket on receipt. By the time your quarterly VAT return or annual corporation tax bill arrives, the funds are already ring-fenced and earning interest (if your account tier includes interest), rather than having been consumed by operational spending.
