Why this matters for an overseas-owned UK company
If your customers are mainly outside the UK, invoicing and receiving in GBP forces them to convert and forces you to convert back, losing money twice on spread and fees. A multi-currency account lets you receive USD from a US customer and EUR from an EU customer as if you had local accounts there.
This is separate from the company's functional currency for accounting purposes: UK statutory accounts and corporation tax computations are normally prepared in sterling, so foreign currency receipts still need converting to GBP at the appropriate rate for your accounts even if you hold the balance in the original currency.
