Multi-currency account Wise vs Mercury: African SME + diaspora 2026

A modern African SME (export e-commerce, SaaS, freelance agency) receives in EUR/USD/GBP. Local bank accounts: expensive XOF conversions (5-8% spread). Multi-currency accounts like Wise / Mercury: 0.5-1% conversion, UK/EU/US IBAN, easy international scaling.

TL;DR

- Wise Business: multi-currency (50+ currencies), 0.4-0.6% conversions, UK + EU IBAN.

- Mercury: USD-only, free, perfect for US-incorporated startups (Atlas).

- For African SME: Wise > Mercury generally.

Common pitfalls

• Convert everything immediately — unnecessary FX loss. Keep original currency if upcoming payments.
• Wise account for illegal / undeclared VAT transactions — Wise audits + suspends.
• No reconciliation — multi-currency + multi-account = complex accounting. Dolibarr / Odoo ERP essential.
• Wise cash limit — Wise dislikes large cash transactions or gray industries (crypto, gambling, weed).
• International VAT / tax — a Wise EU account doesn't exempt SN VAT on local sales.
