Business account for an IT contractor on B2B — multi-currency, cheap transfers
Developers working on B2B contracts in Poland have different needs from a typical sole proprietorship. If you invoice clients abroad — often in euros or dollars — three things become key: a multi-currency account, a low currency-conversion cost and cheap international transfers. A standard "free business account" can turn out expensive once you add the FX spread and SWIFT fees.
Why an IT contractor on B2B needs a different account
A typical B2B developer receives payments from a foreign client while paying costs mostly in złoty (ZUS, taxes, living). Each transaction can cost you in three places: receiving the international transfer, converting the currency to złoty (the spread), and card spending abroad. An account that is free "inside" can be costly precisely on currencies — which is why what counts is the total cost of handling your currency, not the maintenance fee.
What to look for in a multi-currency account
- A multi-currency account — the ability to hold EUR/USD/GBP balances without automatic conversion on every inflow.
- The FX spread / conversion rate — often the biggest hidden cost; the gap between the bank's rate and the market rate can exceed all other fees combined.
- International transfer costs (SWIFT/SEPA) — SEPA in euros is often free, SWIFT usually paid.
- A multi-currency card — paying and withdrawing in currency without double conversion.
- Integration with payment platforms — if you use intermediaries for foreign invoicing.
For an IT contractor the real ranking looks different from a generic "cheapest business account" — an account with a maintenance fee but an excellent FX rate can be cheaper than a free account with a wide spread.
A bank account vs a currency fintech
Contractors often combine two solutions: a business account at a bank (for ZUS, taxes and Polish settlements) and a separate currency tool for cheap conversion. This is legal and common, but understand the trade-offs: a bank gives full domestic service and simple bookkeeping, while specialised currency services often give a better rate. The choice depends on the scale of your foreign settlements. Either way, register the account you use for business in CEIDG and — if you are an active VAT payer — make sure it appears on the VAT white list.

Currency traps and hidden costs
- Spread instead of a fee — an account advertised as "free" can earn on the exchange-rate margin; calculate the cost on your real monthly inflows.
- Automatic conversion — some accounts convert every EUR inflow to PLN at the bank's rate; a multi-currency account avoids this.
- Double conversion on the card — paying in a foreign currency from a złoty account can be converted twice.
- SWIFT fee options (OUR/SHA/BEN) — establish who bears the costs, because it affects how much you actually receive.
FAQ
Do I need a separate currency account?
Not always — it depends on the scale of your foreign settlements. With regular EUR/USD inflows, a multi-currency account or a specialised currency tool usually lowers costs.
Which costs more: the maintenance fee or the spread?
With regular conversions the spread is often far more expensive. What counts is the total cost on your actual amounts.
Can I have a bank account and a separate currency tool?
Yes, it is a common and lawful setup. Remember to register the accounts you use for business in CEIDG.

FAQ
Does an IT contractor on B2B need a separate business account?
The rules don't explicitly require a 'business' account, but B2B transactions above PLN 15,000 must go through the entrepreneur's payment account, and VAT-account payments (split payment) require a business account. In practice a separate business account is almost necessary and keeps settlements clean.
Is a business account for a sole trader free?
Many banks offer free business-account maintenance for sole traders, especially in the initial period or conditionally (inflows, card payments). Compare not just maintenance but also transfers, a currency account and terminal costs if you'll need one.
Can I invoice in EUR/USD for a foreign client?
Yes. Many IT contractors on B2B invoice foreign clients in foreign currency — a EUR/USD currency account then helps avoid double conversion. Check whether the bank offers a currency account and at what rate it converts.
