Best business bank accounts for small businesses

A business account keeps company money apart from your own, and it is the base for cards, payroll and invoicing. Most online options are built for one market, so where you are registered narrows the list.

A business account is where your income lands and your costs are paid from, and it is the base for cards, payroll and invoicing. Online providers are quick to open and cheap to run, but they differ in how they are licensed and how your money is protected.

We compare six accounts across the US, UK and Europe. Each pick says who it suits and its main limit, and the guide below explains how to check protection. If you also need cards, Wallester offers a free plan with IBANs in 10 currencies and virtual and physical cards, and can sit alongside a local account.

Choosing

How to choose

Four checks narrow the list quickly.

Where is the business registered?

Most online providers serve one country or region. Check yours is eligible before you apply.

Is it a bank, or run through one?

Some providers hold a banking licence and others work through a partner bank. Check how deposits are protected in your country.

What fees will you actually pay?

Look at monthly fees, card and ATM fees, and charges for international or same-day transfers.

What does it connect to?

Accounting software, payroll and card tools that sync with the account save a lot of manual work.

In depth

Choosing a business bank account: types, protection and what to check

Why keep a separate account

A business account keeps company money apart from your own. It makes bookkeeping and tax simpler, gives lenders and customers confidence, and is often required for a limited company. It is also the base for cards, payroll, invoicing and payment tools.

Three kinds of provider

  • Traditional banks, which are licensed and usually covered by a deposit insurance scheme.
  • Online fintechs that offer accounts through a partner bank, where protection often depends on that bank.
  • Electronic money institutions, which usually keep customer funds in safeguarded accounts rather than lending them out.

These are protected in different ways, so check which type you are dealing with and how your balance is covered.

What to compare

  • Monthly fees, and which services are charged separately.
  • Limits on transfers, cash deposits and card spending.
  • Fees for international and same-day payments.
  • Cards, including how many you can issue and what they cost.
  • Connections to accounting and payroll software.
  • Whether lending, overdrafts or other credit are available later.
  • How support works when something goes wrong.

What you need to open an account

  • Company registration documents and details of the legal structure.
  • Identity documents for directors and owners.
  • A business address and proof of it.
  • A description of what the business does and where its income comes from.
  • Your tax identification number where required.

Online providers can verify in minutes to a few days. Traditional banks can take longer.

Common mistakes

  • Opening an account only on the basis of a free headline price.
  • Holding all the money in one place without checking how it is protected.
  • Mixing personal and business transactions.
  • Not planning for international payments until they are needed.
  • Choosing a provider that does not connect to your accounting software.

Using more than one account

Many small businesses keep an operating account and a separate account for tax or savings, so money for tax bills is not spent by accident. Some providers let you open several accounts under one login for this.
