Our verdict on each
Mercury
Mercury in the United States is a fintech business-account platform with cards, invoicing, bill pay and spend management. It offers team access roles and syncs transactions with QuickBooks Online, Xero and NetSuite; partner banks remain distinct from Mercury.
Tomorrow

Pros and cons
Mercury
Pros
- Business tools and accounting integrations are described.
Cons
- Mercury is a fintech platform, not itself a bank
- partner-bank protections are not platform guarantees.
Tomorrow
Pros
- The balance is protected at EU DGS up to EUR 100,000
- Support runs on chat, email and help centre, which suits readers who prefer writing things down
- Features listed for the brand include free atm, joint account and digital only, and the free ATM allowance is €1
Cons
- The rate type is variable, so the interest you earn can move rather than being held for a set period
- Support runs on chat, email and help centre only, with no phone line for anyone who would rather talk
- The savings pot only works alongside an open Now, Change or Plus current account
Who each suits
Mercury
Who it suits
- US businesses comparing account-management, team-access and accounting-sync tools.
Who should look elsewhere
- Businesses requiring Mercury itself to be the deposit-taking bank or a platform-level protection guarantee.
Tomorrow
Who it suits
- Savers who already hold a Now, Change or Plus current account and want savings in the same app
- Anyone who needs to dip into savings without notice, with interest credited monthly
- Euro-area readers who want local payment details, since the account issues a local IBAN
Who should look elsewhere
- Plazo ES, listed at 24.19%, if the headline figure matters more than getting at the money
- AXI Card Tarjeta y Credito at 21.59%, a card and credit offer rather than a savings balance
- PayPal Colombia at 3.3%, whose rate is close to Tomorrow's, so the switch needs another reason
