What your customers get on day one

Apps in your brand

iOS, Android and web apps in your colours and on your own developer accounts, localised for the markets you serve.

Sign-up in minutes

Separate onboarding questionnaires for individuals and companies, identity checks through the verification provider you connect, and limits applied from the first login.

Spending accounts with UK details

GBP accounts with their own sort code and account number through your banking partner, plus EUR and other currencies for customers who travel or get paid abroad.

Mobile banking app with a branded Visa card added to Apple Wallet
Mobile banking app home screen with balance, Add money and Send buttons

Debit and prepaid cards

Virtual cards issued in the app the moment an account opens, physical cards on request, and Apple Pay and Google Pay. The issuing contract is yours.

Savings pots and FX

Vaults to set money aside and in-app currency exchange at the rates you configure.

SME accounts

A business version of the app with company onboarding, team members, batch payments and approvals.

What this licence does not cover

  • A current account protected by the FSCS. E-money balances are safeguarded, not covered by deposit insurance, and your app copy must not suggest otherwise.
  • Overdrafts or loans funded from customer balances. Consumer credit needs its own FCA permission and separate funding.
  • Interest on balances. You can offer savings pots, but an EMI cannot pay interest on e-money.

What the regulator asks about your IT

Each requirement, what the platform gives you for it and who owns it after launch.

Screen-by-screen walkthrough of the apps and the onboarding flow, so the FCA sees exactly what a customer does.

Applying to the FCA as an EMI? Show them the app.

An FCA case officer reads a lot of business plans. A working app in your brand, with real sign-up and payment flows, answers many questions before they are asked. Your lawyers handle the legal side.

01

A platform you can demonstrate

A configured environment in your brand to show the regulator, not slides.

02

The technical part of your application, prepared

IT and security policy, outsourcing, business continuity and the customer journey sections of your FCA file.

03

Providers lined up

Accounts, safeguarding and UK rails through partners including ClearBank and Clear Junction.

From FCA file to app store

A Manchester team wants a money app for students: GBP account, a virtual card on sign-up and a pot for rent. We start with a branded test build on their phones, which they use in pre-application meetings and attach as screenshots to the programme of operations.

While the FCA assesses the file, their designers finish the brand, the compliance lead writes onboarding questions for students and international students, and the apps go through App Store and Google Play review under the firm's own developer accounts. Release is held until authorisation lands.

If you have your own front end and only need the ledger, see core banking for UK EMIs. The licence itself is covered in our UK EMI guide.

FAQ

Yours. The apps are published under your developer accounts, with your name, icon and support contacts. Crassula does not appear to your customers.

Core banking is for EMIs that build their own apps and need a ledger and back office. This page is for teams that want the full product, including the customer apps, onboarding and cards, ready to brand.

Yes. Questionnaires per client type are configured from the back office, so your compliance team can change them when your risk assessment changes.

No. An EMI cannot pay interest on e-money, and e-money is not covered by the FSCS. Your app should explain that funds are safeguarded instead. Our CASS 15 guide describes how safeguarding works now.

The programme of operations, how customers authenticate, how you protect payment data and who runs the platform for you. We prepare the technical parts and show the live apps if the FCA asks.

Some teams start under a licensed partner and move to their own authorisation later. This page assumes you hold, or are applying for, your own FCA EMI authorisation. Request a demo to talk through your route.
