London and Zurich / GoCardless Migration Glossary of Terms

During the GoCardless to London & Zurich migration process there will be some banking terminology used which isn't often used in every day language. So to help guide our customers through this process we have put together this handy glossary of terms.

And remember, if you have any question then please ask for help from the LoveAdmin support team!

This glossary has been put together with help from London & Zurich.
