Our integration with GoCardless enables you to accept Direct Debit transactions from any UK bank account that allows Direct Debit. This is typically from any current account (not a savings account!) however, there are some accounts out there that do not allow Direct Debits - your members will typically know if that applies to their bank account.
We currently only support Direct Debit payments in GBP, but we have plans to expand to multiple currencies very soon. Watch this space!
