GoCardless Plus is our new plan to complement our Standard and Pro packages. It allows businesses to have their name on the customers' bank statement (a Service User Number) with no mention of GoCardless. The pricing is the same as our standard package with an additional monthly fixed fee of £50.
Why you need to update your integration
When a Bacs merchant upgrades to Plus and receives their own Service User Number, in the background we have to replace all their existing mandates with new mandates to account for this change. This means that the mandate IDs that you have previously stored will be replaced with new mandate IDs
How to update your integration
If you receive a `mandate_replaced` event for a mandate that you recognise, you should update your records so that you are storing the `new_mandate` ID from the event’s links instead of the old one.
If you try to create a payment or subscription and get a `mandate_replaced` error, you should update your records so you are storing the ID included in the error response (as `links[new_mandate]`) instead of the old one.
Please contact us as soon as you've made the change so we can upgrade any of your customers on the waiting list.
