Clients with our Basic plan may only use one billing method at a time but can always add back-up billing methods in case there’s an issue with their primary billing method. The client will have to choose from payment methods listed as available in Add Method menu in their account Settings.
I asked this a while ago but got no response. When did the payment processing fee become 3%? It used to be 2.5% or 2.75% (can't remember which), then it just increased without any notice ... unless I missed it.
This information was communicated to clients in the email notification they received regarding the new client membership plan and also the new payment processing and administration fee was noted in Lena's Community announcement post.
