I have an customer within my Quickbooks accounts who I have billed. I wish to amend them to a client so that I can sign them up to a Quickbooks subscription. Can I?

Hello Richard, Thanks for reaching out to the community, we're happy to help guide you on turning the customer into a client. To do this go to clients on the left-hand side menu( you will see the customer in the list) then hit on edit client>scroll down to products>change to subscription>select the product>set up the master admin and continue with the next steps. Any Q's just ask
