Correcting what I just posted-  I do have this exact same problem as you do in quickbooks online.   I have the opposite in QB DT.   I just took over my dad's business, which is a rental property with multiple tenants.  I just migrated his QB DT into QB Online and suddenly find myself in this same predicament that you've described here.  We don't send invoices either since our tenants just send us a check for us to deposit every month.  Now, in QB online, I can't see these names anymore, when in QB DT the report listed these names!  Has anyone been able to generate a report that shows the customer names?  This is terrible. My data goes back multiple years and now I can't see any names in these reports anymore.
