"This is applicable in both QuickBooks Online and QuickBooks Desktop." Can you elaborate on this? I looked at the link about sub customers but that is not an option for me (QuickBooks Mac 2019). If Quickbooks Mac 2022 has this feature I could upgrade, but going online is not an option as I need the ability to work offline.  Right now my only option that I've found is to change the names of inactive customers to that of another inactive customer and merge them.
