can I set up a line of credit or debit for specific customers. Is this possible? So basically, when they reach that specific limit, QB will send a statement automatic

Currently, QuickBooks Online doesn’t have the ability to automatically send statements to your customers when they reach their credit limit, Move.

In the meantime, consider running an A/R Ageing Summary report and scheduling it daily. It will help you determine customers with outstanding balances or credits that need to be settled.
 

Also, I recommend exploring third-party apps that integrate with QuickBooks Online to automate the process of sending statement reminders to customers when they reach their credit limits.

If you have additional questions, feel free to reply here. We’ll address them as soon as possible.
