How do you send multiple invoices to one client

Hello Userstevetash59, 

Welcome to the Community page, 

There is no way to be able to send multiple invoices to one client in QBSE, it would be a case of having to send them one by one to them within the system or you could export them all as a pdf and then attach them to your own email outside of QBSE and send them to the one client.
