Is there an add-on to Quickbooks to easily track hours logged against customers then convert these to invoices as a batch. I trialed tsheets and its not perfect for me.

Based on my understanding, TSheets does track hours logged against customers then convert them to invoices as a batch. However, depends on your needs, you might have do some customisation. 

I would suggest giving our support team a call and discuss in details. Here is our contact us page for your reference:
