Our experience is that Pro and Premier data files start to take a long time to run reports at the 150-200 MB size. In addition, Pro and Premier become more susceptible to data corruption and other funky issues if they get to be too large. The Enterprise version was designed to handle a much larger data file. There are some businesses running smoothly today with data files over 1 GB. 

There is no hard and fast rule on this topic. Nor is there any way to know exactly how many invoices, estimates, etc. will get your data file to become “too big”. However, these rules of thumb relating to the 150–200 MB max file size for Pro and Premier have served our clients very well.

The question is which QBD year version you have now. If you are using QBD 2019 or later, you may have better options to condense your file.
