I've come to share some insights regarding your file size concern, @apate.

Yes, you are correct. There are no actual limits on the size of your company data file, but performance may be hindered if your network is not capable of handling large data files. QuickBooks' performance decreases as the size of the company file increases.

The ideal use of QuickBooks Desktop is to keep at least two years of detailed transactions in a company data file so that you can compare reports and have prior-year project information. Thus, there's no recommended file size since businesses track different information.

If you're experiencing any performance issues and you wanted to reduce your file size, you may condense the data. Here's a link that provides complete details on how to perform this process: Resolve QuickBooks Desktop performance issues: Manage your data file.
