We are in the investigation stage of migrating from Quickbooks Desktop to Quickbooks Online. We met with a sales rep and I had questions about the Target limit. The help guide here on this website say that you need to have under 750,000 targets to upload your data file into QBO. We're at 850,000 so we've got some work to do. 

I asked the sales rep if this 750,000 limit is just for transitioning, or is this the limit for QBO going forward. For example, if I get the file down to 749,999 targets, migrate the file to QBO, and then add two targets, is my QBO environment then full and I can't work anymore? To my surprise, the sales rep said yes. 

This seems crazy. If this is the case then the guides should say something like "get your file down to as few targets as possible", because if you  just get it "under 750,000", then QBO will be useless very soon. 

I'm asking for a sanity check here, is this *really* how this works? Can I get my file down to 749,999 and then continue working, or should I just start from scratch?
